Learn the role weather plays in a power shutoff


If weather forecasts indicate gusty winds and dry conditions, combined with a heightened fire risk, it may be necessary for us to turn off the electricity serving that area. This is called a Public Safety Power Shutoff (PSPS). Learn more about a PSPS.

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.

NOTE: This forecast is based on weather conditions and fuel moisture content only and does not include other criteria used to determine whether a PSPS may be necessary.

No Public Safety Power Shutoff (PSPS) events are planned for the next week. A weather system will push into the Pacific Northwest today, slide south, and linger over Baja California and the Desert Southwest through the weekend. This will bring cooler temperatures today, followed by a brief period of north to northeast winds tomorrow morning through Friday morning, with maximum wind gusts currently projected to be remain below 30 MPH. Temperatures will warm tomorrow and Friday as a ridge builds into the region. High pressure will weaken over the weekend, increasing onshore flow and cooling temperatures to near normal. To start next week, a new weather system is favored to push into the Pacific Northwest, resulting in cooler temperatures, breezy conditions, and chances for showers in the far North. Drier and warmer weather is favored to return for the middle of next week. Dead fuel moisture values away from the coast continue to track near historical lows for this time of year and live fuel moisture content is near critical levels in many areas. The 4 Month Seasonal Outlook issued August 26th from Northern Operations and Southern Operations Predictive Services calls for normal to above normal significant fire potential through November with near normal returning to all areas in December.

Please note: This forecast is published daily by an operational meteorologist from PG&E’s Meteorology and Analytics team. This forecast has been customized for PG&E utility operations and should not be used for any other purpose or by any other entity. This forecast only provides a broad overview for a potential Public Safety Power Shutoff (PSPS) event in the next 7 days as determined from an analysis of forecasted 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; however, PSPS decisions are made at more granular levels; thus, 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.
