Frost Advisory For Walnut Creek: Here's How Cold It May Get

WALNUT CREEK, CA — The National Weather Service issued a frost advisory which is expected to be in effect Sunday morning from midnight until 10 a.m. for much of the Bay Area, including the East Bay Interior Valleys and East Bay Hills.

The National Weather Service is also predicting sub-freezing wind chill temperatures from Sunday into early Monday. Officials recommend that residents limit their time outdoors, as serious medical conditions including hypothermia and frostbite can develop with prolonged cold weather exposure.

In Walnut Creek, low temps were expected to drop to 40 degrees overnight Friday, 34 overnight Saturday and 34 overnight Sunday.

For those who need information on warming shelters in Contra Costa County, dial 211 from a phone and press option 3 to connect with CORE mobile outreach.

According to the National Weather Service, frost and freeze conditions can kill crops and other sensitive vegetation, possibly damage unprotected outdoor plumbing, and create hazardous conditions for livestock and those without adequate heating or shelter.

"People who do not have adequate heating should take steps to find shelter from the cold," the weather service said. "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 that have in-ground sprinkler systems should drain them and cover above-ground pipes to protect them from freezing."
