...AIR QUALITY ADVISORY FOR WEDNESDAY JUNE 11...

The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) has declared an Air Quality Advisory for June 11, 2025, for
elevated levels of ozone in parts of southwest Michigan. Pollutants
within those areas are expected to be in the Unhealthy for Sensitive
Groups (USG, Orange AQI) range.

The Air Quality Advisory is in effect for the following counties in
southwest Michigan...

Berrien

Surface temperatures well into the 80s, ample sunlight, and west-
southwest winds will create a conducive environment for Ozone
development along the Lake Michigan shoreline. Residual wildfire
smoke in the region may also enhance Ozone development over Lake
Michigan.

It is recommended that, when possible, you avoid strenuous outdoor
activities, especially those with respiratory diseases such as
asthma.

People and businesses are urged to avoid activities which lead to
ozone formation. These activities include:
 * refueling vehicles or topping off when refueling;
 * using gasoline powered lawn equipment;
 * using charcoal lighter fluid.

Positive activities include:
 * driving less;
 * telecommuting;
 * walking or bike riding;
 * and delaying or combining errands;
 * using water-based paints.
