WHAT...The PM2.5 AQI is expected to reach the Unhealthy for
Sensitive Groups (USG) to Unhealthy level.
WHERE...All of Wisconsin.
WHEN...Until noon Thursday, July 31.
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 surface air
quality across the region through at least Thursday morning,
causing the PM2.5 Air Quality Index (AQI) to range from the
Unhealthy for Sensitive Groups (USG; Orange) category to the
Unhealthy (Red) category. It will be possible for NowCast AQI
values to reach the Very Unhealthy (Purple) category.
Smoke impacts continue to be observed across central and northeast
Wisconsin, with poor air quality and minor reductions in
visibility. Smoke is expected to linger across much of Wisconsin
into at least Thursday morning. We may see brief improvement in
air quality later Thursday before smoke moves back into northern
areas on Friday. Stay tuned to the air quality forecast as
conditions can change quickly during wildfire smoke events.

Air Quality Advisory for Michigan
Wednesday July 30th and Thursday July 31st
The Michigan Department of Environment, Great Lakes, and Energy (EGLE)
has issued an Air Quality Advisory for elevated levels of fine particulate
(PM2.5) across the state of Michigan. Pollutants across the state are expected
to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range Wednesday
and Thursday with some locations reaching the Unhealthy (Red AQI) range.
The Air Quality Advisory includes all Michigan counties.
Smoke from Canadian wildfires moved into the Upper Peninsula Tuesday and into
parts of the northern Lower Peninsula Wednesday morning. Models show the
plume continuing its southern trek across the state with smoke expected
to linger across the region through Thursday. As the smoke moves in, PM2.5
concentrations in the Unhealthy for Sensitive Groups (USG) range will
expand south, while concentrations of PM2.5 in the Unhealthy range are
more likely across northern areas.
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.
