An intense frontal rain band will sweep through the Bay Area region Friday afternoon through the night, followed by showers and thunderstorms through Saturday morning, according to the National Weather Service.

The rain swell will build through Friday evening and into Saturday morning, prompting the weather service to issue coastal flood and high surf warnings until 2 p.m. Saturday. Major river, creek, stream and coastal flooding is possible in the North Bay and Peninsula on Friday and Saturday, the weather service said.

Moderate flooding is possible Friday in the East and South Bay, with minor flooding possible on Saturday. Santa Cruz and Monterey counties were the hardest hit locally by flooding and swells on Thursday and will again face major flooding in rivers, creek, streams and coasts both Friday and Saturday.

Major rain and thunderstorms could be seen in the North Bay, Peninsula, Santa Cruz and Monterey counties on Friday and Saturday, with moderate storms possible in the East and South Bay on Friday and minor storm activity on Saturday.

The weather service said that hazardous conditions may exist Sunday due to debris from storms and reminded residents to stay off piers, jetties and rocks during high surf.
