Excessive heat warning issued for parts of southern Utah

SALT LAKE CITY — An excessive heat warning has been issued for parts of southern Utah, with temperatures approaching 109 degrees near Lake Powell and St. George.

The National Weather Service said the warning goes into effect at noon Thursday and lasts through 9 p.m. Friday.

“Extreme heat will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities,” NWS officials said.

Meteorologists added the area will see limited overnight cooling, with Friday morning lows as warm as the lower 80s in St. George and Lake Powell.

The warning covers lower Washington County, south-central Utah and Glen Canyon National Recreation Area/Lake Powell.

Arizona meteorologists on Monday issued an excessive heat warning for the Grand Canyon that was later expanded to include Page, Arizona, and the Glen Canyon/Lake Powell area.

Temperatures could range from 105 degrees near Page to 115 near Phantom Ranch in the Grand Canyon through Friday.

Wednesday’s high for Lake Powell near Page was forecasted to reach 106 degrees.

We have updated our Excessive Heat Warning to now include Glen Canyon in addition to the Grand Canyon for areas below 4500 feet. This warning has also been extended through Wednesday at 6:00 PM MST. Stay hydrated! #azwx pic.twitter.com/Sq8DiksnPq
