...AIR QUALITY ADVISORY FOR SUNDAY JUNE 22 AND MONDAY JUNE 23...

The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) has declared an Air Quality Advisory through for June 22 and
June 23, for elevated levels of ozone in western counties in
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 and Cass

We are in the peak of ozone season, and the current forecast shows
ozone-conducive conditions for Sunday and Monday. Surface
temperatures in the 90s, coupled with ample sunshine and southwest
winds, create an environment favorable for ozone development along
the Lake Michigan shoreline.

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;
 * delaying or combining errands;
 * using water-based paints.

...EXTREME HEAT WARNING IN EFFECT UNTIL 8 PM EDT /7 PM CDT/
TUESDAY...

* WHAT...Dangerously hot conditions with heat index values of around
  100 with a maximum up to around 105.

* WHERE...Portions of northern Indiana, southwest Michigan, and
  northwest Ohio.

* WHEN...Until 8 PM EDT /7 PM CDT/ Tuesday.

* IMPACTS...Heat related illnesses increase significantly during
  extreme heat and high humidity events, particularly if they
  persist for several days in a row.

* ADDITIONAL DETAILS...Cumulative effects of long-duration heat will
  likely cause significant impacts, especially since it is the first
  heat wave of the season. Low temperatures in the 70s will provide
  little relief, especially for vulnerable populations.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Drink plenty of fluids, stay in an air-conditioned room, stay out of
the sun, and check up on relatives and neighbors.

Take extra precautions when outside. Wear lightweight and loose
fitting clothing. Try to limit strenuous activities to early morning
or evening. Take action when you see symptoms of heat exhaustion and
heat stroke.

To reduce risk during outdoor work, the Occupational Safety and
Health Administration recommends scheduling frequent rest breaks in
shaded or air conditioned environments. Anyone overcome by heat
should be moved to a cool and shaded location. Heat stroke is an
emergency! Call 9 1 1.
