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.
Monday, January 13, 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 continues to monitor a Santa Ana event currently developing across Southern California this morning. The PG&E Emergency Operations Center remains open for a targeted PSPS event in Kern County and the PSPS potential continues to show warning in Kern County through Wednesday.
Moderate to strong Santa Ana winds are occurring this morning across Southern California with gusts in the Tehachapi mountains and Southern California in the 40-50+ mph range. Relative humidity values over elevated terrain in the Tehachapis are in the 20-40% range but expected to decrease into the teens during the day as offshore flow persists. Winds are expected to relax this afternoon and into the evening and we will closely evaluate for opportunities to begin the patrol and restoration process. However, some localized areas of breezy to gusty winds will continue overnight across elevated terrain followed by increasing winds during the day tomorrow and Wednesday. Real-time and the latest forecast data will be utilized to make the all-clear decision to kick off the patrol and restoration process once conditions are safe. Elsewhere, fair and dry weather will continue through the weekend with mild daytime highs and chilly overnight lows.
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 32 of 788 circuits in High Fire Risk Areas (HFRA) that are EPSS-enabled today. The remaining 756 circuits in HFRA will have devices postured in normal settings due to low FPI rating. Additionally, 2 EPSS Buffer-only circuits are enabled today.
