as we go to live doppler 7 right now, check out this view of all the lightning strikes over the entire bay area. so we're not talking only the north bay, but they all started yesterday from san luis obispo moving up overnight you may have seen a few high clouds. look at the surge of moisture. there is moisture associated with this, not just dry lightning but as we go into the coast there, you can see inverness, san rafael, penngrove and santa rosa and haelealdsbur it's raining. more thunder and lightning over towards livermore, and as we take you further to the south bay, not to be outdone in the south bay, currently looking at a thunderstorm with lightning in campbell, up through san jose. so as we go through the next several hours, not only have we our heat warnings and excessive heat watch but we're looking at a red flag warning extended

through monday. look at the temperatures, 5:00, it's 84 degrees in concord, 82 no novato. we haven't cooled off overnight. this adds to the heat stress. we'll get hotter today and ke vy ch, because the rms, w excessive heat is at the surface, and we're going to continue to see this dome of high pressure overhead. wind gusts to 31 miles an hour here in the city, and that red flag warning through monday, you can see the dangerous heat wave takes us through wednesday. starting out with the clouds, the rain, the lightning, clouds will thin out and look at that, 100 degrees there in the east bay and some sunshine, another steamy afternoon. liz? >> all right, lisa, thank you. cal fire says it is at the scene, we got this tweet in from them, seven vegetation fires in san mateo and skroouzz ti. psib stard by the widespread lightning.

that is a concern we'll be tracki tracking. for the second night in the row pg&e was ordered by the agency to rotate power outages. it's unclear there until be any more planned outages today. the outages affected up to 220,000 customers in the central valley and central coast, including monterey, santa cruz and san joaquin counties. pg&e says power was restored about 9:30 last night. and the state agency cal iso said there wouldn't be outages, but said the change of plans was made due to increased electricity demand and unexpected loss of both a power plant and some wind power. here is a look the at the current outages here in the bay area. a pg&e spokesperson tells us there were several heat-related outages. we're hearing there are some outages related to this morning's thunder and lightning, but it's unclear how many people are impacted by that right now. the outages labeled with yellow on this map are affecting more than 50 people. the orange labeled outages are more than 500 people, and the

red labels are affecting more than 5,000 customers. we're seeing that in just one or two places around the bay area. some people experiencing outages had been without electricity since friday night and abc 7 news reporter luz pena talked to some families who have simply had enough of this heat wave. >> reporter: it's the second day in a row that thousands across the bay area are in the dark. >> thinking, like regular people, well, you know what? it will be on in a little while, and we'll be good, right? well, this morning, still no powed okay, now you really star to worry, because then i start worrying about all of the food that i have in the fridge. >> reporter: in san jose, teacher mariana garcia is one of over 4,000 pg&e customers affected by rotating power outages. unlike many who got their power back, it's been over 24 hours for her without electricity and her bigges having a lesson plan ready for her students.

>> usually what happens is over the weekends, you plan your lessons, you make sure that everything works, start posting your things to google classroom and all of those good things that technology allows us to do. well, i'm not able to do that, and so i am crossing my fingers that monday morning i'm going to be able to actually go into my school site, but to at least obviously prepa lessons. >> reporter: the outages were expected to affect approximately 220,000 pg&e customers. in the east bay, thousands were in the dark, with temperatures reaching over 105 degrees, driving was a saving grace for many. >> the only air conditioning we got is my car, so luckily, my tank is full and we've been cruising all over. >> just having the air conditioner because with my health issues, i fire protection district is gearing up to respond to potential fires. >> they're expecting thunderstorms with lightning strikes, so if we have lightning

during this very hot weather, we are concerned about the number of vegetation fires that we'll have. >> reporter: a red flag warning went into effect at 11:00 p.m. in contra costa county. >> we called back additional staffing, we have our crew 12 which is our hand crew that assists with vegetation fires. we have an additional chief officer working tonight and we also have our dozer on standby. >> reporter: in livermore, luz pena, abc 7 news. there are ways to help conserve energy and maybe avoid outages trying to beat the heat. set your thermometer at 78 degrees fahrenheit or higher and keep the house cooler with fans instead of the ac and draw your curtains to block the sun. turn off up necessary lights and appliances and use major appliances in the morning or late evening. higher rates are usually charged between noon and 8:00 p.m. in the summer. and a warning for swimmers

andew stay close to shore while trying to beat the heat. abc 7 was out at ocean beach in san francisco yesterday where three teenaged surfers were rescued. one had to be given cpr and is in critical condition. the others were able to walk to the ambulance. san francisco fire tweeted they made eight surf-related rescues in and one cliff rescue yesterday. they responded to around 700-safety-related calls. a fire damaged a building deyed drirs along a stretch of freeway in san francisco. people saw smoke rising miles away from the scene after the fire started along the southbound lanes highway 101 near paul avenue. here is how it looked for drivers headed in the opposite the fire appeared to start behind a building that houses a construction company and fire swigt fighters believe someone

may have set it. >> part of our suspicion our companies have been here several times in the past couple months for similar outside fires. >> lanes were closed for about 90 minutes because of this. and 50,000 gallons of raw sewage spilled into the oakland alameda estuary friday night because of a power outage, according to the east bay municipal utility district. the outage caused a failure at its main plant near the been been and people are being told to avoid the water now for several days. >> it's a dilution issue and we'll be sampling water along the estuary and when the water is safe we'll let the public know that they can go back in. >> east bay mud had no warning from pg&e that the power was being cut. pg&e has not commented. east bay mud says it has to pay a fine for that spill.

dozens of people relied on a cooling center to avoid the heat in san jose yesterday. visitors had to get their temperature checked before entering the community center. city workers set up seating and tables, as you can see, in a way that visitors could still socially distance from one another, but one woman says she's not worried about being indoors with strangers during a pandemic. >> to be completely honest, we're both over 70. if we die, we die. you know, nobody lives forever. >> one family turned to the cooling center when their power went out at home and work had to get done. >> ac wise, we can live without it, but power, you can't, right? batteries were draining it was down to nothing. you can't use your phone as a hot spot or anything. >> san jose will open cooling centers every day until wednesday. and remember, you can always check for where you live on your abc 7 news app and we'll send note fay indications on power outages or other breaking news.

make sure you set up the push alerts. lisa, let's go back to you. boy, it is pretty wild out there right now. >> it is incredible. what a light show. i don't know who could sleep through that and the gusty winds. we have more thunderstorms possible throughout the morning hours, but then this red flag warning is extended until monday morning, with another surge of moisture. so we've got several hot days ahead, with our excess self heat warning. my accuweather seven-day forecast is next. also ahead the i-team learned about a number of arests in connection with a scheme from california inmates received unemployment benefits. plus the crisis involving the postal service, protesters show up to the home of the postmaster general, accusing him of voter suppression, ahead of . of voter suppression, ahead of .

here is a live look from our east bay hills camera. keep your eyes on it. it won't take long before you see some lightning out there, quite a show. it's 73 degrees in oakland right now, and we are tracking the weather overnight this morning. developing news though, crews are battling the lake fire north of los angeles. the crews battling it say lightning strikes have caused serious setbacks. los angeles county fire tweeted more than 100 lightning strikes caused spotting and larger fires compromised the containment lines. look at that image there. the wildfire remains at 12% contained, 23 square miles have burned, that's around the size of palo alto. triple-digit temperatures fueled the fire which destroyed at least 21 buildings and is threatening 4,500 others. and you got to look at this, what's believed tbey the national weather service.

the loyalton fire burning outside of reno sparked a rare fire tornado and a fire tornado warning. the national weather service tweeted extreme fire behavior would continue this evening with new fire tornadoes possible. pretty incredible to see that there, firenados are an extreme weather phenomenon that have burning fire columns. the royalton fire is only 5% contained. we'll get back to the weather but let's talk about the turmoil in the u.s. postal service. president trump's newly appointed postmatzer general louis da joy imposed strict cost-cutting measures in lieu of the mail-in voting. noisy protesters oppression. rachael scott has more. >> reporter: millions of mail-in ballots at risk of not being counted, protesters lining up

outside the postmaster general's home, accusing louis da joy, a trump ally and gop donor of dismantling the postal service after putting place cost-cutting measures that critics say will slow mail delivery. >> louis da joy is working very hard. >> reporter: the president tweeting the democrats know the 2020 election will be a fraudulent mess, threatening to block funding for the post office unless democrats meet his demands on coronavirus relief. >> universal mail-in voting is going to be catastrophic. it's going to make our country a laughing stock all over the world. >> reporter: but the postarve dd ow6 states and washington, d.c., that their deadlines are incompatible with delivery standards and balance lots might not be delivered in time to be counted. and while the president continues to push unfounded claims that mail-in vote something linked to voter fraud -- >> mail-in balance lots will lead to the greatest fraud.

they're going to be rigged. everyone knows mail-in balance lot its are a disaster. >> reporter: joe biden pointing out the president just requested his mail-in ballot for the florida primary on tuesday. democratic leaders nancy pelosi and chuck schumer accusing the president of trying to suppress the vote, writing in a statement "he needs to cheat to win." >> so i would say definitely don't risk your health, vote by mail, but if you do, vote plenty early, buzz within this administration is an attempt to make sure your vote doesn't count and doesn't count as cast. >> reporter: rachael scott, abc news, washington. as part of abc 7's commitment to cover five major areas to help build a better bay area we focus on health and the latest on the coronavirus pandemic. there are more than 12,000 newly recorded confirmed cases friday, that total may include delayed test results here in california. the governor said california is caught up now its reporting of cases that were backlogged due

to a data glitch. the state reported 151 deaths, down 37 from the previous day. los angeles and riverside counties have the highest case counts in the state. and the abc 7 news i-team learned about aemy san mateo county jail inmates. sources tell the i-team 11 inmates used county-owned computers to apply for benefits, some of the inmates now face murder charges or some of them already had faced murder charges. the scam netted about $250,000. san mateo county sheriffs deputies and officers from other agencies arrested 21 people in three counties stretching from san francisco to the san joaquin valley. those suspects you see here include girl friends and friends of the suspected inmates. sometimes the best way to beat the heat is to enjoy a cold drink or snack like ice cream.

customers lined up to enjoy ice scream at swenson's in san francisco. swenson's has been making its own ice cream on russian hill for more than 70 years. and on abc7news.com we have a list of some of our favorite ice cream shops. i highly suggest you check it out and some of you have been chiming in with your own favorites. lisa, you've told me your favorite ice cream. i'm now forgetting. remind me. >> the problem is that the power is out. you shouldn't open the freezer or the refrigerator. you have soup instead of ice cream so that's my issue last night. so yes. you had the power out on saturday, friday night. i had it last night, so no ice cream, in fact, we are looking at an incredible light show oves interan interacting with a trough offshore. live doppler 7 is not only dry lightning obviously because the moisture with it, so it's just a regular thunderstorm interacting with the trough and this really came up from the south

convention follows the week after, but both events are going to look pretty different than previous years. this morning, we have a preview of what we can expect as they go virtual, and how one bay area trump delegate believes the changes could ultimately help the biden ticket. >> once again, the strength of democratic processes was demonstrated in the united states. >> reporter: it's a staple of our election process. every four years, thousands of the country's most politically active gather at the republican and democratic national conventions to formally nominate their party's presidential candidate. >> i humbly and gratefully accept your nomination for the presidency of the united states. >> reporter: but this image of this many people crammed into one convention hall space is clearly not 2020 safe. like so much else this year, the pan demme lick give a whole new as t see virtual tical traditie convention looks like. >> a the dnc, spe longer travel
