Debris Flow in Ouray County, Colorado
Debris Flow August 26, 2023 · Ouray County, Colorado
Where the report was made, with tornadoes recorded within 15 miles over the years.
What the National Weather Service wrote
Mud and debris flowed across County Road 17 at Corbett Creek near the Dallas Trailhead as a result of heavy rain from thunderstorms. The road remained closed through the end of the month.
The wider storm
Even as high pressure began to build into the region, plenty of deep moisture remained entrenched across western Colorado. This led to another round of scattered showers and thunderstorms. Daytime heating and marginal instability fueled some stronger storms, particularly over the higher terrain. One such storm was nearly stationary over the east side of the Grizzly Creek Fire burn scar for an extended period of time, which resulted in some debris flows over I-70. Additionally, heavy rain from storms resulted in debris flows in portions of Ouray County.
Began near Portland (38.0548, -107.6918).
