Friday, October 18, 2019, 9:20 AM MDT

Air Quality Health Advisory for Wildfire Smoke

Issued for portions of central and southern Colorado
Issued at 8:00 AM MDT, Friday, October 18, 2019

Issued by the Colorado Department of Public Health and Environment

Affected Area: southeastern Chaffee and northwestern Fremont Counties, including, but not limited to the communities of Wellsville, Howard, Coaldale, and Cotopaxi.

Advisory in Effect: 8:00 AM MDT, Friday, October 18, 2019 to 9:00 AM MDT, Saturday, October 19, 2019.

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.

Outlook: Periods of moderate to heavy smoke are expected from the Decker wildfire, located in the Sangre de Cristo Wilderness, approximately 2 miles south of Salida. Winds will be mainly out of the west on Friday, transporting smoke to locations east of the fire. Winds may become breezy to gusty by Friday afternoon, potentially increasing fire activity and smoke production. Increased relative humidity and possible precipitation may decrease fire activity, however the threat from residual smoke production remains in this area. Overnight Friday night the winds will turn somewhat lighter, but may remain breezy at times. Smoke impacts will continue to be felt for areas immediately east of the fire, possibly bringing periods of moderate to heavy smoke to Wellsville, Howard, Coaldale, and Cotopaxi through Saturday morning.

Affected Area: eastern Ouray and southern Gunnison Counties.

Advisory in Effect: 8:00 AM MDT, Friday, October 18, 2019 to 9:00 AM MDT, Saturday, October 19, 2019.

Public Health Recommendations: If smoke is thick or becomes thick in your neighborhood you may want to remain indoors.

Outlook: Periods of moderate to heavy smoke are expected from the Cow Creek wildfire, located in eastern Ouray County approximately 9 miles southeast of Ridgeway. Winds will generally be out of the west or northwest during the day on Friday, transporting smoke to areas east or southeast of the fire. Daytime smoke impacts will generally be limited to the Uncompaghre National Forest in eastern Ouray and southern Gunnison counties. Overnight Friday night and into Saturday morning, winds out of the south or southwest will persist at the fire, though winds will be light to breezy overnight. This may continue to push smoke into the Uncompahgre National Forest. The likelihood of rain and snow showers increases on Friday, and could decrease smoke production, however breezy winds and residual smoke production will keep smoke impacts possible in the immediate vicinity of the fire.


Air Quality Health Advisory for Wildfire Smoke

Issued for a small portion of southwestern Colorado
Issued at 8:00 AM MDT, Friday, October 18, 2019

Issued by the Colorado Department of Public Health and Environment

Affected Area: western Archuleta County, including, but not limited to the community of Piedra.

Advisory in Effect: 9:00 AM MDT, Friday, October 18, 2019 to 9:00 AM MDT, Saturday, October 19, 2019.

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.

Outlook: Very dry conditions with occasionally gusty winds have increased smoke production from a prescribed burn that was completed several weeks ago. Areas of moderate to heavy smoke are currently impacting just a small portion of western Archuleta County. The main area impacted includes locations along State Highway 160 to the east of Yellowjacket Pass, eastward to the town of Piedra. Periodic smoke is expected to continue through at least early Saturday morning.


The 622 acre Elk wildfire is located in central Larimer County, approximately 6 miles southeast of the Red Feather Lakes area. The winds near the fire on Friday will mainly be out of the northwest, transporting smoke to areas of central Larimer County southeast of the fire. Winds may be breezy to gusty on Friday and may increase smoke production from this fire. Increased relative humidity and chances for precipitation will help to limit fire activity, however lingering impacts from residual smoke production remain present in this area. The main smoke impacts from this fire are expected to be to the south of Red Feather Lakes Road, north of Poudre Canyon Road, and west of Greyrock Mountain. Although the most significant impacts from smoke are expected to remain in largely rural portions of Larimer County, lesser smoke impacts may be present in areas further downwind of the fire, including, but not limited to, Poudre Park, La Porte, Wellington, Fort Collins, and Loveland. In areas where Moderate smoke impacts are experienced unusually sensitive people should consider reducing heavy or prolonged exertion.

The 1,069 acre Middle Mamm wildfire is located in southern Garfield County, near the Garfield/Mesa County line, approximately 10 miles south of Rifle. Winds near the fire on Friday will be mainly out of the west or northwest, transporting smoke to areas to east or southeast of the fire. Winds may be gusty at times on Friday afternoon, potentially increasing fire activity and smoke production. Increased relative humidity and chances for precipitation will help to limit fire activity, however lingering impacts from residual smoke production remain present in this area. Daytime health impacts from smoke are expected to be minimal, but smoke may be visible in surrounding areas including on Interstate 70 near Rifle. During the overnight hours into early Saturday morning, expect smoke to drain along low lying areas near the immediate vicinity of the fire.

The 720 acre Granite Lake Fire is located in eastern Pitkin County, approximately 12 miles east of Aspen. Winds near the fire on Friday will mainly come out of the west or northwest, moving smoke to locations east or southeast of the fire. Smoke may be visible at times in Aspen, Leadville and Twin Lakes. Winds may be gusty at times on Friday afternoon, potentially increasing fire activity and smoke production. Increased relative humidity and chances for precipitation will help to limit fire activity, however lingering impacts from residual smoke production remain present in this area. Overnight Friday into the early morning hours on Saturday, lingering smoke will continue to move east of the fire and settling in low lying areas in the vicinity of the fire.

Light to moderate concentrations of smoke are also possible near additional small wildfires and prescribed burns around the state.

What if there is a wildfire or smoke in your area?
The focus of the Colorado Smoke Outlook is on large fires (e.g., greater than 100 acres in size). Nevertheless, smoke from smaller fires, prescribed fires, and/or smoke from new fires not yet known to CDPHE air quality meteorologists may cause locally heavy smoke. If there is smoke in your neighborhood, see the public health recommendations below.

Public health recommendations for areas affected by smoke:
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.
