by Stephanie CrosbyAn Air Quality Alert has been issued for the Louisville area for tomorrow. Air Pollution Control District spokesperson Matt Stull says it’s the first alert of the year, and it’s coming earlier than usual.He says the levels of ozone are expected to be dangerous for some people who are sensitive to air pollutants – such as children, the elderly and the chronically ill.“It’s kind of doubly-hard for a lot of people because pollen levels are already up, and I know a lot of people who suffer with allergies and asthma as a result of the allergies, they’ve having a tough way to go," says Stull. "So we’re really urging them to take care over the next couple of days to maybe limit their activity to the early morning or late in the evening.”Stull says the city’s first air quality alert is coming earlier than usual because of the unseasonably warm temperatures and stagnant air. Last year’s first air quality alert came in late May.
