WATCH: Haze covers Dayton; Air Quality Alert today, Wednesday due to Canadian wildfire smoke

An air quality alert is in effect today and Wednesday due to wildfire smoke from Canada causing elevated air pollution levels.

Wildfire smoke shrouded the city of Dayton today, and a haze could be seen over Interstate 75 in Middletown.

The alert is for Clark, Darke, Greene, Miami, Montgomery and Preble counties, issued by the Miami Valley Regional Planning Commission and Regional Air Pollution Control Agency.

The air quality index forecast is 105 for Tuesday. Any reading of 101 or higher is considered “unhealthy for sensitive groups,” including children, older adults and people with cardiac or respiratory disease.

People in those groups should reduce prolonged time outdoors or heavy exertion due to the high levels of fine particles in the air, according to a statement from RAPCA.

The general public is not likely to be affected, but people generally should take more breaks and do less strenuous activities while the alert is in effect.

Tips to help reduce air pollution:

  • Avoid driving if possible. If not, combine errands or delay them until the air quality alert is lifted. While driving, avoid excessive idling, especially at drive-thru windows.
  • Refuel vehicles after 8 p.m., or wait until the alert is over. Make sure your gas cap is on tightly to avoid letting gas fumes escape.
  • Limit the use of gasoline-powered equipment around the home, such as lawn mowers, chainsaws, power trimmers and shredders.
  • Mow lawns after 6 p.m.

The National Weather Service in Wilmington said that the smoke caused hazy skies on Monday as winds from Quebec pulled it as far south as the Carolinas.
