NORTH STATE, California – Some Pacific Gas and Electric customers in the Northstate may experience a Public Safety Power Shutoff (PSPS) with drier and windier weather expected by the end of the week.

As of Tuesday, PG&E’s website says no PSPS is expected on Tuesday or Wednesday. However, there is an increased risk of a PSPS on Thursday for 12 counties, including Colusa, Glenn, Mendocino, Shasta and Tehama counties.

On Friday and Saturday, the list more than doubled to 30 counties, with the addition of Butte and Plumas counties. The list was narrowed to 20 counties on Saturday, possibly including Butte, Colusa, Glenn, Mendocino, Plumas, Shasta and Tehama counties.

The utility says specific addresses, maps and other closure information are typically available two days before the closure. Click here for more information about areas that may be affected by the PSPS.

PG&E plans a PSPS when there is a chance that severe weather conditions, such as high winds, could cause a tree or debris to damage equipment and start a dry vegetation fire. Criteria include low humidity, forecast high winds, dry material on the ground, vegetation near power lines, a red flag warning from the National Weather Service or otherwise real-time observations from ground crews and weather experts.
