Tucson, Arizona – Dangerous heat will grip Southern Arizona starting Thursday, with temperatures soaring to 115 degrees Fahrenheit. Residents must prepare for extreme conditions, especially on Juneteenth. These high temperatures significantly increase the risk of heat-related illnesses.
According to the National Weather Service in Tucson, an Extreme Heat Warning remains in effect from 10 a.m. Thursday to 9 p.m. MST Friday. Portions of Santa Cruz, Pima, and Cochise counties below 5,000 feet will experience the most severe heat, including the Tucson metro area.

The Occupational Safety and Health Administration recommends frequent rest breaks in cool, shaded areas for outdoor workers.
