Event narrative

A WYDOT official reported mud and debris were 3 feet deep in some locations just upstream along US Hwy 14. Many people were stranded in the area as local roads and the highway were impassable. A car was totaled when the driver attempted to drive through the flooded road. A private cabin was also damaged by the flooding. Hwy 14 was closed over the next 12 hours, opening back up the following morning.
