Heres our live camera in san jose with mostly cloudy skies. But things will be changing. Look what happens about an hour during the 6 00 to 7 00 hour. The coverage will be increasing over the next hour or so. We could have thunderstorms moving quickly across the bay area by 9 00. Another system approaches the area thursday night and maybe more rain in your fiveday forecast. More on that in a few minutes. Every time it rains this winter, its going to cause concerns for many homeowners in the north bay, especially in the burn zones where is the potential for flooding and mudslides. Its been nearly three months now since those Deadly Wildfires broke out and many people have started to rebuild. Ktvus tom vacar joins us live from santa rosa with more. Reporter when this santa rosa hillside neighborhood burned down, the other thing that burned off was all of the cover. And now this is just naked ground laying out here and any kind of water can start the land moving. Now, a lot of water could do some real make problems and all day today theres been almost no rain up here. But no that it is coming and thats what they are worried about because of what they are what they are trying to do is to dodge a weather bullet. Reporter rain wasnt an issue until half past noon when the first light rain started falling in santa rosas coffey park, rains that stayed light for the afternoon. The worry in Sonoma County and napa that serious rain falling on denuded hillsides and burnedout lots could start mudslides, floods, perhaps even landslides. At napa valley expo, crews handed out wattles to help folks stabilize their lands. We are up on a steep slope. Our house has been removed. The foundations are gone. Theres a lot of exposed dirt work and stuff that usually protected it from getting too wet. We already got around the foundation yesterday. Today we are putting it in the drainage channels and stuff, finishing up areas where ash and debris will go down into drainage. Just trying to do our part. Reporter back in Sonoma County the worst danger is to those residences, wineries, businesses and Youth Authority facility at the foot of Hood Mountain regional park. The mountain is so denuded of vegetation and so unstable and steep, the park is closed indefinitely and signs proclaim the extreme danger to those close by. There are plenty of drains around this mountain that can easily handle normal or torrential rains provided that the trees and the brush and the grass are still up there which they are not anymore. And the problem is, if you start getting major flows of mud and landslides, these drainages will be overwhelmed. In santa rosa, the state Emergency Services director touring the area with the u. S. Homeland security secretary was grateful for the mostly light rain, saying a lot of reparations are already in place. Right after the fires went out, one of the key priorities was mitigation efforts, clear channels, put in these wattles, these, um, these devices to help to, um, channel and offset water flows. A tremendous amount of mitigation has been done. Reporter so while tonights rains are not likely to produce any big problems, people are going to be concerned about this every rain event throughout the winter and into the spring because its going to take at least that long for all of this land to at least start growing back some stuff. A lot of grass has been planted but theres still plenty to plant. They are not taking any chances. Tom vacar, ktvu fox 2 news. Thank you.
