The National Meteorological Service improved the fire weather watch issued yesterday as a red flag warning for much of the Bay Area, including the North Bay Hills, due to dry north winds off shore which are expected to arrive at 11 p.m. Sunday evening. The initial gust of winds will occur while the humidity values ​​remain fairly humid. However, the dry offshore winds will begin a rapid drying of the atmosphere with humidity values ​​rapidly decreasing by Monday morning.

As a result, PG&E is expected to proactively cut power to parts of Sonoma County, including some Sonoma Valley customers, on Monday, September 20. At this time, it looks like the city of Sonoma will not be affected. Find an address on the PG&E power outage map to see if a particular location is included in this planned power outage.

PG&E has indicated that the exact time to power off and restore is subject to change depending on weather conditions. Please refer to PG&E PSPS Updates Page for the most recent fault maps, estimated downtime and power restoration information.


City offices, water facilities and the Sonoma Police Department are not expected to lose power and will be open during normal hours.


PG&E will open a CRC in the Sonoma Valley. The Community Resource Center is scheduled to be open Monday, September 20 and Tuesday, September 21 from 8:00 p.m. to 10:00 p.m. All community resource centers follow state and county guidelines for fighting COVID-19.

  • Sonoma First Congregational Church (exterior only), 252 West Spain Street, Sonoma. Blankets, snacks and water, device recharging, ADA accessible toilets and washing station, seats, small medical device recharging, Wi-Fi


The National Meteorological Service issued a Red flag warning for parts of the Bay Area, including the North Bay Interior Mountains, from 11:00 p.m. Sunday (9/19) to 8:00 p.m. Monday (9/20). A red flag warning is issued for weather events that may result in extreme fire behavior. A red flag warning is the highest alert. During these times, extreme caution is recommended by all residents, as a simple spark can cause a major forest fire. Learn more about CALIBRATE THE FIRE.

The Sonoma Valley Fire District increased daily staffing in the event of a critical fire.


While we would not expect there to be traffic lights within Sonoma city limits, drivers are reminded to be vigilant as several intersections in Sonoma County may be without power, including included during traditional travel times. Public safety officials are urging drivers to reduce their speed, drive carefully, and treat all intersections without electricity as a four-lane stop, according to state law.
