An atmospheric river brought additional rain, strong winds, and flooding to the Bay Area Tuesday, with an increasing chance of thunderstorms later in the afternoon.

The storm is expected to continue to favor the North Bay, resulting in 2.5 to 3 inches of additional rain in Sonoma County and 3 to 5 inches of rain in the North Bay mountains. A flood watch is now in effect for most of the Bay Area and Central Coast through 4 a.m. Wednesday.
