‘Dangerously hot’ heat expected to take over in Southern Utah

ST. GEORGE, Utah (ABC4) — The first real heat wave of the summer will be taking over Southern Utah this week, bringing “dangerously hot” temperatures to the lower valleys.

The heat is expected to hit much of Washington County, including cities such as St. George, Hurricane and Ivins. The National Weather Service said southern Utahns can expect highs in the triple-digits, which is about 20 degrees higher than the seasonal norms.

The first triple-digit day could come as early as Tuesday, June 4 or Wednesday, June 5, according to ABC4’s 4Warn Weather Team. Daytime highs could climb up to 109 degrees on Thursday, which would break the previous record high of 107 degrees for June 6, set in 2016.

As a result of the expected heat wave, the National Weather Service issued an Excessive Heat Warning for much of Washington County, as well as the Glen Canyon Recreation Area and Lake Powell.

Temperatures in southern Utah are expected to stay warm throughout the night, only falling into the mid-70s, meaning there won’t be much relief from the heat.

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors,” the National Weather Service advised.

Residents are also advised not to leave young children or dogs unattended in cars as temperatures inside could reach “lethal levels” in minutes.
