...AIR QUALITY ALERT FOR ELEVATED OZONE AIR POLLUTION THROUGH 7 PM
WEDNESDAY...

The South Coast AQMD has extended an air quality alert in the inland parts
of the South Coast Air Basin and the Coachella Valley due to high
levels of ozone (smog). The air quality alert is in effect until 7 PM
Wednesday.

Elevated levels of ozone  the predominant summertime pollutant
are likely to result in poor air quality in the afternoon and early-
evening hours. Ozone air pollution can cause respiratory health
problems, including trouble breathing, asthma attacks, and lung
damage. Children, older adults, and people with asthma or COPD may
be more sensitive to the health effects of ozone.

Air quality can change depending on time of day and weather
conditions. Increased emissions of chemicals and faster ozone
formation rates due to heat, along with low winds and stagnant
weather can cause unusually high and persistent levels of ozone
pollution.

To help minimize ozone air pollution levels:
* Limit the use of gasoline powered lawn and garden equipment until
evening hours
* Conserve electricity and set your air conditioner at a higher
temperature
* Try to delay trips to the gas station and the use of household
chemicals until the evening

Check air quality levels and take appropriate action as needed.
When air quality index (AQI) levels are Unhealthy for Sensitive
Groups (orange), people with heart or lung disease, pregnant women,
children, and older adults should limit prolonged or heavy outdoor
exertion. When air quality reaches Unhealthy (red) AQI levels,
everyone may experience adverse health effects and sensitive groups
should avoid prolonged time outdoors. At Very Unhealthy (purple) AQI
levels, sensitive groups should avoid all outdoor physical activity
and everyone else should avoid prolonged or heavy outdoor exertion.

...AIR QUALITY ALERT DUE TO ELEVATED PARTICLE POLLUTION LEVELS FROM
WINDBLOWN DUST THROUGH 8 AM TUESDAY...

The South Coast AQMD has issued an air quality alert due to
increased particle pollution from blowing dust. The air quality
alert is in effect through 8 AM Tuesday.

In areas directly impacted by high levels of windblown dust, limit
your exposure by remaining indoors with windows and doors closed and
avoiding vigorous physical activity. Run your air conditioner or an
air purifier. If temperatures allow, avoid using whole house fans or
swamp coolers that bring in outside air.

Exposure to high particle pollution levels can cause serious health
problems, including asthma attacks, heart and lung disease symptoms,
and increased risk of respiratory infections. People with heart or
lung diseases should follow their doctor`s advice for dealing with
episodes of unhealthy air quality. Children, older adults, and
people with respiratory or heart disease should avoid prolonged
exposure and strenuous activities when particle pollution levels are
high.

To help minimize outdoor particle pollution levels:
* Carpool, telecommute, reduce trips, or take public transportation
* Slow down if driving on dirt roads
* Stabilize loose soils

Levels of particle pollution can vary hour by hour and by location
depending on wind conditions.
