creeks, streams, dry washes, slot canyons, and other low-lying and
flood-prone locations such as slickrock areas and recent burn
scars.

* ADDITIONAL DETAILS...
- Deep moisture will remain in place across the region. Several
disturbances will fuel development of thunderstorms with rainfall
rates in excess of 0.25 to 0.50 inches per hour.  In areas with
training thunderstorms, rainfall rates will exceed 0.50 inches
per hour. This will cause flash flooding in areas such as
normally dry washes, slot canyons, and slickrock areas.
