A heat wave that will linger over the region for the next several days will produce high temperatures in the triple digits.
That has health officials cautioning those who have to be outside to consume plenty of liquids and avoid overexertion.
University of Louisville Hospital emergency department physician Laura Tudor says low humidity levels will make coping with the heat a bit easier.
“The higher the humidity, the slower you’re able to kind of release that excess heat, so if the humidity is lower it definitely helps a little bit. But obviously if the temperature is over 100, you can still develop issues,” she said.
Louisville Metro Government says people can seek relief at Neighborhood Place locations, community centers, public libraries and Metro Parks pools and spraygrounds.
Operation White Flag is in effect at the city’s homeless shelters, meaning no one will be turned away during the extreme heat.
Louisville will be under an air quality alert Thursday, with ozone levels in the unhealthy range for sensitive groups such as children, the elderly and those with heart and lung ailments.
And Churchill Downs has cancelled its Thursday live racing card because of the heat. Racing will resume on Friday.
