When

Additional Details
- Widespread moderate to at times heavy precipitation is expected across much of southern, southeast and east central Utah beginning late Saturday night, and continuing throughout the day Sunday.
Moist antecedent conditions from recent heavy rains will result in efficient and excessive runoff, allowing all area washes, streams and rivers to run fast and high. Flood prone areas will likely become inundated at times, and backcountry roads will likely become impassable from this excessive runoff. - http://www.weather.gov/safety/flood
