Ozone season begins

The 2021 ozone season began March 1, signaling the resumption of daily air quality forecasts across North Carolina. 

Through Oct. 31, these county-based forecasts from the N.C. Division of Air Quality will include statewide ozone forecasts as well as year-round forecasts for fine particle pollution. Ozone forms in the air when nitrogen oxides react with hydrocarbons on warm, sunny days with little wind. 

Next-day and extended products are issued by 3 p.m. with a morning update by 10 a.m. Find it at https://bit.ly/3ssiwcd.

We don’t plan to change that model. Support from our readers will help us maintain and strengthen the editorial independence that is crucial to our mission to help make Western North Carolina a better place to call home. If you are able, please support The Smoky Mountain News.
