810 PM MDT Wed Oct 21 2020

...ACTION DAY FOR PARTICULATES FROM 400 PM WEDNESDAY UNTIL 400 PM
THURSDAY...

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 Wednesday October 21 to 400 PM Thursday October 22

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 Thursday, October 22, 2020.  Areas of
heavy smoke can be expected Wednesday evening for locations in
Larimer and Boulder counties near the Cameron Peak, Calwood, and
Lefthand Canyon wildfires and downwind from the East Troublesome
wildfire, including Estes Park. CDPHE recommends residents in
these areas remain indoors through early Friday morning.
Locations below the wildfires in the Front Range Urban Corridor
from Ft. Collins southward to Longmont, Boulder, and possibly
Denver could also receive heavy smoke at times. Smoke levels will
likely fluctuate for these areas through Thursday, but the threat
for periods of heavy smoke will 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 Colorado air quality
conditions, forecasts and advisories, visit:

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.
