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

Fine Particulate Matter concentrations are expected to be in the Good to Moderate range on Tuesday and Wednesday. Moderate concentrations are most likely in northern portions of the Front Range, including the Denver metro area, Boulder, Longmont, Greeley, and surrounding areas. In these areas unusually sensitive people should consider reducing prolonged or heavy exertion on Tuesday and Wednesday.

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

Nitrogen Dioxide concentrations are expected to be in the Good category on Tuesday, and in the Good to Moderate range on Wednesday. Moderate concentrations of nitrogen dioxide are most likely for locations near busy roadways within the Denver Metro area during peak traffic periods. For health recommendations, please see Fine Particulate Matter above.

COLORADO SMOKE OUTLOOK:
Tuesday, January 31, 2023, 2:15 PM MST

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. To temporarily relocate to an area with better air quality, consider using this map (https://fire.airnow.gov/) to identify the best area closest to you. IF VISIBILITY IS LESS THAN 5 MILES IN SMOKE IN YOUR NEIGHBORHOOD, SMOKE HAS REACHED LEVELS THAT ARE UNHEALTHY.
