* WHAT...West winds 20 to 30 mph with gusts up to 45 mph
expected.

* WHERE...Western portion of Joshua Tree National Park,
Southeastern Imperial County, Western Imperial County, Salton
Sea, Chuckwalla Mountains, Imperial Valley, and Chiriaco
Summit.

* WHEN...From 5 PM this afternoon to 5 AM PDT Sunday.

* IMPACTS...Difficult driving conditions, especially for larger
vehicles traveling along roads with crosswinds. Light,
unsecured objects may become airborne.

A Wind Advisory means that sustained wind speeds of between
30 and 40 mph are expected, or wind gusts of between 40 and
58 mph. Winds this strong can make driving difficult, especially
for high profile vehicles.

In addition, strong winds over desert areas could result in
briefly lowered visibilities to well under a mile at times in
blowing dust or blowing sand. Use extra caution.

* WHAT...West winds 25 to 35 mph with gusts up to 50 mph expected.
Isolated gusts to 65 mph through the passes.

* WHERE...Apple and Lucerne Valleys, Coachella Valley, San Diego
County Deserts, and San Gorgonio Pass near Banning.

* WHEN...From 2 PM this afternoon to 11 AM PDT Sunday.

* IMPACTS...Gusty winds will blow around unsecured objects. Tree
limbs could be blown down and a few power outages may result.
Locally reduced visibility in blowing dust.

Winds this strong can make driving difficult, especially for high
profile vehicles. Use extra caution.

Secure outdoor objects.

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

* WHERE...in the Coachella Valley. Levels of particle pollution can
vary by time and location depending on emissions and local weather
conditions.

* WHEN...from 5 PM Friday to 11 AM Sunday.

* IMPACTS... Particle pollution can get deep into the lungs and
cause serious health problems such as asthma attacks, heart and
lung disease symptoms, and increased risk of lung infections.
Everyone can be affected, but sensitive groups such as people with
lung or heart 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, grilling, and gasoline-powered lawn and garden
equipment

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
