Colorado Smoke Outlook

Thursday, October 29, 2020, 2:00 PM MDT

Areas of moderate to locally heavy smoke will be possible for areas surrounding the East Troublesome wildfire in Grand and southwestern Larimer counties. Smoke will be most likely for locations immediately to the south and east of the fire, including Grand Lake, Granby, Hot Sulphur Springs, Parshall, and Estes Park. In these areas, unusually sensitive people should consider reducing prolonged or heavy exertion, especially during the morning hours when smoke is expected to be at it's heaviest.

Light to moderate concentrations of smoke are possible near small wildfires and prescribed burns 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. 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.
