The Texas Commission on Environmental Quality has issued an Ozone Action Day for Austin and San Antonio metro areas for Wednesday.
Action days are declared when the Air Quality Index (AQI) gets to the level where the air is unhealthy for sensitive groups, and higher levels of ozone are possible. “Ozone mainly forms in the highest concentrations on warm, sunny days with light wind speeds, which allows more of the pollutant to form and accumulate,” TCEQ said.
Active children and adults, along with those with lung disease and asthma, are advised to reduce prolonged or heavy exertion outdoors. People can help prevent ozone pollution by sharing a ride, walking or riding a bicycle, avoiding drive through lanes, conserving energy and keeping vehicles properly tuned.
TCEQ also declared Dallas-Fort Worth and Houston areas to have Ozone Action Days on Wednesday.
