WEATHER ALERT
Issue Date: 859 PM MST Sun Aug 2 2026
BLOWING DUST ADVISORY IN EFFECT FROM 2 PM TO 8 PM MST MONDAY
EXTREME HEAT WARNING REMAINS IN EFFECT UNTIL 8 PM MST MONDAY
WHAT
Thunderstorms will initially develop over the Mogollon Rim and other sky islands of Southeast Arizona during the early afternoon hours, then track southwest into the valleys of Southeast Arizona and become widespread during the late afternoon and early evening. The stronger storms will produce organized thunderstorm outflow winds between 40-50 mph, resulting in dense blowing dust with visibility between one-half and one mile and possibly a haboob with near-zero visibility. For the Extreme Heat Warning, dangerously hot conditions with temperatures 101 to 106 in Santa Cruz and Cochise counties and 107 to 112 elsewhere. Major to Extreme HeatRisk is expected. WHERE
Eastern Cochise County below 5000 feet, Tucson Metro Area, Upper Gila River Valley, Upper San Pedro River Valley, and Upper Santa Cruz River Valley/Altar Valley. WHEN
For the Extreme Heat Warning, until 8 PM MST Monday. For the Blowing Dust Advisory, from 2 PM to 8 PM MST Monday. IMPACTS
Hazardous driving conditions due to reduced visibility. Heat related illnesses increase significantly during extreme heat events. ADDITIONAL DETAILS
Warm overnight low temperatures of 84 to 90 degrees in the deserts will provide little to no relief from heat overnight. Warmest overnight low temperatures expected in the Western Deserts.
PRECAUTIONARY/PREPAREDNESS ACTIONS
Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1. Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible and drink plenty of water. &&
