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, May 27, 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.

No Public Safety Power Shutoff (PSPS) events are planned for the next week. Fair weather continues today with slightly warmer temperatures across the territory and morning low clouds near the coast. A weak weather system moving through the Pacific Northwest tomorrow and Thursday will bring increased onshore flow, more widespread coastal morning clouds and some cloud cover across the interior. A marked warmup is expected across the interior and inland portions of the Bay Area Friday and Saturday as high pressure builds over the region. Warmer than normal temperatures, along with breezy winds, low afternoon humidity and marginal overnight recovery might lead to elevated fire conditions across the interior Friday and Saturday. Cooler temperatures are anticipated late in the weekend into early next week as high pressure weakens. A few afternoon showers or thunderstorms may form over the higher southern Sierra today and tomorrow, better chances may develop later this weekend/early next week as a weather system moves into the region. Fuels: The annual grass crop has cured across the interior below 2500 feet but is still transitioning from live to dead in the Coastal Ranges. Live fuel moisture is on the decline across the lower elevations after reaching maximum annual values earlier this month. However, moisture content is beginning to increase in the higher elevations where the growing season is later. Dead fuel moisture values will fluctuate over the next week and are generally trending drier but are not near critical levels at this time. The latest 4 Month Seasonal Outlook from Northern Operations Predictive Services is forecasting normal fire activity across Northern California for May, and near to above-normal fire activity June through August for areas away from the coast. Southern Operations Predictive Services is forecasting near normal to slightly above normal fire activity for the South Coast area in June and in the interior locations during July and August. There are 538 of 788 circuits in High Fire Risk Areas (HFRA) that are EPSS-enabled today. The remaining 250 circuits in HFRA will have devices postured in normal settings due to low FPI ratings. Additionally, 2 EPSS Buffer-only circuits are enabled today.
