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 18, 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.
Areas of fog and low clouds can been seen across a good portion of the territory this morning. Otherwise fair and dry weather is expected today. Breezy offshore winds will begin to develop tomorrow across portions of the Sierra as a trough of low pressure pushes through the Great Basin region, allowing for offshore flow to develop across much of the state. On Monday as this trough of low pressure continues to dig southward, breezy to gusty winds will develop in the Tehachapi mountains south and east of Bakersfield, a portion of the territory where winter precipitation is running significantly below normal and green up has yet to occur. These dry winds will lead to a period of elevated fire weather Monday into Tuesday before high pressure returns Tuesday leading to calmer conditions. Kern county has been upgraded to Watch status as weather models continue to be consistent in the evolution of these dry gusty winds in the Tehachapi mountains. After Tuesday, fair and dry weather is expected through at least of the end 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 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.
