Description:
ESFGJT
Anomalous moisture has become established across portions of
eastern Utah and western Colorado. Scattered thunderstorms capable
of producing heavy rain are expected this afternoon and early
evening. 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 steep terrain and recent burn scars.
Also, rain over the past several days has lead to saturated soils,
which increase the chances for excessive runoff.
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.
