COLORADO SMOKE OUTLOOK:
Monday, June 14, 2021, 7:35 AM MDT

Areas of light to moderate smoke are possible across the portions of Delta, Mesa, and Garfield Counties, particularly in valley locations. Smoke will gradually decrease throughout the late morning hours, however any increase in fire activity at the Pack Creek wildfire in eastern Utah may increase smoke in these areas, particularly during late evening and overnight hours.

In these areas, as well as in other parts of Colorado not mentioned above, hazy skies and generally light to moderate concentrations of smoke are possible from wildfires in Arizona, New Mexico, and Utah. Across Colorado, particularly for locations on the Western Slope, interior mountain valley locations, and busier metropolitan areas, unusually sensitive people should consider reducing prolonged or heavy exertion on Monday.

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.

Additional Information

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.
