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.

 

Thursday, January 16, 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.

Breezy southeast winds continue over the Grapevine/Tehachapis this morning with gusts in the 20-25 mph range. A Red Flag Warning also remains in effect over a small section of southern Kern County, just south of Lebec through 3 pm today. However, the offshore winds are expected to continue to calm down today with light winds likely by midday. While the wind will remain lighter overall tonight and over the next few days, a breezy northwest wind is expected to develop, starting tonight. This will lead to increased relative humidity values in the region, mainly on the windward side of the Tehachapis and into the south San Joaquin Valley. Elsewhere across the territory, fair and dry weather is expected to continue through the weekend with mild daytime temperatures, chilly overnight temperatures, and light onshore winds. PG&E Meteorology is monitoring another potential offshore wind event early next week. However, details related to the timing and strength of the winds remain unclear. 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 28 of 788 circuits in High Fire Risk Areas (HFRA) that are EPSS-enabled today. The remaining 760 circuits in HFRA will have devices postured in normal settings due to low FPI rating. Additionally, 2 EPSS Buffer-only circuits are enabled today.
