Marine Weather and Tides
Thorne Bay, 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.

southeast alaska forecast discussion
national weather service juneau ak
506 am akdt Wed jun 20 2018

Short term through Thursday night... A high pressure ridge
will persist across most of the panhandle through Thursday.

However the high pressure ridge will weaken the next few days.

The ridge will produce mostly clear to partly cloudy skies and
above normal temperatures for most of the panhandle today similar
to the past few days, however temperatures will be a little lower
this afternoon than they were Tuesday. Fog has developed across
the yakutat area this morning. The fog will dissipate late this
morning. Northwestern areas of the panhandle including yakutat
will remain mostly cloudy again today. Therefore afternoon
temperatures will be near seasonal normals for the northwestern
areas today.

Light to moderate winds will prevail across most inland areas
including the inner channels again today.

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. Afternoon temperatures were increased for
this afternoon.

Long term Friday through Wednesday ... As of 10 pm Tuesday,
the long term forecast's primary impact will be a surface low
pressure system that forms as an upper level low pushes northeast
over the northern pacific. This low looks to arrive in the
southeastern gulf early Sunday morning. Precipitation associated
with the low will begin over the southern panhandle first and
spread northward through the day. The low tracks toward the dixon
entrance on Sunday and pushes east of the panhandle by early
Monday; however, precipitation may persist through the early part
of the week.

Outside of the low this weekend, Friday and Saturday will carry
some showers over the panhandle. Greatest shower activity is
expected along the coast mountain range Friday; however, some
enhancement could occur along the outer coast and southern
panhandle Saturday as the low begins to approach and some upper
level shortwaves pass over the area. Winds as a whole remain below
small craft levels with the exception of northern lynn canal
Friday afternoon where a combination of a tighter pressure
gradient and thermal drive may push wind speeds up to 25 kts.

Temperatures moderate with highs between the upper 50s and low 60s
through the extended forecast.

Not many changes to the extended forecast were made tonight as the
surface low was well represented by the inherited forecast. Pops
were increased along the outer coast and over the southern
panhandle late Saturday and early Sunday as the low pushes
ashore. Over the northern panhandle, there is still a fair amount
of discrepancy in how far north the precipitation associated with
the low will spread so a chance of rain has been carried forward.

The ECMWF was favored to adjust the track and timing of the low
on Sunday. Behind the low there is still large variation between
models on whether a ridge builds over the gulf or another trough
moves into the area early next week.

Ajk watches warnings advisories
Public... None.

Marine... Small craft advisory due to seas for pkz022-041-042.

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.
