The Eastgate Regional Council of Governments (Eastgate) has issued an Air Quality Alert for May 20th in Mahoning and Trumbull Counties. Eastgate says the region is likely to experience ground-level ozone pollution levels that are unhealthy for sensitive groups in the national Air Quality Index (AQI) scale.

"Active children, the elderly, and people with asthma and COPD are more likely to suffer an increase in the number and severity of symptoms during an Air Quality Alert. To decrease the potential for health issues, sensitive groups of people are urged to limit prolonged outdoor activity or plan outdoor activities for the morning," says Justin Mondok, a Transportation Planner for Eastgate.

Sunny skies and temperatures climbing into the upper-80s will support ozone formation as the ridge of high pressure strengthens across Ohio. In addition, light southeasterly winds will transport regional pollutants into the Mahoning Valley. Therefore, AQI levels will be Unhealthy for Sensitive Groups. Friday, the upper-level ridge will continue to support ozone formation over Northeast Ohio as warm and sunny conditions persist. Light southwesterly winds will also transport regional pollutants into the area, leading to High-Moderate AQI levels.

To help improve air quality, Eastgate recommends everyone tries to take the following actions

  • Drive less by biking, walking, using transit, working from home, and combining trips
  • Use Gohio Commute (, a free tool that can help find carpool partners and discover air quality friendly transportation modes
  • Turn off your engine instead of idling your vehicle
  • Avoid refueling your vehicle or wait until after sunset
  • Avoid mowing your lawn on alert days
  • Avoid being outside for extended periods of time
