Thunderstorm Wind in San Juan County, Utah

A severe thunderstorm forming on the nearby Abajo Mountains tracked over the city of Blanding in Southeast Utah, producing multiple severe weather hazards, including strong to severe winds. The peak recorded gust was 65 mph at KBDG AWOS at Blanding Municipal Airport, which occurred around 2 PM MDT. No reports of damage from wind were received.

Very deep tropical moisture associated with the remnants of Tropical Storm Alberto combined with monsoonal moisture was forced through eastern Utah and western Colorado due to a large high pressure ridge over the Central U.S. and a deep low pressure trough over the Great Basin. This deep moisture combined with strong instability and shear to produce widespread severe weather across eastern Utah and western Colorado with thunderstorms producing severe wind gusts, large hail and heavy rain which resulted in flash flooding and debris flows. One particular storm even produced a landspout tornado in southeast Utah. Frequent lightning also resulted in lightning damage in Montrose, Colorado.
