thank you also to derek van dam and to john berman in tallahassee and derek in tampa. we're giving you the scenes of what's happening with this category 3 now, hurricane idalia, back to you, phil, in the studio. >> spanning 150 to 180 miles of the west coast of florida, all of which is seeing effects even though the big bend region is really kind of the direct path. keaton beach is what the florida emergency management division official who leads that organization was saying earlier today, sara, we've been watching throughout the course of the morning, what you've been seeing on the ground, the water, the flooding, we've been talking about storm surges, very, very dangerous, potentially 12 to 16 feet. as you noted it's now category 3 storm, not category 4, but in talking to the hurricane storm director earlier, he made the point, we're talking about five to ten miles an hour here, not a dramatic difference when you're talking about the scale of the storm we're seeing, particularly in places like steinhatchee where bill weir is, the entire team coverage going forward, a

new forecast from the national hurricane center just moments ago and i want to go straight to derek van dam who is on the ground for us in tampa. s sara sidner is with us as well. derek, you understand what these forecasts mean better than anybody. what does this tell you? >> reporter: yeah, exactly what we feared, the rapid intensification now to a category 4 major hurricane idalia. and eyeing the big bend coast. but where i'm standing now on bay shore boulevard in tampa bay is proof that you do not need to be near the center of where the storm makes landfall in order to feel its impacts. what you are looking at is storm surge from tampa bay. this is what we were forecasting. 4 to 6 feet and it is certainly being realized. this is bay shore boulevard and you can see the waves coming crashing over the seawall. we get sprayed every 30 seconds or so. here comes another push of water. remember what is happening here, we have a high tide that just occurred at 4:00 this morning. but we also have inland flooding. and that with the surge of water from the eastern gulf of mexico, all of these worki

now, i want to get straight over to derek van dam. he is joining us from tampa. every hour we get an update from the national hurricane organization. please let us know what is the latest forecast for hurricane idalia? >> reporter: well, you are starting to feel the system as well as much as we are. but we are on a highly susceptible road, this is called bay shore drive. and we're approaching high tide which is roughly 4:00 in the morning, 4:07 to exact. and we're staring down the eye of a monster. latest satellite shows it is 125-mile-per-hour, a powerful category 3. and we're teetering on a category 4 hurricane here. but i want to show you around, look at bay shore drive, this is normally filled with vehicles closer to around 5:00 in the morning or approaching early morning rush hour in tampa. and of course that won't be taking place today because you cannot drive over this road. locals understand and know that bay shore drive floods regularly. but this is tidal storm surge and exactly what the national hurricane center had warned the public about, to stay away

i think we're going to be going to derek van dam, derek van dam and bill weir, one of the two, i'm going to let you take it back, because at this point i can hear nothing but wind and rain. >> toss it over to derek van dam. derek, we've been talking the you throughout the course of the morning, we've seen the intensification of the flooding, of the rain and of the wind and in the last two hours, the scale of the flooding in terms of where it is on your legs is undeniable. tell people what you're seeing, and why that's happening so far away from the center of the storm. >> reporter: yeah, you put it so well there, phil, we are 125 miles southeast of the most powerful part of the storm. so, my point being that you don't have to be so close to the center of the storm with the strongest winds to get the greatest impacts. let this scene speak for itself, right, we've got flashing lights behind us. tampa is behind me. this is bay shore boulevard, and we are getting these intermittent powerful feeder bands from the hurricane. again, we're 125 miles away. that is an angry tampa bay, and this sto

let's bring in derek van dam standing right next to me. we're standing in -- this is the confusing thing for a lot of people especially visitors who are not familiar with what happens in a hurricane. you look behind you and it looks like paradise because it is. it is absolutely gorgeous. but in a split second, as these bands come, you can get slapped with very high winds and the rushing water. >> yeah, especially this coastline is so vulnerable to the storm surge. we'll get into the details about that. sara, it's literally off to the races for hurricane idalia now into the open waters of the warm gulf of mexico. and we talk about that being jet fuel because water temperatures there are literally 2 to upwards of 4 degrees fahrenheit above where they should be this time of year. that is just going to aid in this intensification process. you can see on my graphics, there's the hurricane there. it has a general northerly trajectory. and it's moving at quite a clip. 14 miles per hour. that's significant because that means it's going to bring th

wa i /* i want to go he go to derek van dam. he has another u view as he watches this hurricane get ever closer. >> reporter: chthis out. we are in clearwater. you were talking about the warm gulf of mexico waters. we are beyond bathtub waters. we are in hot tub territory. temperatures are running two to three degrees fahrenheit above where they should be this time of year. that's like jet fuel for an incoming area. it will feed off those warm waters. how this coastline is so susceptible, particularly the west coast of the florida peninsula, the gulf side, right, and into the big bend area. an aerial perspective gives you an idea of what we're talking about here. so side by side, hopefully, you have this up, you can see the storm surge projections. 8 to 12 feet near cedar key. that is incredible. look at the vast miles of flat beaches that go as far as the sky can see. clearwater to the north. we are in sand key to at south of this. and we are going to get on the granular details. the national hurricane center has this storm sur

let's go to derek van dam who is in tampa who that be walking along the river all morning long. k, what are you seeing now? >> reporter: john, it is so important to point out that a year ago when hurricane ian came through this general area, it actually sucked the water out of tampa bay that's over my left shoulder where people could walk out into the bay several hundred yards. that's what some of the locals here have been telling me about, they remember that. this is a completely different storm. we never want to compare one hurricane to the other because they bring their own stories, their own threats, but it's all about the position of where that hurricane eye wall goes. so with ian, they were on the backside of the storm here in tampa. with idalia, we were on the forward, surging, pushing side of the major hurricane. just kind of puts it into perspective, what the wind direction does and how that impacts the storm surge. this was the strongest storm, strongest hurricane to impact the big bend area in over 125 years. we have had three landfalling hurricanes in the state in the

meteorologist derek van dam is with us now. derek, what's the latest?: yeah. what people need to know is it strengthened to a hurricane officially at the 5:00 a.m. update this morning. one interesting thing to note as well is it is on its forward move. we're seeing that northerly progression at 14 miles per hour. that means it is picking up speed and will continue to do so before its landfall. now, look, it has a lot of open water to traverse first. and that water is extremely warm that will allow for what we call rapid intensification, a strengthening of the storm. we have seen this story play out time and time again, hurricane ian last year, we remember that. here is the latest radar. you can see how the western slopes of cuba are getting clobbered right now with heavy rain bands. havana included in that category 1 hurricane moving into the open waters of the southern gulf of mexico and will start to see those rain bands impact places like ft. myers, naples and into tampa as well. storm surge flooding, we have the red highlighted there, 8 to 12 feet,

i want to get to derek van dam in tampa. he has been watching this storm. he has been watching it from the satellite images and from the ground where parts of tampa are inundated with that storm surge, with that floodwater. derek. >> all right. sara, so we are going to step away from this -- the seriousness of the storm for a second. you've got to bear with me. this is something you don't see everyday. what are you doing? literally, we are --? a very new way to beat rush hour traffic on bayshore boulevard in tampa. these guys are kayaking down this major thoroughfare over my shoulder here. i mean, look at that. i don't want to minimize the serious nature of the storm, but this is what people are dealing with in tampa as we will speak. people coming out to be more spectators than anything. the storm surge threat has been realized. 5 1/2 feet at one of the tidal gauges down the road from us, and that is why we see this storm surge event unfolding across much of the big bend to tampa bay where i am located. that is an angry ocean there. you can see the waves j

you look at those pictures from derek van dam and the image behind me, and it is attractive.ou want to come here, you want to see this beautiful beach. it is quiet, there is no one here, it is gorgeous. but the weather is going to change. and when it does, it will be rapid and when it does, it will be dangerous. not necessarily because of the wind, although you will definitely notice it, but because of the storm surge. derek talking about the fact that it could be between 6 and 12 feet of storm surge. that would be double the side of derek himself where he is standing. water coming up that high and coming at you fast. it is an absolutely imperative that you try and get your things together, get your pets ready, and get to higher ground. authorities have been saying that you don't have to travel hundreds of miles. make sure that you fill that gas tank up. but you don't have to go hundreds of miles or to another state. you just have to get out of the low lying areas. areas that you are seeing right there. the beach, it is flat. when these waters get pushed up on to the beach, t

let's go to derek van dam who is there. derek, what are you seeing? >> well, john, exactly what you're saying, this proves the point that you don't need to be near the center of the storm to feel the impacts of this major hurricane which now, i believe, is a category 2. let me set the stage here. this is bay shore boulevard. tampa directly over my shoulder and a very angry tampa bay over my left shoulder. we've been watching the water pound in across this beautiful boulevard. as john was mentioning this is a more highly populated area compared to the cedar key region, for instance. remember that this is the strongest hurricane to make landfall in the big bend in over 125 years. so why are we here? we are talking about the storm surge and we just a moment ago before crossing to me we saw high water rescue vehicles from the tampa bay police drive behind us so they are out investigating these communities directly impacted here along the shoreline of tampa bay and what we've noticed here is the water receding by, let's say, 6 inches, perhaps a foot, but w

derek van dam shows us more of the damage and how authorities are responding. >> reporter: tonight, fires on the island of maui continuing to burn as new federal help is now being dispatched amid unprecedented widespread destruction. scenes like this becoming more common. businesses melted. historical sites gone. homes reduced to ash and smoke. hospitals are overwhelmed. officials say hundreds of families are displaced. >> everybody in our neighborhood lost everything. >> reporter: mark's home in lahaina is gone, as is much of the tourist destination and economic hub. steffel making a harrowing heartbreaking escape. >> we ran downstairs and grabbed the dogs and cats. and we lost the cat and the dog because of just confusion. and the fire just engulfed our house. >> reporter: officials say winds associated with hurricane dora helped fuel the fires. these before and after images near lahaina shores beach resort are staggering. same with this stretch of beach, where a number of buildings are simply gone. today president joe biden approving a disaster declaration for hawaii, providing federal

all right, derek van dam, thank you very much for that report. more on the fires i want to bring in our meteorologist chad myers. he's joining us from the cnn weather center. how are the winds contributing to this ongoing danger? >> two things combined, wolf. a high pressure to the north up here. there's hawaii right through there and hurricane dora. a category 4 hurricane that passed south. you would think hundreds and hundreds of miles would be far enough away, but with that high there and that low there and the funneling effect, it wasn't. 82 miles per hour was the highest gust, but there finally goes dora, 130 mile per hour storm and it will get into cooler water and die off. the farther it goes away the more the winds will die off. we will lose some of that difference between the high and the low pressure, all of the smoke coming off maui in the overnight satellite picture. i looked at this this morning, and i saw all of these orange spot, wolf, and i thought, oh, we must be looking at a forest. this must be some burning trees. now in the de

let's bring in derek van dam, he is live in the cnn weather center. this storm really seemed to come out of nowhere, developed quickly and with surprising power. >> yeah, hurricane force gusts in fact some reports over 75-mile-per-hour. but what is most astounding to me, we have over 600 reports of severe weather including one confirmed tornado with the number likely to go up. but look at that, over 500 reports of wind damage and wind reports. mine this, is blanketing much of the eastern sea board, some of the heaviest populated areas of the united states. and so anywhere from atlanta to the nation's capital and outside new york city.threat diminishins the east coast. in arkansas there is a severe thunderstorm watch until about 8:00 a.m. central time. and by the way, some hefty storms moving through oklahoma city as we speak. so the threat today largely across the plains. and the deep south, this is the remnants of the cold front. jackson, mississippi to tallahassee, florida. isolated damaging wind gusts, large hail and can't rule out a possibility of

derek van dam has the latest. we'll start with stephanie elam live in cathedral county, southern california. what are you seeing? >> a whole lot of water. i want to show you. these people in the car, they've been out here for hours. i'm standing here in a few inches of it and because of that, their car has been stuck there with water in the engine and there's too many rescues going on. that's not just the picture here, it's happening throughout southern california. this morning palm springs is under a local emergency order as heavy rain from hilary is causing dangerous flood conditions prompting three swift water rescues. >> we're asking residents to stay inside, stay where they are. >> reporter: the mayor's warning is because of a situation like this. a pickup truck stuck in the middle of a street surrounded by deep rushing flood waters. the driver was not injured but the california highway patrol closed the road to prevent others from crossing. throws flood waters so powerful a refrigerator was seen rushing away

we're shook to our core. >> reporter: derek van dam, cnn. >> if you would like information on how to help, go to cnn.com/impact. there you will find a list of vetted organizations that you can check out. >>> the u.s. supreme court is blocking oxycontin maker purdue phrma from moving forward with its opoid settlement saying it will hear arguments in the case this december. until recently purdue was controlled by the sackler family who withdraw billions before filing for bankruptcy. under the bankruptcy agreement the sacklers would be protected from all future lawsuits related to the opoid epidemic. the settlement between purdue and several u.s. states was agreed upon in march after years of negotiation. ohio's attorney general said he is disa pointed that the supreme court is getting involved. >>> this war is fought on the ground of our streets of our cities and counties. it is so important to get the money flowing. it has been since 2019. >> the u.s. government calls the arrangement that would protect the sacklers an abuse of the bankruptcy system. >>> u.s. screen writers and hollywo

cnn's derek van dam is with us now. not at all under control.ere to turn the corner with these fires? >> well, we've got a tough 12 hours ahead. winds are gusting to 66 miles per hour within the past hour. so clearly, still funneling and fueling some of these flames. so what you're looking at and the video you saw directly before me is from la haina, on the western side of maui. you have to understand that this is the economic hub of maay and this is where residents live and this is where tourist goes to vacation, you know, with 20% of the island without power, this is a significant, significant event for the island of maui and it's also hawaii. we've heard emergency declarations issued by the lieutenant governor of hawaii, from that burn scar or this hot spot on the satellite imagery. you can see the direction of the smoke. this is showing you how strong the winds actually are. what's taking place here? why are we getting the strong winds over the hawaiian island? it is the high pressure squeeze between passing to the north and that's hurricane

let's go back to derek van dam. what's the latest there? have more information to pass along. first, i want to give you perspective of what's happening. well away from the center of hurricane idalia, this is in the key west area. we're all familiar with this shot. you can see the dark skies and also the waves getting choppy. what i want to point out is that this is roughly 150 to 200 mile was from the strongest part of the strengthening hurricane that we're talking about. so my point being is that impacts will be felt well outside of the center, where this makes landfall. 85 mile per hour winds sustained, gusts over 100. this storm continues to strengthen. and there's explicit language from the national hurricane center they anticipate rapid intensification because it's feeding off of the warm waters that you see behind me. this is a live look at the radar. you can see some of the rain bands making its way into key west, the florida keys, the west coast of the peninsula. we're about an hour, maybe 45 minutes away from our first tropical sto

you can see derek van dam in the middle of it.solute flooding. you can see derek van dam in the middle of it. >> just 24 hours ago. >> what is the situation this morning after we all witnessed that all of yesterday? >> the flooding out here in tampa has receded. and the cleanup effort really across hillsborough is well underway. the lone mand toir evacuation order was lifted yesterday. and the bridges that connect tampa out to st. pete and clearwater have reopened. to the north of us, it's a very different situation. thousands of homes have been damaged by flooding there. >> hu hawaii barrelled through making landfall neark keaton beach. this right here, i toebt know if i'm going to have a house to go home to. >> reporter: the you of the storm ripped through florida's big bend region with sustained winds of 125 miles per hour. resulting in a once in a century weather event. >> it was bad. it was heavy winds. worst i have ever been in. >> reporter: the category 3 storm left homes demolished and streets flooded. >> we clearly have significant damage

so let's get to meteorologist derek van dam to get a sense of where the storm is, the timing, and where? >> you know, i like that you showed some of the pictures coming out of cabo san lucas because you can see cabo on our weather map, and here is the location of hurricane hilary. this is roughly 300 miles away. so we're starting to see an expanding wind field. some of the outer rain bands from the storm already impacting this major tourist destination. that's in the southern california, baja peninsula. where is the storm heading from here? let's take it further into the future. official forecast track, we're waiting for that 11:00 a.m. eastern/standard time update. one thing's for sure, we have a weakening storm in this forecast. as it approaches southern california, it will likely be a tropical storm. so let's time it out. if you're in san diego, perhaps los angeles, ventura county, for instance, these areas susceptible with gusty winds by sunday that could gust over 50 miles per hour, especially in southern sections of california. we want to keep an eye on that. the higher elevations

. >> let's go to meteorologist derek van dam in the weather center.hat is -- described there is dire. the governor says that never happened before, wildfires created, spurred by a hurricane. >> yeah, victor, it's important to clarify it's kind of a direct cause of the hurricane. we will get to the details on that in a moment. i spoke to the chief emergency management operator from maui, and what she told me is this an all-hands-on-deck situation for their firefighters and the state personnel as well. there are three active wildfires on the island of maui. the western side of maui is where they are focusing a lot of attention because the wildfire that is there is currently burning near residential and hotel districts. so some of the more populated areas of the island. they are currently, there are 14,000 people without power. that's roughly 20% of the entire island. we expect that number to continue to grow because we have seen scenes just like this. look the wildfire smoke just billowing out and later on in the imagery you can see some of the resident

derek van dam is tracking the storm has the latest on the forecast. mike va layer yes is in san diego. let's start with stephanie elam live on the ground in cathedral city. you've been there all day, overnight into the morning. what are you seeing? still water on the roads? >> reporter: oh, so much water. victor, take a look down here. i'm actually standing next to the edge of the curb here and i tried to put my toe down to feel how far that is and i can't reach it. that's how far it is. there was a car here, they got a tow truck. it took them four or five hours before the tow truck could get here. this is happening all through the desert towns because there was so much water in a short amount of time. this morning palm springs has heavy rain causing dangerous flood conditions and prompting three swift water rescues. >> we're asking residents to stay inside, stay where they are. >> reporter: the warning be is because of a situation like this. a pickup truck stuck in the middle of the street surrounded by deep rushing flood waters. they're so powerful

we begin with our meteorologist derek van dam. i think anyone waking up this morning hearing a hurricane is heading to southern california will be very confused, as i was. it doesn't happen a lot. >> yeah, you have to go back to 1939, the last time we had a tropical storm made landfall in southern california this is significant and people are going to be caught off guard with this system. we're closely monitoring it, but this storm intensified by 75 miles per hour just in the past 24 hours. it is a cat 4, winds right now at 145 miles per hour. when will we feel the impacts? the baja peninsula here, this is part of mexico, of course, they'll feel impacts by saturday morning. but as early as saturday evening into southern california, certainly into the day on sunday, and once again on monday across much of the southwestern u.s. but this storm is going to encounter some significantly cooler water compared to where it's moving across right now. and this is going to significantly weaken the storm as it approaches california. it's likel

meteorologist derek van dam is closely following the path aina tasha chen has a look at storm preps in los angeles. derek, let's start with you at the cnn weather center. i can't believe we're talking about a hurricane and preparations for it in los angeles but we're talking about a very unusual hurricane here. what can you tell us about hilary, when can we expect to see it hit the u.s.? >> look, jim, i think what people need to recognize is that this storm is picking up forward speed very quickly. if you kind of tune in intermittently over the past 24 hours you may have thought, hey, this is more of a sunday night into monday time frame. the fact is that the storm sped up and this is going to be a sunday storm for southern california and much of the southwestern u.s. as well. very important for people to understand that we are already seeing the impacts across the interior of southern california. 115-mile-per-hour winds with the storm and radar coming out of southern california and generally dry into the coastal areas but look what's happening across the mountain ranges and into centr

derek van dam is there. what are you seeing?wind continues to push up the water from tampa bay as well, john. we are getting now these intermittent tropical feeder bands and what was completely visible across tampa bay has now been obscured by heavy sheets of rain coming in. it's raining at quite a clip. probably a good half an inch to an inch per hour. this will cause localized inland flooding. this is all working together to create the very difficult storm surge conditions that you see unfolding behind us on bay shore boulevard. this area floods during rainy days. it happens. but this is in conjunction with the surge of water that has been pushed up with this major hurricane. the inland flooding meeting it at the same time. and then also the exaggerated tides from the supermoon and the full moon that's happening as we speak. we just went through the low tide cycle. that was at 7:56 this morning. we're working our way back up into high tide. so the concern here is that the surge that already broke record levels -- one of those

derek van dam, thank you very much.s we mentioned earlier, there are already evacuation warnings in place for parts of southern california. this could be the first time a storm like this has hit the state in more than 80 years. the california national garland guard is standing by ready to help. a state emergency official tells cnn it's an all hands on deck situation. >> we have swift water rescue teams, high-water vehicles positioned all over southern california. we've also moved millions of pieces of commodities into the region, so cots, blankets, food, water, in case we need to set up shelters. we really want to be on the front foot of this and that's what's happening now. >> cnn's natasha chen is live in los angeles. natasha, looks like the winds are picking up there a bit. how are things looking? >> reporter: picking up just a little bit, jim. and we're expecting, in the next hour to three hours that north of us in antelope valley, they might see some scattered thunderstorms as the outer bands start coming in this d

our meteorologist derek van dam tracking it all. what does it look like it's going to do? >>> this will be in a significantly weakened state by the time it impacts the southeastern u.s., that's extremely important as a weather communicator that people understand that just because we have a category 4 storm lurking off the coast of the baja peninsula does not mean we'll have category 4 winds in southern california. however, the impacts will be significant mainly because we're going to catch a large population density off guard because this hasn't happened since 1939, the last time a tropical storm made landfall. the official track shows a landfall and tropical storm, does it move inland? does it stay over open water? that's to be determined. one thing for sure, it will interact with significantly cooler ocean waters, and that will help weaken the storm as it approaches the southwestern u.s. if the track takes it offshore, so no land interaction with the baja peninsula, more of a coastal impact, so look out for large waves, coastal erosion and urban flooding possibility betw

derek van dam has this report. >>> tonight, six people confirmed dead. and a massive search and rescue operation under way in maui county, new helicopter video showing homes and businesses burned to the ground. >> my 52 years of flying on maui, never seen anything like that. >> reporter: the state is getting blackhawk helicopters to tight the fires on the big island. maui's mayor saying 2,000 people in shelters. all this has winds push across the island and fuel the flames. >> we never anticipated in this state, that a hurricane, which did not make impact on our islands, would cause these wildfires. wildfires that wiped out communities and businesses. >> reporter: lieutenant governor, sylvia luke, who is acting as the governor, as josh green treavels back to hawaii. he's going to request assistance from the white house. >> governor green and i have been talking. >> reporter: state officials discouraging tourists from traveling to the popular destination. late word that american and united airlines are cancelling all flights to maui's airport. >> this is

cnn's derek van dam is tracking its every move. derek, where is the greatest threat right now? >> the scene that you saw unfolding on your tv screens and what happens is when you get tropical moisture in a dry -- typically dry area. the ground just simply cannot absorb this amount of tropical-like downpours. we get the mudslides, landslides, the debris flows and the urban flash flooding with the impervious surfaces all around greater los angeles county. portions of i-10 have been closed near palm springs. it has been quite an overnight period. right now the latest 5 a.m. update has what is called a post tropical storm. so basically hillary now starting to lose its tropical characteristics but it is still packing quite a punch and mainly in terms of the heavy rainfall and the excessive rainfall that is running off the mountains and into the communities below. these are just kind of a scattering of some of the higher rainfall totals we have seen and these numbers will go up. look at san bernardino county. we've received over 10 inches. look at l.a. county. over half a foot of rai

derek van dam has a break down. >> it is a battle between the record ocean temperatures that help fuel stronger hurricanes versus a strong el nino that helps limit hurricane activity. just yesterday the national oceanic atmospheric administration upped the ante and increased the likelihood of an above average hurks sricane season. you can see after already having four named storms, any are anticipating for the entire season up to 21 named storms. that is a big difference from what they forecast in may. hurricanes between 6 and 11. and get this, two to five major hurricanes, that is category 3 strength or greater anticipated across the atlantic basin. typically when we have a strong he wiel nino like we do now, thn development region inhibits hurricane potential, it really kind of tears apart a hurricane. we do have these water temperatures that are running 2 to 4 and even 4 to 7 degrees farenheit above average. so we believe and so does noaa that this will actually win in this battle betweeo and record warmth. so that will help bring an above average season. here is the four named stor

so let's track it all with derek van dam. when will folks begin to feel the impact from the storm? >> depends on where you are located in the western baja peninsula, probably the next 12 to 24 hours. in southern california, saturday night as early as saturday night and certainly into sunday and monday. here it is, hurricane hilary latest 5:00 a.m. eastern standard time advisory from the national hurricane center, ups those sustained winds to 145 miles per hour. that make this is a powerful category 4 atlantic hurricane, of course it is in the pacific. steering winds have a major fang t -- factor on where the system goes and you can see the potential to impact the southwestern portion of the u.s. how much is still to be seen. we have a lot of cool water ahead of this tropical system, so we do anticipate a significantly weakened storm as it approaches southern california and extreme northwestern sections of the baja peninsula. perhaps slight strengthening within the next 12 hours. but as it keeps the colder waerks water, it will start to weaken. but the update has a tropical storm en

meteorologist derek van dam is live in clearwater for us. he leads off the coverage. derek, what are you seeing? >> yeah, boris. it is the calm before the storm, right. but the latest information that we can pass on to the viewers is that idalia is strengthening with 85-mile-an-hour sustained winds and lashing the southern portions of florida already. you saw the live view, and we will take et again from key west, and this is the indication of 50 miles per hour winds look like. that the outer band, and remember, the center of the storm now gusting over 100 miles per hour, and the official track is calling for a category 3 making landfall along the big bend, but the winds are going to be 125 miles per hour, and that is just shy of a category 4 hurricane. so we are anticipating and so does the national hurricane center, continued rapid strengthening, and it is a concern, and it is all because of the warm waters that we have behind usment storm surge, and we talk about it frequently, and the water here is literally, well, it is like a hot tub. it is not bathtub anymore, b

. >> cnn's derek van dam joins us now.i think is keep is the way is really just dawning there, so i think we'll just start to get a sense of the damage there. tell us how this happened? >> yeah, it's really becoming first light, sunrise roughly about 6:30 local time. really with this satellite imagery, you see the orange specks? these are the three active wildfires, as we go forward in time, we start to see that the hot spots aren't as bright as what they were overnight when the fires were at their maximum. what we believe is happening is with a little communication they fires are starting at least to maybe their energy and their extreme erratic fire behavior is starting to calm as the winds gradually calm in the coming hours. so that's good news. the late it's wind reports there, over 65 miles per hour, but hopefully that would improve. you're looking at lahaina. you have to keep in mind, this is the economic hub the western maui. this is where tourists go to vacation, this is where people live. this is where their busine

derek van dam is there reporting, and tell us about today, is it as bad today? >> good question, kate. today, 600 storm reports and the wind gusts knocking and toppling over trees and softball-sized hail falling from the sky, today is going to feel like a walk in the park, but it is only going to take one storm to create havoc across a populated area. and today, the threat is in new england. it is a storm in heavily populated areas in newport, rhode island and bristol, and it is moving into massachusetts and so for the next 30 minutes or so, this area could experience gusty winds in exsetsz of 50 to 60 miles per hour, and frequent cloud-to-ground lightning, and we are monitoring flood watches and warning in effect west of the boston metro area. this is different from what we have experienced and look at what the storm gusting can do, and sheering off the top of the roofs and there are reports of 600 weather reports yesterday and very active and part of the storm system is going to fuel more systems and it is so hot across the gulf states that the storms are goin

and let's get to derek van dam. a lot of severe weather on the forecast. what can we expect today?of severe storms. this time not along the east coast but across the mid mississippi river valley. this is where we have our greatest probability of severe storms. so if you are in places like memphis to nashville, perhaps into little rock, this is an area that has what is considered a level 3 of 5 from the storm prediction center. and look being at what they have detailed here. large hail, damaging winds and an isolated tornado as well. greatest possibility of tornado, right where you see this yellow shading. so southern missouri into western sections of tennessee, including the memphis metropolitan region has a 5% probability of tornadic activity. this on the 450e8 heels of the active weather yesterday. a couple tornadoes reported in massachusetts as well. they also saw heavy rainfall and you saw some of the video of flooding taking place in the state as well. over half a foot of rain fell in some locations there including the lawrence region of massachusetts. so here is the latest ra

let's go to derek van dam, who just filed this report. >> reporter: tonight fires on the island of maui continuing to burn out of control, as new federal help is now being goods patched amid unprecedented whyspread destruction. seems like this becoming more common. businesses melted, historical sites gone. homes reduced to ash and smoke. at least three dozen people have died. hospitals are overwhelmed. officials say hundreds of families are displaced. >> everybody in our naked lost everybody. mark stepple's home is gone as much of the tourist destination and hub. he made a harrowing heartbreaking escape. >> we ran downstairs, and we lost a cat and a dog because of confusion. the fire just engulfed our house. >> reporter: officials say winds associated with hurricane dora helped fuel the fires that have now impacted more than 250 structures in lahaina, plus hawaii's big island. these before-and-after images near a beach resort are staggering. same with this stretch of beach, where a number of buildings are simply gone. today president joe biden approving a disaster declaringation for haw

derek van dam has the forecast. tell us, how long is this heatwave really expected to last?finitely here today and tomorrow, but there is relief in store. look at the scope and magnitude of this heat alert across the central u.s. this stretches from louisiana all the way to minnesota, west virginia, westward toward the dakotas. this is covering over 110 million americans. and over 20 states impacted by this impressive heatwave. and by the way, places like chicago and indianapolis, you may reach 100 degrees for the first time in over a decade, that kind of puts it into perspective how serious and the scope of this heatwave actually is. so going forward, we have the potential for 400 record highs and record maximum minimum temperatures overnight. record low temperatures overnight i should say. record low maximums. a tough one. 110 degrees, that is what it feels like as you step outside today across parts of the midwest, davenport into chicago and springfield. so this is the feels like temperature that includes the air temperature and humidity and this is why authorities are so

cnn's derek van dam he's watching this for us. the situation there now and is there any relief? i mean, they need some help to put these fires out. >> reporter: kate, this is an all hands on deck situation. in fact, we've been told that the national guard has been enlisted to help with these wildfires as well. i mean, a dire situation, apocalyptic, that is the perfect adjective to describe what people are witnessing and seeing on the ground, specifically offer the western sections of the island of maui. i want to explain how hurricane dora's influence is helping fuel these stronger winds across the hawaiian islands. we have an area of high pressure to the north, there's hurricane dora. the pressure gradient between these two weather systems are actually putting that squeeze on the hawaiian islands and what that's doing is helping pick up the winds out of an easterly direction. so gusts, get this, have been over 80 miles per hour. that's equivalent to a category 1 atlantic hurricane, however, we can't say that the windser directly

cnn meteorologist derek van dam joins us now. t right? >> yeah, without a doubt, because we anticipate the earliest arrival of tropical storm force winds across the southern florida peninsula, roughly about 6:00 a.m. on tuesday. and as you head a little further north, north of tampa bay into the big bend area, we're talking about roughly 4 to 12 p.m. on tuesday. you don't want to be setting up your hurricane-proof shutters, for instance, in the middle of tropical storm force winds. so now is the time. it is your last full day for that opportunity to prepare your property. 65-mile-per-hour winds. it's basically splitting the difference across the yucatan channel. this is important. it is now moving north at 8 miles per hour, and that's actually increased in forward speed since the 5:00 p.m. eastern standard update. now, we do have a major hurricane in this forecast. that's important. if you're just waking up this morning, that wasn't explicitly in the forecast this morning, but now it is. we know the waters are extremely warm over

let's go to derek van dam. tell us, how strong is this system as it is traveling north?. look, this system is really off to the races. it is currently a strong tropical storm but likely and this is explicit language from the national hurricane center latest update issued about 15 minutes ago -- rather, 45 minutes ago, this storm expected to become a hurricane within the coming hours and then a major hurricane potentially by later tonight. and why do we care about this storm in the eastern pacific? it not only threatens portions of mexico but also the southwestern u.s. we have our first tropical storm watches across the baja california peninsula. the popular tourist destination of cabo san lucas under that watch. and this tropical storm is being directed north/northwest by two different systems. we have high pressure that is causing heat over the central u.s. and upper level low. and these will work together. this is not a typical type pattern so this will drive the storm system to more of a northerly direction basically running parallel with the baja california peninsula

derek van dam is tracking the path and we are seeing what's left behind, what is the flooding lookingward? >> this is the result of that 10 inches plus of rain, debris flows, mudslides, you saw it in stephanie's live shot a moment ago. they are so dangerous. zoom into what's some of the best video we have had come into cnn, look at the debris caught up in this. there are boulders, there are rocks, there are entire tree trunks, sometimes homes and vehicles can get swept away in this torrent of mud and debris that can travel over 30 to 40 miles per hour. we talk about burn scars quite often and they are so dangerous for the mountainous terrain of southern california. these burns, the forest fires can occur several years prior to this event, but when we see the burn scars lasting effect on the landscape, it's when we get these heavy rain events in the middle of summer when it's its driest when we have the biggest impacts. the forest canopy that normally absorbs the rain, the organic material on the surface of the earth is no longer there in a burn scar so it creates a layer that literall

cnn's derek van dam is joining us with more on this, how big of an impact is this having out at sea?it's certainly helping or aiding in the fueling of the flames and the tight pressure gradient. we'll get to those details in just a moment, but listening to the radio that we have with the hawaii lieutenant governor and this is all hands on deck and she's issuing an emergency proclamation on the big island near waimea bay. it's not just maui. it is also on the big island of that way where we're seeing these fires continue to spread. we have very erratic fire behavior. we've all seen the video. let's get to space and show you what it looks like. get some contextual perspective on this. you can see hot spots from space and this is the big island, that's maui and smoke and you can see the direction of the wind because it's pushing it in the southwesterly direction. the winds are coming from the east-northeast and it's all being fueled or helped fanned by what is hurricane dora to the south and west. so that's the high pressure to the north and hurricane dora. both are working together to

derek van dam is sweating it out at the pga tour championship. this is tough. look, this is tough.ng in golf, but they walk quickly and they're out there for hours. this is a really tough situation. >> yeah, you said it best. there is no escaping this heat, whether or not you're an athlete or a spectator. it doesn't matter. it's brutal. the air is thick. it's muggy. it currently feels like 105 degrees. we might get up to 106 to 107 at east lake specifically where the pga tour championship is taking place. get this, there's a heat advisory that lasts through the entire weekend all the way to the end of sunday. that takes us through the end of this championship tour. talking to the pga tour executive director, he says he doesn't want the players to focus on, well, getting overheated or dehydrated. he wants them to focus squarely on the $18 million purse that is on the cards here for the players, the 30 players gracing these links. whether or not they have the appropriate mitigation efforts, we walked around and we've seen a lot of precautionary measures in place from additional misti

let's get the latest on the forecast, derek van dam is joining us now. walk us through what they're looking at today. >> reporter: now they're going into more of a typical tradewind pattern. we don't have those 50, 60-mile-per-hour winds out of the northeast, but the problem here is they want rain. we need water to help douse some of the flames. the winds are coming at more of a northeasterly direction. up and over the mountain ranges, and the windward side will see the rain today, but on the leeward side, where luhina is located, unfortunately, we anticipate the forecast to stay dry. so any hot spots are going to have a bit of a difficulty actually starting to see any of that relief from the rainfall. as i advance this graphic, you'll see on and off again showers. there's some accumulation, especially in the higher elevations, but really on the eastern facing slopes of maui and into the island of hawaii. this is being exacerbated by the ongoing drought. new information to cnn, the drought monitor, we just got this within the past 30 minutes or so. this

cnn's meteorologist derek van dam is showing us how. >> reporter: it's virtually impossible to avoid or athlete. there are heat advisories for atlanta and the fofl course where this tournament is taking place. get this, heat indices could reach upwards to 109 degrees. that is dangerous heat, folks. there are several efforts around this course that have been set in place, something as simple as putting up cool towels at every tee for the players. there's also hydration station, misting stations, sunscreen stations to help the spectators and athletes. one piece of interesting technology i've never seen before is this cooling mitt. it has the ability to cool the internal core temperature of your body within a matter of seconds if you stick your hand in this piece of ee advice. a critical piece of technology shoulda person become overheated. the director of the tour championship wants the players to focus on the $18 million purse that's at play but not be dehigh traded. one of the georgia natives thought he would have an advantage growing up in this heat and humidity. we find out what he

let's get right to cnn meteorologist derek van dam who is watching this very, very closely. how destructive might the storm be, derek? >> yeah, using the words from the national hurricane center they're talking about rapid intensification, last time we saw that hurricane ian, we know how that played out. time to take it seriously. your last full day to prepare is today. we do expect that first arrival of tropical storm-force winds for early morning hours along the southern peninsula of florida. not just a florida storm and could impact the carolinas into southern georgia as well. this is crucial. starting to see that northerly turn and the storm is becoming more and more organized near the yucatan channel. the forecast track. you can see how it runs parallel with the gulf coast of florida so the west coast where we're concerned about, wednesday into thursday, and, yeah, that's a category 3, a major hurricane. we've seen this unfold before with, of course, being a game of miles, any track or deviation to the west or east has major implications for so many population centers bu
