Welcome to the JAC Ozone Action Day Page. I'm OZAD, your host.
Ozone Action Days are usually called when ground-level ozone is predicted to approach unhealthful levels and the National ozone standard could be exceeded. TCEQ forecasters and meteorologists are on alert during the ozone season between May 1 - October 31, looking at air quality condition across the state. Each forecast is a simple yes or no prediction for the question, "Will ozone levels reach or exceed a target level for a particular area?"
What conditions are "just right" for ozone formation??
What is an Ozone Advisory??
Local television and radio stations alert the public to an ozone action day prediction. On such days, the community can take simple, voluntary actions to help reduce the risk of ground-level ozone. Some symptoms of breathing ground level ozone are chest pain, coughing, nausea, throat irritation, and congestion. It may also aggravate bronchitis, heart disease, emphysema, and asthma. Children, senior citizens, and those with asthma or other respiratory problems are urged to limit outdoor activities when an ozone action day is predicted.
