ST. GEORGE — The National Weather Service in Salt Lake City has issued a wind advisory that will be in effect Thursday from 9 a.m. to 10 p.m.
Winds are expected to be 25 to 35 mph with gusts up to 55 mph. They will develop mid-morning and increase through the afternoon before diminishing in the evening.
Affected areas are south central Utah, the Wasatch Front, western and central Utah valleys, Castle Country and the San Rafael Swell, as well as the Great Salt Lake, Utah Lake and Lake Powell.
A wind advisory means that sustained wind speeds of at least 31 mph or gusts of 45 mph are expected, according to the weather service.
Motorists in the advisory area should be prepared for sudden gusty cross winds which can make driving difficult, especially for high profile vehicles and those towing trailers on east-west routes, including interstates 80 and 70, and highways 6 and 50.
The strong winds will create dangerous boating conditions on area lakes. Those winds will create choppy water and generate large waves that could capsize or swamp small craft. For your personal safety, operators of small craft are urged to postpone their outings until the winds subside, the weather service advises.
