Synopsis 23 257 am.

A strong eddy circulation across the coastal waters will bring
below normal temperatures across much of the forecast area today.

High pressure will build in this weekend allowing for a warming
trend through at least early next week. High temperatures will be
a few degrees above normal by this weekend. Expect night through
morning low clouds and fog to continue across many coastal areas
this weekend with some coastal valleys could experience some low
clouds as well. Warmer than normal temperatures away from the
coast will continue into next week.

Short term (tdy-sun) 23 321 am.

Latest goes-w fog product imagery indicated widespread low clouds
across all coast and coastal valleys as well as the santa clarita
valley. The marine layer has deepened to around 2400 ft early this
morning mainly due to a relatively strong catalina eddy. The
southerly surge of winds affecting the socal bight will continue
to push low clouds farther north around point conception and
across the central coast into the afternoon hours. Expect low
clouds to be a little slower to scour out across coastal locations
today. Most areas will be 3 to 8 degrees cooler compared to
yesterday with the interior valleys of slo county lowering 15
degrees. The one exception will be the southern portion of the
central coast as some downsloping across the santa ynez range is
expected with southerly flow. The high at paso robles is expected
to be 84 degrees compared to 98 yesterday due to the cooler
southerly flow. Most valleys will reach the mid 80s to lower 90s
while the antelope valley will be in the mid to upper 90s.

By Saturday, high pressure aloft will build in and become
elongated NW to SE across the eastern pac and much of california
and into arizona. This will cause the upper trough to redirect
farther north across the pac nw. At the surface, onshore gradients
will trend weaker each day from Saturday to Sunday allowing for
temps to climb 3-6 degrees Saturday with further warming 2-4
degrees. The one exception will be across the salinas river valley
including paso robles where high temps will rebound quite nicely
from the 84 forecast for today, to the lower 90s on Saturday then
close to 100 on Sunday. The marine layer will become more shallow
due to the stronger subsidence from the 594 dm high over the
region. Expect low clouds to affect coastal areas as well as the
santa ynez valley. Some low clouds could creep into a few coastal
valleys across l.A. And ventura counties through the weekend.

As far as tropical storm ivo (pronounced "eye-vo") the location as
of 2 am pdt was around 455 miles SW of the southern tip of baja
california. Ivo will turn to the nnw following a path parallel
to baja through early Sunday morning. As ivo reaches the cooler
waters off the mid baja peninsula, it is expected to weaken
rapidly to a depression. High pressure situated over much of
california will push the remnants of ivo to the wsw of southern
california Sunday night into Monday. There will be a few mid to
high level clouds moving across the forecast area Sunday evening
into Monday but not expecting any weather related issues, except
increasing surf across south facing beaches. See the "beaches
discussion" below for more details.

Long term (mon-thu) 23 318 am.

Both the GFS and ec are in decent agreement with large scale
features through the extended period (mon-thu). With high pressure
aloft dominating the pattern through much of next week with
moderately strong onshore flow at the lower levels, high temps
should remain a few degrees above normal with only subtle day to
day fluctuations. Night through morning low clouds and fog will
continue to affect most coastal areas and the santa ynez valley. A
few coastal valleys could see some patchy low clouds as well
depending if the marine layer could deepen at times.

The GFS and ECMWF continue to show the remnants of ivo staying to
the SW to W of the forecast area Sunday night into Monday due to
the strong high pressure over socal. However persistent SE mid level
flow will remain over the area mon-wed before turning SW on Thursday.

Although nothing is showing up as far as disturbances moving north
in the southerly flow this far out, will have to continue to monitor
in case storms fire up across mexico and southern az and outflow
from these storms move into the deserts and mountains. For now it
looks dry through the extended period with variable high clouds
moving through the area.

Aviation 23 0537z.

At 0430z, the marine layer was 2100 feet deep at klax. The top of
the inversion was around 4300 feet with a temp of 234c.

Widespread low clouds expected to push into all coastal and valley
areas overnight with the exception of the far interior valleys of
slo county and the cuyama valley. There is a slight chance that a
strong eddy circulation will move westward off the coast of l.A.

County pulling the clouds out of l.A. County. Otherwise, if this
does not occur, expect rather slow clearing on fri, by late
morning in the valleys and early to mid afternoon near the coast.

Cigs will generally rise overnight into the MVFR category, but
will remain ifr to lifr for most of the night north of pt
conception.

Klax... Moderate confidence in the 06z taf. CIGS will likely
scatter out for a few hours this evening. There is a 30% chance
that CIGS will not return until at least 14z. Here is a 30% chance
that CIGS will not return Fri evening until after 07z. There is a
20% chance of east winds gusting to 15 knots between 11z and 18z.

There is a 20% chance that east winds will persist through 21z.

Kbur... Moderate confidence overall in the 06z taf. While cigs
should arrive by 08z, they may be temporary, and there is a 30%
chance that more permanent CIGS will not arrive until 14z fri.

Marine 23 318 am.

Moderate to high confidence that winds will remain well below sca
levels across the outer waters and the inner waters north of point
sal today through tue.

A strong eddy circulation will bring abnormally strong southeast
winds for august to the southern inner coastal waters and the
santa barbara channel this morning (as well as eastern portions
of the outer southern outer waters). While winds speeds will be
mostly 10 to 15 kt, peak winds of 15 and 25 kt are expected at
times between point conception and orange county at times. There
is a 50-60% chance that winds will reach SCA criteria. Otherwise,
sca conds are not expected across the inner waters south of pt
conception from this afternoon through tue.

An abnormally large south to southeast swell from tropical storm
ivo will impact the waters Sunday through Tuesday. There is a
potential for the swell to peak 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 23 320 am.

Moderate south swell with a fairly long period will bring some
elevate surf of 3 to 5 feet with local sets to 6 feet to south
facing beaches of los angeles and ventura counties today. There
will also be a high risk of rip currents.

Tropical storm ivo, currently about 500 miles southwest of cabo
san lucas, will generate a southeasterly swell reaching california
Sunday and persisting through Tuesday. The peak of the swell
should occur Sunday afternoon through Monday morning with a period
around 14 seconds. While the peak swell heights will most likely
fall between 4 and 6 feet, there is a chance for a range of 5 and
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 for impactful 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 3 to 5 feet, flooding
impacts would be minor and mainly in the form of beach erosion. If
the swell height ends up closer to 8 feet, more impactful
flooding would be expected for the vulnerable areas like pebbly
beach in avalon and the long beach peninsula if unprotected.

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

Pz... Small craft advisory in effect until noon pdt today for zones
650-655. (see laxmwwlox).

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