INDIANA — A muggy midsummer airmass has prompted meteorologists at the National Weather Service in Indianapolis to issue a Heat Advisory for several southwestern and central Indiana counties.
The advisory takes effect at 11:00 a.m. and remains active through 8:00 p.m. With actual temperatures climbing into the lower 90s combined with elevated dew points, peak heat index values—how hot it feels to the human body—are projected to reach as high as 110 degrees Fahrenheit during peak heating hours.
The Heat Advisory encompasses a major corridor of southwestern and west-central Indiana: Lawrence, Daviess, Martin, Greene, Clay, Knox, Owen, Vigo, Sullivan.
The advisory area also includes surrounding regional hubs such as Bedford, Terre Haute, Vincennes, and Linton. Neighboring counties across central and south-central Indiana face similar oppressive heat levels through late evening.
Health Risks and Safety Guidance
Meteorologists warn that high temperatures paired with high atmospheric humidity drastically reduce the body’s ability to cool itself through sweat, significantly increasing the risk of heat-related illnesses such as heat exhaustion and heat stroke.
Public health officials recommend taking the following precautions during the afternoon hours:
- Hydrate Constantly: Drink plenty of fluids (water or electrolyte drinks) even if you do not feel thirsty. Avoid excessive alcohol or caffeine.
- Stay Indoors: Limit outdoor activity to early morning or late evening. Remain in air-conditioned environments during peak heat hours.
- Check on Vulnerable Neighbors: Regularly check up on elderly relatives, neighbors, and individuals without working air conditioning.
- Protect Pets and Children: Never leave children or pets unattended in parked vehicles under any circumstances. Car interiors can reach lethal temperatures in less than 10 minutes.
- Pace Outdoor Work: Outdoor workers are urged to take frequent rest breaks in shaded or air-conditioned areas and wear light-colored, loose-fitting clothing.
Heat Illness Symptoms to Watch For
| Condition | Symptoms | What to Do |
| Heat Exhaustion | Heavy sweating, weakness, cold/clammy skin, dizziness, nausea | Move to a cool place, loosen clothing, sip water. |
| Heat Stroke | High body temp (103°F+), confusion, hot/red skin, rapid pulse, fainting | Call 911 immediately. Move person to a cool area, use cool cloths. |
While heat indices peak late this afternoon, weather models indicate potential relief could come in the form of scattered afternoon and evening pop-up thunderstorms. However, localized severe gusts and heavy downpours may accompany any storms that do develop. Residents should stay tuned to local weather alerts throughout the evening.
