scars.
* 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.
