Learn the role weather plays in a power shutoff


If weather forecasts indicate gusty winds and dry conditions, combined with a heightened fire risk, it may be necessary for us to turn off the electricity serving that area. This is called a Public Safety Power Shutoff (PSPS).

Conditions affecting a possible PSPS event can change quickly and the actual impact of a future PSPS event is uncertain.

NOTE: This forecast is based on weather conditions and fuel moisture content only and does not include other criteria used to determine whether a PSPS may be necessary.

No Public Safety Power Shutoff (PSPS) events are anticipated for the next seven days. Fair and dry weather is expected today for most of the PG&E territory except for northern Humboldt where the next weather system will spread another round of rain late this afternoon and evening. Those rain showers, mostly light, should then spread south and eastward overnight and during the day tomorrow into the Bay Area and northern San Joaquin Valley with the precipitation spreading a bit farther southward into early Thursday across the Sierra where a light dusting of snow is possible over the highest peaks. Continued dry weather is forecast for the southern part of the territory. Fair and warmer weather is then expected to return by the end of the week and into next weekend with light offshore winds across the central and northern part of the state. Another weather system may then produce shower activity across the northern part of the state and Sierra Sunday and into next Monday with dry weather expected elsewhere. Breezy to gusty offshore winds may then develop early next week and these winds will be watched closely for an increase in strength. Overall, fine grass fuels are cured below 5500 – 6000’ and live fuel moistures remain near or below critical levels, but precipitation this week will increase dead fuel moisture levels across the northern areas.     
   

Please note: This forecast is published daily by an operational meteorologist from PG&E’s Meteorology and Analytics team. This forecast has been customized for PG&E utility operations and should not be used for any other purpose or by any other entity. This forecast only provides a broad overview for a potential Public Safety Power Shutoff (PSPS) event in the next 7 days as determined from an analysis of forecasted weather, the potential for wind-related damage, and fuel moisture content in dead and live vegetation. It is not a fire danger forecast. The forecast is broken down by broad PG&E Geographic Zones numbered 1 - 9; however, PSPS decisions are made at more granular levels; thus, only a portion of a zone may experience a PSPS event. While a PSPS event may not be expected for an area, due to the interconnectivity of the grid any location within PG&E territory may be subject to PSPS event.

Information is provided by weather stations or cameras throughout PG&E’s service territory. Note that weather stations vary in the type of information collected (i.e., one may report wind only, while another may report humidity, temperature, wind speed and more). Also, each weather station includes its own information timestamp.
