A large severe thunderstorm complex formed over east-central Utah during the morning hours of the 31st and developed a remarkable bow echo as it moved across central and northern Utah. This same system held together as it entered southwest Wyoming and produced wind gusts in excess of 60 mph downing a large tree in Evanston.

The same storm which downed a tree at Evanston (see above) produced remarkable winds and abundant damage in Sweetwater County as it moved through. Winds at Flaming Gorge Reservoir went from calm to gusting over 70 mph within seconds. Very heavy rain and wind driven pea-sized hail were also reported. These hurricane force winds lasted from 45 minutes to an hour driving a few docks over five feet onto the shore. These winds also produced damage in the cities of Green River and Rock Springs. Numerous tree limbs up to four inches in diameter were snapped off in Green River and Rock Springs. Also, the winds blew out the windows of 11 automobiles and took the roofing off several homes under construction in Rock Springs.
