Synopsis
A santa ana wind will blow tonight through Wednesday, peaking
Tuesday morning. Periods of gusty northeast winds will occur along
the coastal slopes of the mountains and through western parts of
the inland empire and inland orange county. High pressure building
in aloft along the west coast combined with the offshore flow
will bring a much warmer trend for Tuesday into the weekend.

Discussion For extreme southwestern california including orange...

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

Update...

the strong onshore surface pressure gradient has gone offshore
this evening. Extreme wind speeds were recorded on the strong west
winds early this morning with peak wind gusts of 97 mph recorded
at burns canyon and 74 mph at whitewater. Wind damage occurred at
the king of the hammers with tents toppled damaged. Strong winds
impacted coastal locales as well with gusts this morning of 30-35
mph and some spots to 45 mph. Sadly, 2 fatalities occurred at
point loma where a large tree fell on a home.

A summary of the peak wind gusts over the past 24 hours is
headlined on our webpage and on twitter @nwssandiego
a santa ana wind now will be taking hold with peak strenght
Tuesday morning. Wind gusts of 45-55 mph will occur with peak
winds along the coastal mountain slopes, below the cajon pass with
strong winds spreading into parts of the western inland empire
and inland orange county (santa ana foothills). No significant
changes were made to the forecast. See previous discussion below
for more details.

Previous discussion (issued at 307 pm pst Mon jan 21 2019)...

strong west to northwest winds continue across the mountains,
desert slopes, and down into the deserts, with surface pressure
gradients running about 5 mb after this morning's peak gradients
around 15 mb. Gusty winds will continue through late afternoon and
the wind headlines were extended an additional two hours until 4
pm. Otherwise skies have partially cleared out and the showers
that occurred this morning have dissipated. Rainfall was light
with an inch or two of snow in the san bernardino mountains this
morning.

Offshore gradients will increase this evening and cause a cold
santa ana pattern to develop late tonight. Wind advisories remain
in effect for all of the valley and coastal-mountain slopes
through Wednesday morning. Wind gusts will become strong by
Tuesday morning, especially in the canyons and foothills. Less
upper level support for Tuesday night into Wednesday, but still
continued strong offshore gradients and thus the wind advisories
will remain in place.

Upper level ridging become strong mid to late week. A rapid warmup
for all areas west of the mountains with temperatures 10 to 15
degrees above normal. The upper level ridge remains strong through
early next week but is forecast to trend west over the eastpac.

This will allow temperatures to moderate next weekend into the
following week, with increase in upper level moisture from the
subtropics over the weekend for a transition from sunny skies to
partly cloudy skies. A lot of disagreements in the global models for
the following week with the potential for a pattern shift, although
the ec keeps with the strong eastpac ridge theme and weak onshore
flow near the coast.

Aviation
220440z... Few-sct clouds with bases 3500 ft msl clearing overnight.

Northeast winds with sfc gusts 35-45 kt developing along the coastal
mountain slopes and below the passes and canyons 08-12z, spreading
into the inland valleys and orange county coastal plain by 16z.

Strong winds will continue through the afternoon, weakening and
becoming less widespread after 23 00z. Stg-svr uddfs and pockets of
llws likely over and SW of the mountains.

Marine
Northwest winds 20-30 kt will gradually weaken through early Tuesday
morning. Combined seas of 9-11 ft over the outer coastal waters will
lower this evening as well. Winds will become north to northeast on
Tuesday as offshore flow develops. Gusts to around 20 kt are
possible through Tuesday afternoon. No hazardous marine weather is
expected late Tuesday through Saturday.

Beaches
High tides of 6.6-6.7 ft Tuesday morning, along with elevated surf
of 3-5 ft could produce minor coastal flooding at low-lying beach
areas. A beach hazards statement remains in effect through 12 pm
Tuesday.

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