Request to limit driving gas and diesel- powered vehicles is now in effect until at least 4 p.m. Thursday, June 13, 2024. Although ozone is expected to remain in the Moderate category on Wednesday due to gusty westerly winds developing, higher ozone is anticipated for Thursday. The highest ozone concentrations on Thursday are most likely for southwestern parts of the Denver metro area, northward along the foothills to around Golden. For 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., gas or diesel), be reduced to lessen the impacts on neighboring air quality. Additional air pollution in this region may directly worsen air quality or contribute to precursors which may also adversely affect air quality.
