The National Weather Service (NWS) Chicago has issued a special weather statement due to smoke from a Minnesota forest fire. According to NWS, the smoke traveled more than 400 miles due to a combination of sinking air and northerly winds.
NWS warns the smoke will persist through the afternoon and into the evening hours. The Lake County Illinois Emergency Manager reports that smoke is prevalent enough to cause people to experience difficulty breathing and burning eyes. People with respiratory problems should use caution.
