Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Short term through Friday night current satellite imagery
Thursday morning shows weak upper ridge shifting over british
columbia and a broad area of low pressure south of haida gwaii.
Weak upper trough digs into the yukon through Thursday night as an
upper ridge builds over the npac off the pacific NW coast. A few
weak shortwaves will move north across the eastern gulf and
southeast alaska. Surface analysis shows an area of high pressure
persisting across NW canada through Thursday night before
shifting eastward Friday. Complex area of surface low pressure
moves into the southern gulf early Friday and ejects a weakening
occluded front northward over the panhandle through late Friday.
Fog continues to persist in a few areas Thursday morning,
including petersburg, kake, and gustavus. The dense fog advisory
was allowed to expire early this morning as visibility has risen
generally. Cooler temperatures in the 850-925 mb layer have
allowed the inversion to dissipate, and with cloud cover expected
to increase across the southern panhandle tonight, not
anticipating dense fog to redevelop Thursday night thru Friday
Outflow winds will continue across parts of the northern inner
channels Thursday through Friday, with the strongest winds
expected through lynn canal and out of interior passes this
morning through Thursday night. Northerly winds are expected to
reach gale force this morning, before diminishing early Friday.
Strong winds are also anticipated to occur in the skagway area
during this same timeframe.
Dry weather expected to continue across the panhandle Thursday,
with only bands of high to mid-level clouds as the shortwaves move
across. Then increasing chances of precipitation from south to
north Friday, with rain more likely across the southern half, and
chance of snow flurries moving into the northern panhandle late
Friday. Forecast confidence is average.
Long term Saturday through Wednesday, as of 10 pm Wednesday
while the weekend continues to draw nearer, the forecast continues|
to remain uncertain. Extreme shifts in Saturday's low track
continue with each new model guidance provided. Synoptically,
Saturday begins with 3 upper level low pressure systems
interacting with each other, the strongest of which sits the
border between northern alaska and the northern yukon, and it
will likely act to direct weather systems further south from
southeast alaska's perspective. The other two upper lows remain
over the the northern pacific. This leaves multiple surface lows
and fronts scattered over the southern gulf and northern pacific
as well as a forecast situation.
Precipitation for Saturday has trended further south. This
drastically lowered the snow amounts over the northern panhandle
as a whole. Additionally with the more southern low track now
favored in the forecast gales are no longer expected over the
Sunday the surface front driven by the more western upper low
over the northern pacific looks to come ashore. Ultimately, wind
will not be very impactful Sunday; however, snow potential will
still exist briefly for the northern panhandle before the warmup
likely begins. Monday through midweek, continues to look quite
wet and active; however, this will also mark a shift into a much
warmer weather pattern with highs pushing well above freezing by
the middle of the week for the vast majority of the panhandle.
Forecast confidence is below average for the weekend and
adjustments are likely. Ensemble means and the nbm continue to act
as the primary guidance of the extended forecast. Fortunately,
next week shows much clearer signatures allowing for higher
confidence Monday into mid- week.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
