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

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

WHERE...Grand County. Locations include, but are not limited to
Grand Lake, Granby, Hot Sulphur Springs, and Parshall.

WHEN...900 AM Wednesday October 21 to 900 AM Thursday October 22

IMPACTS...Moderate to heavy smoke has been observed Wednesday
morning near the East Troublesome wildfire in northern Grand
County, including locations south of the fire along US Highway 40
in Granby, Hot Sulphur Springs, and Parshall. Smoke will gradually
decrease late Wednesday morning for these areas, however gusty
west to southwesterly winds Wednesday afternoon will create active
fire behavior and produce additional smoke. The wind will send
this smoke to areas east and northeast of the fire, possibly
impacting Grand Lake with periods of moderate to heavy smoke. The
wind will stay mainly out of the southwest Wednesday night,
continuing smoke impacts through early Thursday morning to lower
lying areas east and northeast of the fire, including State
Highway 125 to the north of Granby.

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.
