fighting what's become the largest single fire incident in california history. at least according to some. >> technically there are two separate fires, so as to whether it's the single largest fire in california history is up for debate. >> reporter: but the impact, clear and still present, 300,000 acres burned, 100 structures destroyed, 4,000 firefighters strained to the max. and a region transformed almost beyond recognition. >> this is -- >> reporter: the mendocino complex fire has created three kinds of people, who he has who've lost their homes, others exiled by mandatory evacuations. >> where have you been? >> everywhere, waiting for lake county to open. and those who have received the all clear to return home. when you drove away, where did you think you'd come back to? >> a burnt down park. >> reporter: so valerie green's relief when the blue lakes village rv park reopened and her tenants returned.

these are the same flames from which they ran last week, they encircled the park. >> it was loud, i mean, it was roaring and you could hear trees explode. pow, pow, pow. >> reporter: today michael morgan returned with no damage worse than the bumper he bent while escaping. a small price compared with what he thought he would lose. >> grateful. i'm in a grateful place. we feel blessed. >> reporter: so specifically here are some of the areas that have reopened. highway 20, west of upper lake, and south of pine avenue in potter valley, west of the mendocino lake county line. all of this changes with the weather and with the winds of the fire. cal fire is not taking any chances. live in mendocino county, wayne freedman, abc 7 news. >> wayne, looking behind you, it looks like a wall of smoke or haze that can be seen everywhere in the background. so a lot of smoke. how bad is it?

is it hard to breathe? >> reporter: well, you hear my voice right now. it's not the same voice we arrived here with this morning. it's hot. you feel it in the throat. you feel it in the nose, and you want to get back in the truck and turn on the air-conditioning. >> go do that and get some water as well. wayne freedman reporting, thank you. the mendocino complex fire is now the largest in state history. burned more than 443 square miles. to give you some perspective, that's a huge chunk of the bay area, from san francisco to san ramon, down to union city and half moon bay. >> there are nearly two dozen major wildfires burning right now in california. this map shows the fires, they're spread out all across the state. in the redding area, firefighters are battling the deadly carr fire, which has now burned more than 167,000 acres. it's at 47% containment. the ferguson fire, that continues to grow, now more than 94,000 acres, 43% contained, and it's the largest fire in the sierra national forest history and parts of yosemite national

park remain closed due to that fire. there's growing concern among s that california wildfires are expected to keep breaking records for size. the top two in state history have happened in the past eight months, the mendocino complex and the thomas fire. >> david louie at looked into why these catastrophic events keep setting records. david? >> reporter: well, larry and ama, take scorched sites like the one at the hill top behind me, and you can recognize how vulnerable california is to wildfires. across the state there is an alert being sounded to expect more and larger fires, including ones that will set new records for size. now, climate scientists are busy doing ongoing research, but they think they know why this is happening. . the power of wildfires can be numbing, knowing that lives and property are being lost. the battles to contain them, a combination of ground-based fire science, and precision air drops. what worries climate scientists is the intensity and size of

california's fires. creating a cycle of increasing magnitude. the mendocino complex fire has become the largest in state history. bumping last december's thomas fire in santa barbara and ventura counties to second place. what's striking is that out of the ten biggest wildfires in california, dating back to 1932, seven of them have occurred in the past eleven years. allison bridger is chair of meteorology and climate science at san jose state. she says there are two factors behind this pattern. one is tied to variations in warm and cold surface temperature in the mid-pacific. it's called oscillation. >> we're in part of the cycle where we're warmer and drier, and then we'll head to cooler and wetter. and that would be driven by giant, slow oscillations in the pacific ocean. >> reporter: the other culprit, she says, is climate change, which is raising temperatures during the cay and even at night when firefighters counted on cool weather to help.

>> relative humidity depends on water in the atmosphere, but also get rebound at night quite as well as you used to, as it's warmer overnight. >> reporter: the result is a cycle that shows no sign of ending. >> the fire's going to be more likely in a warmer world, more intense, spread a little bit further, therefore cover a bigger area. and therefore become the biggest fire in california history. >> reporter: now, if these larger, more devastating wildfires do materialize, that will have serious implications, including the need for more fire fighting crews, as well as key decisions such as whether to allow homeowners to rebuild after their homes have been raised by fires. >> david, thank you. in panol, firefighters put out a brush fire that started late trch. it spread to about ten acres. no homes threatened, nobody was

hurt. firefighters will stay on the scene to make sure this one does not flare up again. taking a live look outside. you can see the skylines above walnut creek and oakland have that smokey haze. the smoke from the wildfires across the state is so prevalent, it's even been detected in the midwest and southern tip of baja, california in mexico. near the ferguson fire in yosemite, people have been warned to stay indoors. on saturday the air quality tested at a level of five. that's the highest level of pollution. air quality officials say it's unclear when that air will clear up. >> and unfortunately it does not look like it's going to get much better. >> no, spencer christian is here with our forecast. spencer? certainly not getting better in the immediate forecast future. here's a look at our satellite image that's been showing the buildup of smoke in the central valley and in the sierra. you can probably tell if you've been following the last few days the smoke is more prevalent now. now, the air quality, as represented by these yellow and orange dots is not very good,

obviously, in the central valley, and over in the sierra. there are orange dots indicating the air quality is poor for sensitive groups, meaning those with respiratory elements and elderly and very young. the red dots indicate unhealthful air. in the bay area, it's been moderate to good so far. we have an air quality spare the air alert in effect for the bay area tomorrow. poorest air quality will be in the inland east bay, and not likely to see any improvement in the next couple of days. larry and ama? >> thank you so much, spencer. crews are assessing the damage by this violent hailstorm yesterday in colorado springs, golf ball sized hail pounded the cheyenne mountain zoo. 14 people were hurt and three birds were killed. it shattered skylights and windows on buildings and dented cars and broke windshields. zoo officials have never seen anything like it before. >> the search continues for the person responsible for that deadly shooting on the bay

bridge yesterday morning. a man was killed, two others were wounded, 31-year-old daryl stenet jr. from texas was killed in the early morning shooting. he leaves behind two boys, including a newborn. abc 7 news reporter amanda del castillo talked to the victim's father. >> reporter: he was working the music entertainment scene as an artist manager, promoter and marketer. >> i wdoing a job, and when the finished the job -- >> reporter: he was driving this black suv heading eastbound on i-80. someone in a silver or gray desan fired shots and killed him and injured two others. his fare says the family hasn't heard from authorities. once rumors hit social media he picked up the phone and called

the medical examiner himself. >> he said, yeah, he gave me some stuff, markings on his body. and i knew right then that was my son. >> reporter: a man family and friends have always called lil' poo. >> his mother gave him that name when he was two weeks old. >> reporter: his father tells us poo went by a different name for two young boys. he was dad to a 10-year-old and newborn baby. >> his oldest son adores him, you know, he's just -- he just thinks the world of him, think he's mister super man. >> reporter: for now they don't know what to think. >> i don't know how the process goes, i've never went through this before. and by all means, don't want to be going through it now. >> reporter: the two men with him were both taken to the hospital with gunshot wounds. we're told that one of them was released from san francisco general hospital yesterday. the second, we're told, is in fair condition.

>> reporter: that's right, larry, 11 for 11 in those primaries, but not so much when it comes to special elections. president trump only one for four in special elections when his choice, his pick faced off against a democrat. and tonight, really, the last real test between republicans and democrats ahead of the november midterms. larry? >> we'll see how it goes tonight. the prosecution star witness spent his second day on the stand in the paul manafort bank and tax fraud trial. rick gates testified how he falsified financial documents at the behest of manafort, his former boss, and former trump campaign manager. under cross-question manafort's attorney took direct aim at gates' credibility. he's accused of falsifying tax returns and -- tens of millions dollars he earned from a ukrainian political party with deep ties to russia. president trump reimposed the sanctions when he pulled the

u.s. out of the iran nuclear treaty in may. the penalties target iranian financial transactions that involve u.s. dollars, its automotive sector and its purchase of commercial planes. mr. trump backed the sanctions with a tweet warning that any countries doing business with iran won't be doing business with the united states. the european union countered by launching an updated version of a 1996 law that would prohibit european companies from complying with u.s. sanctions on iran. and there's a new report out that says american technology industries could be in the cross hairs in the ongoing u.s. trade war with china. according to the associated press, the trump administration's hit list of chinese products facing import taxes includes key components that are used in gadgets that can be wirelessly operated through a smart phone or another device. the tariffs would also hit networking equipment that makes the internet work. remains unclear how much prices might rise since the next round of tariffs might be imposed

bit more about what's going on in the ocean under the surface. >> one of the cool things, you guys have a partnership with the atmospheric -- they're docking a research vessel. >> on thursday, this week, a fisheries festival, part of the commerce department, part of what they do is make sure the fisheries are healthy. in order to really understand how much fish we can take from the ocean, we have to understand the ecosystem. so a fishery's vessel and does research. it does research on the little fish that big fish eat and about the ecosystem and plankton, the whole thing. every once in a while they'll dok in san francisco and people get a tour of the vessel. they can see the nets, the research, the fish finders, and talk to scientists. that's what operators all up and down our coast during the summertime. >> is that something that's good for all ages, can you bring little kids for that? >> absolutely. kids love it.

as long as they can walk up stairs, anybody can come on our research vessel and take a tour. the public is invited to come on saturday when it's free and open to the public. >> what are some of the other events people can partake in? >> tomorrow we're taking, we have a buoy, a red and white buoy measuring the carbon dioxide that's dissolved in the ocean. a lot of people don't know when you add carbon dioxide into the atmosphere, and it changes the chemistry. it affects shelled organisms and affects the health of the ocean. they want to know, especially since we're so close to an urban environment, what the impacts of that are. we're part of that partnership. >> you were taking a look at some of the video of that buoy, and this all is actually leading up to the global climate action summit in san francisco.

talk more about that. >> yeah, so the ocean is impacted by climate. the ocean actually moderates climate, but it's also impacted by global warming. so at the end of the month we're going to be a series of live ship chats with a research vessel in the arctic. arctic is one of the places that's changing the most. but the governor, i think, as part of really trying to understand what are the things that we can do as citizens, what are things we can do as people who live in california, our tech industries, what can we do to actually solve this problem. if the federal government's not going to do it, then we're going to do it, and the exploratorium is very much part of that, we are part of the summit, and we're hosting a lot of events. you'll have to check back with us. >> mary, thank you for coming in. we appreciate it. >> thank you. now your accuweather forecast with spencer christian. >> exploratorium is such a place. it's right across the street from where we are. clear skies.

overnight, we'll see a little bit of fog reaching across the bay, local inland. overnight lows manly in the mid to upper 50s, tomorrow's highs under mainly sunny skies. mid and upper 70s around the bay shoreline. mid-90s inland, but farther north we'll see 100 at lakeport 101 at ukiah. take a look at the tropical pacific where hurricane hector is a category 4 hurricane right now. it's expected to pass about 200 miles or so south of the islands on wednesday and thursday as a category 2 and 3 hurricane. still a strong storm, strong enough to kick up high surf and waves along the islands there and produce gusty winds. so a tropical storm watch is in effect. bay area, we have a warmup coming up. thursday, inland highs will reach near 100 degrees. we'll have a gradual cooldown going into the weekend. by sunday, temperatures are back in a more seasonal average range. >> sounds good. thank you, spencer.
