...AIR QUALITY ADVISORY IN EFFECT UNTIL 6 AM EDT SATURDAY MAY 31...

The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) has declared an Air Quality Advisory until 6 AM EDT, for
elevated levels of fine particulate (PM2.5) across the state of
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
far southern Michigan...

Berrien, Cass, St. Joseph, Branch and Hillsdale.

A cold front moving down from Ontario will bring wildfire smoke
plumes for fires in the provinces of Manitoba and Saskatchewan into
the state. The smoke plumes and associated increased PM2.5 will sink
across the state into Saturday morning. Increased vertical mixing
associated with the boundary will likely bring smoke to the surface.
As a result, we anticipate PM2.5 levels rising into the Unhealthy for
Sensitive Groups range across the state. There is a possibility that
hourly levels could reach the Unhealthy (Red AQI) range for a short
period of time.

It is recommended that, when possible, you avoid strenuous outdoor
activities, especially those with heart disease and respiratory
diseases like asthma. Monitor for symptoms such as wheezing,
coughing, chest tightness, dizziness, or burning in nose, throat,
and eyes.

Reduce or eliminate activities that contribute to air pollution,
such as:
 * outdoor burning,
 * use of residential wood burning devices.

Tips for households: Keep windows closed overnight to prevent smoke
from getting indoors and, if possible, run central air conditioning
with MERV-13 or higher rated filters.
