| Brief Description: EVENT NARRATIVE: Bellemont Tornado #2 (5:54 - 6:50 AM): This tornado caused extensive forest damage (primarily south of Bellemont), along a discontinuous track which extended from 15 miles south of Bellemont, eventually crossing Hwy 180 northwest of Flagstaff. Very wide, severe forest damage (EF-2) occurred in the forest south of Bellemont. Tornado visually sighted by NWS staff at the Bellemont Weather Forecast Office. Tornado passed 1/3 mile west of the NWS Bellemont Weather Forecast office. Additional damage stats include: -28 rail cars derailed in Bellemont. -Semi trucks and trailers were overturned on I-40. -Power poles snapped on Camp Navajo. -Numerous forest roads blocked and campers were stranded by fallen trees. EPISODE NARRATIVE: 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 supper cell development. There were eight confirmed tornadoes on October 6, 2010 across northern Arizona. 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. | |||||||||||
