Notice of Smog Advisory

NEWS

The Ministry of the Environment is issuing a Smog Advisory for tomorrow, June 24, for the following forecast region:

Windsor-Essex-Chatham-Kent

Hot, sunny conditions combined with light and variable winds are expected to result in the build-up of pollutants across the extreme southwestern part of Ontario.

This advisory will remain in effect until further notice.

QUICK FACTS

• A Smog Advisory is related to the Air Quality Index (AQI), which rates how clean the air is. The AQI scale ranges from 0 to 100+. Higher numbers mean higher health risks.
• A Smog Advisory is issued in your region when the AQI is expected to reach 50 in the next 24 hours. It can be lifted once the AQI is expected to or drops below 50.
• Smog is made up of a complex mixture of air pollutants, sometimes visible, such as a brownish-yellow haze over cities; sometimes not. The two main ingredients of smog are ground-level ozone (O₃) and fine particulate matter (PM_2.5).
• Smog is harmful to the lungs and heart. Even in healthy people, smog can reduce lung function.
