Synopsis 25 309 am.
Warmer than normal high temps will continue through much of the
week for inland areas as high pressure builds across the region.
There will be some high clouds from remnants of ivo tonight into
Monday. A shallow marine layer in place will allow night through
morning low clouds to likely stay confined over coastal areas
through Tuesday but could reach the santa ynez valley.
Short term (tdy-tue) 25 304 am.
Latest fog product imagery indicated mostly clear skies across the
forecast area except across the santa barbara south coast and
starting to push in across the ventura county coastal areas.
Across los angeles county, low clouds were clinging along the
coast and adjacent coastal waters but are expected to start
pushing in across portions of the l.A. Basin later this morning.
So far the central coast has remained clear but widespread stratus
was moving south along the coast and should affect some beach
locations this morning. For now have left low clouds out of santa
maria and san luis obispo this morning. There is a chance that low
clouds start to surge in across the central coast around sunrise
and will adjust forecast if needed.
Synoptically, an elongated upper level ridge (592-595 dm)
extending west to east from the eastern pac to new mexico will
persist through Monday. After that, high pressure located over
az nm will expand westward across southern california and persist
for much of the week. High temps are expected to trend higher
over the next few days with Monday and Tuesday being the warmest
with triple digit heat across the antelope valley, salinas river
valley including paso robles and woodland hills could reach 100 on
Tuesday. Coastal areas will remain fairly mild with highs ranging
in the 70s to mid 80s inland through the short term period. Night
through morning low clouds will continue to affect most coastal
areas and possibly slide into the santa ynez valley and to a less
extent the san gabriel valley as the marine layer should remain
between 700-1100 ft deep.
Meanwhile, tropical depression ivo was located 375 miles S of san
diego at 2 am pdt. Ivo will continue to downgrade to a remnant
low later today. Besides elevated surf expected today through
Tuesday across south facing beaches, the upper level ridge will
be strong enough to keep the remnant low to the southwest or west
of southern california tonight into Monday. There will be some
high clouds from ivo moving across the southern half of the
forecast area later tonight into Monday with no precip expected.
Long term (wed-sat) 25 319 am.
The upper level ridging will continue to build back into the area
wed and Thu as the strongest part of the high will be over socal
with a 594-596 dm high through Friday before weakening slightly in
strength but remaining right over socal. Strong high pressure
aloft will cause subsidence in the atmosphere keeping the marine
layer pretty shallow likely below 800 ft. Low clouds and fog, some
dense will remain limited to coastal areas through the extended
period (wed-sat)otherwise, mostly clear skies will continue
across the forecast area thru the extended period.
Temps will continue to be several degrees above normal away from the
immediate coast Wed thru sat. Highs in the warmest vlys and lower
mtns should be generally in the 90s to near 100 each day. With the
antelope valley ranging from 100 to 105.
Aviation 24 2357z.
At 2315z at klax, the marine layer was 800 ft deep. The top of
the inversion was 2300 feet with a temperature of 28 c.
High confidence in 18z valley desert tafs.|
Low confidence in coastal tafs. There is a 40 percent chc of no
cigs at any given site. If CIGS do arrive they could come in + - 2
hours from forecast time.
Klax... Low confidence in taf. There is a 40 percent chc of no
cigs. If CIGS do arrive it could be anytime between 10z-14z. There
is a 30 percent chc of ovc004 12z-15z. Very good confidence of no
east wind component.
Kbur... High confidence in cavu taf.
Marine 25 323 am.
For the outer waters, moderate to high confidence in the forecast.
High confidence in winds and seas remaining below small craft
advisory (sca) levels thru wed. On thu, there is a 60% chance of
sca level winds during the afternoon and evening hours.
For the inner waters north of pt. Sal, moderate to high
confidence in the forecast. High confidence in winds and seas
remaining below SCA levels thru wed. On thu, there is a 30% chance
of SCA level winds during the afternoon and evening hours.
For the inner waters south of pt. Conception, moderate to high
confidence in the forecast. Conditions are generally expected to
remain below SCA levels thru thu.
Patchy dense fog with visibility of one nautical mile or less is
across the coastal waters this morning and again during the late
night thru morning hours Mon and tue.
A moderate southeast to south swell from former tropical storm ivo
will affect the waters through early tue. Swell will likely peak
between 3 and 5 feet. A swell from this direction could cause some
surges around and inside vulnerable harbors, especially avalon
and san pedro long beach. Moderately large breaking waves near the
coast are possible, capable of capsizing small drifting boats.
Beaches 25 314 am.
Former tropical storm ivo, currently about 450 nautical miles wnw
of cabo san lucas, will generate a southeasterly to southerly
swell which will bring elevated surf to south facing beaches
The peak of the swell across the coastal waters should occur this
afternoon through Monday morning at between 3 and 5 feet with a
period of between 11 and 14 seconds.
Surf heights are expected to average 4 to 6 feet on south facing
beaches of los angeles and ventura counties. Dangerous rip
currents are likely, as are large breaking waves on rock jetties.
There is a low risk of minor tidal overflow near the times of
high tide on susceptible low lying beaches. The highest tides
will be late in the afternoon and evening today and Monday, and
should reach 5.7 to 6.7 feet. There may be some beach erosion as
Lox watches warnings advisories
Ca... Beach hazards statement in effect through Tuesday morning for
zones 40-41-87. (see laxcfwlox).
Hazard potential outlook (tue-sat)
Elevated surf and strong rip currents are possible at area beaches
early next week.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
