Louisville Experiences 12th Air Quality Alert

by Chris McDaniel on July 27, 2011

The Air Pollution Control District has issued an Air Quality Alert for Wednesday and Thursday in Louisville.

This is already Louisville’s 12th Air Quality Alert, compared to 19 all of last year.  There were only four the year before that.

“Especially with ozone, heat and sunlight are needed to form ozone at the ground level,” Matt Stull of the Air Pollution Control District said.   “So, when we see days with hot and humid conditions and combine that with stagnant air, you combine that with emissions from tailpipes, you have a buildup of ozone.”

With a weather forecast predicting more hot weather, it’s likely to cause more alerts.

“We’re looking at high temperature in the mid 90s and continuing on Thursday, maybe low 90s on Friday,” Ryan Sharp of the National Weather Service said.  “And Sunday Monday and Tuesday all look to be in the mid 90s.”

The air in Louisville is currently categorized as “unhealthy for sensitive groups.”  People with asthma, children and the elderly could be affected, and are encouraged to limit their time outdoors.
