Air Quality Alert
Issued: 3:14 PM Aug. 15, 2020 – National Weather Service
...ACTION DAY FOR MULTIPLE POLLUTANTS FROM 400 PM FRIDAY UNTIL 400 PM SATURDAY... The Colorado Department of Public Health and Environment has issued the following... WHAT...Action Day for Multiple Pollutants. WHERE...Douglas, Jefferson, Denver, western Arapahoe, western Adams, Broomfield, Boulder, Larimer, and Weld Counties WHEN...400 PM Friday August 14 to 400 PM Saturday August 15 IMPACTS...Action Day for Multiple Pollutants 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. Saturday, August 15, 2020. Due to wildfire smoke transported into the Front Range, Ozone and Fine Particulate concentrations could both reach the Unhealthy for Sensitive Groups category at times through Saturday afternoon across the Colorado Front Range region. The greatest air quality impacts are expected to be for locations within the Denver Metro area, as well as northward along the I-25 corridor to Fort Collins, including areas west of I-25 within the foothills, especially in Larimer County due to smoke from the Cameron Peak wildfire. 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.
