What

Flooding caused by excessive rainfall is 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

From late Saturday night through Sunday 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 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

  • Be aware of low-lying areas along your travel routes that are most likely to flood. 
  • Check your home’s emergency supplies, and make sure all members of the household know your emergency plan. 
  • Stay tuned for local weather updates on the situation as it develops.

If a Flood Warning is issued, it means that dangerous flooding is expected or already happening. 

  • Never walk, swim, or drive through flood waters or flooded roads.

If your home is likely to flood, or if authorities tell you to evacuate, do so immediately and move to higher ground.

Friday Flash Flood Potential

Created by the NWS Salt Lake City WFO

Tropical moisture will return to the area beginning Friday, bringing an increased risk of flash flooding, particularly to southwest Utah. Those with outdoor plans in the threat area Friday should consider alternate plans and have multiple ways to receive weather warnings.

An information graphic from the National Weather Service Salt Lake City, UT titled "Flash Flood Potential - Friday (10/30)".   Key Messages:Southwest Utah (including Zion National Park and St. George) is under a Slight Risk (Level 2 of 4) of flash flooding Friday (10/30).   Much of the rest of the southeastern half of Utah will be under a Marginal Risk (Level 1 of 4) of flash flooding during that time.   Main areas of concern include recent burn scars, normally dry washes, steep terrain, and slot canyons. Recent rain is resulting in higher than usual flows, enhancing the threat.   Preparedness:If you encounter flooded roadways, turn around, don’t drown!   Those with outdoor plans should monitor the weather and have multiple ways to receive warnings.
