LEESBURG, OHIO — A dangerous heat wave has settled over Ohio, prompting the National Weather Service to issue a heat advisory through at least Wednesday evening. With temperatures climbing into the mid-90s and heat index values expected to reach as high as 104 degrees, residents across Highland County and surrounding areas are being urged to take immediate precautions.
“Extreme heat is responsible for the highest number of annual deaths among all weather-related hazards,” the Ohio Committee for Severe Weather Awareness warned in a joint statement with the Ohio Emergency Management Agency. “We urge all Ohioans to stay hydrated, limit outdoor activity, and check on neighbors and loved ones.”
The advisory covers much of the state, including Leesburg and the greater Tri-State area. According to meteorologist Jennifer Ketchmark of WCPO’s 9 First Warning Weather team, “We’re looking at heat index values between 100 and 105 degrees each afternoon through midweek.” Overnight lows in the 70s will offer little relief, increasing the risk of heat-related illnesses.
Local officials are encouraging residents to stay indoors during peak afternoon hours, wear light-colored clothing, and drink plenty of water—even if they don’t feel thirsty. Cooling centers have been opened in several counties, and emergency services are on high alert. Pet owners are reminded to ensure animals have access to shade and fresh water.
The Ohio Department of Health has also issued guidance on recognizing symptoms of heat exhaustion and heat stroke. Signs of heat exhaustion include heavy sweating, dizziness, and nausea. Heat stroke, a life-threatening condition, may involve a body temperature over 103°F, confusion, and loss of consciousness. Anyone experiencing these symptoms should seek immediate medical attention.
Scattered pop-up storms may develop in the afternoons, but they will be isolated and offer only brief relief. The heat advisory is currently set to expire at 8 p.m. Wednesday, though forecasters warn it could be extended if conditions persist.
