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, January 11, 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 meteorology is closely monitoring a potential Santa Ana wind event across Southern California from Monday morning through midweek, which could bring elevated fire weather conditions to the Tehachapi Mountains and Grapevine area. The updated PSPS Potential forecast now shows Kern County in PSPS Watch for Monday and Tuesday due to gusty winds and low humidity. Elsewhere, a weather system will continue to migrate into the Great Basin today resulting in breezy to locally gusty offshore winds, 15-30 mph with gusts in the 30-40 mph range, across the northern interior and Bay Area through tomorrow morning. Fair and dry weather will continue into early next week under persistent offshore flow with lighter winds expected across the North tomorrow followed by another round of breezy to locally gusty winds on Monday. Across the far South, gusty east-southeast winds are forecast to strengthen along the Tehachapi Range during the Monday morning timeframe and continue through the day with a chance for winds to mix into lower elevation foothills. Winds are expected to weaken Monday evening across lower elevations but will likely remain gusty across higher terrain through Tuesday and possibly into Wednesday before diminishing during the latter half of the week.
Fuels: New growth of the annual grass crop is occurring for many areas in the central and northern part of the territory. However, live fuel moisture values will remain seasonably low as brush is in winter dormancy. Dead fuel moisture varies across the territory, with higher values in the North where precipitation is ample, but much lower across the South where precipitation has been more lacking. Recent dry, offshore wind events have lowered dead fuel moisture values across portions of the far South. The latest 4 Month Seasonal Outlook from Northern Operations Predictive Services is forecasting normal fire activity from January through April. Southern Operations Predictive Services is forecasting above normal fire activity for the South Coast area until significant precipitation occurs, with normal fire activity elsewhere.
There are 27 of 788 circuits in High Fire Risk Areas (HFRA) that are EPSS-enabled today. The remaining 761 circuits in HFRA will have devices postured in normal settings due to low FPI rating. Additionally, 2 EPSS Buffer-only circuits are enabled today.
