Red flag fire conditions are back in northern and central Arizona on Wednesday, with gusty winds and bone-dry air cranking up the risk of fast-moving wildfires. Arizona Public Service (APS) is warning that it may temporarily shut off power to specific neighborhoods around Flagstaff, while Valley residents can expect breezy, slightly cooler weather through midweek. Officials say the mix of strong gusts and very low humidity means even a tiny spark in rural or forested areas can turn into a real problem in a hurry.
Where The Red Flag Warning Hits
The National Weather Service office in Flagstaff has issued a Red Flag Warning for parts of northeastern Arizona, covering areas such as the Navajo Nation and the Little Colorado River Valley, from 11 a.m. to 9 p.m. MDT Wednesday. Forecasters are calling for southwest winds around 16 to 26 mph, with gusts that could reach about 44 mph, along with very low relative humidity in some zones. According to the National Weather Service, that setup is the kind that can take any new ignition and push it to grow quickly.
APS May Flip The Switch On Purpose
APS says it may activate a Public Safety Power Shutoff as early as 9 a.m. Wednesday, targeting roughly 5,800 customers in eastern Flagstaff and nearby communities including Doney Park, Timberline, Fernwood and Mormon Lake. The goal is to reduce the chance that electrical equipment becomes the source of a wildfire. The utility says crews will patrol power lines and work to restore service once conditions calm down enough to safely bring electricity back. Customers who rely on life-support or similar medical equipment are being urged to sign up for the company’s Medical Care program, according to APS.
Valley Forecast: Breezy Break From The Heat
Down in the Phoenix metro, the fire danger is lower but residents will still feel the effects of the system stirring things up to the north. Forecasters expect a modest cooldown by Wednesday, with highs sliding into the mid to upper 80s while afternoon breezes continue and humidity stays on the low side. Maricopa County’s outlook highlights a trend toward slightly cooler daytime highs and recurring afternoon breezes, and local station Arizona's Family has issued a First Alert Weather update echoing the same pattern for Valley neighborhoods.
How To Stay Ready When Conditions Turn Critical
Fire and weather officials are asking residents to treat this as a high-risk day, even if skies look clear. That means avoiding outdoor burning, tying down or securing loose yard debris and holding off on any projects that throw sparks, such as grinding or welding, while red flag conditions are in effect. If you see smoke or an active fire, call 911 right away.
Customers who live in the areas that could be affected by a Public Safety Power Shutoff are urged to make sure APS has up-to-date contact information and to keep an eye on the utility’s outage map. Anyone who depends on electricity for medical needs should register with APS, have backup plans in place and be ready to use them if the power goes out, according to APS and the National Weather Service.
