COLORADO SMOKE OUTLOOK:
Friday, July 31, 2015, 2:25 PM

Light to moderate smoke is possible near prescribed fires and small wildfires around the state.

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.
