The National Weather Service has issued a red flag warning for parts of Northern California, including the East Bay hills, from 11 p.m. Wednesday to 9 a.m.
Thursday, signaling heightened wildfire danger due to hot, dry, and windy conditions. Temperatures are expected to reach around 90 degrees Fahrenheit, with wind gusts up to 30 mph.
Residents in the affected areas are urged to be prepared to take immediate action if a fire ignites.
In response to the elevated fire risk, Pacific Gas and Electric Company (PG&E) has notified customers of a possible Public Safety Power Shutoff (PSPS) in portions of Sonoma, Napa, and Solano counties. The potential shutoff could begin Wednesday night and last through Thursday afternoon, as the utility aims to prevent power lines from sparking wildfires during extreme weather.
Meanwhile, the largest active fire in California is burning near Lake Berryessa. The Putah Fire, which started Monday, had consumed 869 acres as of Tuesday night.
Highway 128, which had been closed for more than a day due to the fire, has since reopened. Firefighters continue to work to contain the blaze, and authorities are monitoring conditions closely.
The red flag warning covers areas shown in red on weather maps, including the East Bay hills and parts of the North Bay. The combination of high temperatures, low humidity, and gusty winds creates critical fire weather conditions.
Officials advise residents to have an emergency plan and supplies ready, and to stay informed through local alerts and news updates.
