...FLASH FLOOD WATCH REMAINS IN EFFECT UNTIL MIDNIGHT MDT
The Flash Flood Watch continues for
* Portions of central Utah and southern Utah, including the
following areas, in central Utah, Castle Country, Central
Mountains, San Rafael Swell, Sanpete/Sevier Valleys, Wasatch
Plateau/Book Cliffs, and West Central Utah. In southern Utah,
Glen Canyon Recreation Area/Lake Powell, South Central Utah,
Southern Mountains, Southwest Utah, and Utahs Dixie and Zion
* Until midnight MDT tonight
* Scattered showers and thunderstorms will continue to develop
across central and southern Utah the rest of this afternoon and
evening. Many of these storms will be capable of producing very
heavy rainfall, which may result in flash flooding.
* 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.
You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
