Freeze Warning Issued For Napa Valley, North Bay

NAPA VALLEY, CA — Officials with the National Weather Service San Francisco Bay Area issued a freeze warning for early Tuesday morning for the interior valleys of the North Bay.

According to the weather service, the freeze warning is from 3 a.m. to 9 a.m. Tuesday for residents of communities within the interior valleys of the North Bay, including the cities of Santa Rosa, Napa, San Rafael, Petaluma, Novato and Rohnert Park.

Temperatures from the mid-20s to 30 degrees were forecast overnight Monday into Tuesday.

A temperature of 31 degrees was forecast for Napa.

Frost and freeze conditions will kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing, the weather service said.

The weather service advises residents to take steps now to protect tender plants from the cold.

To prevent freezing and possible bursting of outdoor water pipes, they should be wrapped, drained, or allowed to drip slowly.

Those who have in-ground sprinkler systems should drain them, and cover above-ground pipes to protect them from freezing.

Ensure all animals have a warm and dry shelter.

Public health officials recommend residents limit their time outdoors during a freeze warning, as serious medical conditions including hypothermia and frostbite can develop with prolonged cold weather exposure.

Hypothermia and frostbite are both dangerous conditions that can occur when a person is exposed to extremely low temperatures. Those most at risk include older adults with inadequate food, clothing or heating.
