Key Points
- Storms far away can flood a dry canyon
- Check the forecast and flood rating before you go
- Skip slot canyons if rain is possible
- Move to high ground at the first sign of rising water
Flash floods are one of the biggest dangers in Southern Utah canyons. A storm many miles away can send a wall of water through a dry canyon with no warning.
Check The Forecast First
Look at the National Weather Service forecast and the flash flood potential rating before entering any slot canyon or narrow wash. If rain is likely anywhere upstream, choose another hike.
Know Your Escape Routes
In a narrow canyon there may be nowhere to climb. Notice high ground as you walk.
If Water Rises Or Turns Muddy
Move to higher ground right away. Do not wait to see how bad it gets, and never try to cross moving water.
After The Storm
Washes can stay dangerous for hours. Wait for the water to drop and check conditions before you continue.
Do
- Check the National Weather Service forecast
- Look for high ground as you hike
- Turn around if skies darken upstream
Don’t
