Tucson, AZ – Dangerous heat and the potential for strong to severe thunderstorms are expected across southeast Arizona Saturday, creating a combination of weather hazards that could impact outdoor activities and travel.
According to the National Weather Service in Tucson, much of southeast Arizona is under a Major to Extreme HeatRisk Saturday, with dangerously hot conditions expected during the afternoon. Residents are urged to limit time outdoors, stay well hydrated, and take frequent breaks if they must work or spend time outside.
Forecast highs are expected to climb well above 100 degrees across much of the region, with temperatures reaching around 108 degrees in Tucson, 116 degrees in Phoenix, and 111 degrees in areas including Gila Bend, Eloy, and Marana. Even mountain communities are expected to experience above-normal heat.
Later in the day, scattered thunderstorms are expected to develop across portions of southeast Arizona. While storm coverage is expected to remain scattered, some storms could become strong to severe, producing damaging wind gusts, frequent lightning, and locally heavy rainfall capable of creating hazardous travel conditions and localized flooding.
The National Weather Service recommends avoiding strenuous outdoor activities during peak afternoon heat, drinking plenty of water, and checking on vulnerable family members and neighbors. Motorists should also remain alert for rapidly changing weather conditions, including sudden reductions in visibility from blowing dust near thunderstorms and water-covered roadways where heavy rain develops.
Residents are encouraged to monitor the latest forecasts throughout the day, as thunderstorm coverage and intensity may change with evolving weather conditions.
