'Dangerously Hot' Weather Warning For Walnut Creek

WALNUT CREEK, CA — An excessive heat warning has been issued for Walnut Creek and much of the Bay Area this weekend. The National Weather Service cautions that daytime temperatures here could range from 102 to 110 degrees.

The warning will be in effect from noon Friday through 10 p.m. Sunday.

Parts of Alameda, Contra Costa, Marin, Napa, Santa Clara, Solano and Sonoma counties are included in the warning, the National Weather Service said Thursday.

Areas immediately fronting the coast or bay should see lower temperatures and are not included in the warning.

Temperatures were expected to begin warming Thursday, the weather service said.

"Take it easy if you're spending time outdoors in peak heat and drink plenty of fluids," the weather service said.

Dangerously hot conditions are likely across the interior beginning Friday and continuing into the weekend as daytime temperatures warm to between 102°-110°F. Thus, an Excessive Heat Warning has been issued. Onshore flow should limit heating near the coast/bays. #CAwx #CAHeat pic.twitter.com/AUoe0Qwdqb

Bay Area residents can likely expect some reprieve from the heat Sunday. Cooling is expected to continue into early next week, the weather service said.

Officials warned residents to be wary of heat exhaustion or heat stroke after spending prolonged time outdoors. People are especially vulnerable if they must spend a lot of time outside, don't have air conditioning, are older, are a young child or have chronic ailments, the weather service said.

Drink lots of water, stay out of the sun, and stay in air conditioning, the weather service said. Keep an eye on family members and neighbors.

Call 911 and immediately move into the shade if you are experiencing a heat-related illness.
