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, December 28, 2024
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.
No Public Safety Power Shutoff (PSPS) events are planned for the next week. A band of moisture will continue to spread light rain and higher elevation mountain snow across the North today while the central and southern portions of the territory remain dry. The last in a series of weather systems will move into the North Coast tonight and push across the northern half of the territory tomorrow bringing moderate to locally heavy rain, higher mountain snow along with a slight chance of thunderstorms. Gusty southerly winds locally reaching speeds 45-55 mph over higher terrain will accompany this weather system along the North Coast tonight and spread across the northern interior overnight/tomorrow morning. Due to the warm nature of this weather system, snow levels will generally stay above 7000-8000 feet today, falling to around 5000 feet tomorrow. Precipitation may reach south to a Big Sur to Yosemite line tomorrow, however the southern interior will likely stay dry. Generally fair and dry weather will prevail next week/into next weekend and fog/low clouds may form and become persistent in the Central Valley. A weather system passing to the north may bring some light precipitation to the far North mid-week and again next weekend.
Fuels: Dead fuel moisture values will continue to increase as winter precipitation is expected across most of the territory. However, live fuel moisture values remain near seasonal minimums and are entering winter dormancy. Lastly, new growth of the annual grass crop is occurring for many areas in the central and northern part of the territory. The latest 4 Month Seasonal Outlook from Northern Operations Predictive Services is forecasting normal fire activity across the entire territory December through March while Southern Operations Predictive Services is forecasting normal to above normal fire activity in December followed by normal fire activity January through March.
There are 0 of 788 circuits in High Fire Risk Areas (HFRA) that are EPSS-enabled today. The remaining 788 circuits in HFRA will have devices postured in normal settings due to low FPI ratings. Additionally, 0 EPSS Buffer-only circuits are enabled today.
