Des Moines, Iowa – Iowa is facing a scorching heat wave, with heat indices reaching up to 105°F in cities like Des Moines, Ames, and Carroll on Wednesday. Residents across central and southern Iowa should brace for high humidity, with actual temperatures climbing into the low to mid-90s by late afternoon and evening.
Heat Advisory in Effect
The National Weather Service in Des Moines has issued a statewide heat advisory, which will remain in effect from 12 p.m. to at least 8 p.m. Wednesday. The agency warns that heat-related illnesses, such as heat exhaustion or heat stroke, are possible—particularly for those who spend extended periods outdoors or work without shade or regular breaks. Cities like Des Moines, Fort Dodge, Marshalltown, and Ottumwa will experience heat index values between 102°F and 105°F, with most of Iowa experiencing temperatures above 95°F for several hours.
Potential Risks and Community Response
In addition to the extreme heat, key highways like I-35 and I-80 may face heat-related pavement issues, and emergency response calls are expected to rise. Some cities, such as Mason City, Carroll, and Waterloo, may open cooling centers for residents looking to escape the heat. Schools and childcare centers are advising parents to keep children indoors during peak heat hours, while utility companies recommend reducing power consumption and staying hydrated.
How to Stay Safe During the Heat
If you must go outside, it’s essential to stay hydrated by drinking extra water, take frequent breaks in the shade, and avoid being outside during the hottest parts of the day. Never leave children or pets in vehicles, even for a brief time, as temperatures can rise dangerously fast. Those with chronic illnesses or without air conditioning are especially at risk for heat exhaustion or heat stroke, so it’s important to take extra precautions.
