Creeks and streams may rise out of their banks. Low water crossings may become flooded. Flooding may occur in poor drainage and urban areas. * ADDITIONAL DETAILS... - Multiple rounds of moderate to heavy rainfall are expected across the North Bay through Friday evening. An additional 2-4" is possible over the North Bay Mountains and 1-3" over the North Bay Valleys by Friday. Nuisance flooding will increase through Friday with rises in smaller creeks and minor flooding along some of the mainstream rivers (Russian River, Napa River). Debris flows are possible particularly for the Pickett Burn Scar. - http://www.weather.gov/safety/flood PRECAUTIONARY/PREPAREDNESS ACTIONS...

There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF COASTAL CALIFORNIA AND PORTIONS OF THE CENTRAL VALLEY SUMMARY An isolated risk for severe gusts/localized wind damage and perhaps a brief tornado will be possible today into this evening along much of the California Coast and portions of the Central Valley. California Recent satellite imagery shows a mid/upper-level low over the eastern Pacific and a negative-tilt shortwave trough moving northward along the northern CA and OR Coast. An upstream mid-level jet and associated vorticity maximum will move through the base of the eastern Pacific upper low/trough and approach the San Francisco Bay and northern CA vicinity this evening. Strong to locally severe thunderstorms capable of producing mainly isolated severe/damaging winds will remain possible with convection today into this evening. Weak instability is forecast to persist across much of coastal CA into the Central Valley, with cool surface temperatures, saturated profiles, and modest lapse rates aloft (reference the 12Z OAK sounding) limiting the development of greater MUCAPE. Still, a favorable kinematic environment with enhanced west-southwesterly mid/upper-level flow will conditionally support occasional strong to severe convection, contingent on sufficiently deep/sustained updraft development. Low-level hodographs are forecast to remain enlarged enough to yield a low risk for a brief tornado across much of the Marginal Risk area. Consensus of latest model guidance indicates low/mid-level flow will weaken somewhat this afternoon before gradually re-intensifying this evening as the next embedded shortwave trough and associated mid-level jet overspread coastal northern/central CA. A mix of linear bands and cellular convective structures may continue to pose an intermittent risk for isolated damaging gusts and perhaps a brief tornado into this evening/tonight, before the severe threat gradually diminishes towards 12Z early Friday morning.
