PG&E's 7 day potential psps forecast

The City of Sonoma is preparing to respond to the impacts of a possible power shutoff conducted by PG&E, a Red Flag Warning and High Wind Advisory expected to arrive Saturday, October 26th and last through Monday, October 28th.

Red Flag Warning


The National Weather Service has issued a Red Flag Warning and High Wind Advisory for the North and East Bay Hills and Valleys (8 PM Sat-11 AM Mon). Confidence is high for dangerously strong offshore winds and critically low relative humidity. This event looks to be the strongest since the 2017 North Bay Fires given the strength and duration of the winds. Strongest winds expected Saturday night into Sunday morning. Stronger winds mixing down to the lower elevations will be a particular concern throughout Sunday. Winds will gradually ease Sunday evening, but remain locally gusty across higher elevations into Monday morning.

High Wind ThreatResidents are encouraged to prepare for high winds beginning Saturday, October 26th. High winds can cause downed trees and power lines and flying debris.  The safest place to be during high winds is indoors.  If you are caught outside during high winds, take cover next to a building or under a shelter.  Watch for flying debris.  Tree limbs may break and loose objects may fall.

In advance of any wind event, be sure your property is secure. Remove any dead trees or overhanging branches near structures, loose roofing materials and objects in yards, patios, roofs or balconies that could blow away. Bring in unsecured objects from patios and balconies and secure outdoor objects such as lawn furniture or garbage cans that could blow away and cause damage or injury.  Postpone outdoor activities if a wind advisory or high wind warning has been issued.
