City on Alert: San Antonio Braces for Ozone Action Day

In an abrupt weather warn, San Antonio’s officials have raised an Ozone Action Day alert for the city on September 30, 2024. The City of San Antonio announced the alert following warnings of favorable atmospheric conditions predicted to lead to high levels of ozone air pollution, potentially exacerbating respiratory problems among certain groups in the community.

Seventh Ozone Action Day of 2024

The Texas Commission on Environmental Quality informed the city about its seventh Ozone Action Day of this year on Sunday, September 29, as per a city news release.

For these populations, exposure to elevated ozone levels can significantly result in respiratory distress.

Recommendations to Mitigate Risk

Actions for Improving Air Quality

The city has also proposed several actions for community members to follow to maintain the city’s air quality healthy. These include:

• Refueling vehicles after 6 p.m.
• Avoiding drive-thru at eateries and opting to go inside.
• Turning off vehicles instead of letting them idle.
