Synopsis 18 146 pm.

A ridge of high pressure will build over the region through
Saturday bringing dry conditions, mostly clear skies, and warmer
temperatures to the region. Low pressure will skirt the area from
the north later Sunday into Monday with some clouds and cooler
temperatures. Persistent offshore winds should affect the area
through much of next week with dry weather and gradually warmer
temperatures.

Short term (tdy-mon) 18 142 pm.

Northwest flow developing across the area today before
transitioning to a weak santa ana Saturday. In the meantime still
dealing with some lingering low level moisture trapped over
southeast la county, especially up against the foothills of the
san gabriels. Moisture also continues to spill into eastern slo
county and this will likely continue into early Saturday and
generate some locally dense fog there. Northwest winds tonight
expected to remain mostly below advisory levels except for the
usual wind prone areas like above gaviota in southwest sb county.

Similar situation with the santa ana tomorrow with winds mostly
below advisory levels due to minimal upper level support. Temps
will be warming up quite a bit across coast valleys with highs in
most areas in the 70s.

Offshore flow weakens Sunday as an inside slider rides up and over
the eastern pacific ridge and down through the great basin late
Sunday into Monday. Temps for coast valleys will cool a few
degrees but either little change or slightly warmer across the
interior. Models had a little more low level moisture across
northern areas Sunday night as the tail end of a weak cold front
moves through and decided to go with a slight chance of light
showers there followed by some upslope showers near the kern
county line early Monday. An even stronger northwest north flow
will develop Sunday night due to much stronger winds aloft and
advisories may be needed for SRN sb county and the i5 corridor
area.

A cooler day Monday with highs back down into the 60s at lower
elevations and 30s 40s in the mountains. Could be some light snow
down to around 5000' Sunday night into early Monday near the
grapevine. Windy again Monday night but more of a north northeast
direction as we transition to a santa ana Tuesday.

Long term (tue-fri) 18 146 pm.

The santa ana developing Tuesday is expected have stronger winds
aloft and more cold air with it resulting in a better chance for
advisory level northeast winds across ventura and la counties.

Temps will warm up from Monday but not as much as usual with santa
ana's because of the cold air associated with the trough.

Additional warming expected wed-fri as ridging develops and
offshore gradients continue. Winds expected to be below advisory
levels after Tuesday with highs warming back up into the 70s at
lower elevations. Chilly overnight lows expected in wind protected
locations.

Aviation 18 1911z.

At 18z at klax... There was 3000 foot deep moist layer, but no
inversion.

Low confidence on los angeles county airports, with a potential
for sporadic MVFR vis or cig at any time through 02z. Kprb should
improve toVFR sometime between 19-22z. For tonight, there is a
60 percent chance of lifr conditions at kprb ksmx, and a 30
percent chance at kwjf. There is a 40 percent chance of ifr
conditions at klgb, and a 20 percent chance at klax ksmo ksbp.

Klax... Low confidence through 02z. Sporadic MVFR hz or CIGS could
form at anytime. 20 percent chance of ifr CIGS 08-16z Saturday.

Kbur... .Low confidence through 02z. Sporadic MVFR hz or CIGS could
form at anytime.

Marine 18 131 pm.

Moderate confidence in the large seas subsiding to under 10 feet
everywhere by Saturday morning. 70 percent chance for low end
small craft advisory (sca) winds near 25 kt from point conception
to san nicolas island. North to northeast winds are expected
south of ventura on Saturday including the santa monica bay, but
not expecting winds to exceed 15 kt.

Moderate confidence in widespread SCA nw-w winds of at least 20
to 30 kt late Sunday afternoon through Monday night, including the
inner waters. There is a 40 percent chance of reaching gale force
over the outer waters, and a 20 percent chance over the inner
waters. NE winds expected quickly on Tuesday, with a 20 percent
chance of low-end SCA south of ventura.

Beaches 18 132 pm.

Large and potentially damaging surf peaked last night and has
begun to subside. While the surf remains large, reports of surf
exceeding warning criteria are isolated to ventura harbor and
north manhattan beach. Decided to downgrade the high surf
warnings to high surf advisories and stretched them out to
Saturday morning. Regardless of the downgrade, this swell event
is still very dangerous to the immediate coast. People need to
stay off rock jetties and out of the water. Boaters need to be
careful not to drift too close to shore.

We did get a few reports of coastal flooding. Bike paths were
flooded with sea water in playa del rey and dockweiler of los
angeles county. Parking lots were flooded at zuma beach and got
close at cayucos. Tides are expected to increase by about 5 inches
by Saturday morning, but surf will lower by 4 to 6 feet compared
to this morning. As a result, minor coastal flooding is possible
but not to the extent of this morning. Canceled the coastal flood
advisory, but will continue to mention minor impacts.

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.
