...AIR QUALITY ALERT FOR ELEVATED FINE PARTICLE POLLUTION LEVELS DUE
TO WILDFIRE SMOKE...

The South Coast AQMD has issued an air quality alert due to
increased fine particle pollution from wildfire smoke in the region.
The air quality alert is in effect from 4:30 PM Saturday through
3:00 PM Sunday.

If you smell smoke or see ash due to a wildfire, remain indoors with
windows and doors closed or seek alternative shelter, if feasible.
Avoid vigorous physical activity and run your air conditioner and/or
an air purifier. If possible, do not use whole house fans or swamp
coolers that bring in outside air. Avoid burning wood in your
fireplace or firepit and minimize sources of indoor air pollution
such as candles, incense, pan-frying, and grilling. If you must be
outdoors, keep the time brief and wear a tightly-fitted N-95 or P-
100 respirator to help reduce exposure. Limit the use of gasoline
powered lawn and garden equipment.

Exposure to particle pollution can cause serious health problems,
aggravate lung disease, cause asthma attacks and acute bronchitis,
and increase risk of respiratory infections. People with heart or
lung diseases should follow their doctor`s advice for dealing with
episodes of unhealthy air quality. Additionally, people with
respiratory or heart disease, older adults, and children are
particularly susceptible and should avoid prolonged exposure,
strenuous activities or heavy exertion as conditions dictate.

Levels of particle pollution can vary hour by hour and by location
depending on fire behavior and local weather conditions.

To view current and forecasted air quality levels, visit the South
Coast Air Quality Management District website at aqmd.gov or
download the mobile app at www.aqmd.gov/mobileapp. Additional
details for this air quality alert may be available at

...OZONE ACTION DAY ALERT FROM 400 PM SATURDAY UNTIL 400 PM
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:
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.

PHOENIX METRO AREA SATURDAY AND SUNDAY...

The Arizona Department of Environmental Quality (ADEQ) has issued an
Ozone High Pollution Advisory for the Phoenix Metro Area on Saturday
and Sunday.

This means that forecast weather conditions combined with existing
ozone levels are expected to result in local maximum 8-hour ozone
concentrations that pose a health risk. Adverse health effects
increase as air quality deteriorates.

Ozone is an air contaminant which can cause breathing difficulties
for children, older adults, as well as persons with respiratory
problems. A decrease in physical activity is recommended.

You are urged to car pool, telecommute or use mass transit.
The use of gasoline-powered equipment should be reduced or done late
in the day.

the Fresno June Lightning Complex and Basin Fire in Madera, Fresno,
Tulare, and the Valley portion of Kern Counties.

dealing with episodes of unhealthy air quality. Short-term exposure
to particle pollution has been linked to heart attacks and
arrhythmias, according to the U.S. Environmental Protection Agency.

Additionally, older adults/elderly people and children are also more
susceptible to consequences of high particulate levels and should
avoid prolong exposure, strenuous outdoor activities or heavy
exertion, as conditions dictate.
