National Weather Service Issues Air Quality Alert in Texas, Advises Reduced Vehicle Use
The National Weather Service has issued an air quality alert for several regions in Texas, including Dallas-Fort Worth, Houston, Galveston, and Brazoria, due to expected elevated levels of ozone. Residents are advised to limit vehicle use on Memorial Day to help reduce ozone pollution. The alert encourages carpooling, walking, biking, and other measures to decrease emissions. Ozone Action Days have been declared, indicating that ozone levels may reach or exceed the Environmental Protection Agency's (EPA) Air Quality Index Level Orange threshold. This threshold is defined as an eight-hour average of 71 parts per billion or a one-hour average of 125 ppb. The Texas Commission on Environmental Quality (TCEQ) uses historical weather patterns, ozone monitoring data, and predictive models to issue these alerts, coordinating with the National Weather Service for dissemination.
