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 Mid upper troughing continues to broaden over the
gulf early this morning. 135kt upper jet streak is sliding across
the extreme SE gulf towards haida gwaii. A disturbance on the nose
of this jet will lift ne'ward across the southern panhandle this
morning and become nearly stationary across the central panhandle
this afternoon as northern stream energy tracks se'ward into the
yukon. This disturbance will spread showers back across much of
the area through the morning hours. Jet core will lift northward
this afternoon and pieces of energy will ride along it across the
southern panhandle through early tonight. This will focus the
heavier rainfall there, especially along west facing slopes. To
the north, an area of mid level deformation will exist between the
mid level energy over the yukon and the disturbance lifting up
from the south this morning. Thus, kept rain chances a bit higher
through early tonight for the icy strait lynn canal area. Some
cooler air will try to filter into the haines and klondike
highways today which may allow for some lighter accumulations of
snow in these areas.
Main upper trough kicks out to the east early Thursday as
mid upper ridging builds over the eastern gulf. Winds will turn
northerly over the inside waters, but this should be a weak
outflow event as there is more of a glancing and transient blow
of cool (not cold) air over the yukon. Skies will clear behind the
departing upper trough Thursday, but lingering low level moisture,
light winds, and subsidence under the mid level ridging will set
the stage for fog formation. Could form as early as Thursday
depending on when skies clear, especially where there is almost
zero low level flow to the south of the icy strait corridor. If
not on Thursday, then likely fairly early on Thursday night
especially over the southern panhandle. Where fog forms on
Thursday, it may have a hard time lifting due to low Sun angle
and no mixing. Elsewhere, expect a fairly nice day on Thursday
with clearing skies and seasonable temps.
Long term Friday through Monday Friday will provide the most
favorable weather pattern within the extended forecast as an upper
level ridge sits in place with its axis extending over the
eastern gulf. Through the day the next upper level through will
push northeast carrying an associated surface front northeast
through the day. Precipitation will likely remain offshore
through the evening hours Friday. Saturday will be wet and windy
with the front pushing ashore through the day. Sunday remains wet
with a second frontal band likely coming ashore. Currently the
early part of next week holds onto the wet pattern as well with a
surface low beginning to track across the gulf on Monday.
As far as precipitation is concerned, periods of heavy rain are
likely this weekend as a strong southerly transport carries warm
moist air toward the panhandle. With the air mass remaining
seasonably warm, low elevation snowfall is not expected. However,
temperatures along the klondike highway, especially closer to
white pass, continue to look like they will support snowfall
through the weekend, which could yield snowfall totals that
warrant a winter weather advisory as the event draws nearer.
Forecast confidence is high that the weekend will be wet across
southeast alaska; however, confidence in timing and placement of
features remains much lower as run to run consistency has been
poor and ensemble spread remains large. Precipitation was slowed
once again keeping Friday drier as a whole, if this trend
continues precipitation might not arrive until the later part of
Saturday for portions of the panhandle. Favored a blend of the 12z
ecmwf and 18z GFS to adjust timing of the precipitation with the
00z nbm used primarily for precipitation totals this weekend.

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.
