SALT LAKE CITY — A storm system that moved in from the West brought severe weather across Utah on Wednesday, with more still possible.
A Severe Thunderstorm Watch has been issued until 8 p.m. for all of western Utah and parts of Wyoming, while several Severe Thunderstorm Warnings were issued across northern Utah where residents were warned about wind gusts up to 60 mph and quarter-sized hail being possible.

However, the storm was expected to hit southern and central Utah the hardest and despite severe weather moving on from the northern part of the state, strong thunderstorms and flooding was still possible in certain areas.
Confidence increasing for severe weather in the north and excessive rainfall in the south today. In a rare combination, we have both a "moderate" risk for excessive rainfall and "slight" risk for severe thunderstorms in our area, and are gearing up for a busy day today. #utwx pic.twitter.com/dZen28dHlw— NWS Salt Lake City (@NWSSaltLakeCity) September 21, 2022
Flash flooding is "expected" in many Utah recreation sites including Arches National Park, Canyonlands National Park, and Capitol Reef National Park. In Zion National Park and Bryce Canyon National Park, flash flooding is "probable."
Visitors to these outdoor recreation sites will want to avoid the slot canyons and be aware of dry washes and small streams that are expected to experience flash flooding.
In addition to recreation areas, weather experts say areas near recent burn scars are likely to see flash flooding.
The National Weather Service advises that if you come across a flooded road, do not attempt to drive through it and outdoor recreators should consider making alternate plans for Wednesday.
