SUNDAY...

The Colorado Department of Public Health and Environment has
issued the following...

WHAT...Ozone Action Day Alert.

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

WHEN...400 PM Saturday June 29 to 400 PM Sunday June 30

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. Sunday,
June 30, 2024.  While Ozone concentrations are expected to remain
in the Good to Moderate range on Saturday, warmer and more
stagnant conditions on Sunday will allow for more Ozone
development. Ozone is expected to reach the Unhealthy for
Sensitive Groups level on Sunday, especially in western portions
of the Front Range Region.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
