...OZONE ACTION DAY ALERT FROM 400 PM THURSDAY UNTIL 400 PM
FRIDAY...

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 Thursday July 18 to 400 PM Friday July 19

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,
July 19, 2024.  High levels of ozone are widespread throughout the
northern Front Range region on Thursday, with concentrations
possibly reaching the Unhealthy category in the southwestern
portions of the Denver Metro area, and Unhealthy for Sensitive
Groups in other areas. Ozone is again expected to be Unhealthy for
Sensitive Groups on Friday, though the highest concentrations may
be isolated to the Denver area. 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.
