Columbus, Ohio – Sweltering heat will again grip Central Ohio on Tuesday, with heat index values soaring past 104°F, making outdoor activities dangerous. The National Weather Service has issued a Heat Advisory through 8 p.m. Wednesday, impacting much of Ohio, including Columbus and surrounding areas.
What to Expect on Tuesday
On Tuesday, temperatures in Columbus will reach a high near 97°F, but the oppressive humidity will make it feel like 105°F. The Heat Advisory covers Franklin, Delaware, Fairfield, Licking, Pickaway, and several other counties, where the combination of heat and humidity raises the risk of heat-related illnesses such as heat exhaustion and heat stroke.
Health and Safety Tips
With consecutive days of hot, humid air and little overnight relief, officials are urging residents to take extra precautions.
Avoid non-essential travel during peak heat hours, especially on major routes like I-70, I-71, and U.S. 23, where vehicle breakdowns could become dangerous. If you must go outside, wear loose clothing, stay hydrated, and take breaks in the shade or air-conditioned spaces. Schools and summer camps should adjust outdoor schedules to limit exposure to the heat. Minimize energy use in the late afternoon to reduce the risk of power outages.
Travel and Commute Risks
Travelers along major routes like I-71, I-70, and U.S. 23 should be cautious due to the extreme heat. Vehicle breakdowns could quickly turn into serious situations in these conditions. Officials advise limiting travel when possible and making sure your vehicle is well-maintained before heading out.
Relief on the Horizon
Scattered thunderstorms are expected by Tuesday afternoon and evening, offering some temporary relief, though the heat will quickly rebuild on Wednesday, with highs still expected in the mid-90s. The heat is expected to ease by Friday, but until then, the risk of heat-related illnesses remains high.
