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 21, 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.

Afternoon Update: Winds have relaxed in the Tehachapi mountains and the Weather All-Clear has been issued for the most recent PSPS event and crews are currently in the process of patrolling and restoring power. Morning Discussion: Santa Ana winds are expected to quickly dissipate across Kern County this morning, however breezy winds and low relative humidity continue for the time being. As a result a PSPS continues for a small population of customers in the Tehachapi mountains and Kern County remains on Warning status. Fair and dry weather is expected to follow this afternoon into most of tomorrow. The latest modeling continues to indicate that breezy to locally gusty Santa Ana winds may return on Wednesday night and linger into either Thursday evening or Friday morning. PG&E Meteorology is closely monitoring this next period of wind for fire danger concerns. This coming weekend, a new low pressure system is expected to track more directly over the state, bringing breezy to gusty winds across Northern California and a slight chance for precipitation in the far southern portion of the state, although the weather models remain highly uncertain on the chance for measurable precipitation. 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 36 of 788 circuits in High Fire Risk Areas (HFRA) that are EPSS-enabled today. The remaining 752 circuits in HFRA will have devices postured in normal settings due to low FPI rating. Additionally, 2 EPSS Buffer-only circuits are enabled today.
