San Francisco broke a daily record for rain that had been in place since 1887 on Tuesday, with a pounding 2.53 inches of rain falling, according to the National Weather Service. The rain was so heavy at times that it fell in almost white vertical sheets, quickly overwhelming storm drains in some areas.

The NWS says excessive rainfall is expected to cause flooding along the Russian River, affecting roadways and agricultural land.

Days after an atmospheric river brought record-setting rainfall to California, the state is in the crosshairs of another rainy storm system.
