NWS confirms third tornado struck northern Arizona last week

The National Weather Service confirmed on Wednesday that a third tornado touched down in northern Arizona during a severe weather event last week. This latest verification adds to the two other twisters that were officially confirmed in the days preceding this announcement. The newly identified storm is now designated as the Wing Mountain tornado.

This specific tornado was the first of the three to make contact with the ground on October 21. However, it was the final one to be officially verified by meteorological officials. The timing of its occurrence marks it as the earliest event in a series of destructive storms that swept through the region on that date.

According to data from the NWS Flagstaff office, the tornado emerged approximately 3.5 miles north of Bellemont at 5:41 a.m. The system moved in a northeastward direction through the local forested terrain. It eventually dissipated just west of Highway 180. Bellemont is a community located immediately to the west of the city of Flagstaff.

The path of the Wing Mountain tornado extended for 2.3 miles. As it traversed the landscape, it caused significant damage to the vegetation. Large ponderosa pines were uprooted and snapped along the track of the storm. Meteorologists estimate that the peak wind speeds reached 110 miles per hour during the event.

The confirmation of this third tornado follows the verification of two other distinct events that occurred on the same day. One was located near Prescott, while the other struck the area of Heber-Overgaard. Multiple tornado warnings had been issued by authorities on October 21 to alert residents to the potential threat.

The first of the other two confirmed storms is known as the Spruce Mountain tornado. It touched down near Prescott at 7:32 a.m. This event was rated as an EF1 on the Enhanced Fujita scale. Maximum wind speeds for this twister were estimated at 105 miles per hour.

The Spruce Mountain tornado remained on the ground for a duration of 14 minutes. During that time, it traveled a distance of 8 miles. The width of its path was measured at approximately 300 yards. No injuries were reported in connection with this specific storm.

The second other confirmed tornado struck Heber-Overgaard later in the day at 6:59 p.m. This event was also rated as an EF1 with peak winds estimated at 110 miles per hour. The storm stayed on the ground for 11 minutes and covered a distance of 9.25 miles. The path width for this tornado was about 350 yards.

One individual was injured during the Heber-Overgaard tornado. This was the only injury reported among the three confirmed events. No injuries were associated with the Wing Mountain tornado near Flagstaff or the Spruce Mountain tornado near Prescott.

The weather service's detailed analysis provides a clearer picture of the day's severe weather activity. The confirmation process involves examining damage patterns and atmospheric data to verify the nature of the storms. These findings help in understanding the scale and impact of the weather events that affected northern Arizona last week.
