FLAGSTAFF — APS is warning customers in high fire-risk areas of east Flagstaff and the Grand Canyon that they may face temporary power shutoffs starting as early as 9 a.m. on Saturday, June 27. The power outages may last from 12 to 24 hours.
APS says the potential outages are a proactive measure due to severe fire weather conditions.
APS meteorologists and fire mitigation specialists are closely tracking the situation, which is expected to worsen by the weekend because of dry terrain, low humidity, and high winds.
Impacted customers have already been notified by APS.
Ten thousand customers may be impacted in the following areas:
- Doney Park
- Timberline
- Fernwood
- Mormon Lake
- Cosnino
- Sunset Crater
- Walnut Canyon
- Valle
- Some east Flagstaff neighborhoods
- Tusayan
- Grand Canyon National Park – south and east rims
Preparations for a power outage
- If you rely on life-sustaining medical equipment requiring electricity, register for the APS Medical Care program at 602-371-7171 or 800-253-9405. This notifies APS of your needs in the event of an outage.
- Build your emergency kit containing flashlights, batteries, non-perishable food, and bottles of water.
- Check your smoke detectors’ batteries and ensure they will function without power.
- Learn how to manually open your electric garage door or security gates.
- Check on your neighbors to see if they need help preparing.
During the power outage, residents should:
- Use generators safely (outside and away from windows).
- Disconnect appliances and electronics to avoid damage from electrical surges.
- Keep refrigerators and freezers closed to retain temperatures.
- Visit the Murdoch Center (203 E Brannen Ave) during the outage to get information, charge medical devices, phones or small electronics, refrigerate medicine, or grab a bottle of water.
- Monitor the APS Outage Map for outage times.
The City of Flagstaff prepares annually for the possibility of these types of power outages.
Potable water will continue to flow to City residents as normal, and there will be no impact on the Fire Department’s ability to respond to and fight fires.
Residents may notice temporary impacts to some streetlights or recreation facilities and services. More information on these temporary impacts will be shared at Flagstaff.az.gov/PSPS as it becomes available.
