Stagnant conditions will allow for smoke from firework displays to accumulate in the metro Detroit area with improvement Saturday afternoon. For Ozone, however, conditions will be primed for potential USG concentrations Saturday afternoon. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with heart disease and respiratory diseases like asthma. Monitor for symptoms such as wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes. Reduce or eliminate activities that contribute to air pollution, such as: outdoor burning, use of residential wood burning devices. Avoid activities which can lead to ozone formation. These activities include: refueling vehicles or topping off when refueling, using gasoline powered lawn equipment, using charcoal lighter fluid.
