majestic mountains... scenic coastal highways... fertile farmlands... there's lots to love about california. so put off those chores and use less energy from 4 to 9 pm when less clean energy is available. because that's power down time. good morning. it's 7:00 on this saturday, may 8th. a live look outside in north san jose. the sun is shining ahead of a very sunny mother's day weekend. thank you so much for starting it with us. i'm keira clapper. do not just your televisions. i had to adjust my eyes.

vianey is off for some well-deserved time off this weekend, but meteorologist rob mayeda is here, physically, back in the studio. the first coworker i've had in 14 months and i'm literally looking at him, i don't know, 12 feet away. >> so close. as you said, 14 months. >> so close, and yet so far. great to see you. >> likewise. and we've got to come through for keira and the rest of the moms this mother's day weekend. temperatures will be really warm around the bay area, but that will cause issues for some of the hilltops and fortunately with the red flag warnings. for the morning, we have these cool temperatures, 51 degrees currently in san francisco. east bay, walnut creek, 53 degrees. and our final stop takes us to san jose. more of those clear skies at 52 degrees. watch these temperatures, going from the 40s and 50s this morning by about lunchtime, you'll begin to see these temperatures climb into the 80s, right around lunchtime, and eventually, some places inland like fairfield out towards concord, could see those numbers climbing closer to 90 degrees

today. for the inland locations including contra costa county, inland alameda county through the tri-valley, east bay, valleys, north bay hills, and east bay hills, the red flag warnings thereby underway through monday morning, 6:00 a.m. and you can see just how dry things will get as we head into the afternoon. you see those numbers in the single digits for relative humidity. a closer look at those wind gusts coming up hour by hour in the forecast coming up a little bit later from now. >> about 15 minutes. i was corrected in my ear from our director, erin, that i have had coworkers for the last 14 months. i've had two coworkers for the last 14 months, but you're the only one in the studio. it is great to have you back. we'll see you in 15. we begin in contra costa li grizzly peak in the berkeley hills. sunny and beautiful. one of the popular spots that will be closed this weekend because of the high fire danger. this as firefighters in the east bay are bracing themselves. they say if a fire sparks,

conditions are ripe to quickly spread. similar to what we saw with the lmu, cbu, and sbu complex fires last year. today, cheryl hurd as a new warning from firefighters to people who want the enjoy the trails this weekend. >> reporter: tonight, people who use blind ridge open space in concord are getting their last bit of exercise in before the area will be off-limits. eduardo martinez finished his ride around 7:00. >> i feel like this year for the fire danger will be really dangerous. a lot stronger than last year. >> reporter: and last year was pretty bad. this map shows the entire san francisco bay area in extreme drought conditions, which gives the national weather service no choice but to issue a red flag warning this weekend. >> we know the '91 fire took place in october. when i started working for the city of oakland, september, october, is when we would see these wind events come through.

and now here we are in may and we're starting to see these events being forecasted. and it puts the hair up on my neck and puts us all at a heightened level of concern. >> reporter: starting tomorrow, all east bay regional parks will be closed. there will be no access to the grizzly peak lookout in the hills, and with mother's day on sunday, don't expect to be able to barbecue in the park. >> we will have our resources out patrolling. they will be looking for any potential starts. >> reporter: contra costa fire protection is partnering with other agencies to reposition their wildland engine task force, just after sunrise. fire officials are asking for the community's help. >> if they haven't already done it, to buy us time to save structures if a wildfire does occur. >> there have been a high number of grass fires burning or threatening homes already. fire officials expect this to be a long and dangerous fire

season. in concord, cheryl hurd. >> so will pg&e implement power shutoffs ahead of these strong winds? they say no power shutoffs are planned at this time. we'll let you know if that changes. you can keep track of the wind, the heat, the fire danger this weekend with our nbc bay area app. it is free. you can even get the forecast specific to your neighborhood. >> now to a fire in the east bay, where firefighters say power lines went down and pg&e was called to fix them. you can see those flames just bursting out of the home. this was around 11:30 last night. no word on any injuries. happening today, the city of alameda is considering changing the way police respond to 911 calls. the vice mayor called a special meeting with the city council for this afternoon. the hope is to move forward with recommendations on how police take action. some of those recommendations are to provide immediate crisis

intervention training for all dispatchers and officers. to create protocols for mental health crisis calls, and to create a citizen's police accountability board. this all comes after the death of mario gonzalez, whose photo you're seeing. gozalez died after being becontained by alameda police officers last month. police say he suffered a medical emergency. now to questions surrounding an officer-involved shooting in san francisco. police say a suspect in a car burglary was shot in an undercover operation. but now police with knowledge of what happened say that suspect was not armed and didn't need to be shot. "today in the bay's" jean elle reports. >> reporter: investigators from several san francisco agencies collect evidence after an sfpd undercover auto burglary operation ends with police shooting a suspect on bernie's place near soma south park. >> the officers encountered a known auto burglary suspect's

vehicle, which was occupied with at least three suspects in the vehicle. >> reporter: a witness said he heard one gunshot as he walked back to work from a lunch break on brannon street around 12:45. >> you heard a loud gunshot pop off, saw people scattering left to right, and i saw a couple of undercover cops running around looking for a suspect. >> reporter: police say one man was shot, taken to the hospital with nonlife-threatening injuries. witnesses say this is video of the two other suspects speeding away down barney place towards third street with their hatchback open. police say they got away. tonight, sfpd won't say how many shot were fired or if the suspect had a weapon. >> any information regarding the possession of a weapon is all part of our investigation. >> reporter: but sources with knowledge of the incident say the suspect was not armed and the shooting is being investigated by the department as an accidental discharge. sources also say the suspect was

shot in the hand. sfpd says it will share more information about this officer-involved shooting at a town hall meeting within ten days. in san francisco, jean elle, nbc bay area news. we also have new details on this story out of antioch where officers say they found an 18-year-old woman shot in the chest lying front of a home on sunset lane. they discovered her just after 6:00 last night. they tried to give her first aid, but she died. with no arrests made, antioch police urge anyone with information to call them. as federal regulators continue to evaluate the potential use of covid-19 vaccines in children, there's been a rise, a concerning rise in the proportion of covid-19 infections in children over the last few weeks. this is new data released by the american academy of pediatrics. i want shows that children are now making up 22% of coronavirus cases. although that rate of infections among children has remained relatively unchanged for the last several weeks.

a pediatric epidemiologist at stanford says that if vaccines are approved for kids, those rates would likely plummet. >> having vaccines again gives you a huge layer of protection, that goes above and beyond what we can do with masking and social distancing, et cetera. >> dr. lee also says in the bay area, there's a higher rate of adult vaccinations, and that provides a layer of protection for our children. federal regulators are expected to announce a decision on the use of the pfizer vaccine for 12 to 15-year-olds some time next week. now to a live look over the san francisco skyline. the sun is already shining at 7:09 a.m. it's the first weekend that the city and county of san francisco is now in the least restrictive yellow tier. it's the only bay area city to be in the yellow, meaning many places can expand capacity rates, bars can also drink withou

and down in san jose, hazy, sunny skies. county health leaders are hoping to move into the yellow in a few weeks. santa clara county health leaders say the county has a case rate and positivity rate low enough for the yellow tier and they don't expect things to start opening up right away, though. >> we need to wait at least two weeks in order for us to be able to move into the yellow tier. in other words, in about two weeks, potentially, if the numbers continue to be down, then we potentially can move into the yellow tier. >> most bay area counties are in the orange tier right now. health leaders continue to stress the best way to make sure that santa clara county reaches the yellow in two weeks, is to get vaccinated. at 7:10, we have much more ahead on "today in the bay." coming up, no criminal charges. that's the district attorney's decision for the walnut creek police officers who shot and killed a man having a mental health crisis. the action his family is taking to continue their fight for

justice. plus, bracing for impact. the nine-story-tall rocket body is hurtling out of control around the earth. the reason world leaders say they aren't concerned about where it will land.

california's choice beauty? pretty boy. or a beast? john cox grew up with nothing; made himself a remarkable success. california's falling off a cliff. high taxes, unaffordable costs! even elon musk left! gavin's mismanagement of california is inexcusable. we need big beastly changes in sacramento. i'll make 'em. recall the beauty. meet the nicest, smartest beast in california. john cox.

welcome back at 7:13 on your saturday morning. a live look at san francisco and the bay bridge. the sun is shining. we are in a red flag warning only the second red flag warning in the month of may since 2013. it is early in the season. meteorologist rob mayeda has the heat and the wind in about four minutes. the family of a mentally ill man killed by walnut creek police say they will continue to seek justice despite the district attorney's decision not to charge the officers involved. after a months-long investigation, the contra costa county d.a. announced yesterday there is insufficient evidence to prosecute the officers

involved in the 2019 shooting of miles hall. the confrontation began when hall's family called police to report that he was suffering a mental health crisis. officers ultimately shot hall after they say he refused to drop a metal gardening tool. the d.a.'s report says the officers feared for their lives. >> he was running in the general direction of them. he was carrying the black digging tool at his waist and he wasn't listening to their commands to drop the tool and stop. >> he was our bright light, he was our sunshine, he was beautiful. and he was -- he was -- he had mental illness. i mean, if you have mental illness, you shouldn't be criminalized. >> friends and family protested the d.a.'s decision in front of the walnut creek city hall yesterday. hall's family says they plan to ask the state attorney general and the u.s. department of justice to review the case. we do have much more ahead on "today in the bay." coming up, drought levels continue to grow and so, too, could your water bill.

the possibility of an increase by nearly 150%. and from drought to fire danger, one of the spots today under the red flag warning includes walnut creek. cool for now. 53 degrees. we'll talk more about the top wind gusts and temperatures near 60 degrees coming up.

people today... they could spend half their lives over fifty. that's a lot of living. so, it helps to have a wise friend and fierce defender in your corner. a friend like a-a-r-p. so your health lives longer. this is just slo-mo karate? just slo-mo karate. your money lives longer. hey, i just bought that. huh, i just sold that. and your happiness lives longer. that's why the younger you are, the more you need a-a-r-p.

join today. welcome back. at 7:17, a gorgeous look at the golden gate bridge. the sun is shining. we do have fire danger this weekend. meteorologist rob mayeda has your forecast in just a moment. but first, happening now, concerns about possible debris from a chinese rocket expected to fall back to earth some time today. u.s. space command expects the debris to drop down to earth, but won't know where until hours before reentry. they also think a big chunk of the debris will burn off when it hits the atmosphere, so before it hits the earth. california's drought is on track to drive up water prices

across the state. in the south bay, the valley water district is looking to raise rates by nearly 150%. the hike would pay for a $2.5 billion project to expand the pacheco reservoir. valley water says it's key to protecting the area's future water supply. the san jose mayor sam liccardo argues it's an overpriced mistake. he wants to invest in other strategies. the water board votes on the rate hike on tuesday. perfect time now to check in with meteorologist rob mayeda for a look at our microclimate forecast. we have heat, we have wind. it's not a great recipe for this mother's day weekend. >> and you just mentioned drought. that is a big driver of the fire danger we're seeing now. if you go back until last october, typically the peak of fire danger. this is how the drought monitor looked around the bay area. but you move forward now to what we have outside at this moment. may, these numbers should not look like this after winter, they should have improved

somewhat. but they switched all the way down to monterey bay. you add dry north winds. this fire danger certainly off to an early start this season. right now in san francisco, sunshine, no fog. you've got 52 degrees. similar conditions, temperature wise in san jose, with more sunshine for now, in the low 50s. but out towards walnut creek, 53 degrees. winds atop mt. diablo, though, just to the east of downtown, already gusting about 50 miles per hour. those high wind gusts across the hills, generally above 1,000 feet today gets that red flag warning started last night at 11:00. interior east bay valleys, the diablo range. also up towardsoing to be ongoi the way through 6:00 on monday morning. so notice our temperatures today with the dry offshore winds, looking more like summer around the bay area. mid-70s near san francisco. low 80s into oakland and hayward. san jose, about 84 degrees. and the warmest places today will be around napa, over to concord, livermore, and fairfield with upper 80s to near

90-degree temperatures will be around today. and we could be seeing this through about tuesday. now, in terms of the peak winds, not seeing much down towards sea level. the top gusts right now, fairfield, north of 30 miles per hour. and on this map, you can see where the peak gusts will be. mainly near the diablo range. gusts 20 to 30 miles per hour, but it's the very dry conditions, unlike the sea breeze, watch what the heating and that dry offshore breeze does. down possibly to single digits at times. no coincidence, it's the inland east bay seeing these red flag conditions through monday. in the seven-day forecast, you can see san francisco climbing from the 70s all the way through about tuesday. then the sea breeze picks up air-conditioning return and for the coastal fog. and for the bay and coast, that should bring fire danger down. inland areas may actually warm up a little bit more. we've got mid-80s as an average for most of our valleys today.

as we go through mother's day tomorrow, should be just fine for brunch with mom. but look at those temperatures getting closer to 90 degrees on tuesday. so unfortunately, red flag warnings will carry us through about monday morning. a taste of summer through tuesday. and then some cooling as we head towards the end of next week. you know, typically, we see these red flag warnings popping up, maybe june, july, into august, but this year, this is the second one we've seen in may since 2013. more dry weather in that seven-day forecast. >> yeah, not a great factoid there. but i learned it from you, so thank you for sharing it with me. good to know. and just fingers crossed for all of our safety. 7:21 right now. still ahead on "today in the bay" -- >> the first few days -- >> his career almost ended before it even started. we'll introduce you to the south bay water polo player who overcame the odds and will be wearing red, white, and blue for team usa in tokyo this summer.

but first, it's time now for our clear the shelters segment featuring our friend from pets in need. this is missy. a 6-year-old pit bull mix. she walks well on her leash, knows several basic commands. her foster parents say she's well behaved and knows where her boundaries are. she loves to lean on you, sleep on you, and can sleep through all kinds of loud noises. missy isn't a fan of other dogs, so she would be a great family for family looking to add her as their first pet. you can find out more about missy by going to petsinneed.org or gi giving them a call.

we are now just 75 days away from the olympic games if tokyo. and for many members of team usa, it will be their very first time in the spotlight. that includes a u.s. water polo player from fremont. garvin thomas introducesnear-de journey to the games.

>> turner slapped it away. jack turner closes the door in front. >> reporter: this summer when you watch jack turner play water polo, this is an athlete whose clear almost ended twice. the first full-time coming the very first day he ever tried the sport. >> i remember almost drowning on multiple occasions. you know, face underwater, just being like, oh, my god, how is this even possible, right? >> it was not just possible for jack, it was a perfect fit. after playing for bell hamm, jack headed off to the university of california san diego, where he says he truly became serious about the sport and reaching its highest levels. >> i think what we made fall in love with the sport is how physically intimidating it was. i want to take this as far as i could. >> just blocked by turner. >> reporter: and jack was doing just that. playing for the national team when on a stretch of highway 101

in gilroy in august of 2017, jack's career almost ended for a second time. returning late at night from a competition, a tire blew out on his pickup truck. >> at the time, i didn't know that i had broken my neck, but turns out i had fractured the c2 and c1 vertebrae, which is the first two right after the skull. the first two days, it was whether or not i'm going to be able to do things that i ever loved again like play water polo, surf, walk. definitely some dark days. >> jack, fortunately, could walk and taking it step by step made it back to the national team in just five months. knowing his olympic dream came that close to ending, jack knows jumping into the olympic pool in tokyo will mean that much more to him. >> our quarter final games will be on the four-year anniversary of the accident, and that's like the biggest game, right?

you have to win that one to make it to the medal rounds. so i think that day is going to kind of be like a day of reckoning for me. it's going to hit me all at once. >> reporter: of course, because of the pandemic, jack has had to wait one more year for that day to come. he says that wasn't a problem, though. overcoming challenges, well, that's something he's gotten pretty good at. >> if i could get through the car accident, i can get through this. >> reporter: garvin thomas, nbc bay area news. >> we wish jack turer all the best. we'll be rooting for him. still to come for "today in the bay," a red flag warning for this mother's day. dangerous weather conditions and fire danger. in two minutes, meteorologist rob mayeda will tell you the most worry sometime.

good morning. it is saturday, may 8th, 7:29 as we take a live look outside over walnut creek. good morning to you out there on

this sunny saturday morning, thank you so much for joining. i'm kira klapper. vianey is enjoying some well-deserved time off. we have meteorologist rob mayeda not only filling in, but physically in the studio, the first coworker in the studio, i should say, that i've had in 14 months. everyone else is behind the scenes, making the magic happen. so great to see you. >> likewise. i had to come in for mom's day weekend. make sure off good forecast for tomorrow. temperature wise, you're looking great. it's the fire danger in the hills. the offshore winds helping to clear our skies, right now setting up to a mild cool start to the morning. not a lot of wind, but in the hills, up towards mt. hamilton or mt. diablo, we're seeing gusts close to 50 miles per hour this morning. notice the temperature trend as we head towards lunchtime. you're leer near 80 degrees or 82 out towards fairfield. highs today, fairfield and concord, close to 90 degrees. you see the warm conditions,

mid- to upper 80s around the tri-valley. mid-80s around san jose. the areas we're watching closely will be the inland east bay valleys, including the tri-valley, out through solano county, walnut creek included, north bay and east bay hills through 6:00 a.m. on monday more those dry offshore winds, gusts above 40 miles per hour and look what it's doing to the humidity numbers. by mid-afternoon, dropping into single digits. a closer look at how long the heat could stick around in our forecast in about 15 minutes. >> we'll see you for that, rob, thanks. we begin right now in the berkeley hills sticking with the weather. this live look at grizzly peak, a beautiful view. that's why it's a popular spot for people hiking the east bay trails, but it will be closed this weekend because of the high fire danger. firefighters are bracing themselves. they say if a fire sparks, conditions are ripe to spread quickly. it's similar what we saw last

year with the complex fires. >> reporter: tonight, people who use lime ridge open space in concord are getting their last bit of exercise in before the area will be off-limits. eduardo martinez finished his ride around 7:00. >> i feel like this year for the fire danger will be real dangerous. a lot stronger than last year. >> reporter: and last year was pretty bad. this map shows the entire san francisco bay area in extreme drought conditions, which gives the national weather service no choice but to issue a red flag warning this weekend. >> we know the '91 fire took place in october. and now here we are in may, and we're starting to see these events being forecasted. and it's -- it puts the hair up on my neck and puts us all at a heightened level of concern. >> reporter: starting tomorrow, all east bay regional parks will

be closed. there will be no access to the grizzly peak lookout in the hills. and with mother's day on sunday, don't expect to be able to barbecue in the park. >> we will have our resources out patrolling. they will be looking for any potential starts. >> reporter: contra costa fire protection is partnering with other agencies to reposition their wildland ten-person crew engine task force just after sunrise. fire officials are asking for the community's help. >> defensible space creation if they haven't already done it, to buy us time to defend structures if a wildfire does occur. >> reporter: there has been a high number of grass fires burning or threatening homes already. fire officials expect this to be a long and dangerous fire season. in concord, cheryl hurd, nbc bay area news. will pg&e implement power shutoffs ahead of those strong

winds? the utility company says no power shutoffs are planned at this time. we'll let you know if that changes. you can keep track of all the wind, the heat, the fire danger this weekend with our nbc bay area app. it is free and you can tailor to it your specific neighborhood. happening today, the city of alameda is considering changing the way police respond to 911 calls. the vice mayor called for the meeting, hoping to move forward with recommendations on how police take action. some of those changes could include providing immediate crisis intervention training for all dispatchers and officers, creating protocols for mental health crises, and to create a citizen's police accountability board. this all comes after the death of mario gonzales. you saw his photo a moment ago. he died after being detained by alameda police officers last month. police say he suffered a medical emergency. right now the covid vaccine record card is the closest thing we all have a universal vaccine

passport. it's important, but what if the information on yours is wrong. nbc's chris chmura shows us how to fix it. >> reporter: jennifer says the clinic who gave her her card wrote "tracy" on her medical card. the cdc said vaccine recipients can access their vaccine record by contacting their vaccination provider. for many people, contacting the vaccination provider will be easy. but in jennifer's case, and a lot of other people, she went to a mass vaccine site. she wasn't able to contact them and lots of them aren't going to be there forever. they might already be gone. so what do you do? the cdc said if you cannot contact your vaccination provider directly, contact your state health department's immunization information system. in california, you can call 1-800-578-7889 and press 6 to talk to someone.

the agent said jennifer can go to her doctor who can correct the card or ash new one. and the doctor can update the database to show that tracy wasn't vaccinated, but jennifer was. the cdc recommends 15 to 20 minutes of downtime right after the shot. during that time, look at your card, confirm everything on it is accurate and if it isn't, speak up right there. >> chris chmura with us for the great info. elon musk will host tonight's "saturday night live." the tesla and space-x founder was spotted signing autographs in new york city yesterday. the decision to let him host has drawn some criticism for his comments about the pandemic. he's known for a wry sense of humor. miley cyrus will join musk as musical guest. you can catch the show at 8:30

and 11:30. and it's 7:36. still to come on "today in the bay," using artificial intelligence to detect wildfires. new technology that local fire crews say is giving them a leg up before fire season. we'll be right back.

numerous devastating fires have forever changed lives in sonoma county. fire crews are on alert this weekend and they'll have the help of artificial intelligence. as we previously reported, sonoma county is using ai to monitor its network of wildfire cameras. you can see in this example here, when it detects smoke from a fire, the system sends an alert to dispatchers who can then verify that a wildfire had sparked. county leaders say after a few months of testing, it's showing great promise. >> tuesday, we did have a small vegetation fire in sonoma county and the system actually detected the fire ten minutes before the

first 911 call reached our dispatch. so we're finding that very encouraging that if we can keep that up, that the system may be able to give us advanced notice. >> and here's a look at the system in use right now. the county first started testing the technology in march. there are 21 cameras that can detect wildfires in sonoma county and there are plans to soon add six more. coming up on "today in the bay," we investigate a place in san francisco many homeless turn to shelter endanger the pandemic. is the air around it putting their lives at risk? and we've been watching those changes occurring across some of the north bay and inland east bay and the north winds now picking up into fairfield north of 30 miles per hour. that's what's really driving our fire danger and red flag conditions today, including walnut creek. 50s for now, upper 80s later. a closer look at that in your forecast when we come back.

so far this saturday morning, starting off with a sunny start, but unfortunately a microclimate weather alert for some dry, gusty conditions and a red flag warning on the higher peaks of the north bay. you can see a beautiful view here from our sutra tower camera looking over the golden gate bridge. those dry conditions fog-free in san francisco. you can see 52 degrees, not much wind and the humidity not too bad, at least closer to the bay. but things begin to change a bit farther inland. the north wind is starting to pick up. san jose, 52 currently. not much wind in san jose. but dublin, areas out towards livermore, concord, walnut creek, you'll be seeing those dry breezes picking up a little bit. dublin, by the way, one of the locations under that red flag warning. it will be the inland east bay diablo range, north bay hills from now through about 6:00 on monday morning. so notice the wind direction here through fairfield. 30 miles per hour to the north. that is a very dry breeze, which will mean not only the dry conditions and fire dangers you can see for most of the inland

east bay, already taking effect since 11:00 last night. gusts here in the higher hills above 1,000 feet to 2,000 feet, anywhere from 30 to 40 miles per hour. and you can see that does extend into the north bay and the higher hills here of marin county and napa county through 6:00 a.m. on monday. another thing you're going to notice, if it's not the wind, it's just how warm it is outside. temperatures climbing through the 80s for most of the valleys and out towards fairfield and concord, close to 90 degrees today. you see san jose, 84 degrees. 75, san francisco, upper 80s around santa rosa and numbers through the low 80s into concord and hayward. the effect of that dry offshore breeze, really being seen with humidity numbers which aren't that bad this morning. but look what happened this afternoon. single digits into parts of napa county, al mee dad, contra costa counties. that coupled with the wind is why we have the red flag warnings and similar conditions expected on sunday as we head towards sunset, those numbers improving just a little bit. but wind speeds will stay the strongest, i think, through

inland napa county. the higher peaks there. the diablo range, you can see those gusts 30 to 40 miles per hour. and wind speeds coming down a little bit by the time we get to monday. san francisco, temperatures staying in the 70s. in fact, we'll probably see another rebound of those temperatures monday before things cool off and the sea breeze picks up. and for the valleys, numbers in the upper 80s to near 90 degrees. hottest day of the week, next week could be tuesday. and trending cooler as we head towards next weekend. >> kira? >> wow, 90! rob, thanks for that forecast. we'll be right back after this. stick with us.

this unplugged device is protecting our beautiful coastlines and more. put off chores and use less energy from 4 to 9 pm to help keep our state golden.

welcome back. it's just shy of 7:48 on your saturday morning. we are under a red flag warning. you can see the sun shining in san jose. it will be windy across the bay. that means high fire danger. rob mayeda has that last look at your weather in about seven minutes. many in the homeless community found a home away from the pandemic thanks to a government-funded shelter. but now some fear the very air around it could be putting already vulnerable lives at risk. jackson vander hecken has our exclusive story. >> i mean, we've got it made, pretty much. >> reporter: derek barnes is proud to call trailer 175 home. >> the executive suite. that's what i call it. because that's what it looked like when i first walked in. >> reporter: it's on railway

welcome back. here's a quick look at the top stories we're following this saturday morning. will the city of alameda change how their police respond to 911 calls? there will be a meeting today to look at recommendations like providing immediate crisis intervention training for all dispatchers and officers. creating protocols for mental health crisis calls, and creating a citizen's police accountability board. this all comes after the death of mario gonzalez, whose photo you see there. he died after being detained by alameda police officers last month. police say he suffered a medical emergency. and new details on this mysterious story out of antioch. officers say they found an 18-year-old woman shot in the chest, lying in front of a home on sunset lane. they discovered her death after 6:00 last night, tried to give her first aid, but she died. no arrests have been made. antioch police urge anyone with information to call them. and now to this fire in the

east bay. firefighters say power lines went down and pg&e was called to fix them. you can see those flames erupting from the home. this happened around 11:30 last night. no word on any injuries. and as rob has been forecasting, we are under a red flag warning. it's going to be a hot, windy weekend, vegetation is already dry. all east bay regional parks will be closed today because of that high fire danger. there will be no access to places like the grizzly peak lookout in the berkeley hills. and although those hot and dry and windy conditions are expected, pg&e says they will have not have any planned power shutoffs this weekend. we'll let you know in that changes. and let's check in with meteorologist rob mayeda who has a quick last look at that red flag warning. >> kira, you did mention all of those impacts to the east bay parks. and the biggest impact will be across the interior east bay. the reason why we're starting the weekend with a microclimate weather alert.
