The 34,161 acre 416 wildfire is located in northern La Plata County, approximately 10 miles north of Durango. Winds on Wednesday will come primarily from the west, carrying smoke to east of the fire. Smoke from this fire will be visible from Highway 550 between, and including, Durango and Hermosa as well as surrounding areas.

The 474 acre Upper Mailbox wildfire located in San Miguel County, approximately 5 miles northeast of Redvale. Smoke will be transported to the southeast of the fire throughout the day on Wednesday, likely affecting rural portions of San Miguel County in the Uncompahgre National Forrest. Smoke may be visible from highway 145 between Naturita and Norwood. No public health impacts are expected.

The 14,684 acre Trail Mountain wildfire is located in central Utah, approximately 145 miles west of Grand Junction, Colorado. Smoke from this fire is being transported to the southeast of the fire, and is causing hazy skies, but no major health impacts, in far western portions of Colorado.

The 20,357 acre Badger Creek wildfire is located in Albany County, Wyoming, just north of the Colorado State Line, approximately 38 miles southwest of Laramie. Winds on Wednesday will come from the north throughout the day, carrying smoke to the south, likely affecting rural parts of Albany County and possibly locations as far south as the Colorado State line. Thunderstorms are also possible on Wednesday, and may produce gusty erratic winds that can send smoke in any direction. No public health impacts are expected.

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. Fine particulates may reach the Unhealthy category where smoke is heavy. Consider limiting outdoor activity when moderate to heavy smoke is present. People with heart or lung disease, older adults, and children should avoid prolonged or heavy exertion; everyone else should reduce prolonged or heavy exertion. 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.

ACTION DAYS: An Action Day for fine particulate matter (particulates), carbon monoxide, ozone or other pollutants indicates that either current air quality is unhealthy or conditions are expected to worsen later in the day or on the next day. Action Days for air pollutants generally indicate that air quality will be in either the Unhealthy or Unhealthy-for-Sensitive-Groups categories according to the Air Quality Index. Action Days trigger voluntary pollution prevention measures, which may vary by season, and public health recommendations.

The AIR QUALITY INDEX reports the daily level of air pollution on an hourly basis. The index reports the highest level of either carbon monoxide, fine particulates or ozone depending on which pollutant has the greatest hourly concentration. Values greater than 100 for carbon monoxide, fine particulates and ozone indicate exceedances of the pollutant's state and federal standards. Air Quality Index values between 0-50 are good, 51-100 moderate, 101-150 unhealthy for sensitive groups, 151-200 unhealthy, 201-300 very unhealthy, and over 300 hazardous.
