Requests to limit driving of non- ZEV vehicles (i.e., gas or diesel) are now in effect until at least 4 PM Wednesday, September 23, 2020. Wildfire smoke from the Middle Fork, Mullen, and Cameron Peak wildfires is expected to increase across northern parts of the Front Range region early Wednesday. Fine particulate concentrations in the Unhealthy for Sensitive Groups category will be most likely for Larimer and Weld Counties, including Ft. Collins and Greeley, but could spread southwards towards Denver later Wednesday morning into Wednesday afternoon. For health recommendations, please refer to the Front Range Air Quality Forecast below. For areas included in this advisory that are not expected to exceed 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.
