Wheather Alert Summary: 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.
