428 am pdt Thu oct 19 2017
An upper-level trough of low pressure will brush the area through
Friday night. Showers could develop over the mountains and along
the central coast tonight through Friday. Winds will increase
through Friday night as a weak cold front moves over the region,
then santa ana winds will likely develop between Saturday and
Sunday. A significant warming trend is expected for early next
week. Record heat is forecast for Monday and Tuesday.
Short term (tdy-sat)
the latest infrared satellite imagery indicates a weak
disturbance near 30n and 130w. The disturbance will increase
moisture across the area through Friday, while the disturbance
phases with a digging trough of low pressure currently near 40n
and 140w. Fog product imagery shows a marine layer stratus deck
becoming well entrenched along the central coast and offshore.
Some organization is starting to develop with stratus over
southern los angeles county and into the san pedro channel. A
more developed marine layer stratus deck should occur through
Friday as the trough's cold front approaches the area.
With the increasing moisture ahead of the front, shower activity
cannot be ruled out for the central coast and interior portions
of the area, including the north slopes of the transverse
mountains. Pops have been increased across the area to add a
slight chance of showers for the areas mentioned above. The best
chance of showers will be along the northern slopes of the
mountains. QPF amounts will be light and highly variable. Mainly
trace amounts to a few hundredths is possible tonight and into
Friday. Instability with the trough will also bring the possibilty
of night through morning drizzle tonight through Friday for the
coastal and valley areas across southern california.
Winds will be increasing across the area on Friday and Friday
night as the surface pressure gradient tightens with the
weakening cold front. A wind advisory may be needed for the
central coast and the san luis obispo county and antelope valleys
on Friday and Friday evening. Patchy blowing dust will be a threat
for the antelope valley.
Gusty sundowner winds will likely develop on Friday night along
with northerly winds through the interstate 5 corridor. Nam-wrf
solutions indicate ksba-kbfl and klax-kbfl surface pressure
gradients approaching -6 mb late Friday evening, possibly
tightening a bit more after midnight. A wind advisory may be
issued when the timing and finer details become a bit more
Northerly winds will likely linger into Saturday morning, then
diminishing some. A cold air mass will start to settle into the
great basin between Saturday and Monday setting up offshore flow
across the region.
Long term (sun-wed)
surface high pressure will develop in the great basin over the
weekend and into early next week, while a thermal trough low
pressure develops along the california coast. An offshore flow
regime will develop as a santa ana weather pattern sets up over
southern california. Wind advisory level winds look to develop
between Saturday night and Sunday, and possibly again Sunday night
and Monday. A perfect set up of offshore flow with strong ridging
aloft will likely bring record heat to much of the region on
Monday and Tuesday. Santa ana winds along with hot and dry
conditions will likely bring periods of critical fire weather
conditions to the region early next week. Many locations including
the coastal areas will be in the 90s to around 105 on Monday and
Tuesday. A mixture of headlines could be in play for Monday (and
maybe Tuesday) as heat advisories excessive heat warnings may be
needed along with wind advisories and fire weather warnings.
Offshore flow should break down for mid-to-late week next week.
Medium range models hint at the possibility of a weak weather
system approaching the region from the northwest. The best chance
of cooling looks to occur for Thursday and Friday next week.
Aviation 19 1125z...
at 1115z, the marine inversion at klax was based at 2200 feet. The
top of the inversion was 3800 feet with a temperature of 21
Overall, moderate confidence in 12z taf. Currently, ifr CIGS are
impacting the central coast with MVFR conditions across the lax
coast. Expect these clouds to dissipate later this morning with
vfr conditions for all areas this afternoon. For tonight, weak
front will sweep across the area, generating widespread MVFR cigs
across the coasts and valleys with some light showers north of
point conception. Confidence in timing of development of MVFR cigs
tonight is low.
Klax... Moderate confidence in 12z taf. MVFR CIGS may dissipate as
early as 14z. For tonight, high confidence in return of MVFR cigs,
but low confidence in timing (+ - 3 hours of current 04z|
Kbur... Moderate confidence in 12z taf. High confidence in return
of MVFR CIGS tonight, but low confidence in timing (+ - 3 hours of
current 06z forecast).
Marine 19 145 am...
for the outer waters, high confidence in current forecast. Small
craft advisory (sca) level winds will continue through Sunday and
possibly into Monday. There is a 50% chance of gale force winds
Friday afternoon through Friday night.
For the inner waters, moderate confidence current forecast. For
the waters north of point sal, there is a 20% chance of SCA level
winds this afternoon evening then a 60% chance of SCA level wind
each afternoon evening from Friday through Sunday. For the waters
south of point conception, SCA level winds are likely from this
afternoon through Friday night, especially across western sections
of the southern inner waters.
A large storm off western canada will generate 40 foot seas in
that area. This will produce a large long-period NW swell, moving
into our waters by Friday. Seas up to 15 feet are likely, with 20
foot seas possible across the outer and northern waters. There
will likely be dangerous breaking waves on the central coast
through the weekend with dangerous conditions in near harbors.
South of point conception... The westerly swell will approach high
Beaches 19 145 am...
central coast... A significant storm system in the gulf of mexico
has caused large swells to develop. These large northwest swells
will approach the central coast by Friday morning. A high surf
advisory has been issued valid for the central coast Friday
morning through Sunday morning. Surf will quickly rise to around
10 to 12 feet initially Friday mid morning. By Friday evening
through early Saturday, surf should increase to between 14 and 20
feet. Surf will then begin to lower through Saturday afternoon
into Sunday morning, but remain above 10 feet. Some impacts from
these large and powerful waves and strong currents would be the
risk of ocean drowning. Also sneaker waves can suddenly overrun
previously dry beaches and jetties. With surf approaching 20 feet,
some low lying beach parking lots, harbor walkways and
campgrounds could see local coastal flooding during the peak of
the highest surf.
South of point conception...
a fairly significant long period south swell will continue to
move across coastal waters through this afternoon and evening,
bringing elevated surf between 3 and 6 feet for south facing
beaches. However, gusty west winds are forecast to develop across
the ventura coast and the short period wind waves could pile up to
the surf zone causing local sets to 7 feet this afternoon and
evening. There is high confidence of strong rip currents during
this period. A beach hazards statement remains in effect through
The large northwest swell forecast to bring very large surf to the
central coast should filter some of the energy into the southern
california bight allowing for higher surf potential by this
weekend. Confidence is high at least another beach hazards
statement will be needed or possibly a high surf advisory if surf
is expected to be higher. Will continue to monitor the situation.
Lox watches warnings advisories
Ca... High surf advisory in effect from 6 am Friday to noon pdt
Sunday for zones 34-35. (see laxcfwlox).
Beach hazards statement in effect through this evening for
zones 40-41. (see laxcfwlox).
Pz... Small craft advisory in effect from 3 pm this afternoon to 3
am pdt Friday for zones 650-655. (see laxmwwlox).
Gale watch in effect from Friday afternoon through late
Friday night for zones 670-673-676. (see laxmwwlox).
Small craft advisory in effect until 3 pm pdt Friday for
zones 673-676. (see laxmwwlox).
Hazard potential outlook (sat-wed)
hot temperatures and elevated fire weather conditions are
expected Sunday into early next week as another santa ana wind
event develops. Record heat is possible for Monday and Tuesday.
High surf and strong rip currents will linger along central coast

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.
