WHEN...400 PM Sunday August 02 to 400 PM Monday August 03

IMPACTS...Ozone Action Day Alert is now in effect for the Front
Range Urban Corridor. Requests to limit driving of non-ZEV
vehicles (i.e., gas or diesel) are now in effect until at least 4
p.m. Monday, August 3, 2020.  Thunderstorms Sunday afternoon

Ozone concentrations in the Unhealthy for Sensitive Groups

areas included in this advisory that are not expected to reach the
Unhealthy for Sensitive Groups (USG) air quality designation, we
request that activities, such as driving non- ZEV vehicles (i.e.,

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