ST. GEORGE – The National Weather Service out of Salt Lake City has issued a “Hazardous Weather Outlook” for the western two-thirds of Utah and southwest Wyoming for high temperatures 10 to 15 degrees above normal and an elevated threat of heat related stress.
Hot temperatures are expected across the outlook area Saturday with many valleys seeing readings near or above 100. Highs around 110 are forecast for the St. George area.
Remain alert to the hazards of excessive heat. The added stress can be dangerous, particularly for sensitive individuals.
Days two through seven, Sunday through Friday
The hot temperatures are expected to continue across most of the outlook area through the week with highs each day averaging 10 to 15 degrees above normal. This long stretch of hot weather will maintain an elevated threat of heat related stress.
The National Weather Service is advising those who work or spend time outside to take extra precautions. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible and drink plenty of water.

To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments.
“Anyone overcome by heat should be moved to a cool and shaded location,” according to the weather service. “Heat stroke is an emergency, call 911.”
