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).

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 expected for the next week or longer. A strong ridge of high pressure will continue to produce hot weather across interior locations today while areas closer to the coast will see cooler weather today under a stronger marine influence. The cooler weather will extend inland tomorrow into the rest of the interior as the high pressure ridge moves eastward and out of the territory.  Temperatures will cool back to near-normal or below average on Saturday as a low pressure system moves into the central and northern part of territory with showers and scattered thunderstorms from about Big Sur northward along the coast and Sacramento across the interior.  Another weak weather system may move into the territory early next week with precipitation possible across elevated terrain and Sierra and a slight chance in the low-elevation areas into mid-week. Although the seasonal green-up continues across mid-elevations, the current period of hot and dry weather has accelerated the curing of finer, flashier fuels at lower elevations leading to higher FPI ratings in the PG&E Fire Potential Index into R4 across parts of the interior. The latest forecast by the National Interagency Fire Center Predictive Services is little changed from the previous month and is favoring normal significant large wildfire potential across most the territory this month. Above normal significant large wildfire potential is then expected across the majority of the northern half of the territory in June with average or below normal significant wildfire potential across the southern half of the state. PG&E meteorology will continue to monitor weather, fuels and long-range forecasts/outlooks closely.

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 broad PG&E Geographic Zones numbered 1 - 9; however, PSPS decisions are made at more granular levels; thus, only a portion of a zone 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.

Whether it's a big winter storm on the horizon or an extended spell of hot and dry weather, PG&E continuously monitors the weather to make sure we're ready to respond to whatever hits our service area. A team of meteorologists analyzes information around the clock to make sure we have the right data to plan ahead and help our customers prepare.


This interactive weather map was created by collecting information from weather stations or cameras throughout PG&E's service territory. The weather stations can vary in the type of information collected (for example, one may report wind only, while another may report humidity, temperature, wind speed and more). Also, each weather station includes its own information timestamp.


We've made this map available to our customers so that you can have the latest information that may affect your plans to help you prepare. Learn how to use the interactive features to display the data you want to see by clicking on the information bar below the map.
