The air qualityalert is in effect Tuesday, June 4 and Wednesday, June 5, 2024 from11 AM until 8 PM each day.Elevated levels of ozone - the predominant summertime pollutant -are likely to result in poor air quality in the afternoon and early-evening hours.

Children, older adults, and people with asthma or COPD maybe more sensitive to the health effects of ozone.Air quality can change depending on time of day and weatherconditions. Increased emissions of chemicals and faster ozoneformation rates due to heat, along with low winds and stagnantweather can cause unusually high and persistent levels of ozonepollution.To help minimize ozone air pollution levels:* Limit the use of gasoline powered lawn and garden equipment untilevening hours* Conserve electricity and set your air conditioner at a highertemperature* Try to delay trips to the gas station and the use of householdchemicals until the eveningCheck air quality levels and take appropriate action as needed.
