A widespread flood watch for portions of southern and eastern Utah was cancelled by the National Weather Service on Sunday, September 6, 2026, as the threat of flash flooding diminished. While the immediate threat of widespread flooding has passed, meteorologists noted that light to moderate rain may continue through the overnight hours, potentially causing minor flows in some streams and washes.
Flood Watch Cancellation Details
The National Weather Service in Salt Lake City issued the cancellation at 7:06 PM MDT on Sunday, September 6, 2026. The decision to end the watch applies to a vast portion of the state, covering several counties and major natural landmarks.
According to the National Weather Service, flash flooding is no longer expected to pose a widespread threat across the affected regions. However, the agency cautioned that residual precipitation could still lead to minor water increases in various drainage areas. This transition follows a period where several areas were under heightened alert for sudden, heavy rainfall events.
Affected Regions and Communities
The areas previously under the flood watch included several prominent regions and communities across Utah. The cancellation covers the Wasatch Plateau, the Book Cliffs, and the Western Uinta Basin. It also encompasses the Central Mountains, the Sanpete Valley, and the Sevier Valley.
Specifically, the National Weather Service identified several communities and landmarks within the watch zone, including Castle Dale, Scipio, Bryce Canyon City, Mt Pleasant, Cedar City, Fish Lake, Salina, Kanab, Fillmore, Scofield, Nephi, Cove Fort, Milford, Brian Head, Indian Canyon, Ephraim, Joes Valley, Price, Beaver, Panguitch, Richfield, Circleville, Duchesne, Roosevelt, Koosharem, Springdale, Escalante, Alton, and Manti. The watch also extended to the Southern Mountains, Upper Sevier River Valleys, Bryce Canyon Country, South Central Utah, Southwest Utah, and Zion National Park.
Monday Forecast for Southern Utah
As of 10:29 AM MDT on Monday, September 7, 2026, the National Weather Service's flash flood potential rating for southern Utah indicates that flash flooding is not expected in several major recreational and protected areas.
For the remainder of Monday, flash flooding is not expected in the following locations: Arches National Park, Bryce Canyon National Park, Canyonlands National Park, Capitol Reef National Park, Glen Canyon National Recreation Area, Grand Staircase-Escalante East, Grand Staircase-Escalante West, Natural Bridges National Monument, Grand Gulch, San Rafael Swell, Snow Canyon / Red Cliffs, and Zion National Park.
Extended Weather Outlook
The National Weather Service's automated hydrologic observations and flash flood potential ratings suggest that the risk remains low for the immediate future. For the remainder of Monday and through Tuesday, the forecast for these southern Utah locations remains at a level where flash flooding is not expected.
Looking further ahead, the National Weather Service indicates that flash flooding is also not expected in these same southern Utah areas for Wednesday. This suggests a stabilization of weather patterns in the region following the recent period of elevated flood risk.
Weather Monitoring Services
The National Weather Service Salt Lake City provides continuous monitoring of weather hazards including flash floods, severe weather, and heavy rain. The agency maintains detailed information on local hazards, including graphical hazardous weather outlooks and current conditions.
In addition to flood monitoring, the agency provides data on snow and precipitation, fire weather observations, and radar for the Salt Lake City and Cedar City areas. This data is critical for managing risks in high-traffic areas such as the various national parks and monuments located throughout the southern and eastern portions of the state.
Safety Information
Residents and visitors in the affected areas should continue to monitor local weather updates, particularly if light to moderate rain persists. While the widespread threat has been removed, the potential for minor stream flows remains a factor for those near washes or small streams during overnight precipitation.
