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.
Saturday, May 17, 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.
PG&E 7 Day Public Safety Power Shutoff (PSPS) and Enhanced Powerline Safety Settings (EPSS) Potential: Saturday May 17, 2025
No Public Safety Power Shutoff (PSPS) events are planned for the next week. A weather system moving through the region today will lead to breezy to gusty NW winds, scattered showers and thunderstorms in the northern and central Sierra and possibly the Sacramento Valley, and cooler temperatures. Showers and thunderstorms will taper off tonight with dry conditions likely through next week. Dry and breezy northerly winds continue tomorrow and Monday, though likely not quite as strong as today, followed by lighter winds, but warmer temperatures Tuesday through Thursday. Gusty winds along with low relative humidity may lead to elevated fire danger in the Sacramento Valley tomorrow and Monday. High pressure will build over the region next week, leading to lighter winds and warming temperatures. While winds are looking favorable, the warmer temperatures will likely lead to an increase in fire potential next week.
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 increase slightly over the next couple days as cooler 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 657 of 788 circuits in High Fire Risk Areas (HFRA) that are EPSS-enabled today. The remaining 131 circuits in HFRA will have devices postured in normal settings due to low FPI ratings. Additionally, 57 EPSS Buffer-only circuits are enabled today.
