A severe flood watch has been issued for a large portion of Utah through midnight, as the National Weather Service warns that excessive rainfall could trigger flash flooding across the state. The watch, effective through 11:00 p.m. on Sept. 6, 2026, follows a period of dangerous flooding in July that claimed the lives of a Provo Fire Captain and his family.
Widespread Rainfall and Flooding Risks
The National Weather Service Salt Lake City issued the flood watch on Sept. 6, noting that flash flooding remains possible due to excessive rainfall. The watch covers several regions, including the Central Mountains, Sanpete Valley, Sevier Valley, Wasatch Plateau/Book Cliffs, Western Uinta Basin, Bryce Canyon Country, South Central Utah, Southern Mountains, Upper Sevier River Valleys, Southwest Utah, and Zion National Park. It also encompasses Eastern Juab and Millard Counties.
Meteorologists expect excessive rainfall to arrive Sunday afternoon, driven by the arrival of deep tropical moisture across much of central and southern Utah. Rainfall rates are expected to reach between 0.1 and 0.3 inches per hour, with isolated higher rates possible.
Burn Scars Increase Flood Danger
The threat of flooding is heightened in areas containing recent burn scars, such as Cottonwood, Widemouth 2, Forsyth, France Canyon, Monroe Canyon, and Black Canyon. According to the National Weather Service, excessive runoff from these areas may result in flooding of rivers, creeks, streams, dry washes, and slot canyons, as well as low-lying locations like slickrock areas.
State Forester Jamie Barnes noted that burn scars can remain highly unstable for years, creating dangerous flooding and debris flows even with relatively small storms. The threat remains elevated throughout the remainder of the monsoon season, particularly in areas affected by recent wildfires.
Impact of Historic Wildfire Season
The current weather emergency follows a period of extreme environmental stress in Utah. On July 22, 2026, Governor Spencer J. Cox declared a state of emergency for Beaver, Piute, and Sevier counties due to the combined impacts of a historic wildfire season and catastrophic flooding.
During that period, Utah experienced one of its most destructive fire seasons in recent history, with more than 590 wildfires burning nearly 380,000 acres statewide. The Cottonwood Fire alone accounted for more than 97,000 acres burned in Beaver and Piute counties.
Previous Flooding and Infrastructure Damage
The flooding in July caused significant damage to infrastructure and loss of life. Governor Cox acknowledged the deaths of Provo Fire Captain Spencer Long, his wife Katrina, and three of their children, who were swept away by flash flooding in Wayne County.
The flooding previously destroyed portions of State Route 153 in Beaver Canyon and disrupted water systems serving Beaver City, Marysvale, Junction, and Circleville. Damage was also reported to homes and water infrastructure in Sevier County, including the town of Koosharem.
Safety and Emergency Response
Local officials are urging residents to monitor forecasts and prepare to take action if flash flood warnings are issued. The National Weather Service advises the public to avoid flooded roadways or drainages and to heed all evacuation orders.
The state's emergency declaration, signed by Governor Cox on July 22, remains in effect for 30 days unless extended by the Legislature, allowing for the deployment of resources to support local response and recovery efforts.
Forecast Outlook
The current flood watch is scheduled to expire at midnight MDT tonight. Residents in flood-prone areas are encouraged to stay informed as monsoon moisture continues to impact the region.
