Air Quality Health Advisory for Wildfire Smoke
Issued for Hayden Pass Wildfire in Fremont County approximately 5 miles southwest of Coaldale.
Issued at 9:00 AM MDT, Wednesday, July 27, 2016
Issued by the Colorado Department of Public Health and Environment
Affected Area: western parts of Fremont County. Locations include, but are not limited to Cotopaxi, Coaldale, Hillside, Howard and Texas Creek.
Advisory in Effect: 9:00 AM MDT, Wednesday, July 27, 2016 to 9:00 AM MDT, Thursday, July 28, 2016>
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: Smoke concentrations have improved in Cotopaxi Wednesday morning near the Hayden Pass fire. However, those concentrations remain high enough to continue the advisory at the present time. The wind near the fire today will generally be out of a north to northwest direction, which could send some light to moderate smoke southward into the San Luis Valley along with locations southeast of the fire, including Westcliffe. Light winds are expected late Wednesday night and Thursday morning. This will allow smoke to drain towards the Arkansas River, once again impacting Coaldale and Cotopaxi with periods of moderate to possibly heavy smoke. Lighter smoke will be possible in locations such as Howard, Texas Creek and possibly into northern parts of Custer County as far south as Westcliffe.
COLORADO SMOKE OUTLOOK:
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.
