Requests to limit driving of non- ZEV vehicles (i.e., gas or diesel) are now in effect until at least 4 p.m. Wednesday, August 26, 2020. Due to wildfire smoke transported into the Front Range, Ozone and Fine Particulate concentrations may both reach the Unhealthy for Sensitive Groups category at times through at least Wednesday afternoon. The greatest air quality impacts will be in the Denver Metro area, and northward along the I-25 corridor to Longmont, Fort Collins, and Greeley, including areas west of I-25 within the lower foothills, especially in Larimer County due to smoke from the Cameron Peak wildfire. Elevated levels of ozone are also possible in areas to the south of Denver, into the Colorado Springs area on Tuesday.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.

This is especially true for those with heart disease, respiratory illnesses, the very young, and the elderly. Consider limiting outdoor activity when moderate to heavy smoke is present. Consider relocating temporarily if smoke is present indoors and is making you ill. If visibility is less than 5 miles in smoke in your neighborhood, smoke has reached levels that are unhealthy.
