WARNING: Extreme High Tides, High Surf, Winds, Flooding Likely

SAN FRANCISCO (CBS SF) -- The first set of "extreme high tides" is expected to impact the region's coastal areas Tuesday morning, which may cause flooding in Marin County and other areas, according to the U.S. Coast Guard.

Coast Guard officials said a mixture of forecasted colder temperatures, strong winds and precipitation may serve as impetus for a potentially dangerous tidal situation, which the National Weather Service expects to last through Thursday.

Combined with rainwater runoff, strong onshore winds and larger surf, the high tides are likely to cause flooding of Marin County's coast as well as low-lying areas around San Francisco and Monterey bays, Coast Guard officials said.

Some of the affected areas could apparently include beaches, low-lying roads, trails, docks harbors and tidal flats.

"We encourage all persons on or around the coast to remain especially cautions during this storm system," Andrew Cohen, command duty officer at the Coast Guard's San Francisco sector, said in a statement.

"We stand ready to respond if boaters and beachgoers find themselves in distress," Cohen added.
