Synopsis 20 1025 pm.

There is a chance of snow showers in the ventura and los angeles
county mountains through this evening. Otherwise conditions will
be dry across the region this week. Winds will be breezy then gusty
santa ana winds will develop Tuesday morning. Temperatures will be
cool today then there will be a warming trend during the week.

Short term (tdy-wed) 21 935 am.

Strong and gusty NW to N winds persisted over the mtns and foothills
this morning, with gusts up to 50 mph noted at camp 9 raws as of 8
am. For the vtu l.A. County vlys, there were some gusts over 35 to
40 mph noted, such as at the saugus raws. These winds will persist
thru day in the mtns and many foothill areas, with widespread wind
advisories continuing.

Lingering upslope clouds and isolated snow showers can be expected
along the N mtn slopes into this afternoon. There is a winter
weather advisory in effect for the N mtn slopes of vtu l.A. Counties
until noon pst due to expected light snow accumulations, but this
will likely be allowed to expire by noon or even cancelled before
noon as very little precip has been noted in the area this morning.

Otherwise, mostly sunny skies will prevail today across southwestern
ca. It will be a rather cool day with below normal temps as highs
reach only into the upper 50s to low 60s for much of the coast
and vlys, and upper 40s to low 50s in the antelope vly.

A rather potent inside slider upper level trof was over eastern
ca this morning and will gradually move off to the SE thru
tonight. An upper level ridge of high pressure will build off the
ca coast late tonight and Tue then edge closer to the coast thru
wed, with 500 mb heights over SW ca increasing to near 584 dm on
wed.

The strong and gusty NW to N winds will transition to N to ne
tonight and Tue and affect the mtns, foothills and many vlys of
vtu l.A. Counties, with additional rounds of gusty NE winds
expected Tue night into Wed morning. These areas are under an
extended wind advisory through Wed morning. For the sba county s
coast and mtns, gusty N winds can be expected through Tue morning,
especially below and thru the passes and canyons, where wind
advisories are in effect thru the period. The antelope vly can
expect strong and gusty W to NW winds thru this afternoon, with
gusty N winds for the san gabriel vly and l.A. County coast
especially from malibu to the hollywood hills. Wind advisories are
in affect for these areas through this afternoon. Expected wind
gusts range from 45 to 55 mph in the deserts, mtns and foothills,
and generally 35 to 45 mph elsewhere in the advisory areas.

Please see the latest non-precipitation weather message
(laxnpwlox) for further details on the ongoing wind advisories.

There should be residual clouds and isolated snow showers on the n
mtns slopes into this evening, otherwise mostly clear skies will
prevail across the forecast area tonight through wed. Temps are
forecast to still be only near normal to slightly below normal on
tue, then rebound to near normal to slightly above normal for many
areas on wed. Look for highs in the warmest vlys and inland coastal
areas to reach the mid 60s on tue, and upper 60s to low 70s on
wed. Low temps will also be quite cool the next couple of nights
with the coldest sheltered vlys dropping to near or slightly above
freezing. However, widespread frost is likely for the slo county
interior vlys, with freezing conditions in the mid to upper 20s
expected for the antelope vly.

Long term (thu-sun) 21 309 am.

Both the ec and GFS agree that the state will be under the
eastern half of an east pac high for the entire time thu-sun. Sfc
high pressure remains anchored over the great basin through the
period and there will be varying degrees of offshore flow through
the period. Right now it looks like Friday will have the strongest
offshore flow and some low end advisories may be needed then.

The ridge and the offshore flow should keep skies mostly clear
through the period. The higher than normal hgts combined with the
offshore flow will bring well above normal temps to the area for
all four days. Currently Saturday is slated to be the warmest of
the next 7 with mx temps 8 to 12 degrees above normal.

Aviation 21 1030z.

At 1030z, there was no marine inversion at klax.

Overall, moderate to high confidence in 12z TAF package. High
confidence inVFR sky conditions for all sites through the taf
period with sct-bkn040-060 deck possible through 20z. Moderate
confidence in wind forecast due to some uncertainty of the timing
of changes in strength direction. There is 40% chance of some MVFR
vsbys in blowing dust sand at kwjf kpmd 16z-02z.

Klax... Moderate confidence in 12z taf. High confidence inVFR
conditions through TAF period. Moderate confidence in timing of
changes in wind strength direction. There is a 50% chance of
northerly cross winds around 15 knots 03z-12z.

Kbur... Moderate confidence in 12z taf. High confidence inVFR
conditions through TAF period. Moderate confidence in timing of
changes in wind strength direction.

Marine 21 230 am.

For the outer waters, moderate confidence in current forecast.

Strong small craft advisory (sca) level northwest winds will
continue through tonight with a 20% chance of gale force gusts. On
Tuesday, there is a 30% chance of SCA level winds then winds and
seas are expected to remain below SCA levels Wednesday through
Friday.

For the inner waters north of point sal, high confidence in
current forecast. SCA level northwest winds will continue through
tonight. For Tuesday through Friday, winds and seas are expected
to remain below SCA levels.

For the inner waters south of point conception, moderate
confidence in current forecast. High confidence in SCA level west
to northwest winds through this evening. For Tuesday and
Wednesday, there is a 60% chance of SCA level northeast winds from
point mugu southward. For Thursday and Friday, winds and seas are
expected to remain below SCA levels.

Beaches 21 230 am.

A new west to northwest swell will move into the coastal waters
today. These swells will produce elevated surf and strong rip
currents on west-facing beaches through Tuesday. Large
astronomical high tides are also be expected each morning through
this time, peaking today. Due to the higher than normal tides and
elevated surf, there could be minor coastal flooding near the
times of the morning high tide each day. As a result of the
elevated surf and potential for minor coastal flooding, a beach
hazards statement is in effect for all west facing beaches through
Tuesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
