Air Quality Alert

910 AM MDT Wed Oct 21 2020


The Colorado Department of Public Health and Environment has
issued the following...

WHAT...Action Day for Particulates.

WHERE...Douglas, Jefferson, Denver, western Arapahoe, western
Adams, Broomfield, Boulder, Larimer, and Weld Counties

WHEN...400 PM Tuesday October 20 to 400 PM Wednesday October 21

IMPACTS...Action Day for Particulates is now in effect for the
seven-county Denver-Boulder metropolitan area. Requests to limit
driving of non- ZEV vehicles (i.e., gas or diesel) are now in
effect until at least 4 PM Wednesday, October 21, 2020.  Moderate
to heavy smoke can be expected Tuesday afternoon and evening for
locations in Larimer and Boulder counties near the Cameron Peak,
Calwood, and Lefthand Canyon wildfires, along with locations below
the fires in the Front Range Urban Corridor from Ft. Collins
southward to Longmont, Boulder, and Denver. Smoke levels will
likely fluctuate for these areas Tuesday night through Wednesday
afternoon, but the threat for periods of heavy smoke is expected
to continue. CDPHE requests 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. For

HEALTH INFORMATION...If smoke is thick or becomes thick in your
neighborhood you may want to remain indoors. 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.
