Synopsis for the far southern california coast.. West northwest winds will strengthen this evening into Monday. Isolated showers and Thunderstorms may affect the coastal waters this evening. A brief lull between storm systems late Monday into early Tuesday will allow for winds to weaken slightly. However, the break will be short-lived as the second system arrives Tuesday afternoon into Wednesday, generating gusty northwest winds that may approach gale force at times, particularly over the outer waters. Combined seas will also be high, 10-14 ft, during this period. Winds and seas will then diminish Thursday into Friday as high pressure builds over the region.

Synopsis
An unseasonably cold storm will move across socal through early
Monday morning, with periods of showers and possible
thunderstorms. Wintery weather will revisit the mountains as the
snow level falls below 6000 feet, resulting in accumulating snow
for many resort areas north of san diego county. Winds will be
strong and gusty over all of the mountains, deserts, and coastal
waters all the way through Tuesday. Continued cool Monday, with
showers ending in the morning. Some scattered light showers are
possible on Tuesday, otherwise it will be mostly dry and cool
ahead of the next round of showers and mountain snow to arrive on
Wednesday. A deep marine layer will remain in place through the
week due to a strong onshore flow pattern, with daytime
temperatures remaining well below seasonal averages.

Discussion For extreme southwestern california including
orange... San diego... Western riverside and southwestern san
bernardino counties...

this evening, satellite imagery shows an upper-level low centered
just southeast of san francisco, with a trough moving southeast
over los angeles county.

Only isolated light showers remain over the region but more
organized showers are developing with the feature moving through
l.A. County. To the northwest of that feature, colder air and
strong, moist, northwesterly flow is maintaining isolated showers
northwest of l.A. County to point conception. The best chance for
lightning will be overnight as the second, colder trough moves
across the region. Showers could be heavy at times, and help snow
levels lower a bit more compared to surrounding areas in the
mountains. Although light snow fell down to 6000 ft last overnight,
the snow level quickly rose to 7000-7500 ft by late morning. As
the second trough moves across the region later, snow levels will
likely lower down to 5500 ft with accumulations possible above
6000 ft. The stronger showers tonight could create heavy snow at
times, especially above 7000 ft. The winter weather advisory
remains in effect through early Monday morning for total snow
accumulations of 1 to 3 inches from 6000 to 7000 ft, 3 to 6 inches
above 7000 ft, and localized amounts up to 8 inches above 8000
ft. The coastal mountain slopes could see an additional inch to
inch and a half of precipitation by Monday morning, with lesser
amounts of a tenth or two as you head to the coast.

Winds have also increased since last night with strengthening
pressure gradients. The latest highest wind gust summary is on our
webpage. The wind advisory remains in effect for the desert
mountain slopes and adjacent desert areas through late Tuesday.

Westerly winds are looking even stronger late Tuesday as another
system takes aim at california. More precipitation and lower snow
levels return, with only a brief break in the precipitation and
strong winds late Monday. Multiple waves moving around the low
could create periods of precipitation Tuesday through Thursday.

Friday looks dry at this time, then wet weather could return again
for the weekend with another system moving across the region. This
pattern will keep high temperatures well below seasonal normals
for inland areas this time of year, with some areas staying 15 to
25 degrees below normal. Several areas could break their lowest
high temperature records over the past few days. Coastal
locations will only be a few degrees below normal since they are
usually cloudy and cool this time of year anyway.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
