Colorado Smoke Outlook

To Top

Saturday, March 17, 2018, 2:40 PM MDT

The 3,300 acre Carson Midway wildfire is burning near the eastern edge of Fort Carson in southwestern El Paso County and northwestern Pueblo County. Smoke from this fire may be visible along I-25 in between Colorado Springs and Pueblo. Light smoke may be present in the immediate vicinity of the fire, however no hazards to public health are expected. Within the burn scar, many bales of tires are known to have burned, and may continue to produce localized areas of increased health risk if this smoke is encountered. Additional caution is advised for areas directly in the path of the smoke from the Carson Midway fire. At this time, no communities are known to be affected. Wind near the fire will be out of the south on Saturday afternoon. Smoke from this fire is expected to move to the north of the fire on Saturday afternoon, with winds shifting to come from the west Saturday evening. Smoke will be transported to the east of the fire overnight Saturday night and early Sunday morning.

The 28,213 acre Stateline wildfire is located approximately 20 miles to the southeast of Kim and 40 miles to the west of Campo in extreme southeastern Las Animas County. Smoke from this fire will be transported to the north of the fire during the day on Saturday and continuing overnight into Sunday morning. Smoke is not expected to create any health impacts to local communities.

Light to moderate smoke is also possible near prescribed fires and small wildfires 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. 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.
