It's going to be a hot time in the old town as another wave of heat and humidity arrives, bringing with it elevated levels of ozone and keeping the pollution at ground level with us. Thursday saw another Ozone Action and Air Quality Alert Day as issued by the state Department of Environmental Quality and the Southeast Michigan Council of Governments, with Rachel Kulik at the National Weather Service saying our summer is promising to be a hot one. Kulik says it's the high temperatures and a stagnant air mass that heats up the ground level ozone, keeping the pollution with us and making it uncomfortable for persons suffering from asthma and other respiratory ailments. A high pressure system is expected to hang around for the next several days and she says a cold front, wind, or rain would clear up the air, but we haven't had that for a while. Safety officials remind us to try to stay cool, drink plenty of water and avoid outside exertion. Fort Gratiot Township officials today will be opening the township building along Keewahdin as a cooling center from 8am to 4:30pm. Kimball Township often has a cooling area available too as do other local governmental units. The 90 plus temperatures expected also cause for a Heat Advisory as issued Thursday by the National Weather Service.
