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.

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).

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 low-pressure trough will remain positioned over the territory this week leading to cooler temperatures with a series of weather systems bringing a chance of precipitation to portions of the north and central territory through Wednesday. Apart from a chance for additional shower activity across the far North Thursday, dry and milder weather returns through the end of the week followed by a chance for additional precipitation across the north and central territory this weekend into early next week. Attached is the latest precipitation forecast through 5 am Friday from the new 2x2 km PG&E weather model (POMMS) as well as the latest European (ECMWF) and American (GFS) weather model 10-day precipitation forecast. Despite the expected precipitation over the period, rainfall totals for the season will remain below-normal across the territory; however, increases in fuel and soil moisture values will drive lower FPI values in the PG&E Fire Potential Index. 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.

Not Expected – Conditions that generally warrant a PSPS event are not expected 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 geographic zone 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 the PG&E Geographic Zones. This level does not guarantee a PSPS execution as conditions and forecasts may change.

The "7 Day Public Safety Power Shutoff Forecast map" (above) is displayed using nine PG&E Geographic Zones. Note that this map gives only a general idea of the area(s) that could be impacted by a potential PSPS. When an actual PSPS event is announced, detailed maps of the impacted areas will be available through our Public Safety Power Shutoff event information page.

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.

Low humidity levels, generally 20 percent and below.
Forecasted sustained winds generally above 25 mph and wind gusts in excess of approximately 45 mph, depending on location and site-specific conditions such as temperature, terrain, vegetation and local climate.
Moisture content: Condition of dry fuel on the ground and live vegetation (dead and live fuel moistures).
On-the-ground, real-time observations from PG&E's Wildfire Safety Operations Center and field crews.
A Red Flag Warning declared by the National Weather Service. IMPORTANT: A Red Flag Warning alone does not automatically trigger a Public Safety Power Shutoff.
Information from the National Interagency Fire Center (NIFC) and National Weather Service, including high risk days and locations considered “critical burn environments” in our service area. IMPORTANT: These indications alone do not automatically trigger a Public Safety Power Shutoff.

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.

SAFETY TIP: Help us reach you when it’s important. Make sure we have your correct email address and phone number so we can reach out to you in advance of a public safety power outage, when and where possible.
