The National Weather Service has issued a flood watch for parts of eastern Utah.
Forecasters say the weekend's warm temperatures have caused rapid snowmelt on mountains in western Colorado and eastern Utah, leading to steady rising river levels.
Flooding could occur along Utah's Green River near Jensen, east of Vernal, and along smaller creeks and streams that flow into the Green.
On Sunday morning, the weather service said the Green River was at 6.3 feet. Flood stage is reached at 10.8 feet. Forecasters predict the river could reach flood stage by Friday.
