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.

An “impressive” atmospheric river is set to deliver numerous rounds of moderate to heavy rainfall across the Bay Area this week.

Four school districts in Sonoma County will be closed Wednesday due to flooding, the Sonoma County Office of Education said. Closed will be all schools in the Guerneville, West Sonoma County Union, Monte Rio Union school districts and Kashia Elementary,
