PRECAUTIONARY/PREPAREDNESS ACTIONS...

Have a way to receive Flash Flood Warnings and be prepared to take

Consider changing your plans if you were going to hike, boat, or
paddleboard to a slot canyon or normally dry wash. If you do still
decide to recreate, check in at a nearby visitor center or ranger
station.

People planning river trips on the Colorado River between Glen
Canyon Dam and the west end of Grand Canyon National Park should be
aware of the possibility of Flash Flooding from the side canyons and
plan accordingly.

The White Sage and Dragon Bravo fire burn scars will be especially
susceptible to Flash Flooding.  Use extreme caution if working in or
around these areas.
