Flood Watch

Flood Watch issued November 1 at 12:36PM MST until November 1 at 11:00PM MST by NWS Salt Lake City UT
Nov 1, 12:36 PM → Nov 1, 11:00 PM
WHAT: Flooding caused by excessive rainfall continues to be
possible.

WHERE: A portion of Utah, including the following areas, Castle
Country, San Rafael Swell, Bryce Canyon Country, Capitol Reef
National Park and Vicinity, Glen Canyon Recreation Area/Lake
Powell, South Central Utah, Southern Mountains, Western
Canyonlands, Lower Washington County and Zion National Park.

WHEN: Until 11 PM MST this evening.

IMPACTS: Excessive runoff may result in flooding of rivers,
creeks, streams, dry washes, slot canyons, and other low-lying and
flood-prone locations such as slickrock areas and recent burn
scars.

ADDITIONAL DETAILS:
- Widespread moderate to at times heavy precipitation is expected
across much of southern, southeast and east central Utah tonight
through this evening.

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.
