The State Health Department issued an air quality alert on Wednesday, indicating there were “unhealthy” air conditions for sensitive groups.

The advisory applied to 5 counties in south central Oklahoma and along I-35.

It was the second such alert issued this week by the Department of Environmental Quality. The DEQ urged people with respiratory diseases to avoid smoke that has settled over the lower power of the U.S. from wildfires in Canada.
