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.
Sunday, May 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.
No Public Safety Power Shutoff (PSPS) events are planned for the next week. Breezy to gusty northerly winds are expected to pick up again this afternoon with gusts up to 35-45 mph in the Sacramento Valley and Coast Ranges. Relative humidity values will likely fall into the teens in parts of the Sacramento Valley this afternoon and tomorrow afternoon, leading to a slight increase in fire potential. As a result, a Red Flag Warning has been issued in the Sacramento Valley from 0800 today through 2000 tomorrow evening. Breezy northerly winds continue tomorrow with gusts up to 35 mph in parts of northern San Joaquin Valley, southern Sacramento Valley/Delta, and on elevated coast terrain. Lighter winds are favored Tuesday through the rest of the week. It will be dry today and a few degrees warmer. The warming trend continues tomorrow and through Wednesday this week with high temperatures getting into the mid-90s in the Central Valley on Wednesday. While temperatures are likely to remain above normal late this weekend into next weekend, gradual cooling is likely during that period.
Fuels: The annual grass crop is transitioning from live to dead across the territory, with more advanced curing farther south. Meanwhile, live fuel moisture values are near peak annual moisture content across lower elevations and beginning to increase in higher elevations. Dead fuel moisture values will increase slightly over the next couple days as cooler weather develops and are generally trending close to normal for this time of year. 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 667 of 788 circuits in High Fire Risk Areas (HFRA) that are EPSS-enabled today. The remaining 121 circuits in HFRA will have devices postured in normal settings due to low FPI ratings. Additionally, 59 EPSS Buffer-only circuits are enabled today.
