APS to Activate Public Safety Power Shutoff in Flagstaff/Grand Canyon Area to Help Prevent Wildfires
Wildfire risk is expected to reach critical levels this weekend in states across the western U.S., causing the National Weather Service to issue Fire Weather Watches and Red Flag Warnings across the region. Electricity providers in multiple states are actively evaluating or issuing Public Safety Power Shutoff warnings.
In Arizona, the extreme risk is prompting APS to temporarily shut off power as early as 10 a.m. Saturday, June 27, 2026, unless forecasted weather conditions significantly improve. At this time, this planned safety shutoff is limited to approximately 8,000 customers in high fire-risk areas in and around Flagstaff and the Grand Canyon. This action helps prevent electrical equipment from starting or contributing to a wildfire. APS meteorologists are tracking extreme fire weather, forecasting an approaching weather system with the potential for strong wind gusts, low humidity and high temperatures. Dry vegetation further increases the threat.
Who will be impacted and how long is power expected to be out?
While weather patterns may change, forecasted conditions are worsening and APS is currently projecting a limited and targeted group of approximately 8,000 customers who will experience a temporary, planned safety outage. Impacted customers are in the following areas:
- Doney Park
- Timberline
- Fernwood
- Mormon Lake
- Cosnino
- Sunset Crater
- Fort Valley/Baderville
- Walnut Canyon
- Valle
- Some east Flagstaff neighborhoods
- Tusayan
- Grand Canyon National Park – south and east rims
APS began providing advanced notifications to customers on Tuesday, June 23, 2026, through their preferred method of contact selected on their account. Updated notifications continued throughout the week, encouraging customers to prepare.
Given the forecasted duration of the extreme fire conditions, restoration is expected Sunday afternoon, but timing depends on weather conditions, required inspections and any needed repairs. APS will communicate updates directly to impacted customers and through the APS outage map as information becomes available.
