South Bay Braces For Heavy Rain: NWS

SANTA CLARA COUNTY, CA – A major storm is approaching the Bay Area, and it’s expected to unload on the South Bay.

The storm is expected to arrive late Wednesday with heavy rainfall expected throughout the Bay Area Thursday and into Friday, the National Weather Service said.

Parts of the Bay Area are expected to see up to three inches of the wet stuff, according to the agency’s latest forecasting models.

Most of the Bay Area will see between 1 ½ to 2 inches of rain, NWS Meteorologist Matt Mehle told Patch.

“The Mount Tamalpais area could see” up to three inches, Mehle said, noting the area tends to be a precipitation “overperformer.”

The heaviest rains in Marin are expected to fall between 10 a.m. and 1 p.m. Thursday, but the rest of the Bay Area is a different story, Mehle said.

The South Bay isn’t expected to see the heaviest rains until hours later, likely during the evening commute, Mehle said.

Despite frigid temperatures expected later this week, snow is unlikely to fall on Mount Tamalpais this week, but some Bay Area locations at higher elevations could see some frozen precipitation, Mehle said.

The NWS forecast for the greater San Francisco Bay Area calls for cool but sunny conditions Tuesday, with freezing temperatures possible inland. Daytime highs are expected in the 50s.

Overnight lows will range from the mid 40s and upper 30s around the bay and are expected to dip into the mid to lower 30s in the inland areas of the East Bay and North Bay.

An additional storm could arrive this weekend, but the NWS hasn’t yet determined the timing or rainfall estimates.
