The National Weather Service (NWS) Flagstaff office issued a Tornado Warning for parts of Coconino County, Arizona, on October 21 [1]. This urgent alert was put into effect at 5:28 AM MST and was scheduled to expire a short time later, at 5:45 AM MST on the same day [1]. At the time the warning was issued, NWS Flagstaff reported that a severe thunderstorm, showing radar-indicated rotation and capable of producing a tornado, was detected near Maine [1]. This location is approximately 14 miles west of Flagstaff, and the storm was moving northeast at a speed of 40 mph [1].

The primary hazards specified in the NWS warning included a confirmed tornado threat and the potential for quarter-sized hail [1]. The basis for this critical warning was radar-indicated rotation within the thunderstorm, suggesting the conditions for tornado formation were present [1]. The NWS detailed several potential impacts, such as flying debris, which poses a significant danger to individuals without adequate shelter [1]. The warning also anticipated that mobile homes would likely suffer damage or be destroyed, and there was a high probability of damage to roofs, windows, and vehicles [1]. Extensive tree damage was also listed among the likely consequences [1].

The geographic scope of the warning encompassed several specific locations. These included Fort Valley, Parks, Bellemont, Garland Prairie, Government Prairie, Maine, Camp Navajo, Wing Mountain, and Lava River Cave [1]. Crucially for travelers, the warning also covered sections of major transportation arteries: Interstate 40, specifically between mile markers 176 and 187, and Highway 180, between mile markers 223 and 227 [1].

Despite this official alert from the NWS, conflicting reports emerged from other weather monitoring platforms during the same period. A summary of tornado warning activity for Arizona published on tornadopath.com, updated at 8:04 AM on October 21, indicated that the National Weather Service had issued no tornado warnings for the state on that particular day [2]. This presented a direct contradiction to the active warning from NWS Flagstaff [1][2].

Further adding to the potential for confusion, AccuWeather's reports as of 3:21 PM on October 21 showed no active warnings or advisories specifically for Coconino County [3]. The discrepancy between the official NWS warning, which signals an immediate threat to life and property, and the lack of such warnings on other prominent weather tracking services, highlights a potential information gap that could affect public safety responses during severe weather events [1][2][3].
