Flooding is possible on roads, streams and creeks. The Level 2 storm will bring light to moderate rain to other parts of the Bay Area.

The storm is prompting a a Winter Storm Warning for the Sierra. It starts tomorrow afternoon and stays up through Wednesday night. High clouds will continue to stream in overnight, but they will not prevent the temperatures from dropping.
