Eagle-Rio Blanco-Pitkin-Garfield-Mesa-Routt-
910 AM MDT Fri Aug 14 2020

...AIR QUALITY HEALTH ADVISORY FOR WILDFIRE SMOKE FROM 900 AM
FRIDAY UNTIL 900 AM SATURDAY...

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

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

WHERE...Routt, Eagle, Jackson, Grand, Summit, Clear Creek, Gilpin,
Pitkin, Lake, Park, 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, Aspen, Leadville, Fairplay, Grand Junction, Palisade, De
Beque, Parachute, Rifle, Glenwood Springs, Carbondale, and Meeker

WHEN...900 AM Friday August 14 to 900 AM Saturday August 15

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 this morning as atmospheric mixing increases, with the
slowest improvement occurring in valley locations. By this afternoon
the wind across the fires will be out of a west to northwest
direction. This will bring periods of moderate to heavy smoke for
areas to the east and southeast of both wildfires, possibly
including locations as far away as the Continental Divide. By late
this evening smoke will begin to drain into lower lying areas
surrounding both fires. This will bring longer duration, heavy smoke
through early Saturday morning to several drainages near the Pine
Gulch wildfire including into the De Beque and Grand Junction areas.
Meanwhile, heavy overnight smoke from the Grizzly Creek wildfire
will impact locations along Interstate 70 in central and eastern
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.
