Event narrative

The intersection of State Road 4 and State Road 501 (West Jemez Rd.) was closed due to flash flooding.

Wider weather episode

An upper level high pressure system shifted westward centering over portions of Utah and western Colorado. With sufficient moisture as well as instability, storms initially developed over northern portions of the state during the afternoon hours. These storms increased in coverage into the early evening with general storm motions toward the west and southwest. The thunderstorms, though not severe, did produce significant amounts of rainfall in very short time durations. This led to flooding of the Las Conchas Fire burn scar as the storms moved from north to south covering the entire burn scar.
