had burned 8,000 acres, but it's since more than doubled in size to 22,000 acres. fire is spreading smoke across the bay area. there are mandatory evacuations in place for parts of yolo county. the fire is burning near the community of gwenda, areas in napa county are now under advisory evacuation orders means folks could be told to leave homes at any moment. some under evacuation orders wait until the last minute, though, doing all they can to ensure their homes remain standing. firefighters say with this erratic fires, delaying evacuations is not the best idea. >> yeah. fire break around that fence, and -- but, when you get a fire this bad, that's not a lot that's going to stop it. >> people get a false sense of safety because they have the sensible space, but when the fire starts spotting a half mile, a mile away, winds pick

up, and then, you know, nobody's safe. >> we are bringing in scott mcclain on the phone, deputy chief with cal fire. scott, thank you so much for joining us. we want to ask, what's the biggest issue facing firefighters? we understand the winds shifted at this point? >> caller: right. last weekend, we had the same weather, north winds pushing the fires last week at 20 miles per hour. this week, started early, started friday, but triple digit figures, low humidity, the terrain is horrible, and then couple that with the winds that are pushing it from the north, and as you said, i got reports a few minutes ago the winds originally were coming in northeast and changed coming southwest, so that's been a flip. when we deal with that or see that, that causes that fire behavior just to become extremely unsafe and extremelier rattic. >> right. can you tell us if buildings are threatened? >> caller: a few. keep in mind, this is a very

rural area where the fire's being pushed. there's a lot of ranches out there, several homes, but not as much as we've seen in the previous fires. >> scott, thank you so much. we wish you and your firefighters the best of luck during this very tough situation. thank you so much for joining us. it is not just smoke, ash drifting down into bay area is also a problem. nbc bay area is live in solano county with more. >> reporter: well, you know, we have not smelled smoke all day, but certainly saw it in different parts of the bay areas. it's sort of a smoke and ash coming down, and you can wipe it ra off of cars and see that brown-orange glow, and now a smoke advisory has been issued. crossing the bay bridge, the impacts of the fire are easy to see. >> northerly winds blow narrow bands of smoke high above the fog and the ashes, falling out from the overhead smoke. >> reporter: sarah is with the

bay area air quality management district that issued the smoke advisory. she says people may want to play it safe. >> it is recommended that residents impacted by the smoke seek shelter in buildings or move outside the smoke impacted area. >> reporter: elderly people, children, and people with respiratory conditions, take extra precautions. in san francisco, the ash was noticeable. martha rose picked up a mask just in case. >> it was gray. and then i noticed it was all over the yard, not just the neighbor's yards, and then i realized what it was. >> reporter: same in berkley where ash covered cars. >> i just staw ash come down lie rain a moment ago, but what i noticed more than anything is the light. i did look up, and i saw there was some fire in yolo county. >> reporter: the air district said readings today showed good to moderate, but it's believed that smoke may be bypassing monitors because it's a narrow band, and they keep watching.

>> we are watching monitors throughout the day to see how they register particlate matter levels, which we are most concerned about from the fires. >> reporter: now, according to the air district, conditions could improve on tuesday and wednesday, and as the winds shift directions and they say that could push much of this smoke out of the bay area. reporting live in solano county, nbc bay area news. >> thank you so much for that report. the hazy conditions, at times, concerning, but also made for an incredible sunset last night. this is a live look at the san mateo bridge. hazy right now. conditions are not as bad as they were this morning. again, you can still see that haze. we are tracking the conditions. >> hi. as you heard from deputy chief of cal fire, the winds have shifted. originally northerly winds, now

and it's already getting smoke in parts of the area. this is a shot of walnut creek. there's light to orange hues, and you noticed last night that orange sunset. the reason for that is back of the smoke. you can see this is where those yolo county fires are burning. you see the plume of smoke going down as far as the san francisco area. it was a lot more noticeable overnight and during the day. several people tweeted me and tagged me in photos of ash on the vehicles, but there's going to be a shift in the wind. they were normal therly and nowy are beginning south blowing smoke into the sacramento area. despite that, the smoke advisory is in effect, but air quality remains moderate because of that smoke and ark, and in the so sous -- south bay is it's fairly okay because a lot of that smoke is in the higher elevation area.

regardless, if you can filly see the smoke, you know, close all the windows out, and take precautions. i do want to show you current conditions of the active wildfires burning nearby. the pawnee fire in lake county, 101 degrees, current conditions right now. as i mentioned, southwesterly winds now blowing, and that's going to kind of take part overnight. the good thing is, it looks like some of the winds will be calming down, just a bit, into the overnight hours, temperatures will drop into the 70s for the pawnee fire area. coupe fire, yolo county, 101 degrees now. the humid ity at 14%, and overnight, humidity as well, and the temperatures, again, dropping down into the 70s. however, a nice onshore flow is showing a significant drop in temperature. look at this. ranging in drops upwards of 20 degrees in some spots in the bay area, and this is what's going to set us up for a much cool ee

>> extrapolate that to the potential billions of mobile devices that are out there, that's a pretty staggering number. >> reporter: perhaps, 15 million infected devices in the u.s. alone. it's a clever strategy. instead of using their own computering powers to run illicit powers that crack passwords, steal gift cards, scoop up tickets, and post spam on social media, there's bahts to commit crimes. >> you make requests while it's in your pocket. they have no idea it's happening. >> reporter: the strategic bots minimize red flags, hidesing in the background, keeping you in the dark. they use your phone only about 50 times per day. you don't notice the extra data use. they time exploits while you are moving, when your phone's ip address is changing, and it hits different cell towers, making it tougher to track. >> it's another one of those techniques where the bot

operators are trying to hide and escalating the problem, and it's a problem that's going to be very difficult to solve. >> reporter: how do the bots get on to the phones? often, we let them on. they say malicious web links or attachments open the door to malware that install bots behind the scenes, invisible to you. >> far more vulnerable to an attack than most people realize. >> reporter: this chief strategy office from lookout in san francisco, helping people protect mobile phones. it contends mobile phishing is the biggest unsolved problem in cyber security. he gave us four steps to prevent this, including bots. one, set a a passcode. it's shocking how many people don't. two, turn on auto updates because bad guys exploit bugs in old softwares. three, install apps from the official store, never from links, and, four, consider buying security software for your phone.
