Strong onshore flow will create gale-force wind gusts and hazardous seas over the coastal waters through this evening. The winds and swell will subside Sunday. Weak to moderate onshore flow will continue at times into Wednesday. Another storm system moving through the region could bring another round of strong winds and steep seas Thursday.

Synopsis
Breezy conditions will continue this evening in the wake of a low
pressure system moving from southern california into arizona.

There will be slow warming Sunday... With greater warming Monday
through Wednesday with high pressure. Weak offshore flow will
bring gusty northeast winds near the coastal foothills at times.

For next Thursday... Another fast moving low pressure system moving
through california will bring cool and windy conditions with a
chance of light precipitation. Then dry with a warming trend
Friday through next weekend as high pressure strengthens near the
west coast. High surf with strong rip currents will continue this
evening.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

a departing vigorous upper level trough now moving into arizona
with subsidence helping to squash out the few remaining rain and
snow showers in socal. Earlier we did have some brief heavy snow
showers in the mountains which dropped a coating of snow on some
mountain roads, causing slippery conditions for travelers. Breezy
conditions will remain early this evening and the wind advisories
will remain in effect until 6 pm. Cool airmass will remain in
place through Sunday with cold temperatures tonight and Sunday
morning with frost likely in the inland valleys.

Ridging the next several days will bring a slow but pronounced
warming trend to the area, especially west of the mountains.

Temperatures will gradually warmup to above normal levels, peaking
in the upper 70s in the valleys on Wednesday.

Another fast moving upper level trough will bring a chance for
mainly light rain and snow to the region Thursday through Thursday
evening. The moisture transport parameters are still quite
marginal with this system so pops were held in check in the chance
category. Beyond Thursday evening, another pattern of upper level
ridging will bring another warmup to the region with benign
weather through next weekend.

Aviation
202024z... Coast... Primarily p6sm vis will continue through Sunday
morning with sct-few cloud decks in the 3000-6000 ft msl layer.

Valleys coastal mountain slopes mountain ridges... Bkn-sct cloud
decks in the 3000-15000 ft msl layer over the mountains and portions
of the inland valleys (with areas of mountain obscuration) will
gradually become few-sct through 21 1500 utc with primarily p6sm vis.

Desert slopes deserts... Through 21 1500 utc, sct-few cloud decks in
the 6000-15000 ft msl layer gradually clearing with p6sm vis
expected. Westerly winds 20 to 30 kts with gusts 45 kts into the
evening creating mod-stg up down drafts over and east of the
mountains.

Marine
The san clemente basin buoy has been seeing northwest winds gusting
to 29-33 kt the past several hours with wave heights of around 12-13
feet. Northwest winds of 20-30 kts with gusts to 35 kts will likely
continue over the coastal waters this afternoon, decreasing to 20
kts with gusts 25 kts late this evening. Large wind waves on top of
an elevated swell will create combined seas of 8-14 ft this
afternoon and then gradually subsiding tonight into Sunday. A gale
warning continues through 10 pm tonight.

Another storm system may move through the region next Thursday,
possibly bringing another round of strong winds in the coastal
waters and steep seas.

Beaches
A building fresh swell from a local wind fetch will augment the
large west-northwest swell in place over the coastal waters this
morning, to drive some of the biggest surf of this event. 11 am
observations from the nearshore buoys show 9-12 foot waves at 14
seconds, and surf height observations from lifeguards and surfline
show 6-10 foot surf occurring earlier this morning. Occasional sets
of 12 to 14 feet are likely for exposed west-facing beaches in
southern san diego county into this afternoon. Elsewhere along the
southern california coast, 5 to 9 foot surf will continue into this
evening before subsiding later tonight. Strong rip currents will
accompany the high surf, resulting in dangerous swimming conditions.

A high surf advisory continues through 8 pm tonight.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

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.
