A Flash Flood Warning was issued for Morgan and Summit Counties, Utah, on July 22, 2026. Slow-moving thunderstorms producing heavy rainfall created the potential for dangerous flash flooding in the area.
Residents, travelers, and those participating in outdoor recreation were advised to remain alert because water levels can rise rapidly in canyons, low-lying roads, streams, and creeks.
Flash flooding can develop with little warning in Utah's mountainous terrain. Runoff from storms can quickly funnel into washes, rivers, and narrow canyons. Officials noted that even areas receiving minimal rain could face dangerous flooding if storms occur upstream.
Specific areas at risk include mountain canyons, small creeks and streams, low-water crossings, poor drainage areas, campgrounds, hiking trails, and roads prone to flooding. Motorists traveling on area highways were advised to prepare for possible temporary closures, standing water, and rapidly changing road conditions.
Safety recommendations for those in the warning area included moving to higher ground immediately if flooding begins and staying away from drainage channels and fast-moving streams.
Authorities advised against driving through flooded roadways, noting that even a small amount of moving water can sweep a vehicle away. Additionally, individuals were encouraged to delay camping, hiking, or other recreational activities in canyons until the threat passed.
The risk of flash flooding is increased during late July because it marks the height of Utah's monsoon season. During this time, moisture and daytime heating often produce intense evening and afternoon thunderstorms that generate heavy rainfall in short periods across central and northern Utah.
