Hydrologic Outlook issued July 20 at 10:32AM MDT by NWS Grand Junction CO

10:32 AM — July 21st, 12:00 AM

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.

Overview

Manti-La Sal National Forest is a 1,413,111-acre forest stretching from central Utah to southeastern Utah and into Colorado, divided into three primary land areas: the Manti Division, the La Sal Division at Moab, and the La Sal Division at Monticello. The forest is currently OPEN with no fire restrictions as of September 13, 2025 (Stage One restrictions were lifted due to favorable conditions). Recent significant activity includes the Deer Creek Fire closure on the Moab Ranger District, which was rescinded on August 22, 2025, and that area is now reopened. Current notices include La Sal Mountain Loop Road construction work ongoing, and Lake Fork Canyon has had road work and flooding concerns requiring users to report any damage. Fire danger is currently LOW across all ranger districts (Sanpete, Ferron/Price, Moab, and Monticello). Standard 14-day limit applies to both developed and undeveloped campsites. Road and trail accessibility varies by elevation and weather, so checking conditions with ranger district offices before visiting is advised, especially during seasonal transitions. Recent press releases indicate Christmas tree and firewood permits are available online through Recreation.gov.
