ST. GEORGE — The National Weather Service in Salt Lake City has issued a wind advisory for western Utah and Utah Department of Transportation has simultaneously issued travel alerts for Utah roads and highways; collectively, the cautions are in effect Wednesday through about 10 p.m.

Wind speeds are expected to be 20-30 mph, with gusts up to 50 mph, which may include crosswinds on area highways that motorists are urged to be mindful of.

An unseasonably cold upper level trough over the Pacific Northwest will create a strong and dry southerly flow across much of Utah Wednesday. A weak cold front advancing towards northwest Utah combined with this strong southerly flow will produce strong, gusty southerly winds over the western valleys beginning late Wednesday morning. The winds will continue into Wednesday evening.

Affected area

Salt Lake and Tooele valleys, southern Wasatch Front, Great Salt Lake Desert and mountains of west-central and southwest Utah. This includes the cities of Salt Lake City, Tooele, Lehi, Provo, Nephi, Wendover, Snowville, Delta, Fillmore, Beaver, Cedar City and Milford.

Timing

Winds will become strong Wednesday morning and remain strong through midevening Wednesday.
