METRO DETROIT (WWJ) - Smoke from Canadian wildfires is expected to blow over Southeast Michigan once again on Wednesday, prompting officials to declare an Air Quality Alert due to elevated levels of ozone.
The Michigan Department of Environment, Great Lakes and Energy has declared Wednesday, June 21, as a Ozone Action Day as officials expect ozone concentrations to fall into the Moderate category.
The Air Quality Alert encompasses Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw and Wayne Counties.
Pollutants are forecasted to be unhealthy for sensitive groups, which include children, the elderly, people with respiratory conditions and those who work, exercise or play strenuously outdoors.
"As smoke threat diminishes somewhat, ozone is back on the radar," the EGLE said in an update on their website. "Michigan experienced some widespread higher ozone concentrations during Monday and a scattered few on Sunday... it is clear that we are seeing elevated numbers, even with the eastern wind."
The forecast remains mostly unchanged for Wednesday with hot temperatures, dry conditions and easterly winds expected. A shower or two could impact the area later in the day.
"With the persistent dry weather, fires and smoke will continue to be a concern on top of the current ozone threat," the EGLE added.
EGLE) declares an Ozone Action Day when weather conditions are likely to combine with pollution emissions to form high levels of ozone near the ground.
When in the stratosphere, officials said the ozone layer acts as a shield and protects earth from harmful ultraviolet rays, but it's a different story when ozone builds lower in the atmosphere.
"At ground level, excess ozone is a human health threat, causing lung problems and eye irritation," Oakland County health officials explained on their website.
Weather experts urge people and businesses to avoid activities which lead to ozone formation. The following activities are recommended for cleaner air:
• Refuel vehicles, lawn equipment and gas cans carefully.
• Avoid topping off the tank and be sure to lift the hose high to avoid spilling gas when finished.
• Choose to refuel after 6 p.m. when the air is cooler and ozone formation is less likely.
• Reduce automobile use and improve fuel consumption.
• Avoid excessive engine idling because excessive idling emits more pollutants than restarting a warm motor.
• Using water based paints.
• Combine trips or consider car and van pools or public transit for commuting or enjoy the day by choosing to ride a bicycle or walk to various errands and activities.
• Stay Informed.
Ozone Action Days are announced during most weather reports through local news outlets. You can stay tuned to WWJ LIVE as the week progresses to stay up-to-date on any new Air Quality Alerts.
