Air quality alert and dense fog advisory

An air quality alert and dense fog advisory have been issued for an area of Wisconsin that includes Kenosha County.

The air quality alert comes from the Wisconsin Department of Natural Resources and is due to stagnant conditions creating unhealthy conditions for people sensitive to fine particles in the air. The alert is in effect until 11 p.m., Friday. Says the DNR:

The advisory is being issued because of persistent elevated levels of fine particles in the air. These fine particles come primarily from combustion sources, such as power plants, factories and other industrial sources, vehicle exhaust, and wood burning. The Air Quality Index is currently in or expected to soon be in the orange level, which is considered unhealthy for people in sensitive groups. People in those sensitive groups include those with heart or lung disease, asthma, older adults and children. When an orange advisory for particle pollution is issued, people in those groups are advised to reschedule or cut back on strenuous activities. People with lung diseases such as asthma and bronchitis, and heart disease should pay attention to cardiac symptoms like chest pain and shortness of breath or respiratory symptoms like coughing, wheezing and discomfort when taking a breath, and consult with their physician if they have concerns or are experiencing symptoms. Fine particle pollution deposits itself deep into the lungs and cannot easily be exhaled. People who are at risk are particularly vulnerable after several days of high particle pollution exposure.

The National Weather Service has issued the dense fog advisory to last until 9 a.m., Saturday. During the advisory time visibility may be limited to a quarter mile or less. Due to temperatures overnight, some of the fog may freeze, which can lead to slick roadways. “Elevated surfaces will be most susceptible,” says the advisory.
