Onshore flow will strengthen tonight into Monday. 25 to 30 kt northwest wind gusts are likely on Monday along with combined seas of 10 feet or greater and rough seas...resulting in conditions hazardous to small craft. Locally strong and gusty northwest winds continue during the day Tuesday before winds and seas subside Tuesday night. Weak onshore flow likely on Wednesday before winds start to pick up again on Thursday and Friday with another round of potential small craft advisory conditions.

Synopsis
Areas of low clouds will continue tonigh. A low pressure trough will
bring cooling Monday and a slight chance of showers along with
locally gusty west winds. Offshore flow will develop Tuesday and
bring gusty northeast winds below passes and canyons and fair warmer
weather Tuesday through Wednesday. A low pressure trough will move
by to the northeast Thursday or Friday and bring cooling again and
gusty west winds followed by possible northeasterly winds again next
weekend.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

skies were partly cloudy with temperatures in the 60s west of the
mountains with sunny skies in the mountains and deserts and near-
seasonal temperatures there with lower 80s in the lower deserts.

With a 3500-4000 foot deep marine layer, partly to mostly cloudy
conditions will prevail west of the mountains.

A broad area of low pressure is currently off the pac NW coast, and
the trough will move e/se and dig into so-cal by Monday morning.

Moisture will be rather limited here and be mostly under 850 mb, so
any precip that occurs will be light, with best chances in san diego
county due to better westerly flow from over the water. We will
maintain the slight chances of precip for now for late tonight and
Monday morning. Local wind gusts over 50 mph will occur in the
mountains and deserts Monday due to the gradients aloft, and a wind
advisory has been issued for most of these areas starting at 4 pm
Monday. After the trough moves east late Monday night/Tuesday
morning, a surface high from the pacific will spread into nevada and
result in some moderate offshore flow. A wind advisory covers the
area from the santa ana mountains east and northeast through the
inland empire and san bernardino/riverside county mountains Monday
night through 2 pm Tuesday. Ridging from the west combined with the
marine layer becoming either very shallow or non-existent will
result in warmer days Tuesday/Wednesday.

By Thursday, the next trough will dig south over the interior
western us, but the inland track will mean that precip chances will
be quite low here, unless the trough ends up further west than what
the models show. The main effects here will be the cooler weather
and windy areas in the mountains and deserts. If the trough shifts
east without closing off over the weekend, we should have fair
warmer weather but with a possibility of offshore flow next weekend.

Aviation
261920z... 27/0300 utc, sct-bkn clouds in the 1500-3500 ft msl layer
continuing over the coast, valleys and locally over the coastal
slopes, with sct-few clouds AOA 20000 ft msl elsewhere and p6sm vis
for all areas. 27/0300-1500 utc, bkn-ovc stratus gradually re-
developing in the coast, valleys and lower coastal mountain slopes,
with bases 2000-3000 ft msl, tops 4000-4500 ft msl and local vis 3-5
sm.

After 27/0000 utc, W to NW winds strengthening, becoming 15-25 kt
with gusts 35-40 kt over the mountain ridges, desert slopes,
passes/canyons and into wind-favored desert areas, resulting in mod-
strong up/downdrafts and llws over and east of the mountains.

Marine
Northwest winds will strengthen late today through Monday as a low
pressure system passes across the region. Gusts of 25 kt are
possible beginning this evening (mainly in the outer waters) and
then gusts could reach 30 kt on Monday in both the inner and outer
waters, in addition to combined seas rising to near or above 10 ft.

Locally strong and gusty northwest winds will likely continue
through most of Tuesday before diminishing that evening. A small
craft advisory GOES into effect at 5 pm today for the outer waters,
and at 1 pm Monday for the inner waters, and continues through early
Tuesday evening.

Beaches
West-northwest swells from around 285-290 degrees will create
elevated surf of 3-6 feet through most of this week. Sets of 7 feet
will be possible at times. These surf conditions will be accompanied
by an increased risk of strong rip currents.
