...HIGH WIND WARNING IN EFFECT UNTIL 8 PM PDT THIS EVENING...
...BLOWING DUST ADVISORY REMAINS IN EFFECT UNTIL 8 PM PDT THIS
EVENING...
...WIND ADVISORY REMAINS IN EFFECT UNTIL 1 AM PDT SUNDAY...

The National Weather Service in Phoenix has issued a High Wind
Warning, which is in effect until 8 PM PDT this evening. 

* AFFECTED AREA...Imperial county including Interstate 8, 
  Highway 111, and Highway 78. 

* TIMING...Saturday afternoon through early Sunday morning.

* WINDS...25 to 35 mph with gusts up to 45 mph. Favored terrain
  areas near and to the west of El Centro and Imperial along I-8
  will see the strongest winds with sustained winds in excess of
  40 mph and gusts as high as 60 mph through around 8 pm. Winds
  will gradually taper off through the evening hours. 

* VISIBILITY...Below 1 mile.

* Impacts...Elevated winds and strong gusts will create 
  dangerous driving conditions for high profile vehicles along 
  Interstate 8 and throughout Imperial County. Locally reduced 
  visibilities will also be possible due to blowing dust and 
  sand. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

Be ready for a sudden drop in visibility. If you encounter
blowing dust or blowing sand on the roadway or see it
approaching, pull off the road as far as possible and put your
vehicle in park. Turn the lights all the way off and keep your
foot off the brake pedal.

Remember, pull aside, stay alive.

A High Wind Warning means a hazardous high wind event is expected
or occurring. Sustained wind speeds of at least 40 mph or gusts
of 58 mph or more can lead to property damage. 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
