Synopsis 24 757 am.

High pressure building over the next few days will allow for the near
normal temperatures today to warm on Sunday and remain warm into
next week. Night to morning coastal clouds will be less prominent
over the the next few days, becoming more widespread along the
coast into next week.

Short term (tdy-mon) 24 937 am.

The marine inversion early this morning had shrunk to surface-based
at vbg and to around 700 ft deep or so at lax. This plus offshore
gradient trends had greatly minimized low cloud coverage this
morning with just some low clouds over the sba county central coast,
and just patchy low clouds along the sba vtu l.A. County coast. Any
leftover low clouds will clear off the coast by mid morning.

Otherwise, mostly sunny skies covered the forecast area this morning
with little change expected thru this afternoon. NAM forecast
onshore gradients of +6.4 mb lax-dag this afternoon should promote
locally gusty s-w winds across the foothills, mtns and deserts .

Temps will be much warmer today and are expected to top out a few
degrees above normal in the warmest vlys. Expected highs range from
the upper 60s to low 70s along the immediate coast, mid 70s to mid
80s over the inland coastal plain, 90s to near 100 in the vlys and
lower mtns, and upper 90s to 102 in the antelope vly.

Through mon, the forecast area will be under the southern portion of
an elongated upper level ridge extending from off the NRN ca coast
thru central and sern ca into az. H5 heights over the forecast area
will be in the 593-595 dm range thru the period. There will be
generally weak SE flow aloft, but any monsoonal moisture will
continue to remain far to the E of the region.

The marine inversion will likely remain surface-based at vbg and 600-
800 ft deep or so at lax tonight thru mon. Night and morning low
clouds and fog should affect the central coast tonight thru mon
morning, with some low clouds also expected mainly for the vtu l.A.

County coastal areas. Patchy dense fog will be possible with any low
clouds during the period as well. Otherwise, mostly clear skies will
prevail tonight thru mon, altho a few mid level clouds may move into
the area from the S Sun and Sun night.

Afternoon onshore gradients (lax-dag) are forecast by the NAM to be
around +6.7 mb Sun and +7.2 mb mon. These gradients will continue to
promote locally gusty S to W winds each afternoon and early evening
across the foothills, mtns and deserts.

With decent warming in the boundary layer and 950 mb level, and high
1000-500 mb thicknesses (582-586 dm), temps away from the coast are
forecast to warm further Sun and Mon to about 4-8 deg above normal
away from the coastal plain. Highs each day for the warmest vlys and
lower mtns will be in the mid 90s to about 102.

As far as tropical storm ivo... As of 8 am pdt, the center was about
350 miles wsw of the southern tip of baja ca. Ivo will continue to
weaken as it continues to move nnw parallel to baja. Ivo is expected
to be downgraded to a tropical depression sometime late tonight into
Sunday morning as it continues to enter cooler waters. The only
affect for SRN ca from ivo will be surf related. See the "beach
discussion" below for more details.

Long term (tue-fri) 24 316 am.

High pressure will will continue to dominate the weather pattern
through the extended period. With onshore gradients expected to
remain moderately strong, high temps should remain slightly above
seasonal norms through the extended period (tue-fri). Not
expecting any high cloud remnants from ivo any longer as models
keep north of the area as it gets picked up in the westerlies on
tue wed. There will continue to be night through morning low
clouds across most coastal areas and santa ynez valley through
the period, otherwise mostly clear. Maybe a slight chance for
stratus to squeeze into the san gabriel vally tue-thu.

Aviation 24 1713z.

At 1700z, the marine inversion at klax was based at 1000 feet.

The top of the inversion was 3700 feet with a temperature of
24 degrees celsius.

Overall, high confidence in 18z valley desert tafs, but only
low to moderate confidence in coastal tafs. Shallow marine
inversion will keep any stratus fog confined to coastal sites
tonight. However, confidence in coastal tafs is low as there is an
equal chance of either clear conditions or ifr lifr conditions.

Klax... Overall, moderate confidence in 18z taf. High confidence in
vfr conditions through this evening. For tonight, moderate
confidence in return of stratus fog, but low confidence in timing
(could be + - 4 hours of current 10z forecast) and flight category
(could be either ifr or lifr).

Kbur... Overall, high confidence in 18z taf. There is a 10% chance
of ifr lifr conditions 11z-15z.

Marine 24 807 am.

For all the coastal waters, high confidence in current forecast.

Today through Wednesday, winds and seas are expected to remain
below small craft advisory (sca) levels.

A large southeast to south swell from tropical storm ivo will
affect the waters Sunday through Tuesday. Swell will likely
peak between 3 and 5 feet, with a slight chance of swell peaking
between 5 and 7 feet. A swell from this direction would cause
strong surges around and inside the vulnerable harbors, especially
avalon and san pedro long beach. Large breaking waves near the
coast are also likely, which has a history of capsizing small
drifting boats.

Beaches 24 807 am.

Tropical storm ivo, currently about 300 miles wsw of cabo san
lucas, will generate a southeasterly to southerly swell which will
reach the coastal waters california Sunday and persist through
Tuesday. The peak of the swell should occur Sunday afternoon
through Monday morning with a period around 14 seconds. The peak
of the swell heights will most likely fall between 3 and 5 feet,
with a slight chance of swell heights reaching 5 to 7 feet.

Dangerous rip currents and large breaking waves on rock jetties
are certain. Surf heights should reach at least 4 to 6 feet over
south facing beaches, with a chance of peak surf reaching 6 to 8
feet especially for los angeles county, which would require a high
surf advisory.

There is a risk of some coastal flooding as well. The highest
tides will be late in the afternoon, and should reach 5.7 to 6.7
feet. If the peak swell ends up between 4 and 5 feet as expected,
flooding impacts would be mostly minor and mainly in the form of
beach erosion and minor overflow. If the swell heights ends up in
the 5 to 7 foot range, which is much less likely, more impactful
flooding would be expected for vulnerable areas like pebbly beach
in avalon and unprotected parts of the long beach peninsula.

Lox watches warnings advisories
Ca... Beach hazards statement in effect from late tonight through
Tuesday morning for zones 40-41-87. (see laxcfwlox).

Pz... None.

Hazard potential outlook (mon-fri)
Elevated surf and strong rip currents are possible at area beaches
early next week.
