This is the Front Range Air Pollution Forecast effective 4PM on Friday, June 28, 2024:
No Advisories for Ozone or any other pollutant are in effect until at least 4 p.m. Saturday, June 29, 2024 for the Front Range Urban Corridor from Douglas County north to Larimer and Weld counties, including the Denver-Boulder area, Fort Collins and Greeley.
Mild temperatures and favorable winds are expected to keep ozone levels in the Good to Moderate range through at least Saturday afternoon.
Should atmospheric conditions suggest increased ground-level ozone concentrations, the Colorado Department of Public Health and Environment and the Regional Air Quality Council will issue an ozone advisory. In addition, if conditions warrant, the Colorado Department of Public Health and Environment will issue advisories for other pollutants. Check this website (https://colorado.gov/airquality/advisory.aspx) often for a report on current air quality conditions and to learn if an ozone action day alert is in effect.

| FRONT RANGE AIR QUALITY FORECAST: Friday, June 28, 2024, 1:45 PM MDT Ozone concentrations are expected to be in the Good to Moderate range on Friday and Saturday. Unusually sensitive people should consider reducing prolonged or heavy outdoor exertion between noon and 8 pm on Friday and Saturday. Fine Particulate Matter concentrations are expected to be in the Good category on Friday and Saturday. Carbon Monoxide concentrations are expected to be in the Good category on Friday and Saturday. Nitrogen Dioxide concentrations are expected to be in the Good category on Friday and Saturday. Visibility on Saturday is expected to be Good to Moderate. COLORADO SMOKE OUTLOOK: Friday, June 28, 2024, 1:50 PM MDT The 1,071 acre Oak Ridge Fire is burning near the Pueblo/Custer County line, approximately 3 miles northwest of Beulah. Smoke impacts have remained light in areas near the fire. Increased cloud cover and relative humidity are expected to temper fire behavior and limit smoke production. Thunderstorms remain possible during the afternoon hours, which can produce gusty, erratic winds that could send smoke in any direction. Primary smoke impacts during the daytime hours are expected to remain highly localized to areas in the immediate vicinity of the fire, with little public health impacts anticipated. As the winds decrease during the late evening and overnight hours, smoke will settle in low lying terrain in areas below the fire, and light to moderate smoke is possible in Beulah. The Air Quality Health Advisory for Wildfire Smoke has been allowed to expire, however CDPHE/APCD will monitor conditions closely and will re-issue the advisory if conditions worsen. Individuals who are unusually sensitive to smoke should consider reducing prolonged or heavy exertion in areas where smoke is apparent. Light to moderate concentrations of smoke are also 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. |

Ground-level ozone is an air pollution problem that impacts the health of all Coloradans. Exposure can cause acute respiratory problems and trigger asthma attacks. During Ozone Action Alerts, avoid rigorous outdoor activity during the heat of the day. Prolonged exposure can cause long-lasting damage to your lungs.
You CAN make a difference by doing your part to improve air quality along Denver's Front Range. Even during periods of wildfire smoke, reducing your personal emissions can help decrease ozone production. Combining or skipping just two car trips a week has a positive impact on our air quality.

WHAT IS AN ACTION DAY?: An Action Day for fine particulate matter, carbon monoxide, ozone or other pollutants indicates that either current air quality is unhealthy or conditions are expected to worsen later in the day or on the next day. Action Days for air pollutants generally indicate that air quality will be in either the Unhealthy or Unhealthy-for-Sensitive-Groups categories according to the Air Quality Index. Action Days always convey overarching public health recommendations, and, according to season, trigger a variety of mandatory and voluntary pollution prevention measures. For example, during the summer open burning is prohibited when an Action Day for ozone and/or fine particulates is in effect. During the winter, residential burning restrictions are in effect when an Action Day for Visibility is in effect.
