Marine Weather and Tides
Excursion Inlet, AK

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.

509 am akdt Tue jun 19 2018

Short term through Wednesday night the northwestern areas of
the panhandle including yakutat will continue to have mostly
cloudy skies and rain at times through this afternoon as an
occluded frontal weakens and dissipates.

A high pressure ridge extending northward across most of the
panhandle will continue to produce mostly clear skies and above
normal temperatures for most of the panhandle today similar to
Monday. Patchy fog has formed across some coastal areas this
morning including sitka and gustavus. The fog should dissipate
later this morning. The high pressure ridge will weaken and shift
southward Wednesday. Above normal afternoon temperatures will
continue across most of the panhandle, except the northwestern
areas, Wednesday but will likely not be quite as warm Wednesday
afternoon as this afternoon.

Light to moderate winds will prevail across most inland areas
including the inner channels through Wednesday.

Changes to the forecast were minimal today as the weather systems
continue on track from previous model runs. Used the NAM nest and
gfs for any changes with the SREF and GFS used for changes to
pops. Afternoon temperatures were increased for this afternoon
and Wednesday afternoon.

Long term Thursday through Tuesday ... The long term forecast
will see precip chances increasing through the weekend. Thursday
and Friday, the high pressure ridge that has been in place over
the eastern gulf will weaken some as a couple upper level short-
waves surface trough pass through from the sw. There are still
differences in timing for these and potential showers, but most
models are converging on Thursday night through most of Friday
attm. As the trough(s) move through some of the central inside
waters will see winds shift NW to SW for a period then likely
back.

A low pressure system will approach the southern gulf from the sw
on Saturday. Models have come into better agreement on the south
track of the low, but still differ some on how quickly assoc rain
reaches the coast. At this time rain is looking most likely for
the southern panhandle later Saturday and most of Sunday. The
northern panhandle should see less rain due to offshore flow, but
will likely have a cloudy day with much cooler temperatures than
that start of the week.

The ridge in the gulf looks to re-build as the low pressure moves
east into canada. This should help to decrease the precip threat
Monday, but models are holding on to it longer along the coast
mountains. Used a blend of models to help with the timing of the
troughs and low pressure system over the weekend to find a middle
ground.

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.
