ORIGINAL STORY: Utah expecting another round of severe weather Wednesday

WEDNESDAY 8/18/2021 10:27 a.m.

SALT LAKE CITY (ABC4)- As many wake up and see the stormy clouds and conditions, Utahns can also expect to see another round of severe weather and possible severe thunderstorms for parts of the Beehive State again Wednesday.

The same parent system is still churning over Idaho and the interior Northwest as it makes its way east giving us the ample energy and moisture to have some strong to severe storms in Utah. These storms are also still expected to produce quite a lot of rain as we still have the flash flood watch in effect until midnight.

A large portion of Utah is under a slight risk for severe weather again today. Our main threats still are strong winds and damaging hail.


Strong gusty winds thanks to strong thunderstorms are expected throughout the day which can cause damage especially to trees and light poles as the soaked ground becomes softer. We could also see the threat for some damaging hail in the stronger storms also.


Storms will produce large amounts of rain and due to the heavy rains from yesterday the ground will not be able to hold much more moisture. This will cause all runoff to cause the usual areas such as burn scars, slot canyons, small creeks and streams, and dry washes to flood quickly.
