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 atmospheric river from the north that made its first push into the Bay Area over the weekend got its second wind Monday night, “over-performing” the National Weather Service’s expectations, the agency said. The storm, which is “stronger than expected,” caused minor to moderate flooding in some areas.

The National Weather Service said this week's atmospheric river is proving to be stronger than initially expected.
