GRAND JUNCTION, Colo. – Torrential rainfall over the weekend shattered October precipitation records across western Colorado, triggering flash flooding, mudslides, and washed-out roads from Mesa County to the San Juan Mountains. Grand Junction recorded one of its wettest periods on record, with over 2 inches falling between Friday and Sunday.
According to the National Weather Service in Grand Junction, tropical moisture funneled north from the Pacific produced widespread heavy rain, ranking October 10–11, 2025, as the fifth-wettest two-day stretch in the city’s history. A daily total of 1.35 inches on Friday placed seventh all-time. Several nearby gauges in the San Juan Mountains topped 5 inches, including 6.3 inches at Wolf Creek Pass and 5.6 inches near the Weminuche Wilderness.
Officials reported flooding along small rivers and creeks, with localized slides near U.S. 160 and State Highway 145. In Archuleta and La Plata Counties, heavy runoff led to temporary road closures and debris flows near Durango and Pagosa Springs. Emergency managers urged drivers to avoid crossing flooded roadways and to report washouts to local authorities.
The Colorado Department of Transportation said cleanup and drainage work will continue into early week as drier air returns. Residents are advised to stay alert for unstable slopes and lingering mud on backcountry roads as the saturated ground slowly dries.
