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.

In Sonoma County, Green Valley Creek at Martinelli Road has reached a moderate flood stage, and the Russian River at Guerneville is expected to have minor flooding by Wednesday morning. Flooding in the North Bay is expected to continue throughout the day, the weather service said.

Heavy rain is hitting the Bay Area and coastal areas this week as an atmospheric river moves through Northern California.
