Rainy system moves through the Bay Area early Thursday morning

OAKLAND, Calif. (KTVU) - A rainy system moved through the Bay Area pretty rapidly early Thursday morning.

The heavy rain has passed through the area and now there may be scattered showers. 

There is a flood warning at Clear Lake and a Winter Weather Advisory in effect for the Sierra.

Tomorrow Southern California will get a lot of rain - possibly the most they've had since 2010. Friday could also be very windy in the Bay Area.

There will be some rain Saturday morning before a clear day. Sunday night will bring rain in the evening.

Steve says Monday into Tuesday we'll have heavy rain in the forecast.
