WHAT...Ozone Action Day Alert.

WHERE...Douglas, Jefferson, Denver, western Arapahoe, western
Adams, Broomfield, Boulder, Larimer, and Weld Counties

WHEN...400 PM Thursday August 15 to 400 PM Friday August 16

IMPACTS...Ozone Action Day Alert is now in effect for the Front
Range Urban Corridor. Request to limit driving gas and diesel-
powered vehicles is now in effect until at least 4 p.m. Friday,
August 16, 2024. Afternoon showers will limit ozone development on
Thursday, and concentrations are expected to be in the Good to
Moderate range. However, hot, dry and stagnant weather will allow
Ozone to reach the Unhealthy for Sensitive Groups Category on
Friday.For areas included in this advisory that are not expected
to reach the Unhealthy for Sensitive Groups (USG) air quality
designation, we request that activities, such as driving non-ZEV
vehicles (i.e., gas or diesel), be reduced to lessen the impacts
on neighboring air quality. Additional air pollution in this
region may directly worsen air quality or contribute to precursors
which may also adversely affect air quality. For Colorado air
quality conditions, forecasts and advisories, visit:

HEALTH INFORMATION...Increasing likelihood of respiratory symptoms
and breathing discomfort in active children and adults and people
with lung disease, such as asthma. Active children and adults, and
people with lung disease, such as asthma, should reduce prolonged
or heavy outdoor exertion.

to Fort Collins.For areas included in this advisory that are not
expected to reach the Unhealthy for Sensitive Groups (USG) air
quality designation, we request that activities, such as driving
non-ZEV vehicles (i.e., gas or diesel), be reduced to lessen the

category on both Monday and Tuesday during the afternoon and
evening hours. Note: southeastern Larimer County, including
Loveland, will also be impacted by possibly heavy wildfire smoke
from the Alexander wildfire through at least Tuesday morning.
