rainfall, will continue through the morning hours across much of
central and southern Utah. Scattered showers and thunderstorms
capable of producing very heavy rainfall will again be possible
this afternoon and evening across the area.
* Heavy rainfall can lead to rapid onset of flooding, with some
of the most prone areas being slot canyons, burn scars,
normally dry washes, and low water crossings. Water can rise
quickly downstream of heavy rain, even when the actual
thunderstorm is many miles away. Rock and mud slides, as well
as water flowing across roadways, will be possible and could
locally impact travel.

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION.
