WHEN...400 PM Saturday June 22 to 400 PM Sunday June 23

IMPACTS...Ozone Action Day Alert is now in effect for the Front

of concern on Saturday and Sunday. Ozone concentrations in the
Unhealthy for Sensitive Groups category are most likely for
locations in and near the Denver Metro area, particularly in

worsen air quality or contribute to precursors which may also
adversely affect air quality.  For Colorado air quality
