Unusually warm temperatures, sunny skies and high levels of ozone coming in from the south and central United States are creating unhealthy air quality for some people in the metro and southern Minnesota.

The Minnesota Pollution Control Agency released an air quality alert Thursday that’ll be in effect from noon to 8 p.m. Friday. Air quality index levels are expected to climb through the afternoon and settle after sunset. People with respiratory problems, chronic obstructive pulmonary disease and heart conditions could be affected by the higher levels of ozone.

Those who have asthma or COPD, make sure to have your inhaler with you and take other necessary precautions, the MPCA said in the statement.

People of all ages who are doing extended or heavy, physical activity like playing sports or working outdoors may experience adverse health effects as well, including: difficulty breathing deeply, shortness of breath, throat soreness, wheezing, coughing or fatigue.

To curb the production of ozone, commuters are encouraged to carpool and fill up their tanks at dusk or dawn, avoid backyard fires and postpone using gas-powered lawn and garden equipment.

HEALTH PRECAUTIONS FOR AIR QUALITY ALERTS

Everyone should take precautions when the air quality is unhealthy, according to the MPCA.
