Short path of significant tornado damage between two other tracks near the Mogollon Rim. Aerial imagery was also used in the analysis. Start and end times estimated from radar data.
The wider storm
A strong low pressure center over California pushed abundant moisture over Arizona producing widespread thunderstorms with numerous severe storms. Strong vertical wind shear...with helicity in the 400-450 range...also provided an environment for supercell development. There were eleven confirmed tornadoes on October 6, 2010 across northern Arizona (three of the tornadoes were within 2 miles of the NWS Forecast office). This breaks the old record for the most tornadoes in Arizona for one day. The Arizona Governor signed a declaration of emergency for Coconino Country for $200,000 to be used for emergency response and public infrastructure repair.
Began near Sedona Arpt (34.9810, -111.8760).
