Today's Ozone Warnings
The ozone warning program was initiated in 2000 to issue warnings to the public based on measured levels of ozone in the atmosphere. The initial warning system specifically targeted high ozone levels in the Houston-Galveston-Brazoria, Dallas-Fort Worth, and San Antonio areas. The latest area to be added is the Austin area. Other metropolitan areas will be added in the future.
