The information in this map is intended only to provide customers with a general estimate regarding potential locations that may be impacted by a PSPS event should one become necessary. Conditions affecting a possible PSPS event can change quickly and the actual impact of a future PSPS event is uncertain.
Wednesday, May 21, 2025
NOTE: This forecast is based on weather conditions and fuel moisture content only. It does not include other criteria used to determine whether a PSPS may be necessary. This forecast only provides a broad overview for a potential PSPS event in the next 7 days. It is determined from an analysis of forecast 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 county. PSPS decisions are made at more granular levels. Only a portion of a county 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.
No Public Safety Power Shutoff (PSPS) events are planned for the next week. Fair and dry conditions continue today with warming temperatures. The sea breeze will keep temperatures near the coast seasonable with daytime highs reaching the 70s to 80s across the coastal and interior valleys and upper 80s to 90s across the interior. Periods of breezy northwesterly winds and slightly cooler temperatures are expected tomorrow and Friday as two weak weather systems pass through the region. Fire potential will increase across the interior tomorrow, mainly through the San Joaquin Valley, as breezy winds combine with decreasing relative humidity values. Temperatures across the interior may warm back to above average over the weekend as high pressure briefly builds across the territory.
Fuels: The annual grass crop is transitioning from live to dead across the territory, with more advanced curing farther south. Meanwhile, live fuel moisture values are near peak annual moisture content across lower elevations and beginning to increase in higher elevations. Dead fuel moisture values will decrease slightly over the next couple of days as warmer weather develops and are generally trending close to normal for this time of year. The latest 4 Month Seasonal Outlook from Northern Operations Predictive Services is forecasting normal fire activity across Northern California for May, and near to above-normal fire activity June through August for areas away from the coast. Southern Operations Predictive Services is forecasting near normal to slightly above normal fire activity for the South Coast area in June and in the interior locations during July and August.
There are 675 of 788 circuits in High Fire Risk Areas (HFRA) that are EPSS-enabled today. The remaining 113 circuits in HFRA will have devices postured in normal settings due to low FPI ratings. Additionally, 4 EPSS Buffer-only circuits are enabled today.
