St. George, UT – Residents and visitors in southern Utah are facing one of the hottest days of the year as an Extreme Heat Warning remains in effect for Lower Washington County and Zion National Park through 10 p.m. Monday.
According to the National Weather Service Salt Lake City, dangerously high temperatures around 110 degrees are expected to continue this evening before cooling slightly into the low 100s by 9 p.m. The warning impacts communities including St. George, Hurricane, Springdale, and Ivins.
Health officials emphasize that the risk of heat-related illnesses such as heat exhaustion and heat stroke increases significantly during extreme heat events. The National Weather Service is urging everyone to drink plenty of fluids, stay in air-conditioned rooms when possible, and avoid direct sunlight. Residents are also reminded to check on relatives and neighbors, especially those who are elderly or vulnerable.
Leaving children or pets in vehicles—even for a short time—is especially dangerous during extreme heat, as interior temperatures can become lethal within minutes, officials said.
Authorities recommend limiting outdoor activities to early morning or evening hours, wearing lightweight and loose-fitting clothing, and taking extra breaks in shaded or air-conditioned environments. For those working outside, frequent rest and hydration are advised. Anyone experiencing symptoms of heat exhaustion or heat stroke should seek immediate medical attention.
Travelers are encouraged to monitor local traffic and weather updates, as heat conditions can affect travel plans and safety. Up-to-date information can be found at weather.gov/saltlakecity and udottraffic.utah.gov.
