An air quality advisory is in effect for West Michigan through Wednesday and Thursday, July 30-31.
According to AirNow.gov, 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. The advisory is due to smoke from Canadian wildfires moving into the Upper Peninsula Tuesday and into parts of the northern Lower Peninsula Wednesday morning with hourly PM2.5 concentrations ranging from USG to Unhealthy.
“Smoke from Canadian wildfires moved into the Upper Peninsula Tuesday and into parts of the northern Lower Peninsula Wednesday morning with hourly PM2.5 concentrations ranging from USG to Unhealthy,” said Stephanie M. Hengesbach, Meteorology Specialist, Air Quality Division, Michigan Department of Environment, Great Lakes, and Energy.
“Models show the plume continuing its southern trek across the state as a cold front moves south into the Ohio River Valley. 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.”
Sensitive groups are encouraged to take precautions.
This forecast will be evaluated Thursday morning to determine if the current statewide air quality advisory will need to be extended into Friday.
EGLE recommends:
- When possible, 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.
- Keep windows closed overnight to prevent smoke from getting indoors and, if possible, run central air conditioning with MERV-13 or higher rated filters.
How air quality is measured
Air quality is an important measure for creating desirable communities and protecting public health. Air Quality Advisories and Air Quality Alerts are based on the Air Quality Index (AQI).
The AQI is a scale from 0 to 500 that indicates air pollution levels. Higher values mean higher pollution and more health risks. When AQI exceeds 100, it is unhealthy, starting with sensitive groups and worsening as it rises. There are six categories, each with a color, to easily gauge the level of health concern in communities.
Air quality advisories/alerts information:
Air Quality Advisory: Issued when ground-level ozone, particulate matter (PM2.5) or both are expected to reach or exceed the Unhealthy for Sensitive Groups (USG) threshold. Those considered in the “USG” threshold include people with lung disease (such as asthma), children, older adults, people who are active outdoors (including outdoor workers), people with certain genetic variants, and people with diets limited in certain nutrients should reduce prolonged or heavy outdoor exertion.
This is aimed to provide awareness for poor air quality, encourage people to limit activities that contribute to poor air quality, and to alert those who are especially sensitive to poor air quality.
Air Quality Alert: Issued when Ozone, PM2.5, or both are expected to reach or exceed the Unhealthy threshold or worse. This alert indicates a higher level of concern as everyone, not just sensitive groups, can be affected by poor air quality.
