Temperatures To Plummet As Low As Mid-20s In San Ramon

SAN RAMON, CA — A Freeze Warning and Frost Advisory have been issued for San Ramon and much of the Bay Area for Wednesday morning, when temperatures could fall as low as the upper 20s in interior valleys, according to the National Weather Service.

The warning will be in effect from at 2 a.m. to 9 a.m. Wednesday, the NWS said. The region is also under a frost advisory, which could kill sensitive outdoor vegetation.

Temperatures in San Ramon are expected to hit 33 degrees Wednesday morning, with a wind chill of 27. By Wednesday afternoon temperatures are expected to rise to 58.

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.

The National Weather Service encourages residents to follow the “Four P’s” of cold weather protection:

• People: Wear layers, limit exposure to cold, check heaters in advance.
• Plants: Cover or bring sensitive plants indoors.
• Pets: Bring pets indoors at night and provide them with warmth
• Pipes: Wrap/cover exposed outdoor pipes to prevent freezing.
