. >>> for more, let's bring in meteorologist derek van dam. derek, unfortunately, it is not over yet. >> yeah, a difficult situation looks like it may get harder to deal with, with more flooding on the way, at least the potential. certainly heavy rain coming. and you know what, after the rain subsides, then the heat starts to settle in across these areas as well. i'll highlight that in this update. national weather service has issued a flood watch across the areas hardest hit by the recent flooding. current radar all generally quiet aside from a few light showers. there is heavier thunderstorms moving through the louisville region at the moment, but there is more precipitation on the way as a stalled out frontal boundary kind of settles in, meanders across the region and it will send pulses of moisture across the tennessee river valley. so this particular area highlighted in the shade of yellow, this is the weather prediction's flash flood threat, a slight risk for today through monday morning for these locations. not just southern kentucky, bu

joining us now is derek van dam. heavy rain and lightning as well. >> yeah, looks like mother nature could be creating its own fireworks this weekend depending on where you are located that is of course. we have a lot to cover here, but it is an important weekend because so many people are traveling, medillions of americs are back to the skies and roads across the midwest and great lakes, no problems today, but i do believe that changes will be changing here especially across the greater chicago area. and we'll get into the details of that in a moment. but we have had a busy past 24 hours. yesterday we actually saw over 100 reports of wind and high wind gusts as well as wind damage across the east coast. 31 reports of hail damage. today's severe weather threats just a marginal risk across the carolinas with a departing tropical system. greatest severe weather threat today, across central montana and across the northern plains as well, damaging winds and large hail. monday the big day, july 6th, independence holiday h

cnn meteorologist derek van dam joins us now. happy july 4th to you.ey look like for most americans on this day? >> rosemary, timing is everything. with the independence day forecast, especially for people who want to go out and enjoy fireworks late in the evening tonight, so heads up, chicago, des moines, minneapolis, those are the areas that have the potential for strong to severe thunderstorms today's. across the southeast it's more of a scattered variety. places like atlanta, maybe a few pop-up showers and thunderstorms even though downtown atlanta had their fireworks sunday evening. downtown northeast, beautiful in boston. let's get down to the severe weather forecast because this is a potential. we're really keeping a close eye on this. the storm center in their 2:00 a.m. update extended the veer weather threat into michigan, my hometown, included in that. chicago to minneapolis, that's an area we're looking out for the potential of strong straight line winds. also severe weather across montana and into the northern plains as well. look at how th

now to derek van dam. let's pivot from europe to here in the u.s. where millions of americans are going to be under those heat advisories. how hot is it going to get? >> we're packing about the entire northern hemisphere under the heat vein. a vein. this aen streetly hot setup across europe. and i'm showing you this in farenheit. you can see in the iberian peninsula, 110 degrees. and this is direct heat off of north africa. the heat will stick with us for the next foreseeable futures. temperatures in rome will be in the upper 30s, many locations will top 40 degrees across spain. and in the united states of america, now as the moments go on literally within the past ten minutes, we've seen more locations fill in on this map where the national weather service has indicated that the heat is going to be so excessive that they have to put alerts out to the general public and now we have 90 million americans just the latest number here that are encompassed by the weather alerts, the heat alerts stretching from the east coast through the midsection to the

. >> all right, let's bring in cnn meteorologist derek van dam. derek, i'm thinking of the search and rescue efforts and that window of decent weather is closing fast, right? >> yeah, without a doubt. regrettably we have some disturbing information now just new to us here at cnn, we read the latest updates from the weather prediction center, they update about 5:00 a.m. eastern standard time, and they have now included southeastern kentucky, the area that was hardest hit by the flooding in a moderate risk of flash flooding today through monday morning. that is a level three out of four. some of the wording they used in their description is very strong as well. i'll read it verbatim. they say it is going to become or it is looking likely that a favorable setup for very efficient rainfall is going to take place through today and overnight tonight and into monday morning. so the potential for flash flooding increasing across unfortunately southeastern sections of kentucky. let me show you the flood watches in place, anywhere you see the shading of gree

. >>> and let's bring in derek van dam. this is just devastating and we heard residents saying that it was the speed of the water it seems that took them by surprise. and it is not over yet, right? we're expecting more rain to fall. >> yeah, when you have nearly 200 millimeters of rain falling in 12 hours or roughly 9 inches, that is a significant amount of precipitation in a short period of time. unfortunately there is more precipitation on the way. not as heavy as what we've experienced, but you can imagine adding additional water to this situation is only going to make matters worse. just look at this video, this is an elementary school that is submerged by the water. you can imagine why. the governor says some of the residents here will take not months but years to recover from this devastating flood. and if you look at the radar sfimt estimated rainfall, it is southeastern kentucky that has been hit the hardest with the most amount of rain. these are some of the rainfall totals. over 10 inches in buck horn lake, that i

. >>> for a look at what's in store weather-wise this holiday weekend, cnn meteorologist derek van dams now. lots going on. unfortunately, most of it not great for travelers, whether you're driving or flying. >> yeah, you know, people looking to get their own fireworks could get from it mother nature, actually. because lightning will fill the skies for many locations across the u.s. just like it did along the eastern seaboard yesterday. we have had over 100 reports of wind damage and even 31 reports of large hail across the eastern seaboard. this is all associated with a few different thunderstorm lines that came through. some of the most populated areas of the eastern seaboard of the u.s. today's threats marginal across the carolinas. then a greater risk of severe storms across the upper plains and into montana where we have an enhanced risk of damaging winds and large hail. as we fast forward into monday, of course, the fourth of july, the large independence day celebrations across the united states. these areas here actually have a slight risk of severe weather. notice this does inc

for more on this, let's bring in on meteorologist derek van dam.f my favorite areas in california, this oak fire is really raging out of control. what more can you tell us? >> people in and around the yosemite area, south lake tahoe should expect to see thick smoke and haze coming up over the next 24 to 48 hours as the fire continues to burn, continues to get larger. this is our near surface smoke forecast, you see purple and red indicating the thickest of smoke that will meander across that area. here is one of the dozens of structures that have been impacted by the oak fire that still rages out of control. this is on the backdrop of the record-setting heat across the u.s., over 20 potential record highs today. many of them focused along the eastern seaboard. so let's get right to it. over 90 million americans much of our populated area under heat advisories or excessive heat warnings. 100 degrees in philadelphia, breaking a record high temperature today, matching that in the boston area as well. heads up with all this heat, potential for severe w

quite the climate emergency if you ask me. >> derek van dam, thank you so much. want to go to our barbie nieto who is in rome where temperatures are expected to hit 99 fahrenheit in a few hours. barbie, first on the heat, you're up there on the roof. you must be feeling it too. how are folks being affected across the country there? >> yeah, it's oppressive. and it's been so hot for so long that you're just, it's a depressing factor. people are doing everything they can to try to stay inside, to go to places that are air conditioned. as you mentioned, air conditioning is not that common in italy or much of southern europe. it's expensive to run it. but it's not cooling off at night either. that's what makes this heatwave seem so different than other ones. it used to be that you could cool off at night. that doesn't seem to be the case this time around. it is hot. people are staying inside. people are avoiding the activities they normally would be doing in the summer. the beaches are full, but not to the extent you've seen before because it's just too hot, even to

. >> more on this extreme weather i'm joined by cnn meteorologist derek van dam.t we just heard there, unfortunately sounds like folks aren't out of the woods yet. more rain on the way. >> yeah. so we have a brief reprieve. the next 24 hours should stay dry over the hardest-hit areas, perry county, for instance, over eastern sections of kentucky. sunday into monday, as you heard the governor talk about a moment ago, that will allow for a resurgence of moisture, more showers and more thunderstorms over the areas hardest hit. look at this forecast and radar, this is going forward into the future. saturday, you notice it's dry through the course of the day today. over eastern kentucky. however, look into sunday, starts to really fill in there across that region. the potential for more showers and thunderstorms and the forecast calls for an additional 1 to 3 inches over these areas. keep in mind, the ground here extremely saturated. we still have some of the major rivers cresting the kentucky river as some of those smaller streams and creek beds start to flow into tho

reach almost 97 farenheit, 36 degrees celsius in just a few hours but we begin with meteorologist derek van dam it's not just europe dealing with the heat. seems the whole of the northern hemisphere is being baked. >> literally. i think that's the climate of urgency that we're all collectively facing from north america, europe to northeast asia and focus in on what's happening across the united states. just literally minute by minute i'm seeing the updates from the national weather service come in and the heat advisories expand, especially across the nation's mid section. memphis, you're included in the heat advisory. much of the east coast and portions of the west coast. this spans coast to coast over 80 million americans under some sort of heat advisory with heat -- excessive heat warnings inclusive of philadelphia. heat advisories from boston to new york. when you step outside, it will literally feel like 105 degrees today when you factor in the humidity. so ice, a precious commodity today across the nation's capital they try to keep their drinks cool, bodies cool, do whatever they can to be

let's get to meteorologist derek van dam. derek, nice to see you. happy 4th.hat's the latest on the storm front? >> i think i heard a collective sigh from our viewers this morning. they know when they hear bad weather, fourth of july extended holiday weekend, they know it's travel headache. it's thanks to this warm front here. the storms are trekking across the frontal boundary. right now currently located across western minnesota, and so this is going to impact minneapolis this morning and this afternoon into chicago. even some secondary thunderstorms that will form. storm prediction center has a slight risk of severe weather. mother nature might well be making its own fireworks display this evening across the windy city. do take care if you're traveling across this region. moving about, some of these storms could be accompanied by stronger winds in excess of 50 miles per hour. the severe weather threat travels to the mid-atlantic tomorrow when many people return home from their festivities this weekend. so the northeast clear today in terms of weather delays

. >> for more on all this extreme weather, i'm joined by cnn meteorologist derek van dam. let's build on what we just heard here. it sounds like those folks in kentucky aren't out of the woods yet. >> no. we have about a 24-hour window where we could dry out a little. but the rain gauges still at major flood stage. look at this forecast radar imag imagery. today, being saturday, will stay drive. pay attention to the top portion of the screen. as we work our way into sunday notice the showers and thunderstorms starting to pick up in intensity. saturday's outlook from the weather prediction center, just a marginal risk of flash flooding across the extreme eastern sections of kentucky into west virginia because of the ongoing river cresting taking place in some of the larger rivers. but as we go into sunday, that's n another story. even into virginia and the carolina, that is thanks to the st stalled out frontal boundary. we know that we've had back to back one and one thousand-year events. the likelihood is 0.4%. when it happens in two very close approximations, you wonder w

cnn meteorologist derek van dam has all of the details on this weekend holiday travel. where are the potential travel delays expected for the rest of the weekend? >> we got the chance of severe weather today across the east coast. some of the major metropolitan's most populated areas of the united states. that could potentially have a knock on or snowball effect in terms of aviation across the country. this is the area we'll ftarget for the potential for significant delays for low cloud ceilings and weather potential. this sounds like a bad joke. you start thinking of increased demand, staffing shortages and now weather problems. and you've got a recipe for disaster, at least. look at this. nearly 50 million americans with slight risk of severe storms today. large hail, damaging winds. that includes the nation's capital, philadelphia, the big apple, all the way to boston. those areas can be affected by storms this afternoon and evening. get fuel from the sunshine. and we start to clear things out on sunday. but not before the damage is done. right? here's our forecast w

. >> for more on all this extreme weather, i'm joined by cnn meteorologist derek van dam. we heard the governor say he's never seen anything like this. this is two separate 1,000-year flood events in the u.s. what does all this mean? >> having back to back one in 1,000-year events is extremely rare. we had st. louis earlier in the week and eastern kentucky just a couple days ago where exceptional amounts of rain fell in a short period of time. what exactly does one in 1,000-year event mean? it doesn't mean that every 1,000 years we'll see a flood of this magnitude. it is a statistical average that meaning that a .1% chance. a deck of cards, right? if we're referring to a 100-year flood, the cumulative risk over a 30-year period, the odds there about 26%. that's like pulling out any red heart from the deck of cards. a one in 500-yard flood is equivalent to the chances of you pulling out two red hearts out of that deck of cards. but a one in 1,000-year event, this flood, for example, or the two one in 1,000 year events is so rare, it's like pulling out a red diamond ace of s

let's bring in derek van dam. wow, i mean, that map says it all.ed. >> yeah, no the what we want to see. it is the middle of summer, but we'll have to take it. over 75 million americans will experience temperatures of 90 or above over the next week and bet there will be some records shattered. and i want to show you this because many of the plots are along the eastern sea board as to new york, philadelphia, boston, you have the potential to see some of those records broken. excessive heat alerts for over 80 million americans, heat warnings for the southwest and particularly along the east coast. these are just been hoisted by the national weather service. the heat index could be over 100 degrees in the big apple. if this temperature forecast verifies through the weekend, this could potentially be the longest streak of 90 plus degree weather in new york city since july of 2013 and it looks highly likely as temperatures will easily break the 90 degree mark through the weekend. triple digit heat st. louis to memphis, more of the same across the deep s

derek van dam has more details on that. >> that's right, max.illions will be traveling today through the course of this extended holiday weekend, myself included. many of us want to get a head start on our early weekend plans. and there is going to be some travel problems, travel concerns i should say, that being severe weather across the upper midwest and the potential for some flash flooding across the gulf coast states, monsoon natural moisture over the four corners. but today is your day to travel in the northeast. but things will change as we head into the weekend. look at what the national service has done, they have issued a flood watch in and around the houston area, this includes galveston, this is all thanks to what was a tropical disturbance just off the coast of texas. no longer monitoring this for tropical activity because it has moved on shore, but this storm system will bring plenty of gulf of mexico moisture and it will kind of resurge all of this rainfall potential into the area. we've had plenty of drought conditions across eas

joining me is cnn meteorologist derek van dam. what can they expect the rest of the day?> nothing fun about pushing your car through flooded streets, max. that particular area, that comes from arkansas and the central parts of the u.s. you can see over the next few days, pretty much rain-free the most part. the bulk of the thunderstorms today and the return to the office -- return to work, for instance, on tuesday after the fourth of july holiday, basically across the midwest and eventually stretching toward the east coast and the mid-atlantic. today chicago to minneapolis, you need to keep an eye to the sky. mother nature might be making its own fire works display to celebrate and cap off our independence weekend. you can see the thunderstorm chance probability across the northern great plains and into the midwest. all draped along this frontal bondery. thi -- boundary. this is going to produce straight line gusts, we could see winds in excess of 50, 60 miles an hour if they form. damaging winds, large hail a possibility. look at them form. chicago all the way to grand r

let's bring in cnn's meteorologist derek van dam.lenty of delays because of the bad weather i just mentioned and now a tropical storm? >> we have been monitoring this off the coast of south carolina. it had very suspicious characteristics of tropical development. sure enough, 5:00 a.m. eastern standard time the national hurricane center comes out with an update officially tropical storm colin has developed. that has to meet a certain set of criteria including some of the rotation in the radar which i'll show you in just one moment. 40 mile-per-hour winds with this particular system. it sits about 50 miles to the southwest of the myrtle beach area, considering this is the fourth of july weekend, lots of people hitting the beaches along the coastal carolinas. this is something you want to keep very close attention to because the potential for this to produce strong gusty winds and also localized flash floods. really confined to the coastal areas including wilmington. here is the official track from the national hurricane center, still

and i want to begin with derek van dam. a terrible picture across the u.s. are temperatures expected to rise again this weekend? >> yeah, it sounds like from what you're saying we're moving from europe to asia and now to north america with heat wives, this is starting to sound like a broken record. and to answer your question, yes, we will be shattering more records this weekend from today right through sunday for many of 9 most populated areas of the eastern sea board of the u.s. so you can see the potential high temperature records being broken over 50, and many plotted along the east coast, new york, boston, those areas. right now over 70 million americans under weather alerts. many located across the central u.s., the southwestern parts of the u.s. under excessive heat warnings and along the east coast. boston, hartford, new york, philadelphia, they have heat advisories in effect that meaning that the heat index as you step outside, this is what it will feel like on your skin, may reach 105 degrees. so the actual air temperature a little cooler, but stil
