COLORADO SMOKE OUTLOOK:
Sunday, July 24, 2016, 2:00 PM MDT

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, Sunday, July 24, 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, Sunday, July 24, 2016 to 9:00 AM MDT, Monday, July 25, 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 remain at unhealthy levels in Cotopaxi Sunday morning. Similar smoke concentrations are likely in Coaldale. The wind will generally be light and variable in direction near the fire on Sunday, however scattered afternoon and evening thunderstorms are also expected. These thunderstorms could produce erratic, gusty winds and send smoke in any direction. Light winds are expected late Sunday night and Monday 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.


SMOKE FROM OTHER WILDFIRES:
The 25,491 acre Beaver Creek Wildfire is located in northwestern Jackson County approximately 24 miles northwest of Walden. Increasing westerly winds are expected at the fire on Sunday which would tend to send smoke to locations east of the fire. Light winds are expected at the fire late Sunday night and drainage flow will likely pool smoke, perhaps heavy at times, to northern parts of North Park into Monday morning. This would mainly include the area to the north of the community of Cowdrey to the Wyoming state line.

What if there is a wildfire or smoke in your area that is not reported above?

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.
