Boulder-Weld-Adams-Denver-Jefferson-Douglas-Arapahoe-
Broomfield-Larimer-
1010 PM MDT Wed Jul 28 2021

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

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 Wednesday July 28 to 400 PM Thursday July 29

IMPACTS...Ozone Action Day Alert is now in effect for the Front
Range Urban Corridor. Requests to limit driving of non-ZEV
vehicles (i.e., gas or diesel) are now in effect until at least 4
p.m. Thursday, July 29, 2021.  Ozone concentrations are expected
to reach the Unhealthy for Sensitive Groups to Unhealthy range on
Wednesday and Thursday. Ozone concentrations in the Unhealthy
category are most likely from western portions of the Denver area
northward through western portions of Boulder, Longmont, and Fort
Collins; and in southern portions of Weld County including
Platteville and Greeley. Concentrations of ozone in the Unhealthy
for Sensitive Groups category are expected in all other areas of
the Front Range region. CDPHE requests 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:
https://www.colorado.gov/airquality/colorado_summary.aspx

HEALTH INFORMATION...Greater likelihood of respiratory symptoms
and breathing difficulty in active children and adults and people
with lung disease, such as asthma; possible respiratory effects in
general population. Active children and adults, and people with
lung disease, such as asthma, should avoid prolonged or heavy
outdoor exertion; everyone else, especially children, should
reduce prolonged or heavy outdoor exertion.

1010 PM MDT Wed Jul 28 2021

...AIR QUALITY HEALTH ADVISORY FOR OZONE FROM 200 PM WEDNESDAY
UNTIL 1000 PM THURSDAY...

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

WHAT...Air Quality Health Advisory for Ozone.

WHERE...northern Teller and northwestern El Paso counties. Cities
and points of interest include, but are not limited to Woodland
Park, Florissant, Colorado Springs, Manitou Springs, and Monument.

WHEN...200 PM Wednesday July 28 to 1000 PM Thursday July 29

IMPACTS...Wildfire smoke is expected to enhance ozone
concentrations across the advisory area on Wednesday and Thursday.
Ozone concentrations are expected to reach the Unhealthy for
Sensitive Groups category on both Wednesday and Thursday, during
afternoon and evening hours, before returning to more moderate
levels by late Thursday evening.

HEALTH INFORMATION...Public Health Recommendations: 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.

Routt-
1010 PM MDT Wed Jul 28 2021

...AIR QUALITY HEALTH ADVISORY FOR WILDFIRE SMOKE FROM 800 AM
WEDNESDAY UNTIL 900 AM THURSDAY...

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

WHAT...Air Quality Health Advisory for Wildfire Smoke.

WHERE...northern Routt County. Locations include, but are not
limited to Glen Eden and Clark.

WHEN...800 AM Wednesday July 28 to 900 AM Thursday July 29

IMPACTS...Areas of moderate to heavy smoke have been observed in
close proximity to the Morgan Creek wildfire in northern Routt
County Wednesday morning. Smoke concentrations should gradually
decrease late Wednesday morning as atmospheric mixing improves.
Scattered showers and thunderstorms will be possible Wednesday
afternoon, and may produce gusty erratic, gusty winds which could
send smoke in any direction. By late Wednesday evening, smoke will
begin to drain to lower elevations surrounding the fire. This will
likely bring periods of heavy smoke again to areas along Morgan
and Reed Creeks, eventually draining into the Elk River Valley and
impacting the communities of Glen Eden and Clark through Thursday
morning.

HEALTH INFORMATION...Public Health Recommendations: 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. If visibility is less than 5 miles in smoke in
your neighborhood, smoke has reached levels that are unhealthy.

.DAY ONE...Today and Tonight

Isolated thunderstorms will be possible over the southern mountains
this afternoon. Scattered thunderstorms will be possible along the
Continental Divide. The primary threat from storms will be cloud to
ground lightning. Over the San Juan mountains, locally brief heavy
rain could occur with a few of the storms.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

On Friday, there will be enough residual moisture in place to
work with strong solar heating leading to the development of
isolated to scattered afternoon and evening showers and
thunderstorms. The best coverage of storms remains expected
across the higher terrain along and west of the Continental
Divide.

Increasing storm coverage and rainfall intensity continues to be
expected across the area for Saturday, Sunday, and into early next
week, as monsoonal moisture works back into the region. This will
lead to an increasing potential of flash flooding across the region,
especially for area burn scars, through early next week.
