Warning in Effect Now

An Extreme Heat Warning is currently in effect for a broad stretch of Minnesota, covering the following areas: North Itasca, Norman, West Polk, Wabasha, Houston, Goodhue, Hennepin, Douglas, Stearns, Stevens, Sibley, and Traverse. The warning was issued on July 26, 2026 at 4:18 PM CDT and remains active until 9:00 PM CDT on July 26, 2026. Residents in all listed counties should treat this alert as active and take immediate protective measures.

The warning was issued jointly by multiple National Weather Service offices, including NWS Duluth MN, NWS Grand Forks ND, NWS La Crosse WI, NWS Twin Cities/Chanhassen MN, and NWS Aberdeen SD, a coordinated response that underscores how widely this heat event is being felt across the region.

What NWS Is Telling You to Do Right Now

The National Weather Service is issuing direct, specific guidance for anyone in the affected areas during this warning window. Officials are instructing residents to drink plenty of fluids, get into an air-conditioned room, stay out of the sun, and actively check on relatives and neighbors. That last point matters: not everyone in these counties will have easy access to cooling, and a personal check-in with an elderly neighbor or a family member who lives alone can be a life-saving action during an event like this.

NWS is also issuing a firm warning about vehicles: do not leave young children or pets in unattended cars. The National Weather Service states explicitly that car interiors can reach lethal temperatures in a matter of minutes. This is not a cautionary estimate, it is a documented, recurring cause of preventable deaths during heat events. If you are traveling with children or animals on July 26, 2026 during this warning period, they must exit the vehicle with you every time you stop.

The official NWS message closes with three clear directives: stay cool, stay hydrated, stay informed. Each of those is an action, not just a slogan. Staying informed means monitoring NWS updates through the warning expiration at 9:00 PM CDT and being ready to act if conditions change or the warning is extended.

Putting This Alert in Context

Extreme Heat Warnings represent one of the more serious tiers of weather alerts issued by the National Weather Service, and they serve as a direct signal for residents to change their behavior, not simply to be aware. For households that already have a basic disaster-preparedness plan in place, an event like this is exactly the scenario that plan is designed for: knowing where your nearest cooling center is, keeping water accessible, and having a short list of vulnerable people in your life to check on. If those pieces aren’t in place yet, this warning is a useful prompt to build them before the next heat event arrives.
