The National Weather Service (NWS) office in Flagstaff, Arizona, issued a tornado warning for a portion of Coconino County early Wednesday morning, October 21, 2026 [1]. The warning was issued at 5:42 AM MST and expired three minutes later at 5:45 AM MST [1]. The NWS stated that the storm which prompted the warning had weakened below severe limits and no longer appeared capable of producing a tornado, leading to the warning's expiration [1].

This brief warning occurred as a Pacific weather system approached Arizona, bringing a deep surge of moisture [3][4]. Severe thunderstorms were possible across the state, with isolated threats of wind gusts over 60 mph and hail over 1 inch in diameter [3]. There was also a chance for a few tornadoes, with the severe threat expected to peak on Wednesday afternoon and evening [3]. The Storm Prediction Center (SPC) placed portions of the area in a Slight to Enhanced risk for severe weather on Wednesday, noting that an isolated tornado or two could not be ruled out [6]. The NWS also forecasted a very slight chance of an isolated tornado in the eastern half of the state [4].

Widespread showers and thunderstorms were expected throughout Wednesday and Thursday [4]. Eastern Arizona could see 1-3 inches of rainfall [4]. Flood Watches were also in effect for various areas, including the Little Colorado River Valley in Coconino County, issued on October 20 and expiring on October 22 [2]. The NWS Flagstaff also issued alerts for Gila County on October 21 regarding a significant threat to property or life [2]. General threats of flooding and flash flooding were anticipated across the region [4].

Despite the official NWS Flagstaff tornado warning, a weather tracking website, tornadopath.com, reported that the National Weather Service had issued no tornado warnings for Arizona on Wednesday, October 21, 2026 [5]. This report was last updated at 8:04 AM on the same day [5].
