WHERE...El Paso, Douglas, Jefferson, Denver, Arapahoe, Adams,
Broomfield, Boulder, Larimer, Weld Counties.
WHEN...7/23/2019 4:00:00 PM MDT to 7/24/2019 4:00:00 PM MDT
ADDITIONAL DETAILS...Ozone Action Day Alert is now in effect for
the Front Range Urban Corridor.  Requests to limit driving are now
in effect until at least 4 PM Wednesday, July 24, 2019.  Hot and
sunny weather will lead to concentrations of ozone in the Moderate
to Unhealthy for Sensitive Groups range on Tuesday and Wednesday.
On Tuesday, concentrations in the Unhealthy for Sensitive Groups
category are most likely for locations in the western portions of
the Colorado Front Range and the adjacent lower foothills. This
includes locations in the Denver Metro area, and areas northward
along the Front Range Urban Corridor through Boulder, Longmont,
and Fort Collins.   On Wednesday, this area will expand to include
the Colorado Springs area, in addition to the previously mentioned
locations. For areas included in this advisory that are not
expected to exceed the Unhealthy for Sensitive Groups (USG) air
quality designation, we request that activities, such as driving,
be reduced to lessen the impacts on neighboring air quality.
Additional air pollution in this region may directly diminish air
quality or contribute to precursors which may also adversely
affect air quality.  For Colorado air quality conditions,
