Canadian Forest Fires Show in Hazy Ohio Day


OHIO – Have you noticed that today that the sky isn’t as clear as it usually has been seems overcast. What you are seeing is smoke from large forest fires from Canada

Smoke has filled the air across the Northeast Border of Canada and has expanded to parts of Ohio on Tuesday. The Mid-Ohio Regional Planning Commission (MORPC) is issuing an Air Quality Alert for Tuesday, June 6. The region – Delaware, Fairfield, Franklin, and Licking counties – is likely to experience PM2.5 or particle pollution levels that are Unhealthy for Sensitive Groups on the national Air Quality Index (AQI).

A cold front will move across central Ohio, shifting winds to northerly to northwesterly. These winds will carry dense smoke from eastern Canadian wildfires into the region, further increasing particle levels. Additionally, partly sunny skies and temperatures in the low-80s will aid ozone formation. As a result, AQI levels will be Unhealthy for Sensitive Groups.

Wednesday, moderate northerly winds will persist. While these winds will aid dispersion, they will also continue to carry smoke into Central Ohio. These conditions, combined with carryover from the previous days, will result in high-Moderate AQI levels.

MORPC uses the national AQI scale to inform the public about daily ozone and particle pollution levels in Central Ohio. The AQI scale runs from 0-500 – the higher the AQI value, the greater the health concern. When levels reach above 100, air quality is considered Unhealthy for Sensitive Groups, and MORPC issues an Air Quality Alert to the public.

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 are urged to limit prolonged outdoor activity or plan outdoor activities for the morning. Those who are experiencing breathing difficulties should consult their doctor. More information on the health effects of particle pollution is available from the U.S. EPA at AirNow.
