Marine Weather and Tides
Santa Ana, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
A slow moving low pressure system moving inland through california
will maintain a deeper marine layer and stronger onshore flow into
the weekend. Into Saturday... There be some drizzle for coastal
and valley areas during nights and mornings with limited or no
afternoon clearing towards the coast. There will be periods of
stronger and gusty southwest to west winds for the mountains and
deserts from Friday afternoon into Saturday evening. For Sunday
through Tuesday... Low pressure over the western states will
weaken. There will be a warming trend away from the coast with
high temperatures for the deserts warming to around 5 degrees
above average for Monday and Tuesday. Night and morning coastal low
clouds will extend into portions of the valleys with afternoon
clearing getting closer to the coast.

Discussion For extreme southwestern california including orange...

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

Short term (today through Saturday)
A low pressure system off the california coast will move slowly
inland for tonight through Saturday. This will maintain onshore
flow... Strongest for Friday and Saturday with periods of stronger
and gusty southwest to west winds in the mountains and deserts
from Friday afternoon into Saturday evening.

The marine layer is near 4500 feet deep with aircraft soundings
showing a saturated layer from around 1500 feet to around 4500
feet. There has been some drizzle overnight with the greatest
coverage in coastal and valley areas of san diego county into
coastal orange county with widespread reports of 0.01 inch of
precipitation. This deeper marine layer will continue into
Saturday with soundings from the local workstation WRF having a
saturated layer of similar depth for each night through morning
with that layer still moist but not saturated in the afternoons.

Drizzle is expected each night through morning with patchy drizzle
possibly continuing into the early afternoon in some locations.

Limited or no clearing is expected for coastal areas.

There will be little change in high temperatures for coastal and
valley areas with high temperatures near the coast a few degrees
below average and 10 to locally 15 degrees below average for the
inland valleys. Slow cooling is expected for the mountains and
deserts.

Long term (Sunday through Wednesday)
Low pressure will weaken over the western states for Sunday
through Tuesday. The marine layer will become a little less deep
each day... Though low clouds will still extend into portions of
the inland valleys for Sunday night into Monday morning and Monday
night into Tuesday morning. There will be greater and faster
clearing towards the coast though afternoon clearing at the coast
could continue to be slow or limited.

There will be a warming trend for Sunday through Tuesday with high
temperatures for inland areas on Monday and Tuesday around 5
degree above average. A weaker low pressure system moving inland
along the west coast will bring a cooling trend beginning
Wednesday.

Aviation
240945z... Coast valleys coastal mountain slopes... Low clouds with
bases 1300 to 2500 ft msl and tops to 4000 ft msl continuing west of
the mountains this morning. Higher terrain will be obscured through
mid-morning. Clouds slowly clearing inland 16-20z, with only partial
clearing in the coastal areas. Clouds will quickly spread back
inland after 25 02z with similar bases and tops.

gusts 25-35 kt may produce localized llws with mod uddfs over the
mountain crests and into the deserts.

Marine
West northwest winds with gusts near 20 knots are possible Friday
and Saturday afternoon evening. Winds will weaken Sunday into early
next week.

Beaches
A long-period south swell of 3-4 ft 15-16 sec will continue to
produce elevated surf and hazardous swimming conditions through this
afternoon mainly in orange and northern san diego counties. Sets to
7 ft are possible. Surf will begin subsiding tonight.

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.
