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.

 

Tuesday, January 14, 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.

The PG&E Emergency Operations Center remains activated for a targeted PSPS event in Kern County and the PSPS forecast continues to show warning status for Kern County through tomorrow as additional periods of dry and gusty winds are expected today and tomorrow. Winds diminished last night in southern Kern County, but another pulse of gusty east-southeasterly winds will develop this morning and continue into the early afternoon across the Tehachapis and I-5 corridor (Grapevine). These winds are associated with an ongoing moderate to strong Santa Ana wind event across Southern California and will continue at times through tomorrow afternoon with gusts in the 25-45 mph range. Offshore flow will likely continue across Southern California through Thursday; although, winds are expected to diminish in strength during this time. Relative humidity values will remain in the 20-40% range (or lower during the day) as offshore flow persists. Real-time and updated forecast data will be utilized to make the all-clear decision and initiate 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.
