stay near occupied lifeguard towers. Rock jetties can be deadly
in such conditions, stay off the rocks.

* WHAT...The South Coast AQMD has issued an air quality alert due to
harmful levels of ozone pollution.
Visit https://www.aqmd.gov/alertinfo to check current and forecasted
air quality levels.

* WHERE...in the South Coast Air Basin and Coachella Valley. Levels
of ozone pollution can vary by time and location depending on
emissions and air pollution transport.

* WHEN...until 8 PM Monday. The highest ozone levels typically occur
in the afternoon and early-evening hours.

* IMPACTS... Ozone air pollution can cause serious health problems,
including trouble breathing, asthma attacks, and lung damage.
Everyone can be affected, but sensitive groups such as people with
lung disease, older adults, people who are pregnant, children, and
those who spend a lot of time outdoors are at greater risk.

To protect your health, check air quality levels and act as needed:

* When Air Quality Index (AQI) levels are "Unhealthy for
Sensitive Groups" (orange), sensitive groups as specified
above should limit extended or intense outdoor activity.
* When AQI is "Unhealthy" (red), everyone may experience health
impacts. Sensitive groups should avoid extended time outdoors.
* When AQI is "Very Unhealthy" (purple), sensitive groups should
avoid all outdoor physical activity. Everyone else should
avoid extended or intense outdoor activity.
* When AQI is "Hazardous" (maroon), everyone should avoid all
outdoor physical activity.

* ADDITIONAL DETAILS...

To help keep indoor air clean when air quality is poor:

* Keep windows and doors closed
* Run your air conditioner and/or an air purifier
* Do not use whole house fans or swamp coolers that bring in
outside air if you have other methods to stay cool
* Avoid other sources of pollution such as fireplaces, candles,
incense, and grilling

To help minimize outdoor ozone air pollution levels:

* Limit the use of gasoline powered lawn and garden equipment
until evening hours
* Try to delay trips to the gas station and the use of household
chemicals until the evening
