Colorado Smoke Outlook

COLORADO SMOKE OUTLOOK:
Sunday, September 20, 2020, 2:00 PM MDT

Wildfire smoke is expected to increase across the Front Range region Sunday night into Monday morning due to significant fire activity at the Cameron Peak and Mullen wildfires. Smoke will initially increase in areas such as Ft. Collins and Greeley Sunday evening before spreading southward into the Denver metro area by early Monday morning. An Action Day for Fine Particulates has been issued for these areas.

Elsewhere in Colorado, occasional smoke from both in-state and out-of-state wildfires will continue to move through the state Sunday and Monday. Hazy skies and moderate concentrations of smoke will be most likely for northern and western parts of Colorado. Therefore, we suggest that unusually sensitive people reduce prolonged or heavy exertion in all parts of northern and western Colorado through at least Monday afternoon.


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.
