COC043-091500-
Fremont-
810 PM MDT Wed Jul 8 2020
...AIR QUALITY HEALTH ADVISORY FOR WILDFIRE SMOKE FROM 800 PM
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...eastern Fremont County. Locations include, but are not
limited to Canon City, Lincoln Park, and Brookside.
WHEN...800 PM Wednesday July 08 to 900 AM Thursday July 09
IMPACTS...As the wind decreases Wednesday evening, smoke from the
YMCA wildfire will begin to drain into lower lying areas
surrounding the fire, including the Arkansas River and Grape
Creek. Periods of moderate to heavy smoke will be possible in
Canon City, Lincoln Park, and Brookside overnight Wednesday night
and through early 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.

...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 08 to 400 PM Thursday July 09
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 9, 2020. Ozone concentrations should
generally remain in the Moderate category throughout the Front
Range region on Wednesday. However, higher ozone concentrations
are expected on Thursday with some areas possibly reaching the
Unhealthy for Sensitive Groups category. Ozone concentrations in
the Unhealthy for Sensitive Groups category on Thursday are most
likely for the south and west suburbs of Denver, including
Highlands Ranch and Golden. 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:
https://www.colorado.gov/airquality/colorado_summary.aspx
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.

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.
.DAY ONE...This Afternoon and Tonight
Critical fire weather conditions are expected over the mountains,
mountain valleys, and Fremont County this afternoon due to gusty
winds and low relative humidity. Near critical fire weather
conditions are expected over the southern I-25 corridor, but wind
speeds are anticipated to be too weak to be considered critical.
Very hot temperatures are forecast across the eastern plains this
afternoon with widespread +100F temperatures.
.DAYS TWO THROUGH SEVEN...Thursday through Tuesday
Hot temperatures will spread across southern Colorado with
temperatures topping 100 degrees at times across the southeast
plains through Tuesday. Isolated thunderstorms will return to the
forecast Saturday through Tuesday. Thunderstorms will be high
based with the potential for gusty winds up to 50 mph and
lightning, but only spotty light rainfall, particularly over the
mountains. The southeast plains may see a better chance for some
localized heavier precipitation on Sunday, but most areas will
stay fairly dry.
Spotty critical fire weather conditions will be possible at times
across the mountain valleys on Thursday, but breezy conditions do
not look sufficiently sustained for widespread critical fire
weather concerns.
.SPOTTER INFORMATION STATEMENT...
Weather spotters will not be needed today or tonight.

Fire danger will be very high in the mountains and high valleys this

outdoors today should stay well hydrated by drinking plenty of
water, and seek shade if possible.
.DAYS TWO THROUGH SEVEN...Thursday through Tuesday
Much of the upcoming week will feature hot temperatures and drier
conditions. Fire danger will be elevated once again on Friday with
high temperatures and low relative humidity values. Temperatures
