NWS Confirms Third EF1 Tornado Near Flagstaff From Oct. 21 Outbreak

Confirmation of the Wing Mountain twister completes the NWS survey and could prompt requests for state or federal aid.

Overview

  • The National Weather Service has confirmed a third EF1 tornado from the Oct. 21 storm, identifying the Wing Mountain touchdown about 3.5 miles north of Bellemont that carved a roughly 2.3-mile damage path.
  • NWS and mapped radar data estimate peak winds near 110 mph for Wing Mountain and report large ponderosa pines uprooted or snapped along the path.
  • The outbreak also produced EF1 tornadoes near Prescott (Spruce Mountain) and Heber-Overgaard with peak winds of about 105–110 mph and one reported non-life-threatening injury in Heber-Overgaard.
  • Local officials have launched damage surveys and cleanup operations and Navajo County has declared an emergency while assessments continue to determine recovery needs and possible aid.
  • NWS ratings come from ground surveys and partner radar products like the Iowa Environmental Mesonet, which can show different path lengths or widths and may refine assessments as more field data arrive.
