ryan, what can you tell us? >> dan, good evening. i want to take you right to i want you to show you just on the other end of this field. that's the remaining part that the firefighters are trying to put out. you can still see some tall flames, tall flames burning on the other end of this yard. it's kind of like a grassy yard, almost in a way. and now the remaining crews are slowly trying to put it out. they have made some really good progress on this fire. no longer a threat to any structures in this area, but as you can see, it's still burning closer to the roadway here. we're right off of highway 580, kind of closer in the rural parts of east livermore. we did see some crews leave. they did dismiss some of them. they were on their way out of here, but some are still here trying to get a handle on it. you might be able to hear it, but it cannot be under understated. it is really, really windy out in this part of the valley. we know all weekend long that was a problem.

it still is a problem. right now i'm as close as i can probably get because that smoke is just kind of blowing towards this direction. it can only get so close without getting any sort of issues with the upcoming fire department. they did say about 110 acres did burn. it was spreading fast at one point, but they did make good progress on trying to get it contained. right now all that is left is just that remaining part on the edge of this field. you can still kind of see over here. this is the extent of it, about 110 acres that you can see here still burning, the smoke still rising. and this is just completely charred. we're not that far away from the corral fire. it's probably about just over this hill on the other end of this p-g-and-e's substation. that's where the burn scar from the fire over the weekend is very close to it. and as we know, windy conditions over the weekend caused that fire to spread very, very fast. and it's something very similar here. but right now, fire crews do have a handle on this, but we're going to keep monitoring right now you

can see the extent of the damage, not really close to any structures outside of the substation, but it looks as though that's kind of under uh. they've got a handle on that right right away. and so as this kind of progresses and as this unfolds, we'll keep you posted. but for now, this is the current scene here and just east of livermore. guys we'll send it back to you. okay. >> ryan, thanks very much. you can tell the wind is a real issue there. we're also keeping an eye on another small fire. this was in livermore sky seven over the scene just a short time ago to bring you these pictures. this is off cross road, and you can see that fire is burning on a hillside behind a row of trees and some structures there with that we say, good evening, i'm ama daetz and i'm dan ashley. thanks for joining us. we'll move now to the fire that has dominated today's news. >> then my niece came out of the room and said, you know what? i think the building behind our house is burning. and then i said, this is going to be kind of a bad yeah, it is a raging eight alarm inferno on a gusty day in redwood city is now contained, but danger remains.

>> we are going to have a 24 hour fire watch put into place. uh- to look for any, you know, flare ups and of course, our major concern is the scaffolding. we're looking at collapse aspect. >> and investigators are just beginning the work to figure out what caused the fire to spark at an affordable housing project under construction. >> now, most evacuated neighbors are back home tonight, but people all down the peninsula may be dealing with smoke as result. it's been about eight hours since the fire sparkedn middlefield road, just a few blocks from woodside, a neighboring streets had to be evacuated. >> we have team coverage on the fire's impact. both to people who live nearby as well as those miles away dealing with the smoke. we begin with abc seven news reporter zach fuentes. he is at the scene on middlefield road. zach >> yeah, i'm a middlefield road only opening up just about an hour ago. fire crews came here after reports at 1015. so that shows you how long this has been going on. the fire, though contained just after 3 p.m. this

afternoon. so 100 firefighters together fought this fire in an intense fight. i want to take you to that sky seven video from earlier today to show you this area, to give you an idea of the scope of this fire that tore through this affordable housing project. there are two buildings here and only one caught fire. it was a huge building though, and fire officials say it started at the north end of that building, and it was pushed by winds all the way to the other side. now, construction workers were on scene at the time. they tried to put the fire out with extinguishers. we're not successful, obviously, but thankfully there are no reports of injuries now. the affordable housing project has been nearly a decade in the making in terms of the planning of it, and construction got underway about a year ago. the building sits just behind fair oaks health care center, and that's a clinic. that clinic evacuated, as were homes that were also nearby here, the proximity to the homes, the state of the building, which didn't have a lot of safeguards in it yet. and of course, the winds out here have made this fire one that was very difficult for crews to fight. now, even with the fire contained, concerns still remain our major concern is the

scaffolding. >> we're looking at collapse aspect. so we want to make sure that the neighborhood is safe. so once we can mitigate that collapse effort, then it will be just looking at the hot spots and taking care of any issues that occur there. that would be of concern. >> hey, this is happening. crews believe that the fire started on the fifth floor of that building, possibly in the insulation. crews were working on insulation and sheetrock at the time of the fire starting cause investigators are on scene right now to determine that cause a specific cause that's going to be some time before they determine that. but of course, we'll continue to bring you updates. crews are going to remain on scene monitoring the hot spots, making sure that they don't escalate again, that no more flames catch, and of course that the surrounding area will remain safe. so they're going to be here for at least 24 hours again. middlefield road is now open. it had been closed all morning, all afternoon. so we have seen some progress. fire crews working very hard to contain this fire. and again, the cause to be determined right

now live in san mateo county. zach fuentes, abc seven news. >> all right, zach, thank you for that update. smoke from this fire led to an air quality advisory. this shot from sky seven shows you how far the smoke spread with today's winds. the bay area air quality management district was concerned about areas downwind of redwood city, like palo alto, mountain view, santa clara and san jose. and we will continue our live team coverage with abc seven news meteorologist sandhya patel. >> yeah, and sandhya, the smoke got so bad, there's really been a measurable impact on our air quality. >> yeah, it certainly was worse earlier when that fire was really going down and umma, i do want to show you the air quality now as we look at air now, you will notice that most areas from redwood city down the peninsula and that good category, there are a few spots down around san jose that are moderate. this is purple air and taking a look at theirs as well. you see some pockets of moderate air quality. so that air quality advisory is still up. although the conditions there are favorable. the winds have come down a bit. the relative humidity is elevated, the temperature is

down as well, 59% relative humidity right now. winds are still gusty in the surrounding areas. right now 31 in san mateo, you will notice gusty and other parts of the region as well. something that we are watching. numerous heat warnings, advisories and excessive heat watches are in effect across much of california. i'm going to be back with a closer look at the bay area, because we're in that as well. the heat wave begins tomorrow. i'll be back with those temperatures in the warnings coming up. ama all right, sandhya, thank youthe fire had a big impact in the neighborhood. the fair oaks communitytewas closed. child care and senior program participants were sent home. san mateo county fair oaks health center was evacuated. patients with appointments had to reschedulerfld community school, which is grades k through eight, was dismissed early because of the smoke. all after school programs were canceled. >> the fire caused significant delays to caltrain service. the tracks run right next to the site, as you can see from sky seven, and firefighters were running water hoses across the

tracks while the fire burned. some trains were being held at other stations. obviously, they couldn't run over the hoses. as the fire continued, caltrain set up a bus bridge with samtrans to move people around. when then it transitioned to hourly service, running trains from fourth and king in san francisco to redwood city and from diridon station to san jose up to menlo park. by 3 p.m, trains were able to pass through redwood city once again, although at slower than usual speeds >> the fire burned on middlefield road. people living nearby on calvin, pacific and dumbarton avenueserall told to evaate out 50 in total. an evacuation center was set up at the nearby veterans memorial senior center on madison avenue, and that is where we find our abc seven news reporter, lena howland. she continues our live team coverage with a look at what neighbors had to deal with today. lena >> dan and umma. just minutes ago, the san mateo county sheriff's office decided to close the evacuation center set up here at the veterans memorial

senior center in redwood city. they say that most evacuees are now able to get back inside of their homes, so they decided to close this evacuation center at 6:00 earlier today. this video of flames shooting from the construction project, taken from blocks away, was shot by a body shop off of middlefield road in redwood city just before 11:00. folks living nearby the fire on pacific and calvin were told to evacuate immediately. those evacuations were quickly extended to include folks living on dumbarton avenue from the train tracks to middlefield road. one evacuee told us the flames were so close to his home, he had just minutes to grab his mom, grab his dogs and get out, he said. he took matters into his own hands when he realized just how close the flames were. >> so what i started doing is i grabbed the hose, put some water on the garage, you know, just trying to make me feel good, i guess, you know, because there was nothing i was going to do because the fire was starting to spark up, you know, very much.

and it was the fire was starting to get very big. >> homeowners were not the only ones evacuated. garfield community school in menlo park also decided to close early because of the fire. parents at the k through eight school were told to pick up their kids as soon as possible because of smoke concerns in the area. now, the veterans memorial senior center told us that they did have two families stop by to check in, but they have since gone home for the day. again, this evacuation center closed their doors at 6:00 this evening. live in redwood city. lena howland abc seven news. >> all right, lena, thanks very much. the building that burned was an affordable housing project that's been in the works for a decade. called middlefield junction. it was designed to have 180 units plus a child care center. construction started last summer and was supposed to finish next year. san mateo county supervisor warren slocum spoke with us about it during our live streamed coverage

earlier today. >> it's just unfortunate and it's heartbreaking that the building is probably a total loss at this point. we've been working on this for ten years and it's a travesty because in california, affordable housing is so difficult to get built. it takes so long. and the primary problem is the financing of those developments. and this was a unique development in that it had one, two and three bedroom units. three bedrooms is pretty unusual. and so families were going to get to enjoy this new building. and those three bedroom units, uh- childcare and community reading room, community meeting rooms. so all that is gone now, as i say, i hate to keep saying it, but it's just a tragedy. >> yeah, it certainly is. let's give you a look at this fire by the numbers 1015. >> that's the time it started. fire went to eight alarms, 100 construction workers safely evacuated about 50 people in the

neighborhood had to be evacuated. zero injuries. thankfully, a big concern was the wind and the embers that were blowing around. just take a look at this video. you can see why firefighters were so concerned this video was shot on pacific avenue, one of the streets that was evacuated. embers flew as far as a couple miles away. menlo park's fire chief talked about how this made the firefight unique. >> i mean, what we were dealing with here, it's very interesting . typically on a on a large structure fire, we're not dealing with structure protection in the neighborhoods next door, but it's it reminds us a little bit of fire season and wildland fires. the embers, whether they're from insulation or from vegetation, uh- really work just the same. and so here we are in the middle of a urban suburban area, dealing with what we saw yesterday in san joaquin valley is, yeah, a fire spread through ember embers and winds. so those are obviously our two biggest threats right now. >> this is the fire. he's talking about the corral fire evacuation warnings for the area

have just been lifted and roads are being reopened. it burned more than 14,000 acres near tracy. the flames destroyed a home and hurt two firefighters. one is now out of the hospital. >> coming up next, new details on the mother and daughter injured at a walnut creek farmers market over the weekend. >> plus delays on muni not with busses but with bus stop signs. we look into why? because this is about building a better bay area

of dry age-related macular degeneration, can irreversibly damage your vision. it can progress faster than you think. when ga threatens your eyes, take a stand. slow ga with syfovre. syfovre is an eye injection that was proven to slow damaging lesion growth over 2 years with increasing effect over time. it's the only fda-approved treatment to slow ga in as few as 6 doses per year.

don't take syfovre if you have an infection, or active swelling in or around your eye that may include pain and redness. syfovre can cause serious side effects, such as eye infection and retinal detachments, severe inflammation of vessels in the retina which may result in severe vision loss, wet amd, eye inflammation, and an increase in eye pressure. most common side effects are eye discomfort, wet amd, small specks floating in vision, and blood in the white of the eye. tell your doctor right away if you have any side effects. every moment counts—act now to slow ga with syfovre. ask your retina specialist about syfovre. if right now says a fire near

patterson pass road is 50% contained, start at about 415 today and spread fast through the grass because of the winds pushing it. alameda county fire says it's burned 110 acres and is no longer threatening any buildings, so that's all encouraging. take a look at sky seven. in the first hour of this fire. you can see it burning right under those transmission lines. alameda county fire says they don't see any sign of those power lines coming down in the fire area. we do not yet know how this fire started, but of course it was hot and the winds were fanning it. it's burning close to the corral. fire outside tracy, though firefighters say they do not think these fires are connected in any way. and abc seven news reporter ryan curry, before going to that fire near tracy, put together this report about the efforts to reduce fire risk as we head into the summer months. >> on the heels of california's first major wildfire of the season. evacuees are now returning home to devastation.

>> it was a beautiful house, had a nice walkway up to the front of it, you know, the bedrooms were out towards the front. >> the corral fire is burning near tracy, spreading to more than 14,000 acres. it exploded in size after sparking on saturday, injuring two firefighters and triggering mandatory evacuations. the wind event that happened saturday night, was pushing, you know, sustained winds in the high 30s, in the low 40s, which made that fire move really quickly and made it very difficult to control. p-g-and-e's is now looking at fresh data from over the weekend. meteorologist scott purdy shows me this interactive map. the moment the fire started, it took the first fire guard perimeter that started and ran a simulation from there. >> and you can then see in time as we animate through the time steps where we were, you know, an hour from there, two hours from there. >> that data is quickly shared to crews like this one. their job is to preserve power lines during a fire.

>> our primary focus is to get out ahead of wildland fires and protect p-g-and-e's assets, mostly the wooden power poles. and we put long-term retardant on it. the same thing that comes out of the aircraft inside the hazard center. >> scott stringfellow shows me their map looking at wind speeds. one thing that i noticed looking over here, right in that area, it's a little higher than the rest of it. what did that look like over the weekend? >> yeah, it looked very it looked very similar. >> despite the strong wind, p-g-and-e's did not issue a public safety power shut off. sternfeld says it needs to be an unusual wind event for that to happen. and he says this weekend's conditions didn't fit that category. >> sperm is a measure of last resort, so it's not that first tool that we're going to take out of our tool toolbox. and so we typically look for an exceptional wind event, something that's atypical of like a normal pattern, like a sea breeze. >> ryan curry abc seven news man. >> and those winds have just been howling. yeah they have. >> and that's fanning these flames. and it's about to get really hot the next couple of

days. meteorologist sandhya patel is here with a forecast. >> yeah temperatures are going to soar that's for sure. dan. and especially away from the coastline. so we do have some warnings and advisories to talk about. and then we'll talk about those temperatures area shaded in orange all going under a heat advisory 8:00 tomorrow morning until midnight thursday. solano county under an excessive heat warning 11 a.m. tomorrow until 8 p.m. thursday. there is going to be a significant increase in the risk of heat illnesses. now, when you take a look at the heat risk map here, you will notice it's moderate to major for some inland areas shaded in the oranges and the reds right along the coastline. the yellows is just a minor heat risk. so just keep in mind, though, that this is the first heat wave of the season. it's going to be taxing on your body, so you'll want to definitely take precautions. high pressure is going to build in rapidly and that's what's going to bring us the heat. today we had a cold front coming through and that brought us a little bit of drizzle earlier this morning. i still have a lot

of cloud cover around as we look at live doppler seven right now, you can see some of that cloud cover, but we've been seeing a little more sun out there as well from our mount tam cam. it is certainly been a shaky view. low 60s from san francisco to oakland to hayward, 64 degrees. it is 74. in san jose, today's high temperatures, by the way, were in the 50s to 80s range. i hope you enjoyed it because things are really going to change from our emeryville camera. you can still see some of the low clouds that are around 76 in santa rosa. it is 61 in petaluma in the mid 70s. fairfield, concord, livermore, you're at 69 degrees. and from our exploratorium camera high clouds are filtering the sun. tomorrow the heat wave starts. fire danger will remain. high temperatures will soar, bay and inland records are certainly possible. and friday relief will arrive. for those of you who do not like the hot weather now, it's not going to be hot everywhere. you'll see that here in just a moment. so we start out with tomorrow morning in the 50s and 60s as we head into noontime. already warming away from the coast into the 80s and

90s. these will be our hot spots as we go into the afternoon hours. you start to notice some triple digits showing up along the coastline in the 60s, though, and then it's going to be slow cooling away from the beaches in the evening. still, in the 80s and the 90s. so your morning temperatures will begin in the 50s and 60s, mainly clear skies. there may be a few patches of fog lingering from today and then tomorrow afternoon, temperatures soaring well above average in the south bay. 92 degrees in gilroy, 91 in san jose on the peninsula, you're looking at upper 80s from san mateo to redwood city. 69 in pacifica, downtown san francisco, 78 degrees north bay. temperatures upper 90s from santa rosa to calistoga. 90 in san rafael, 96 vallejo in the east bay, mid 80s oakland berkeley 88, in castro valley. head inland and it's definitely going to be sizzling. 100 in fairfield. in brentwood, 97 in concord and in livermore. your accuweather seven day forecast triple digits the next couple of days. inland 60s coast side. the

heat eases as we head towards the end of the workweek, and you definitely get relief by friday when you drop down to the 80s. we'll keep you in that sort of range for the weekend. ama and dan okay. >> yeah, thanks, andy. >> well, we are four years past the pandemic. >> can you believe that? but here is a familiar face. why doctor fauci is back in washington, a super thin, flexible patch with maximum otc strength lidocaine that contours to the body to relieve pain right where it hurts. and did we mention, it really, really sticks? salonpas, it's good medicine. a slow network is no network for business. and did that's why morereally, choose comcast business. and now, we're introducing ultimate speed for business —our fastest plans yet. we're up to 12 times faster than verizon, at&t, and t-mobile.

to a mixed finish today following a report that u.s. manufacturing shrank in may. companies whose profits are most closely tied to the strength of the economy suffered the worst losses. the dow was down 115 points, closing at 38,571. the nasdaq gained 93. the s&p 500 picked up nearly six points. a jury of six women and six men is scheduled to hear opening arguments tomorrow in hunter biden's gun trial. president joe biden's son is on trial in delaware on three felony charges related to his efforts to obtain a gun in 2018, while allegedly addicted to drugs. the younger biden spent the first day of his trial taking notes, reading documents and often turning to catch a glimpse of the friends and family there, including first lady jill biden. he pleaded not guilty last october. if convicted, hunter biden faces up to 25 years in prison and a $750,000 fine. >> a combative hearing on capitol hill today when the man

who was the face of the federal government's response during the pandemic testified before house lawmakers. former director of the national institute of allergy and infectious disease doctor anthony fauci, answered questions about the u.s. response during the pandemic and the origins of the virus. he testified voluntarily, insisting he has nothing to hide. >> so you said about 4 or 5 things, congressman, that were just not true. >> well, we have emails to prove it. >> well, you don't 30 minutes of committee time during this time, democrats sought to defend fauci, acknowledging mistakes were made but calling the gop led investigations a wild goose chase. >> the committee chair says the focus of the hearing was to learn lessons and better prepare for the future. >> coming up next, the gap between plans and reality when it comes to new muni bus stop signs in san francisco overpriced and pointless, really . >> we're talking damages, delays, and nearly a decade of

are our for you. firefighters are getting a good handle on the fire burning near altamont pass. alameda county fire says it's burned 110 acres since it started. a little more than two hours ago now. this is near patterson pass road, not far from interstate 580. containment is up to 50. it's warm and it's windy out there. firefighters say there is no longer any threat to buildings, so that's encouraging. patterson pass road is still closed. this is an extremely busy night for firefighters in alameda county dealing with three fires, all starting within an hour and a half of each other. >> we're also keeping an eye on another small fire, this one off of cross road in livermore. alameda county fire says about ten acres have burned. power lines are also down. today's big breaking news was the eight alarm fire at an affordable housing construction site in redwood city. fire investigators are trying to figure out how this started. more than 100 firefighters fought to keep the flames from spreading to another building.

>> now their job was more difficult. today just from the nature of that construction site. we watched as huge pieces of scaffolding collapsed in the heat from the flames. firefighters say the buildings were not far enough along to add fireproofing features that would have perhaps slowed the spread. >> the big, the big challenge is initially are, you know, there's no fire walls in there. they haven't been constructed yet. so it's just a tinderbox and the fire spreads pretty quickly. >> firefighters evacuated some homes in the neighborhood, most of those evacuations are lifted tonight. an air quality advisory issued because of the smoke and wind has also been lifted. >> all right. turning to our work to build a better bay area, san francisco's muni says their goal, or its goal, has always been to improve the experience for customers. so whatever happened to those muni bus stop signs, right? abc seven news reporter liam melendez has been looking into that and found nothing but delays, delays and land delays. yeah, well, we hear that a lot of these agencies say or blame it on these delays on

the pandemic. >> and we're here to say yes and no, because when you start a project nine years ago and it has yet to be completed, that's when we hold sfmta accountable. now, viewers remembered when the project was first announced in 2015 and asked us for updates. and here's what we found. maybe you have seen them, or maybe not . >> what's at the top of it? is it intrusive? it looks like something that's monitoring you. >> i'm assuming it's something showing bus lines and routes for this area. >> it is pretty much what you see. a long pole with solar lighting at the top and signs indicating the bus route. muni wants to make sure you know which bus you're hopping on on during the day or night. so you can look at this sign saying that, oh, this is where i catch my bus. these muni bus stop signs began going up in 2015. the idea was to have 3600 signs around the city, but by 2018,

there were only 22 of them in operation. clear channel was expected to pay for all of them through an advertising deal with the san francisco municipal transportation agency. the sfmta. but now clear channel is out of the picture and didn't return our calls. as of today, the sfmta tells us of the 3600 that are expected to make life easier for muni customers, only 300 have been installed. yep, you heard that right. nine years after they started, less than 10% of the project has been completed. sfmta told us both the pandemic and staffing levels impacted the project. we're now staffed up and have continued with the installation after clear channel bailed out, the sfmta had to rely on san francisco motorists to pay for the new poles. they are now using funds from proposition aa, approved by voters in 2010. the measure added $10 to the yearly

vehicle registration fees. that extra fee generates about $5 million a year. prop a monies are designated for local street repairs and projects that make public transportation more reliable. to complete the project, sfmta says it will need nearly $2.5 million. sfmta has already received the entire amount overpriced and pointless. really, the sfmta doesn't think they're pointless. but here's what we found as time goes by and it has. a few of the signs have been vandalized, like this one located at mission and 16th. the bus route signs for the number 14 line have disappeared. gone. here's an sfmta photo of the installation of one of the signs near the tenderloin district. but we couldn't find it because the entire pole had been removed. and here's what was left. and here's another damaged one along mission

street, barely attached to the pole. after some of the screws % raise an important question. by the time sfmta finishes installing all 3600 poles, will muni even be able to rely on the system designed to make the ridership experience more reliable? will they be obsolete? now? we will say that being a transit agency in a city like san francisco has its share of challenges. now take the glass panels at some of the bus stops, for example. many of them have been vandalized and muni has spent upwards of $800,000 to replace them. now, no more nice glass panels for this city. they will be replaced with metal bars or in some cases, plexiglas. and i've already seen that one near my neighborhood. yeah, plex. i had to bang on and kind of tap it and see, oh yeah, it's plexiglas. but yeah. frustrating. yeah, frustrating. i just don't see how people

vandalize things like that when it's our city over and over again. >> correct? yeah. all right. thanks, liane. >> well, 70 people face trespassing charges for a protest today at the lobby of san francisco's israeli consulate. police put up barricades, and we saw officers removing several people from the building. officers say they arrested those who refused to vacate the premises. they were cited and released. consulate spokespeople say they were thankful to police for their rapid response. new details tonight about the hit and run driver accused of injuring a mother and daughter who were setting up at a farmers market. it happened early yesterday morning in walnut creek. tonight both the mother and the daughter are in critical condition. here's abc seven news reporter leslie brinkley. >> there is still orange paint on locust street in downtown walnut creek, marking the places where shoes landed on impact from the two women badly injured in a hit and run accident around 5:15 a.m. before the weekly sunday farmers market opened. it's unclear if road closure

signs have been put in place yet by the contra costa certified market association. >> a black suv ran into one of the vendors as they were setting up, hitting a mother and daughter, and both sustained critical injuries. they were transported to john muir hospital for their injuries. >> officers then located what they believe to be the suspect's vehicle on buskirk avenue. >> one of our officers did locate a vehicle going northbound. with damage to the vehicle, that officer made a traffic stop, and field sobriety tests were given to the driver, and he was subsequently arrested for dui and hit and run. >> police identified the man wearing the security jacket as a 33 year old resident of vallejo, who is now in jail in martinez. a passenger in his car was not arrested. vendors and business owners along locust street were shocked. >> it was bad. and it's just, i

hope that it doesn't impact the farmers market as far as whether it stays or goes. the foot traffic, the vibe. awesome. it gets a lot of activity. >> as much as people love the farmers market, others express concerns off camera about what they see as increasing alcohol consumption and dui in downtown. the director of the contra costa certified market association would not comment on signage, but said there is no go fund me set up yet. the family is asking for prayers in walnut creek. i'm leslie brinkley. abc seven news. >> the san mateo county sheriff's office just moved into its brand new headquarters. for more than 60 years, it's been based out of the hall of justice in downtown redwood city. now it's right across the street. the new state of the art headquarters is on the site of the old mcguire jail. it's connected to the current jail and has an elevated walkway to bring inmates directly from the courthouse to the jail. >> coming up here, an invisible

threat from wildfires. what stanford researchers have uncovered about the long term impact and what it means for california's future

of months at sea. the 418 foot munro pulled up to coast guard island this morning. crew members, as you saw lining the side of the cutter to see their families. as you can imagine, there were lots of hugs, smiles and tears as the men and women of the munro reunited with their family members. >> words cannot describe it. it's been 124 very long days and , you know, to look what looked like three adults and a little boy walking up here. it's great to be here. it's so great to be home. >> the coast guard says the munro's mission was a major success, confiscating nearly 34,000 pounds of cocaine with an estimated value of $468 million. they also supported the crackdown on illegal fishing operations off the coast of peru. >> good work and welcome home. well, as california struggles with the ongoing effects of wildfire, researchers at stanford are working to

understand long term threats that may affect neighbors, firefighters and actually, the forest itself. >> abc seven news meteorologist drew tuma has more on the gray, smoky skies can be seen for hundreds of miles, but now researchers are on the trail of wildfire threats that are invisible to the naked eye, the result of intense heat from wildfires burning longer and hotter. >> when we start getting really severe fires, we see a transformation where the really, really intense fires leave these lasting impacts on the soil. >> scott findorff is leading a multiyear study with stanford's d'aw school of sustainability. they examined soils and forest areas that have been slow to recover from recent wildfires in the sierra and elsewhere. although early research has pointed to cycles of drought, pfender and his colleagues identify high toxic concentrations of chemicals in the soil, which could also be slowing regrowth. >> it really shows that it isn't just drought, that it really is a consequence of a number of

toxins being produced that end up altering the soil, along with physical changes that then retard ecosystem recovery. >> he believes the chemical changes are driven by the intense heat from recent fires. in an earlier study, the team found the process can change certain naturally occurring metals into a toxic compound called chromium six, while evidence of those chemical changes is building, the team is working on another question, which is urgent just how far do those toxic particles travel? he says the results are still preliminary, but concerning as an example, the canadian wildfires were bringing smoke down into new york, into washington dc and throughout the eastern seaboard. >> our current modeling shows that those would all have been bringing these same toxic metals into those populations a thousand miles or more away, stanford researcher sharon raja studies breathing and allergies and effect on the immune system. >> she's concerned about the unknown levels of exposure. >> the total amount is what

we're worried about, absorbing, whether that's through the skin or through our respiratory tract, through our eyes. right, or ingesting it. so these are all important considerations. >> professor bendorf says his team will be working through the current wildfire season, trying to develop threat models based on everything from geology to a fire's duration to wind conditions. all in an effort to keep firefighters and others safer from toxic exposure. in an era of climate change and increasingly intense wildfires at stanford, drew tuma abc seven news and researchers say another key concern moving forward will be the safety of drinking water. >> yeah, and they're hoping to learn more about the effects of runoff from contaminate soils. >> coming up next, a look at the heat wave that's about to hit the bay area so don't just play. stay... at northern california's premier casino resort.

nine. >> what a career he's had. oh, yeah. all right. >> i'd like to buy an e and an a, and the word is heat. >> i wondered where that was going if my brain wasn't putting it together. sandhya. yeah >> you're going to have the heat, that's for sure. especially away from the coast tomorrow. ama and dan. let's take a look at live doppler seven right now. still some lingering clouds. those clouds are going to be long gone tomorrow. and the heat is on upper 90s to low 100 for our hottest spots inland. 100 in fairfield, 99 in antioch. so it's definitely going to be hot. at least we have the ac there. 78 in the city, 86, oakland 91, san jose 90. in san rafael, 98 in santa rosa. but look at half moon bay, 65 degrees. now wednesday we're going to notice those triple digits again in our inland communities. just a friendly reminder. the heat wave begins tomorrow. drink plenty of fluids. wear lightweight clothing. try to take frequent breaks in the shade, and know the signs of heat. illnesses never leave people and pets inside the vehicle. you know it gets a lot hotter inside. and as you look at the accuweather seven day forecast, you will

notice the two hottest days will be tomorrow and wednesday with triple digits inland 60s coast side. the heat does uays thursday and everyone feels it by friday with 50s to 80 over the weekend it will be nicer. dan and ella okay thanks to that. yeah. >> all right. sportscaster larry beals here. giants not so great. >> you noticed uh- hard to miss with all the yankee fans screaming in joy last night. the giants they just got swept by the yankees. this is not going to help going forward yet another injury for pitcher blake snell got the giants were counting on at the top of their rotation. the latest on snell. when we

my name is david. i've been a pharmacist for 44 years. when i have customers come in and ask for something for memory, i recommend prevagen. number one, because it's safe and effective. does not require a prescription. and i've been taking it quite a while myself and i know it works. and i love it when the customers come back in and tell me, "david, that really works so good for me."

makes my day. prevagen. at stores everywhere without a prescription.

of the giants. they signed snell for over $30 million a year, but he missed all of spring training. just wasn't ready. and he hasn't pitched very well now. hurt again aggravating the adductor injury. basically it's a groin pull. so he's back on the injured list once again. women's college world series star sanford taking on texas loser leaves town nigel kennedy, an ace for stanford showing off the glove diving catch off the bunt attempt and then the throw. are you kidding me? so kennedy held top ranked texas scoreless until the final inning. ashton maloney bunts runners at second and third. lead runner alyssa washington caught in the rundown. they got her. they got her. they don't have her. she

slides in safely just underneath the tag. incredible slide right there. and that was the one and only run the winning run one nothing texas the final stanford is eliminated vikings receiver justin jefferson just became the highest paid non-quarterback in the nfl. four years $140 million. the question now is how does that impact the 40 niners contract situation with brandon aiyuk? he wants an extension. jefferson is regarded as the best receiver in the league. set an nfl record for most receiving yards in the first three seasons of a career, then eclipsed a thousand yards last year despite missing seven games. and vikings had all sorts of quarterback issues. so his deal works out to an average of $35 million a year. that's a lot more than brandon aiyuk figures to get. but a high tide raises all boats. and you can bet that's what seahawks agents are telling the 40 niners more niner news. they found a solid tight end to backup george kittle. logan thomas expected to sign with the niners ahead of mandatory minicamp, which begins tomorrow. thomas spent the past four

seasons with the commanders. 55 catches and four touchdowns. last year, actually began his nfl career as a quarterback. so you know how kyle shanahan likes the tricky stuff. maybe we'll see that with logan thomas. preparations are underway for the american century championship. it takes place next month in lake tahoe. last year, of course, steph curry won the event, but the champ is not returning to defend his crown because steph is going to be getting ready to play for team usa in the paris olympics. 40 niners legend steve young is not so confident he can fill the void. >> this really golfers that can go out and compete and go after each other. then there's guys like me that are just trying to survive, right? and that's just trying to like, you know, not completely embarrass yourself. but the feeling is the competitive nature of it, putting your name up on the board alone and then having a score, players can look like they're having a good time. oh, this is easy going. no one's no one's easy going underneath it. we're grinding, trying to make sure we don't embarrass ourselves. >> everybody gets nervous. stunning news today. really sad

with the passing of former 40 niners and cowboys offensive lineman larry allen. it's six three, 325 pounds. allen was a nightmare for opposing defenses. second round pick out of sonoma state in 1994, it quickly became one of the best in the nfl. hall of famer. in 2013, allen played most of his 14 seasons for dallas. the last two years, though, were with the niners. his strength was off the charts. this guy bench pressed 700 pounds. the 52 year old allen was vacationing with family in mexico. no word on the cause of his passing. sports on abc seven sponsored by smart and final. i used to see larry allen all the time at the supermarket. used to wear these oversize kobe bryant jerseys. i remember walking up to his gentle giant, thankfully, and i said, you want to come on tv? he's like, no, no real crazy getaway little person, thankfully. >> all right. and thank you for joining us. i'm ama daetz and i'm dan ashley for sandhya patel. >> larry, bill, all of us. we appreciate your time. we'll see
