Synopsis 22 1237 pm.

Dry weather is expected today before a weak storm system brings a
chance of rain to areas north of point conception late tonight.

Light showers may also affect the l.A. And ventura mountains on
Saturday. Expect dry conditions Sunday through early next week.

Another weak storm could bring showers to the region for the
middle of next week.

Short term (tdy-mon) 22 115 pm.

A pleasant though cooler than normal day across the area under
partly cloudy skies. The tail end of a storm moving into northern
california today will move through slo sb counties later tonight
into early Saturday and drop some light rain. Rain amounts
expected to range from a quarter to half inch across northwest slo
county to barely measurable across northern sb county. For
la ventura counties just some clouds, perhaps a few light showers
near the kern ventura county line but that's about it. Northwest
flow will basically eliminate any chances for rain in southern
areas. Skies will start clearing out Saturday afternoon with a
sunny and warmer day Sunday. Temps expected to climb into the
lower 70s for many coast valley locations.

On Monday the tail end of a second weather system will again brush
northern areas and possibly drop some light rain, mainly northern
slo county. Elsewhere, the combination of light offshore flow and
ridging aloft will lead to even warmer temps, with highs in the
mid to upper 70s across the la ventura valleys.

Long term (tue-fri) 22 126 pm.

Still some fairly significant model differences for the rest of
next week but minimal impacts either way. We will continue to be
at the southern fringe of systems moving across the pacific and
into northern california. Later Tuesday and Tuesday night will be
the next one to provide a chance of light precip to slo sb
counties. A secondary wave could push the rain as far south as la
county by Wednesday but pretty low confidence in that and even if
it happens amounts would be mostly under a tenth of an inch. Model
consensus is good for dry and warmer weather Thu Fri with temps
returning to normal Friday.

Aviation 23 0004z.

At 23z, there was no marine layer at klax but there were moist
inversions aloft, from 2000 to 2500 feet, and from 3700 to 4500
feet. At 4500 feet the temperature was 8 deg c.

Low to moderate confidence in 00z tafs. An approaching storm
system will bring -shra to the airports north of point conception,
along with ifr to MVFR conditions. MVFR CIGS may also affect the
coastal and valley sites further south, but timing is very low
certainty. Gusty westerly winds will affect the desert areas
through the period, strongest after 18z.

Klax and kbur... Low confidence on timing of MVFR CIGS tonight
after 06z, with a 40 percent chance that conditions remainVFR.

Increasing confidence inVFR conditions after 18z Saturday.

Marine 22 114 pm.

West to northwest winds will increase this afternoon and evening.

There is a 70 percent chance of low end small craft advisory (sca)
conditions south of point conception, especially beyond 20 miles
from the coast. These winds will also generate choppy seas nearly
everywhere on top of the longer period west to northwest swell.

The winds will become more northwest, with the focus shifting to
the usual area from the central coast to san nicolas island. 70
percent chance of SCA winds for that focus area, and a 90 percent
chance of 10+ foot SCA swells. There is a 40 percent chance for
sca winds over the west central sba channel as well. High
confidence in winds weakening significantly on Sunday and under
sca everywhere, although and SCA will likely continue for the
central coast due to the large swell.

Beaches 22 136 pm.

A long 18 second period west to northwest swell will fill in the
coastal waters today, and peak in height later on Saturday. While
periods will drop to about 15 seconds during the Saturday peak,
the combination of size and period will be enough to generate high
surf on the central coast between 8 and 14 feet. Surf will also
build along the west facing beaches of the southern california
coasts as well, especially on the ventura county coast where waves
should peak in the 5 to 8 feet range. There is a chance that some
spots on the los angeles county coast will also see waves of 7
feet. As a result, will likely be issuing a high surf advisory for
these areas. The isolated west facing beaches of santa barbara
county, like rincon, could also see waves near 7 feet, but will do
not plan on issuing an advisory due to the highly localized
nature. The swell and surf should gradually subside on Sunday.

Waves like this pose a serious risk to anyone that enters the
ocean. Strong and deadly rip currents will be happening. Please
emphasize the special risk of anyone on the rock jetties, as there
is a long history of fatalities from people that go on the rocks
and tide pools during such events.

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.
