Warning in Effect Now: Eight Minnesota Counties Under Extreme Heat Alert
An Extreme Heat Warning is currently in effect for eight Minnesota counties: Douglas, Stevens, Hennepin, Stearns, North Itasca, Wabasha, Winona, and Norman. The warning became active on Saturday, July 25, 2026, at 3:33 PM CDT and is set to expire on Sunday, July 26, 2026, at 9:00 PM CDT. The alert was issued by multiple National Weather Service offices. NWS Twin Cities/Chanhassen MN, NWS Duluth MN, NWS La Crosse WI, and NWS Grand Forks ND, reflecting the broad geographic reach of this dangerous heat event across the region. Residents in any of these eight counties should treat this warning as active through Sunday evening and take protective action accordingly.
What the National Weather Service Is Telling You to Do Right Now
The National Weather Service is urging residents across the affected counties to take immediate, practical steps to protect themselves and others. The core guidance is straightforward: drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. These are not optional precautions during an Extreme Heat Warning, they are the actions that prevent life-threatening outcomes.
One of the most urgent points in the NWS alert concerns vehicles. Do not leave young children or pets in unattended cars. The National Weather Service warns that car interiors can reach lethal temperatures within a matter of minutes. This applies even with windows cracked, even in shaded parking areas, and even for a “quick” errand stop. If you see a child or animal left alone in a vehicle in these conditions, treat it as the emergency it is.
For anyone who must be outside, the NWS instructs residents to wear lightweight and loose-fitting clothing, and to try to limit strenuous activities to early morning or evening hours when heat is less intense. Knowing the warning signs of heat exhaustion and heat stroke, and acting on them immediately, is critical. If someone shows symptoms of heat stroke, move them to a cool, shaded location right away and call 9-1-1. Heat stroke is a medical emergency.
The alert also carries specific guidance for outdoor workers. The National Weather Service references Occupational Safety and Health Administration recommendations, advising that employers schedule frequent rest breaks in shaded or air-conditioned environments. No task is worth a heat-related fatality. Anyone overcome by heat on a worksite should be moved to a cool and shaded location immediately, and emergency services should be contacted without delay.
Disaster Preparedness Context: Heat Is One of the Most Underestimated Hazards
Extreme heat is consistently one of the leading causes of weather-related deaths in the United States, yet it often receives less public attention than more visually dramatic events like tornadoes or floods. Alerts like this one from the National Weather Service exist precisely because heat danger can escalate quickly and quietly. At USRiskRadar, our guidance on heat preparedness emphasizes the same fundamentals the NWS outlines here: know your local alert system, have a plan for staying cool if your home lacks air conditioning (public cooling centers are a key resource), and make a habit of checking on elderly neighbors and family members during extreme heat events. The warning covering Douglas, Stevens, Hennepin, Stearns, North Itasca, Wabasha, Winona, and Norman counties is a live, active alert, residents should stay informed through official NWS channels and local emergency management for any updates before Sunday evening.
