...RISK OF FLASH FLOODING AND DEBRIS FLOWS INCLUDING RECENT BURN
SCARS...

Anomalous moisture has become established across portions of
eastern Utah and western Colorado. Rainfall rates of 1-2 inches
per hour will be possible with the stronger storms. These rates
could lead to flash flooding and debris flows especially over
recent burn scars.

Storms over the last few days have helped prime lower levels of
the atmosphere and saturate the ground where rain was observed.
Several locations across southwest Colorado reported over 0.5
inches of rain within 30 minutes; which is more than sufficient
to create issues in our steep, rocky terrain that is already
susceptible to flash flooding. This environment also triggers
heightened awareness over recent (or actively burning) fires,
due to the burnt ground`s inability of absorbing moisture under
heavy rainfall. As such, we continue to emphasize the potential
for flash flooding and debris flows in this regime.

As a reminder: Keep an eye on our forecasts through the end of
the week and stay tuned for updated hydrology alerts if
visiting or if you reside below vulnerable terrain to flash
flooding and/or debris flows. Storms across the west develop
quickly, leaving little room for lead time in flashy terrain.
