The National Weather Service is cautioning residents about potential heat risks and fire danger for the weekend. The areas of most concern will be high terrain spots of northern and eastern Napa and Sonoma, as well as throughout the Diablo Range.
“Temperatures in the mid to upper 90s as well as isolated triple digit readings are expected on Saturday which will exacerbate existing severe fire weather conditions due to gusty north winds and low humidities,” reports NWS.
A heat advisory has been issued for Saturday for most of the Bay Area, which will remain in effect from 11 a.m.until 8 p.m.
The agency also warns that blazes could spread rapidly—in October, wildfires spread across Northern California, causing billions in damage and the loss of dozens of lives—and urges residents against outdoor burning or other activities (e.g., barbecuing) that may lead to fire.
While today’s weather in San Francisco started out cool, temperatures around the city and throughout the Bay Area will rise as the weekend nears. People are asked to remained hydrated and to look after pets, children, and the elderly.
