Coming up, well talk about when we might get some relief in terms of that air quality and cooler temperatures in our forecast comes up in about 12 minutes from now. Poor air quality sticking around for at least another day. You can see the haze and probably smell the smoke in many parts of the bay area. This is video of the smoky air from our hd sky cameras. And a viewer from Redwood Shores sent us this video of ash falling onto the ground tonight. People in sensitive groups should be cautious. That includes seniors, children, and people with respiratory and health issues. If anybody does smell smoke, we do recommend that residents protect t avoiding exposure so that staying inside with your windows and doors closed. We also recommend putting your airconditioning on circulate if possible and also checking with your city and county for any cooling centers if it is too hot to stay indoors in your own home. Christina chu says relief may come thursday with onshore winds blowing in but that all depends on fire containment. The smoke so bad right now its prompting alerts from Law Enforcement agencies.

Janelle, rarely do we have fires like this on the peninsula. From burlingame to redwood city, woodside, palo alto, you can see that smoke coming from the mountains and the coast near pescadero.

Lets bring ian cull who joins us in pescadero with the latest. Ian, what are you seeing . Reporter raj, that latest includes some evacuations that were just sent out by santa cruz county, including big basin state park.

Weve seen a lot of emergency crews going southbound on highway 1. Overall 7,500 acres have burned. 1,200 structures are threatened and there is still zero containment.

More than 350 firefighters working to stop its spread. At least seven helicopters dousing the flames from above. San mateo sheriffs deputies went door to door. Were evacuating. Weve been here almost 50 years and weve never had to do it. Reporter Marianne Connor heard the evacuation notice from one of the helicopters in the Rural Community of loma mart tht has limited cell service. Well see what happens tonight and try to check on things. Hopefully our house will still be there. Reporter lisa was camping in butano state park. We were out hiking and when we came back, one of the other campers said, hey, you had to evacuate. It took us about an hour to pack everything up.

This appears a little too close for comfort. Reporter yeah, its getting pretty close. Be hennessey fire going from 2,500 acres at this time last night to 10,000 acres. Keep in mind that state resources are stretched thin. More than 500 firefighters up here but theyre no match for these flames. We have spent the night watching these firefighters stop the flames halfway up this mountain from taking a house. Look at this battle going on in napa county tonight. Fire crews staving off the flames head towards a hillside home. Embers showering down on the roof. Firefighters armed with hoses, apparently winning this battle. But not all battles have been won in the hennessey fire east of st. Helena. At least three structures leveled, 10,000 acres burned, zero containment with fires blazing across the state, crews with their backs against the wall. With the resources stretched thin across those fires, it does make it difficult to get some resources in and also air resources are stretched thin. Reporter we heard o firefighter describe his job in these words. It is hot, and everything is trying to kill you. Its hyper dynamic and ever evolving, super stressful. At the same time, its the best job in the world, and i love it. We lost one house, one of our cousins lost another house. Reporter this is one of the houses firefighters did save.

Deputy Alan Strickland filed a federal lawsuit against the raptors claiming the Team President was the aggressor and punched him in the face. The raptors are countersuing and gave us access to this body cam footage that shows it was the deputy that initially shoved the president twice and that strickland, the deputy, falsified the details of this altercation. The raptors sent us a statement tonight. It says in part, we believe this Video Evidence shows exactly that masai was not an aggressor but instead was the recipient of two very violent, unwarranted actions. As for that federal lawsuit from the deputy, it still remains before the courts. Okay. We want to check in with rob mayeda. We have poor air quality because of all the fires burning in the bay area. When can we see some of this blow out of here, rob . Were hoping by this time tomorrow night as we will be done with our excessive heat warning. Well begin to see signs of a stronger sea breeze, cooler temperatures and perhaps better air quality. For the moment were seeing troubling signs on the fire lines in terms of temperature, humidity, wind and what were able to see on radar. Lets show you the temperatures outside along the fire lines of the north bay. Youve got 80s and 90s outside still. Humidity levels in the 26 to 10 range. So that fires not laying down as they typically do with cooler temperatures and higher humidity. The fact that a remote radar can still spot the smoke plumes at this hour tells you that fire is very active. Its also letting us know where the embers and ash where thats falling into eastern napa county and solano county. Big impact on air quality out towards vacaville. Unhealthy air drifting into San Francisco and oakland from those fires burning in sonoma and marin. This is the fires here burning in the Santa Cruz Mountains, crossing the line from San Mateo County into santa cruz county. You can see the smoke is spilling over the lower peninsula. Redwood city, fremont, san jose, those red dots indicate unhealthy air for everyone. Thats even higher than the spare the air tlesh hohreshold. We could see localized very unhealthy air quality at times for tomorrow. Keep that in mind even as the heat backs off. All these fires now, north, west, east, and south, were going to be dealing with air quality issues for the next few days. Temperatures you saw on the fire lines, still pretty hot across the higher hilltops. 80s inland for now. No sign of a sea breeze just yet but that should change mid afternoon today. We start the day with warm temperatures, mid70s inland. Highs for more one more day will still get to 100 degrees in the hottest plays. Milpitas, pleasanton, livermore above 1 hin degrees. Low aint towards oakland. Around the peninsula, temperatures in the 80s around san mateo. Mid 70s closer to San Francisco and north bay locations at least in the valleys in the mid90s but higher up where those fires are burning, still temperatures close to 100 degrees. So the excessive heat should be done officially at 9 00 tomorrow night. You can see by thursday now, theres your cooldown. You kind of have to look for it. Even though temperatures inland would be about a 10degree drop from the high temperatures were expecting tomorrow. So a short, Welcome Change in terms of the cooling thursday into friday. We start to see some relief, may also help the states power reserves. But halfway through the weekend, temperatures rebounding again. So less than 24 hours to go for this particular heat spell. Well be watching for warmer temperatures again, we think, early next week too. We do this every year, guiys but nothing quite like this, rob. Thanks so much, rob. Still ahead, signs things may be slowing down. An important update on covid19 from californias top health officer. And we have jimmy.

Cautious optimism from the states top health officer. Dr. Mark ghaly says the pandemic here is stablizing. Today the state reported 4,600 new cases, the lowest number in several weeks. Overall the state picture is stabilizing and coming down some, but as weve always said, this is not about the aggregate. It is about whats experienced at the county level, at the regional level. Dr. Ghaly says cases and hospitalizations are trending downward. The largest covid testing site in Northern California is up and running in san jose. It opened today in san jose in an empty lot of the Santa Clara County public fairgrounds. The site will eventually be able to test 5,000 people a day. Here are the details. You do need an appointment, but once you get one, you can drive up, walk up, or even pedal up to get your test. In the fall, flu vaccines will also be offered at that site. All right.

Heres the other problem is that its still daytime hot and dry outside. 80s and 90s across the hills and on radar, being able to see smoke plumes is high enough that radar can pick them up at night tells you thats daytimelike fire activity.
