LIVE: Track rain in San Francisco Bay Area with Live Doppler 7
Heavy rain is expected all day long in the North Bay where flood watches are posted. The focus of flooding will be on smaller streams, creeks and roads. Our rivers will be able to handle this first storm of the season and are not expected to flood.
In the graphic below, areas shaded in red have the highest risk of flooding and those in yellow have an elevated risk.
Rain will arrive before 6 a.m. Wednesday in the North Bay and Flood Watches begin at 4 a.m. Wednesday.
Rainfall totals will range from 2" - 7"+ in the North Bay. Less than an inch of rain is expected for the rest of the Bay Area.
Outside of the North Bay rainfall will be mainly light to moderate with little threat of flooding. However winds will be an issue for many and a wind advisory will be in effect for much of the Bay Area, beginning at 10 p.m. Tuesday. Gusts up to 45mph will bring trees down and isolated power outages.
The rainiest day for the rest of the Bay Area will be Friday.
Like any Atmospheric River, small changes in the track can mean big changes in rainfall totals and impacts.
