PACIFICA, Calif. (KTVU) - The Coast Guard issued a warning about the heavy winds and high surf forecast for Bay Area coastline through Friday.
Waves from 12-25 feet are expected in the area, including Pacifica, as well as dangerous rip currents and potential beach erosion.
But by Wednesday night heavy rain prompted the National Weather Service to issue an Urban Flood Advisory until 11:30 p.m. for parts of the Bay including San Francisco, Oakland, and to the north with places like San Rafael affected.

In San Francisco, Twitter user Joey Hodges showed a flooded Market and Church where vehicles were still going through the water logged-roadway.
NWS advised not to drive over the roadways and to report flooding to local law enforcement.
“It’s important that the public take these advisories seriously and not place themselves or their families and friends in dangerous situations,” Joseph Ford, a Coast Guard sector San Francisco command center watch officer, said in a statement. “We strongly urge people to stay away from breaking surf and to never turn your back on the ocean, as waves can be unpredictable.”
Boaters should always have a marine VHF radio and life jackets for everyone aboard, the Coast Guard recommended. Life jackets should be worn at all times when underway.
