Weather warnings and advisories

A hazardous weather outlook is in place for the areas of Utah’s Dixie, Zion National Park, Glen Canyon Recreation Area, Lake Powell and Southern Utah mountains.

Strong easterly canyon winds will continue along portions of the northern Wasatch Front Friday morning, with the strongest winds expected near Farmington Canyon. This may impact travel along some north to south oriented routes.

In addition, moderate to heavy rain will continue Friday morning across Southern Utah, transitioning to showers and thunderstorms Friday afternoon. Heavy rain, gusty winds, small hail and lightning are possible with any storms that develop.

Warming temperatures will accelerate snowmelt at middle and higher elevations during the weekend. This will lead to streams and rivers running high, fast and cold across the outlook area through the remainder of the spring.

A flood advisory also remains in effect until 9 a.m. Friday for southern Washington County, where heavy rainfall was detected early Friday morning.

This heavy rain will continue to cause urban and small stream flooding in the advisory area. Area rivers and streams will continue to run high, as well as normally dry washes.

According to the National Weather Service, areas that are susceptible to flooding include St. George, Washington, Hurricane, Santa Clara, La Verkin, Ivins, Toquerville, Leeds, Virgin, Motoqua, Pintura, Bloomington, Gunlock, Veyo, Snow Canyon State Park and Goldstrike.
