Synopsis
Strong onshore flow will weaken today with scattered light showers
along and west of the mountains ending this morning and with
strong west winds in the mountains and deserts decreasing this
afternoon. The flow will turn offshore late tonight into Tuesday
morning with generally offshore flow continuing into next weekend.

There will be periods of gusty northeast winds near and along and
near the coastal slopes of the mountains. After cooling today, high
pressure aloft along the west coast combined with the offshore
flow will bring a warming trend for Tuesday into next weekend.

Discussion For extreme southwestern california including orange...

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

Short term (today through Wednesday)
A trough of low pressure over the western states will continue to
move inland today. Strong onshore low level flow will weaken this
afternoon with the flow turning offshore and strengthening late
tonight and Tuesday.

Satellite imagery early this morning shows clouds banked up
against the mountains and extending back toward the coast. There
is also more extensive cloud cover across portions of the high
desert. A few light showers will continue early this morning near
coastal mountain slopes and for coastal and valley areas of san
diego county with a few light showers or sprinkles also possible
across portions of the high deserts.

Strong west winds in the mountains and deserts will weaken this
afternoon. The flow will turn offshore late night and Tuesday with
northeast winds developing and strengthening along and near the
coastal slopes of the mountains and below passes and canyons with
periods of gusty northeast winds continuing into Wednesday.

The stronger onshore flow will bring cooling for today.

Strengthening high pressure aloft near the west coast combined
with the offshore flow will bring a warming trend for Tuesday and
Wednesday.

Long term (Thursday through Sunday)
High pressure aloft near the west coast may move toward the west a
little by Sunday and Monday. Periods of mostly weak to moderate
offshore flow will continue into Saturday with periods of gusty
northeast winds near the coastal slopes of the mountains and
below passes and canyons, mainly late nights and mornings. The
warming trend will continue into Saturday. As high pressure aloft
shifts toward the west, that will open up the possibility of a
trough of low pressure moving southward through the western states
into the southwest states. The ECMWF is the most aggressive with
this scenario. That would bring more clouds and cooling than
currently shown in the forecast for Sunday and Monday along with
small chances for light precipitation on Monday.

Aviation...

211000z... Coast valleys mountains... Low clouds with varying bases
1500-2500 feet msl, but occasionally scattered vcnty ksna. Isold -
shra in san diego county. Vis 3-5sm in -shra and in valleys and
coastal slopes. Areas of higher terrain obscured in fog and -shra.

West winds will increase this morning, with gusts 20-25 kt through
the afternoon, then transitioning to E NE winds tonight.

Mountains deserts... West winds 25-35 kt with gusts to 50 kt
producing stg uddfs and local llws over and east of the ridges.

Winds weaken this afternoon before turning NE and strengthening
overnight.

Marine
Windy, choppy conditions and hazardous combined seas feet will
produce hazardous boating conditions today and tonight. For details,
check the small craft advisory in effect. Northwest winds today will
turn northeast early Tuesday morning with a few gusts over 20 kt
between san mateo point and san clemente island through midday. No
additional marine weather hazards are expected later Tuesday through
Friday.

Beaches
Very high tides will happen this morning and again Tuesday morning.

Higher than average surf will build today and diminish Tuesday. The
combination of these factors may produce minor coastal flooding at
the beaches. Check the beach hazards statement and surf zone
