Wider weather episode

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.
