...AIR QUALITY ALERT NOW IN EFFECT UNTIL NOON CDT MONDAY...

* WHAT...The Minnesota Pollution Control Agency has issued an Air
Quality Alert for fine particles pollution. The Air Quality Index
(AQI) is expected to reach the Red or Unhealthy category.

* WHERE...West central, east central, central, south central,
southwest, southeast, north central, northwest, and northeast
Minnesota.

* WHEN...Until noon CDT Monday.

* IMPACTS...Some members of the general public may experience
health effects. Sensitive groups, such as people with lung
disease (including asthma), heart disease, and children and older
adults, may experience health effects.

* ADDITIONAL DETAILS...Surface high pressure will camp out over
the region through Friday evening and will result in light winds
and poor dispersion. Smoke with widespread red/unhealthy air
quality index (AQI) concentrations will likely remain over most
of the state through tonight and into the day Saturday. Winds
will increase out of the south over the weekend as high pressure
drifts east of the area. Smoke concentrations should gradually
decline starting Saturday, but the clearing of the smoke may be
slow with smoke spreading as far south as Tennessee and Missouri.
Orange AQIs (unhealthy for sensitive groups) could hang on
through Sunday and into the day Monday. Most of the alert-level
smoke should push north back into Canada by later Monday.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Sensitive groups, such as people with lung disease (including
asthma), heart disease, and children and older adults, should
avoid prolonged or heavy exertion. The general public should
limit prolonged or heavy exertion.

Reduce or eliminate activities that contribute to air pollution,
such as outdoor burning, and use of residential wood burning
devices. Reduce vehicle trips and vehicle idling as much as
possible.

Keep windows closed overnight to prevent smoke from getting
indoors.

WHAT...The PM2.5 AQI is expected to reach the Unhealthy for
Sensitive Groups to Unhealthy level.

WHERE...All of Wisconsin.

WHEN...Until noon Saturday, August 2.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Sensitive groups: Consider rescheduling or moving all activities
inside. Go inside if you have symptoms.

People with asthma: Follow your asthma action plan and keep
quick-relief medicine handy.

People with heart disease: Symptoms such as palpitations,
shortness of breath, or unusual fatigue may indicate a serious
problem. If you have any of these, contact your health care
provider.

Everyone else: Keep outdoor activities shorter and less intense.
Go inside if you have symptoms.

Additional Details:
Canadian wildfire smoke will continue to impact Wisconsin`s
surface air quality over the next several days. Conditions have
improved since Thursday as a pocket of cleaner air has
infiltrated the widespread blanket of dense smoke across eastern
Wisconsin. However, a mix of Unhealthy for Sensitive Groups (USG;
Orange) AQI and Unhealthy (Red) AQI is still expected today, with
locations farther north more likely to see heavier smoke.
Continued gradual improvement is currently anticipated heading
into the weekend, but USG (Orange) AQI to Unhealthy (Red) AQI
will remain possible. Conditions will continue to be reevaluated
on a day-to-day basis, including updates to the forecast and any
associated Air Quality Advisories.

WHAT...The PM2.5 AQI is expected to reach the Unhealthy for
Sensitive Groups to Unhealthy level.

WHERE...All of Wisconsin

WHEN...Until noon Saturday, August 2

Precautionary/Preparedness Actions:
Sensitive groups: Consider rescheduling or moving all activities
inside. Go inside if you have symptoms. People with asthma:
