Marine Weather and Tides
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.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Synopsis 20 315 pm.
A strong storm moving into the region will bring waves of significant
precipitation to the region through early Friday. This could result
in debris flows at all recent burn areas as well as periods of urban
and small stream flooding. The heaviest rainfall and a chance of
isolated thunderstorms will come Wednesday afternoon through Thursday.
Notable snowfall will remain above 9000 feet.
Short term (tdy-fri) 20 131 pm.
Big plume of subtropical moisture still on track to bring rain to
the area through Thursday night. The question remains where and
when will the heaviest precip occur and will there be convection
with it. Currently radars show some light precip just off the
coast that will move in later this afternoon and evening. However,
later tonight the moisture plume will shift south and will
interact with the topography as winds shift to the south southwest
to increase rain rates. Both the 12z NAM and GFS show the first
strong burst of rain coming early Wednesday with the focus on srn
sb county and western ventura county. This also jives well with
some higher res models. Still don't have a lot confidence in the
precise location and rates mainly because models have been
bouncing around a lot from run to run, but they might be keying
on some increase in instability to assist with the rainfall
intensity. Didn't see enough in the forecast soundings to justify
thunderstorms near the mainland tomorrow morning but it's not a
zero chance either. If the conditions pan out as models are
showing rainfall rates will peak in the .50-.75" hr range and with
thunderstorms that could go as high as an inch per hour.
Across la county precip expected to remain fairly light and
perhaps in some far eastern areas not even measurable through
Models showing the next burst of precip coming late Wednesday
night into Thursday as the moisture starts to interact with a cold
front coming through. This might provide the best environment for
thunderstorms, though again stability parameters are pretty
marginal. CAPE values remain low, though li's do go briefly
negative with the frontal passage Thursday morning. This is also
when la county will likely see their heaviest rain as the
moisture plume shifts south. Rainfall rates should be similar to
what occurs late tonight and early Tuesday.
Rain will taper off Thursday evening with dry weather expected
No snow expected as snow levels will be above 8000' for the
duration of this event.
Long term (sat-tue) 20 123 pm.
Expecting dry but cool conditions Saturday with some breezy
northwest winds possible. A trough will pass north of the area
Saturday night and there is a little moisture with it but mainly
north of slo county. May have to introduce some slight chance pops
north of pt conception as we get closer but for now it looks too
weak to generate any precip in our area. Gradients will start to
turn offshore early next week, though models differing on the
strength and amount of upper support. Pretty high confidence in a
dry forecast but low confidence on possible santa ana winds and
how much warm up we'll see.
Aviation 21 0014z.
At 2330z, there was a surface-based inversion at klax. The top of
the inversion was 1400 feet with a temperature of 17 degrees
Moderate confidence overall in the 00z TAF package. Rain will
gradually spread south and east across TAF sites through the
period with MVFR conditions likely with steady rain by early this
evening for kprb, ksbp, ksmx and ksba, then lower to ifr for
these airfields late tonight and Wed with moderate to heavy rain.
For koxr and kcma,VFR CIGS with light rain are expected tonight
then lower to ifr Wed morning thru the afternoon with steady
moderate rain.VFR CIGS should prevail at remainder of airfields
tonight then gradually lower to MVFR and ifr thru the day on wed.
Confidence in timing of lowering flight cats is low, and could be
off + - 2 hours or more.
Klax... Moderate confidence overall in the 00z taf.VFR CIGS with
an increasing chance of rain should prevail tonight then
gradually lower to MVFR by 17z and ifr by 00z. CIGS may improve to
vfr by 03z Wed evening, but confidence in this is low. Overall
confidence in timing of lowering flight cats and changes between
flight cats is low, and could be off + - 2 hours or more.
Kbur... Moderate confidence overall in the 00z taf.VFR CIGS with
an increasing chance of rain should prevail tonight then
gradually lower to MVFR by 15z and ifr by 20z. Overall confidence
in timing of lowering flight cats is low, and could be off + - 2
hours or more.
Marine 20 101 pm.
For the outer waters, good confidence in current forecast. There
is an 80% chance of small craft advisory (sca) level southeasterly
winds today through Wednesday night. For Thursday through
Saturday, there is a 70% chance of SCA level west to northwest
For the inner waters, good confidence in current forecast. For the
waters north of point sal, there is a 70% chance of SCA level
southeasterly winds today through Wednesday evening then a 60% of
sca level northwest winds Friday Saturday. For the waters south of
point conception, there is a 40% chance of SCA level southeast
winds this evening through Wednesday evening. For Friday and
Saturday, there is a 50% chance of SCA level westerly winds.

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.
