A flood watch is in effect through Thursday evening across much of southern and eastern Utah. Widespread moderate and locally heavy rainfall will bring many normally dry washes, slot canyons, and streams to run high and fast, while embedded heavy rainfall may result in more significant flash flooding. Backcountry roads across southern Utah may become impassible due to flood waters.
Widespread showers and thunderstorms are ongoing across southwest Utah Thursday morning, with pockets of flash flooding. Showers and thunderstorms are forecast to expand north and east through the morning and afternoon, with an associated expansion in flash flood risk.
A Marginal Risk (Level 1 of 5) for severe thunderstorms exists across much of southern and western Utah on Thursday. Storms will be capable of producing large hail, damaging wind gusts, heavy rainfall, and perhaps a brief tornado.
