Air Quality Forecast
Air quality forecasts are issued every day of the year for the Birmingham area and are based on the Air Quality Index (AQI). The AQI is a color-coded scale that reports how clean or polluted the air is and the associated health effects.
The Jefferson County Department of Health forecasts fine particles (PM2.5) year-round and the Alabama Department of Environmental Management forecasts Ozone (O3) during the warm season.
An Air Quality Alert is issued when the AQI is forecast to reach 101 or higher. The public is encouraged to decrease their personal emissions on days with higher pollution levels.
Saturday-Monday: A frontal boundary will continue to meander around northern Alabama over the weekend to create partly cloudy to overcast skies with scattered storms. Ridging will build into the area on Monday to clear the skies and end the chance for rain. PM2.5 is expected to be in the yellow range through Monday. Ozone is expected to be in the green range over the weekend and in the yellow range on Monday.
