.DAY ONE...Today and Tonight

thunderstorms over the northern mountains this evening. It will
be windy at times in the mountains and foothills.

Air Quality Alert

1010 AM MDT Sat Sep 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 Friday September 18 to 400 PM Saturday September 19

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 Saturday, September 19, 2020.  Smoke
transported from both in- state and out-of-state wildfires will
result in fine particulate concentrations reaching the Unhealthy
for Sensitive Groups to Unhealthy range on Friday and Saturday.
Fine particulate concentrations in the Unhealthy category will be
most likely for locations in and near Ft. Collins on Friday, with
fine particulate concentrations reaching the Unhealthy for
Sensitive Groups category for the rest of the Front Range region.
Although some improvement is expected with air quality on
Saturday, the threat for periodic increases in smoke will remain
possible depending on wildfire activity. For health
recommendations, please see the Front Range Air Quality Forecast
below. 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.
