A dangerous stretch of heat and humidity is set to peak in Louisville, Kentucky, on Thursday, July 24. With a heat index expected to reach 108°F across much of the state, residents should brace for both an Air Quality Alert and a Heat Advisory, which will overlap from 9 a.m. to 8 p.m. EDT.
The combination of heat, humidity, and poor air quality makes outdoor activities risky, especially for vulnerable groups.
Heat Advisory and Air Quality Alert in Effect
According to the National Weather Service and the Louisville Metro Air Pollution Control District, a Code Orange Ozone Alert will be in effect, indicating that the air quality will be unhealthy for sensitive groups such as children, the elderly, and people with respiratory conditions.
In addition to the heat advisory, which covers Jefferson, Bullitt, Oldham, and surrounding counties in southern Indiana and central Kentucky, residents should limit outdoor exposure, especially during peak heat hours.
What’s the Weather Like on Thursday?
Thursday will bring mostly sunny skies and scorching temperatures, with highs near 95°F. The combination of high temperatures and strong southwest winds will cause the heat index to surge above 105°F.
For those with asthma, heart conditions, or respiratory issues, it is important to avoid strenuous activities and stay indoors when possible. Roadways such as I-65 and I-64 may also be impacted by heat shimmer and potential pavement damage due to the extreme temperatures.
Tips to Stay Safe During the Heat
To stay safe during this heat wave, officials recommend staying hydrated, using air conditioning, and checking on vulnerable neighbors, particularly the elderly and those with health conditions. Outdoor workers should schedule breaks and wear light, breathable clothing to minimize the risk of heat-related illnesses.
