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.
IMPORTANT: This map does not reflect the most detailed and up to date information about announced Public Safety Power Shutoff events. For the latest information visit pge.com/pspsupdates.
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. 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. Extensive low clouds and fog exist across much of the territory this morning with a few high clouds streaming in from the North. Apart from some patchy morning drizzle along the coast, dry weather is expected through midday followed by a chance for widely scattered showers in the North and across the Bay Area this afternoon and evening as a cold, weather system drops into the territory. More widespread precipitation, in the form of showers and mountain snow, will spread north to south overnight through tomorrow morning and be primarily focused along the Sierra and across the central and southern territory with snow levels lowering to around 3500 – 5500’ by sunrise; however, the bulk of the snowfall will occur at higher elevations. Dry and cooler weather returns during the day tomorrow and will continue through Saturday with cool days and chilly nights. An extended stretch of wet and unsettled weather begins across the North late Saturday into early Sunday as a series of weather systems will move through the territory delivering periods of gusty winds, widespread rain, and mountain snow through at least the middle of next week and possibly longer. The return of precipitation will lead to improved dead fuel moisture values and some green-up in the grass crop, allowing for a continued reduction of fire potential across a vast majority of the territory. The 4 Month Seasonal Outlook issued December 1st from Northern Operations and Southern Operations Predictive Services calls for normal significant fire potential in all areas December through March.
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. It should not be used for any other purpose or by any other entity.
Not Planned – Conditions that generally warrant a PSPS event are not planned at this time.
Elevated – An upcoming event (a period of gusty winds, dry conditions, heightened risk) is being monitored for an increased potential of a PSPS event.
PSPS Watch – The company Emergency Operations Center (EOC) is activated for a reasonable chance of executing PSPS for public safety in a given county due to a combination of adverse weather and dry fuel conditions. A PSPS watch is typically only issued within 72 hours before the anticipated start of an event.
PSPS Warning – The company Emergency Operations Center (EOC) is activated and customers in areas being considered for PSPS have been or are being notified. This level indicates execution of PSPS is probable given the latest forecast of weather and fuels and/or observed conditions. PSPS is typically executed in smaller and more targeted areas than across an entire county. This level does not guarantee a PSPS execution as conditions and forecasts may change.
Although weather conditions help us determine when there's an increased risk for fire, we carefully review a combination of many criteria before shutting off power for safety.
NOTE: Although weather or other conditions where you live may not be at high risk for fire, your electricity could also be turned off due to the interconnectivity of the power grid.
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.
