The Texas Commission on Environmental Quality designated Thursday as another Ozone Action Day for the San Antonio area.
Some San Antonians could suffer from breathing problems if they spend too much time outside on Thursday.
The San Antonio Metropolitan Health District noted that this would be the city's tenth such day.
A statement from Metro Health explained that ozone pollution will be so high that people with asthma, emphysema, and bronchitis should stay indoors. Young children and older adults could be affected too.
There's just a lot of sun and very little breeze.
Metro Health asked residents to voluntarily take the following steps to help keep pollution levels from getting worse:
- Refueling cars and trucks after 6 p.m.
- Avoid using the drive-thru at restaurants. Go inside instead.
- Turning a vehicle off instead of idling.
- Setting thermostats two to three degrees higher from 2 p.m. to 7 p.m.; setting programmable thermostats to higher temperatures when no one is home. The optimum energy-saving temperature is 78 degrees.
- Carpooling or using public transportation.
- Combining errands to reduce trips.
