Please take actions to keep yourselves and your families safe and prepared.

AM DEC 15, 2011
There will be a strong upper-level low diving south across California
today,which will reach the Mexico border after dark.  This will create a
high-wind event for southern California.  We are expecting strong
northeasterly winds to develop after midnight tonight, persisting through
Friday.  Strongest winds are still expected to occur between 4AM and 12PM
PST Friday, with some reduction in speeds Friday afternoon.  A second
peaking of the gusts will develop late Friday night into Saturday morning
(from approximately 11PM Friday through 7AMSaturday).  From 4AM-12PM
Friday, peak wind gusts will run between 50-60 mph across southern portions
of the San Gabriel and San Bernardino Mountains, passes and canyons in the
higher elevations of Los Angeles and Ventura counties, as well as the Santa
Clarita Valley.  Wind gusts to 35-50 mph will be possible in the Santa
Monica Mountains, eastern valleys of Ventura County,western portions of the
San Fernando Valley, the Ventura County Coast, and coastal sections of Los
Angeles County south of the Santa Monica Mountains including the
communities of Malibu and Hollywood Hills.  The peak gusts from11PM Friday
through 7AM Saturday morning are anticipated to run between 40-55mph across
the higher terrain, with gusts of 25-35 mph across lower elevations and
nearer to the coast. Winds will return to fairly calm by Saturday evening.
Compared to the severe wind event from a few weeks ago, this event will not
be as strong.  But with the wind gusts forecasted there could still be some
localized damage.San Gabriel Valley (Pasadena, Arcadia, Monrovia, Temple
City, Altadena):While the strongest wind gusts are anticipated to hold to
the north of the region, there will still remain the potential for strong
wind gusts over the San Gabriel Valley.  Peak wind gusts will run between
40-50 mph across areas north of the Foothill Freeway (inclusive of, but not
limited to, Altadena, Monrovia and Azusa), while gusts to the south of
there will generally peak out between25-35 mph. The time period of highest
gusts will occur between 8am and 2pmFriday with a slight decrease during
the afternoon and evening hours.  A similar peak time is expected Saturday
morning and early afternoon
