Willits, CA – The National Weather Service in Eureka has issued a Frost Advisory for the northeastern and northwestern Mendocino interior, including Covelo, Willits, and Laytonville, effective from 2 a.m. to 9 a.m. PDT Tuesday.
Forecasters expect overnight lows near 33°F, cold enough to cause frost formation across valleys and sheltered areas. The chill could harm sensitive vegetation and unprotected outdoor plants if left uncovered.
This marks one of the first significant frost events of the season for Mendocino County, signaling a turn toward colder late-October mornings. Residents are urged to bring plants indoors, cover outdoor crops, and protect exposed plumbing ahead of the cold snap.
