MENDOCINO Co., 6/28/23 — After unseasonably cool temperatures, Mendocino County will experience its first heat wave of the year this holiday weekend. The National Weather Service is forecasting temperatures to rise significantly across Northern California, reaching over 100 degrees in parts of eastern interior Mendocino County and portions of Lake County. Here’s an overview of what’s to come with additional resources at the end of the article.
The extreme heat increases the likelihood of heat related illnesses, especially for those working or participating in outdoor activities, as well as the young, elderly, pets, and plants. We have a list of tips and resources at the bottom of this article on how to be safe during heat waves.
The National Weather Service Eureka (NWS Eureka) has issued an excessive heat watch for northeastern Mendocino County, including Covelo, and the entirety of Lake County. The watch is in effect from 1 p.m. Fri. June 30 through 9 p.m. Sun. July 2. An excessive heat watch is issued when conditions are favorable for an excessive heat event in the next 24 to 72 hours.
According to NWS Eureka, the areas under the watch may experience “dangerously hot conditions with temperatures up to 106 degrees possible.” Covelo will experience triple digit temperatures ranging from 101 degrees starting on Thursday to 104 degrees on Sunday with overnight temperatures averaging in the low 60s. If you plan to head over to Blue Lakes, Clear Lake or Lake Mendocino, expect high temperatures in the low 100s.
NWS Eureka has also issued a heat advisory for southeastern interior Mendocino County, including Ukiah and Hopland, from 1 p.m. to 8 p.m. Sat. July 1. These communities will experience temperatures in the 100s, with Saturday forecast as the hottest day atf 106 degrees. On that note, it’s likely many interior residents will flock to the Mendocino Coast to enjoy nature’s air conditioning. Fort Bragg can expect sunny and cool weather in the low 60s.
Mendocino County Public Health has not opened cooling stations as of publication. Additionally, PG&E is not anticipating any public safety power shut offs. We will update this article if that changes.
