Cold and windy conditions are descending on the region, bringing overnight freezes, strong wind gusts and high surf, according to a revised forecast issued Monday night by the National Weather Service that extends a freeze watch to much of the Bay Area.
The update also includes a forecast for rain on Friday.
A wind advisory is currently in effect through 6 a.m. Tuesday for the region's coastline north of Santa Cruz, with winds of 20-30 mph and gusts up to 50 mph. To the south, the advisory lasts until 7 p.m. Tuesday on the coast of Monterey County.
A freeze warning was issued for much of the Bay Area from 2-9 a.m. Wednesday, with lows expected in the 20s and 30s in some areas.
Forecasters revised their initial forecast Monday morning, which had called for freezes to be isolated to the interior valleys.
People who are unsheltered and marginally sheltered will be at risk, weather officials said.
The low temperatures could kill crops and other vegetation and damage unprotected outdoor plumbing.
Residents are urged to start now to protect plants and outdoor water pipes. Pipes should be wrapped and drained or allowed to drip slowly.
People with in-ground sprinkler systems should drain the systems and cover above-ground pipes.
