Record Breaking Heat in the Southwest

A powerful heat wave continues to grip the Southwest, with dangerously high temperatures impacting much of Arizona, southeastern California, and parts of southern Nevada. This brought record heat for Father's Day, where numerous cities broke heat records across the region.

Cities like Tucson, Phoenix, and Gila Bend are experiencing highs between 108°F and 114°F. The heat is especially intense in deserts and low-elevation areas, where overnight temperatures remain elevated, offering little relief. This prolonged heat is increasing the risk of heat-related illnesses, particularly for vulnerable populations and those without access to cooling.

The extreme heat is forecast to persist through Tuesday, with some areas potentially seeing continued elevated temperatures into Wednesday. While a slight cooling trend may begin midweek, the National Weather Service warns that heat risks will remain high, especially in desert regions. The Heat Risk tool continues to show “major to extreme” risk levels, indicating that even healthy individuals could be affected without proper precautions.
