What happened

Residents of the Houston, Galveston, and Brazoria areas have been asked by the Texas Commission on Environmental Quality (TCEQ) to avoid drive-thru lanes to reduce air pollution. The request is based on an alert from the National Weather Service, which warned that current weather conditions are conducive to producing high levels of ozone pollution. According to the US Environmental Protection Agency (EPA), such pollution can provoke breathing difficulties and lung inflammation. It is especially dangerous for children, the elderly, and people with chronic diseases like asthma. Houston is among the most ozone-polluted cities in the country and frequently faces ozone pollution challenges during warmer months. According to meteorologist Brandon Buckingham, warm and sunny days with light winds are more prone to ozone formation, helping the chemical reactions producing it. When air is stagnant, pollutants do not get dispersed, create ozone, and push it to unhealthy levels.
Weather forecasts for Wednesday (April 9) show ozone levels in the city area well above the values considered safe by the EPA. This triggered the alert and the request for voluntary pollution-reducing behaviors. These behaviors include avoiding idling in drive-thru lanes, biking, packing lunch to avoid mid-day driving, sharing a ride, and conserving electricity. They are all suggestions and not mandatory actions. TCEQ informs the public in advance about the critical situation and outlines simple actions that can help reduce the pollution contributing to ozone formation. The commission and the EPA will continue to monitor pollution levels and issue further guidance as needed.
