Front Range Air Quality Forecast & Colorado Smoke Outlook

FRONT RANGE AIR QUALITY FORECAST:
Monday, November 20, 2017, 2:15 PM MST

Ozone concentrations are expected to be in the Good category on Monday and Tuesday.

Fine Particulate Matter concentrations are expected to be in the Good to Moderate range on Monday and Tuesday. Moderate concentrations of fine particulates are most likely for locations within the Denver Metro area, particularly near heavy industrial areas. Unusually sensitive people should consider reducing prolonged or heavy exertion in these areas on Monday and Tuesday.

Carbon Monoxide concentrations are expected to be in the Good category on Monday and Tuesday.

Nitrogen Dioxide concentrations are expected to be in the Good category for the remainder of Monday, and in the Good to Moderate range on Tuesday. Moderate concentrations of nitrogen dioxide are most likely in the Denver Metro area near busy roadways, particularly between the hours of 6-10 AM. In these areas unusually sensitive people should consider reducing prolonged or heavy exertion on Tuesday.

Visibility is expected to be Good to Moderate on Tuesday.

COLORADO SMOKE OUTLOOK:
Monday, November 20, 2017, 2:20 PM MST

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?

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.
