Air Quality Alert issued August 1 at 3:51PM CDT by NWS La Crosse WI

Non-Weather Emergency Message. Not sent to IPAWS.

* 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.

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.

The Wisconsin Department of Natural Resources has issued an Air Quality Advisory for the following counties: Adams, Buffalo, Clark, Crawford, Grant, Jackson, Juneau, La Crosse, Monroe, Richland, Taylor, Trempealeau, and Vernon. WHAT...The PM2.5 AQI is expected to reach the Unhealthy for Sensitive Groups to Unhealthy level. WHERE...All of Wisconsin WHEN...Until noon Monday, August 4 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 surface air quality. A mix of Unhealthy for Sensitive Groups (USG; Orange) AQI and Unhealthy (Red) AQI is forecast again today as smoke persists over the region and continues to recirculate around a slowly moving surface high pressure system. The heaviest smoke is expected across eastern Wisconsin today, while lighter impacts are more likely for western counties. A few locations may observe Moderate (Yellow) AQI, especially to the west. Conditions will continue to be reevaluated on a day-to-day basis, including updates to the forecast and any associated Air Quality Advisories.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
