COLORADO SMOKE OUTLOOK:
Tuesday, July 7, 2015, 2:25 PM

WILDFIRE SMOKE HEALTH ADVISORY
Issued for all of Colorado to the east of the Continental Divide
Issued at 3:00 PM MDT, Tuesday, July 7, 2015
Affected Area: all of Colorado to the east of the Continental Divide, including the entire northern and southern Front Range region. Cities include, but are not limited to Denver, Boulder, Ft. Collins, Greeley, Colorado Springs, Pueblo, Trinidad, Lamar, Burlington and Sterling.
Advisory in Effect: 3:00 PM MDT Tuesday 07/07/15 to 9:00 AM MDT Wednesday 07/08/15

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.

Outlook: Light to locally heavy smoke transported from large wildfires in Canada will continue to impact all of Colorado to the east of the Continental Divide. Despite some improvement in conditions Tuesday afternoon, unhealthy levels of smoke will continue at times over the advisory area through Wednesday morning.

Light to moderate smoke is also possible near prescribed fires and small wildfires elsewhere 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.
