Synopsis for the far southern california coast.. West northwest winds will be strong with gusts to around 25 knots today. A brief lull between storm systems late Monday into early Tuesday will allow for winds to weaken slightly. However, the break will be short-lived as the second system arrives Tuesday afternoon into Wednesday, generating gusty northwest winds that may approach gale force at times, particularly over the outer waters. Combined seas will also be high, 10 ft or higher, during this period. Winds and seas will then diminish Thursday into Friday as high pressure builds over the region.

Synopsis
Showers will diminish this morning, but isolated showers are to
continue in the mountains. Partly cloudy and cool conditions for
most of today. Winds will be strong and gusty over all of the
mountains, deserts, and coastal waters all the way through
Tuesday night. Scattered light showers are expected at times
through Thursday. Snow in the mountains is possible Wednesday. A
deep marine layer will remain in place through the week due to a
strong onshore flow pattern, with daytime temperatures remaining
well below seasonal averages. Another low pressure system looks
to bring showers and winds again over the weekend.

Discussion For extreme southwestern california including
orange... San diego... Western riverside and southwestern san
bernardino counties...

a somewhat organized band of showers moved through the region
overnight, and fewer scattered showers continue this morning.

Since midnight these have been mainly over higher coastal terrain
and from the valleys to the mountain crests. Snow showers have
been noted above 6,000 feet, but with only an inch or two
accumulating overnight. We expect showers to gradually diminish
fron north to south during the morning. If you haven't already,
get comfortable with the cool and showery weather. A giant low
pressure trough over the western states has and will continue to
dominate our weather pattern this entire coming week. Within that
large trough will be shortwaves rotating and energizing the cool
moist air mass to produce occasional showers. Most of these appear
light. And with the waves coming out of the north, the wind
directions and moisture trajectories favor san diego county more
than areas farther north. After this morning we dry out a bit
before the next wave enhances our deep marine layer and our
chances for drizzle or light showers early Tuesday. This chance
increases later Tuesday into early Wednesday. Colder air aloft
under that next wave will help showers to generate Wednesday, but
mostly in the mountains with even isolated showers in the desert.

Mainly marine layer showers Wednesday night into Thursday might
be followed by a dry period Friday into Saturday. Snow levels
could drop to 6,000 feet again early Wednesday, but with little
accumulation above that level. Winds will continue rather strong
today, just not as strong as last evening. Winds will actually
strengthen Tuesday, particularly during the afternoon and evening
when top gusts in the windiest areas will exceed 55 mph. Hence,
the wind advisory rides through Tuesday night. Winds decrease
Wednesday. After the light showers Thursday, the weather won't be
warm and pretty Friday into Saturday, but it does look like a
break from showers and winds. The next wave on the horizon in our
eternal and stationary trough appears Sunday. Models of course
differ in details, but there is some consensus for a decent chance
of showers and some strong winds right in the middle of the
memorial day weekend. Some guidance hints that the long wave
trough might nudge eastward next week for drier and warmer weather
starting on memorial day. But stay tuned on that; your holiday
forecast may vary for at least the coming few days.

Aviation
200900z... Coast valleys... A few shra will move from NW to SE across
the area, most prevalent over the valleys. Brief CIGS to about 2000
ft msl will occur in the showers along with vis reductions to 2-4sm.

Otherwise,VFR will prevail. Areas of lower CIGS of 2500-3000 ft msl
will develop near the coast, potentially affecting ksan and kcrq
after 06z Tuesday (moderate confidence).

Mountains deserts... Coastal mountain slopes will be obscured in
cloud cover. Strong w-nw winds with gusts in excess of 50 kt will
continue with gusts to 30 kt to parts of the deserts. Moderate to
severe updrafts and downdrafts will occur east of the mountain
crests. Winds have rotared in the lower deserts with east winds at
kpsp early this morning, so quickly changing speeds and surface wind
direction will continue to be possible. Winds will relax a bit this
afternoon before picking back up again tonight-Tuesday with strong
winds along the desert mountain slopes.

Marine
A small craft advisory remains in effect through 3 pm Wednesday.

Hazardous marine conditions will continue this period with winds
peaking this morning and another wind surge arriving Tuesday
afternoon and peaking Tuesday night when NW wind gusts of 30-35 kt
are possible over the outer waters. Winds will gradually relax late
in the week along with subsiding seas.

Beaches
Building medium-period wnw swell will generate locally elevated surf
conditions today through early Tuesday, with surf up to 7 ft,
especially in southern san diego county. A beach hazards statement
is in effect from 3 am today through 9 am Tuesday.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.
