MADISON, WI — An extreme heat warning has been issued for southern Wisconsin as high temperatures and heavy humidity combine to create hazardous conditions. The warning covers a stretch of the state where the heat index could climb to around 105 degrees.
Officials say the heat may be especially dangerous for people without air conditioning or other reliable ways to cool down. The warning is meant to alert residents to limit exposure and take the weather seriously.
Dangerous afternoon conditions
The warning centers on the hottest part of the day, when the combination of temperature and humidity can make it feel much hotter than the thermometer reading. That kind of heat can increase the risk of heat illness quickly, especially for people working or spending time outdoors.
Residents are being urged to drink water, take breaks in the shade, and check on neighbors who may be more vulnerable. The warning reflects the expectation that conditions could remain oppressive through the afternoon and evening.
Who faces the biggest risk
People without access to air conditioning are among those most at risk during an extreme heat warning. Older adults, young children, and anyone with health concerns can also be more vulnerable when temperatures and humidity stay high.
Officials are also concerned about people who spend long periods outside, including workers and those attending outdoor activities. The warning is intended to help residents plan ahead and avoid the most intense heat when possible.
Staying safe in the heat
Simple precautions can help reduce the chance of heat-related illness. Those include staying hydrated, avoiding unnecessary outdoor exertion during the hottest hours, and using air-conditioned spaces whenever possible.
Officials also advise paying attention to signs of heat exhaustion or heat stroke, which can become serious quickly in extreme conditions. The warning remains in place as southern Wisconsin deals with a stretch of dangerous summer heat.
