Weather Awareness – Red Flag Warning for North Bay Hills 11 PM Wed. – 11 AM Thurs.

Posted on September 29, 2021


The National Weather Service has issued a Red Flag Warning for gusty north to northeast winds and low humidity, which is in effect from 11 PM this evening (9/29) to 11 AM (9/30) Thursday for North Bay Mountains focused on the Vaca and Mayacamas ranges in Napa County and including the border area of Sonoma and Napa counties.

Wind speeds of 15 to 25 mph with gusts up to 35 mph are possible. Read the full warning from the National Weather Service. Any fire starts would likely see rapid spread due to dry fuels, low humidity and gusty winds in areas that did not receive wetting rains over the weekend.

PG&E has not announced any potential Public Safety Power Shutoffs at this time. As always, please make sure that you are signed up for SoCo & Nixle alerts and are prepared in case of an emergency, learn more on our Emergency Preparedness page.
