Smoke from Canadian wildfires may cause haze in Minnesota
Air pollution monitors across Minnesota are measuring elevated levels of fine particle pollution this week. Satellite imagery indicates that the elevated fine particle levels are likely the result of transported Canadian wildfire smoke, which is blanketing much of Minnesota.
The Minnesota Pollution Control Agency (MPCA) is not issuing an air 07-12-13 quality advisory at this time; today’s air quality forecast for the Twin Cities and Rochester is 87 AQI, which is considered moderate air quality. However, even moderate air quality may cause health effects in individuals who are very sensitive to air pollution. Hazy skies are expected to persist throughout the day today and there may be isolated areas of dense smoke.
Winds are expected to shift to southerly, and these winds may transport additional wildfire smoke into Minnesota from fires in the Central Plains. Air pollution levels are expected to remain elevated through Friday, July 12.
The Grand Portage “Haze Cam,” which measures air quality in Grand Portage recorded a moderate amount of haze in the Arrowhead. Up to the minute air quality information can be seen on-line at: http://www.mwhazecam.net/site.aspx?site=grand
When air pollution levels are high, the MPCA recommends that persons in areas where the smell of smoke or visible haze is present take precautions to reduce exposure. When smoke is present, individuals are encouraged to remain indoors and reduce activity levels. Those with pre-existing cardiovascular or respiratory problems, such as asthma, are particularly susceptible to increases in air pollution as are the elderly and children.
