on to stop traffic behind us. that's when we saw the fire coming around the corner. one of the fire trucks pulled up, i think it was one of the first two trucks over to our left. and we just saw the flames get bigger and bigger and it was windy. so i just saw something i've never seen before. it looked like a fire tornado that's moving through, away from some of the fire trucks. honestly, we were just waiting for the thing to hop across the road. it was really neat to see how well the fire department worked, those guys are the real deal. >> it's scary though, we're looking at your video and we see how quickly the smoke just takes over the roadway there. >> oh, there was nothing stopping this fire, aside from the guys in the truck. and it was going the opposite direction from them, the wind picked up and it started moving quicker. i think one of the part of the video you can actually see there's -- the flames are coming

ten feet from the car. flames actually got up right to the front of the car before we backed up. it was coming onto the hood of our car. >> where are you now? at the time we were on marsh creek. we waited, the fire trucks had us stop on a certain part of the road, out of their way and helping block traffic. they were able to contain the thing to one side of the road. it starts going up a hill the trucks couldn't get to, and off to the races from there. >> you're no longer there to see what's happening. >> we were able to be evacuated after they contained the first part of it, and got the -- they had cleared the road from where we were at. and as we drove by, it looked like we were actually at the first 30 or 40 feet of a fire. what we got on video is just the start of wherever it is now. we're -- i'm in walnut creek,

and i can see mount diablo and the smoke is so much worse than it was eaier. >> that's not good, especially with those winds you were mentioning earlier. for viewers at home, we're showing you a map of where this grass fire is. as matthew mentioned, there were some first responders, some firefighters on the scene. but you saw how much smoke was coming off of that. there is a lot of open space out there. there are also homes in that area. we do have sky 7 on the way to the scene. so we can continue to give you updates as soon as we get them. we did hear that one structure was burning. yes, at least one structure is burning right now. so this is happening in clayton. >> yeah, we'll keep you updated as we continue, as soon as sky 7 gets above the scene and then we can get a better look from up high to give you a vantage point and determine exactly how many structures are in that area. because if there's other homes nearby, then they would certainly be at risk. we want to thank matthew for the video and the description. it's a good thing you got out of there. it's eerie and scary how quickly

you can see a brush fire can spread. fortunately they had crews there, and hopefully they can get it under control. we'll keep you posted. good afternoon, thanks for joining us. i'm larry beil. >> i'm ama daetz. get to today's other top story. >> so sad for my baby, that's all i know. just want justice. that's all. >> calls for justice from family and even strangers for the young woman killed at a bart station this week. >> 27-year-old john cowell appeared in an alameda court today. the district attorney is seeking a life sentence. melanie woodrow is at court today where she spoke with nia wilson's mother. >> reporter: it was a packed courtroom, dozens of family members that showed up here today, including stabbing victim latifa wilson. they were here, of course, for john cowell's first court

live where you 4rlive, thiss abc 7 news. we start this half hour with an update on that breaking news in the east bay. the contra costa county sheriff is calling for the immediate evacuation in marsh creek springs near leon drive and morgan territory road. this is because of a two-alarm grass fire burning along marsh creek road just outside of the clayton city limits. so far it's burned at least two homes, and we're joined live on the phone right now by a cal fire spokesperson. how many people are we talking about in terms of this

evacuation in that area? >> caller: well, you know, we don't have -- there's not a lot of homes out there, like you find as you move back towards up clayton and so forth. but there's enough. i'm going to say it's probably going to affect 50, maybe 60 structures in the area. so a couple hundred folks, if they're home or if they're trying to return home from work. >> what is the status right now of this fire? it was two-alarm when we came on the air at 4:00. we've seen the fire retardant drops, and we've seen some fire engines in the area. but what's the status overall? >> caller: so currently we're still looking at between 50 and 60 acres of grass and oaks that are involved in the area. i know that we've unfortunately lost a couple structures. and some outbuildings. there is still an immediate structure threat. we did request close to, oh, probably an hour ago, local government engines to help us with that structure threat. and then on top of that we've

got multiple cal fire engines in there helping to put this out, along with a minimum -- they had five air tankers come in and three helicopters. and if you've been watching some of the video that you guys have been showing, they've also got one of the real large air tankers in there working the area as well. >> looks like this is fairly challenging terrain. aside from battling it from the air. but it just looks like, given the heavy smoke, and the hillside here, this is not going to be that easy to deal with. >> caller: no. i mean, it's not going to be. i think the thing that is on our side at the moment is the winds are not real heavy. it's been reported to be about 10 miles per hour in the area. but it's going to take some time. we're in rolling hills out there. as you can see. and, you know, they're making good progress on it. but all of this fire is rolling through the grass underneath the oaks and it's just kind of creeping along.

hopefully the wind's not going to pick up anymore. you've also got to combine that with the high temperatures. looking at well over 100 degrees in the area, and real low humidity. you're dealing with stuff that's at a critical level fuelwise. anything sets it off. >> pam, thanks for your time. it's like a tinderbox because of these dry conditions. as we continue with this shot from sky 7 here. she was talking a little bit about the weather conditions. let's get an update from spencer christian. it's true the wind is not strong right now. you can see near the fire, there's drafts at the base of the fire that might be heavier. we're looking at a temperature reading right now, in clayton, of 104 degrees, relative humidity, only 14%. that is dangerously low. while the wind is generally calm, we've seen gusts between 5 and 10 miles per hour. overnight, it's mild throughout the entire region. there won't be a cooldown overnight. tomorrow, quite warm to hot once

again. highs of 63 in half moon bay. 63 in san francisco. inland over the hills, 94 the expected high in walnut creek tomorrow. 97, perhaps higher near antioch. here's the accuweather seven-day forecast. one more day of hot weather inland tomorrow. the heat will ease up a bit on friday, not a lot though. high temperatures in the areas will drop down -- or reach up to only about 90 degrees over the weekend. cooler weather over the weekend, but high fire danger the next couple days. >> here are the other stories making headlines at 4:30. 2 suspected bart killer was formally charged with murder this morning. the charges were announced against john cowell against nia wilson. she was stabbed to death at the mcarthur bart station on sunday. melanie woodrow posted this video of nia wilson's mom saying she wants justice for her baby. david louie tweets whoever just
