Air Quality Alert

510 PM MDT Mon Oct 19 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 Monday October 19 to 400 PM Tuesday October 20

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 Tuesday, October 20, 2020.  Moderate to
heavy smoke can be expected through Tuesday morning for locations
in Larimer and Boulder counties near the Cameron Peak, Calwood,
and Lefthand Canyon wildfires. Lesser, but moderate, amounts of
smoke can be found below these fires along the Front Range Urban
Corridor, particularly from Ft. Collins southward to Loveland,
Longmont, and Boulder. However drier and windier weather during
the day on Tuesday could increase fire activity, so an increase in
smoke will be possible by Tuesday afternoon for larger sections of
the Front Range from Ft. Collins southward to Denver. 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.

This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Gusty winds and continued dry conditions will result in high fire
danger across Colorado through the evening hours where many areas
will experience wind gusts over 30 mph. Expect another breezy
night across the higher Front Range foothills with wind gusts to
50 mph possible. A Red Flag Warning is in effect for central and
southeast Park County.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

This week will be dry with windy conditions in the higher
mountains. As a result, fire danger will generally remain high
but not extreme. There may be a bit of an increase in wind and
fire danger Wednesday and early Thursday ahead of a cold front.
The plains will generally have lighter winds and more moisture,
though it could be breezy at times. The cold front will bring
light snow to the higher mountains Thursday and Thursday night,
with a slight chance of snow on the plains. There will be a better
chance of snow with additional cooling about Sunday.


Spotter activation will not be needed today and tonight.
