910 AM MDT Wed Aug 12 2020

...ACTION DAY FOR MULTIPLE POLLUTANTS FROM 400 PM TUESDAY UNTIL
400 PM WEDNESDAY...

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 Tuesday August 11 to 400 PM Wednesday August 12

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. Wednesday, August 12, 2020.  Due to the influence of
wildfire smoke transported into the Front Range, Ozone and Fine
Particulate concentrations could both reach the Unhealthy for
Sensitive Groups category at times through Wednesday afternoon
across the northern Colorado Front Range region. The greatest air
quality impacts are expected to be in locations within the Denver
Metro area, as well as northward along the I-25 corridor to
Longmont, including areas west of I-25 within the lower
foothills.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. For
Colorado air quality conditions, forecasts and advisories, visit:
https://www.colorado.gov/airquality/colorado_summary.aspx

HEALTH INFORMATION...Increasing likelihood of respiratory symptoms
in sensitive individuals, aggravation of heart or lung disease and
premature mortality in people with cardiopulmonary disease and
older adults. People with heart or lung disease, older adults, and
children should reduce prolonged or heavy exertion.

...AIR QUALITY HEALTH ADVISORY FOR WILDFIRE SMOKE FROM 900 AM
WEDNESDAY UNTIL 900 AM THURSDAY...

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

WHAT...Air Quality Health Advisory for Wildfire Smoke.

WHERE...Issued for Routt, Eagle, Jackson, Grand, Summit, Clear
Creek, Gilpin, northern Mesa, central and eastern Garfield, and
eastern Rio Blanco Counties. Locations include, but are not
limited to Steamboat Springs, Oak Creek, Hayden, Breckenridge,
Silverthorne, Eagle, Avon, Vail, Walden, Kremmling, Granby,
Georgetown, Central City, Grand Junction, Palisade, De Beque,
Parachute, Rifle, Glenwood Springs, and Meeker.

WHEN...900 AM Wednesday August 12 to 900 AM Thursday August 13

IMPACTS...Widespread heavy smoke has been observed across large
sections of northern, central, and western Colorado due to the
Pine Gulch and Grizzly Creek wildfires. Smoke will gradually
diminish Wednesday morning as atmospheric mixing increases, with
the slowest improvement occurring in valley locations. By
Wednesday afternoon the wind at the fires will be out of a west to
southwest direction. This will bring periods of moderate to heavy
smoke for areas to the east and northeast of both wildfires,
including locations as far away as the Continental Divide. By late
Wednesday evening smoke will begin to drain into lower lying areas
surrounding both fires. This will bring longer duration, heavy
smoke through early Wednesday morning to several drainages near
the Pine Gulch wildfire including Hunter Canyon, Corcoran Wash,
South Dry Fork, Middle Dry Fork, North Dry Fork, Dry Fork Roan
Creek, Roan Creek, Kimball Creek, and into the Grand Junction
area. Meanwhile, heavy overnight smoke from the Grizzly Creek
wildfire will impact locations along Interstate 70 in central and
eastern parts of Garfield County.

HEALTH INFORMATION...Public Health Recommendations: 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.
