Smog Advisory Lifted

Effective immediately, the Ministry of the Environment has lifted its Smog Advisory for the following forecast regions:

Windsor-Essex-Chatham-Kent

Cleaner air is expected as a weak cold front moves southeastward across the province.

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.
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 (PM2.5).
Smog is harmful to the lungs and heart. Even in healthy people, smog can reduce lung function.
