Marine Weather and Tides
Hydaburg, 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.

Short term through Tuesday night gale force occluded front
over the eastern gulf will drift E across SE ak this afternoon and
tonight. The front will likely stall just SE of the far southern
area by Tue morning. Weak low pressure waves will move N along
the front toward the northern bc coast Tue and Tue night. A gale
force low will slowly weaken over the western gulf through tue
night. Used blend of the 00z GFS and 06z NAM to handle the main
features.

Main concerns will be rainfall amounts and winds. The occluded
front has borderline atmospheric river conditions along it, which
will cause locally heavy rain in the area today. Looking like
southern slopes will see the most rainfall from this front. Still
expect an inch or two of rain for much of the area. Am concerned
about the far SE area late tonight into Tue night though as weak
low pressure waves could keep significant rain going there. Models
differ some on how far W this rain band will be, but potential is
there for 4+ inches of rain in some places over the far se
panhandle through Tue night. After the front moves through, precip
will transition to showers over most of the area later tonight and
tue. Still expect decent rises on area rivers and streams but
flooding is not expected attm. Will need to monitor the far se
streams though, depending on how far W the heavier rain band
remains with the low pressure waves.

Winds ahead of the front are in the 35-40 kt range over the gulf,
and 20-35 kt for the inner channels. Am expecting winds to
decrease after front moves through the area, but still hang around
sca levels over the gulf as weakening second wrap of front moves
in tonight. The far SE inner channels will hang onto the stronger
winds the longest with front being slow to move past them later
tonight. Kept in strong wind headlines for zones 23 and 27 for today.

Long term Wednesday through Monday as of 10 pm Sunday
a surface low will weaken over the central gulf on Wednesday. A
second low in the bering sea will push a front across the aleutian
islands and a triple point low will form in the far western gulf
Wednesday night, absorbing the remains of the first low. N gulf,
stealing the energy from the older low. This triple point low and
associated front will displace a ridge of high pressure east
across the panhandle through Friday night. The parent low to the
triple point will then move into the gulf and slowly weaken
through Monday night.

This monotone weather pattern will maintain cloudy and wet
conditions for the panhandle though much of the long range
forecast period. The second low moving in from the west will
increase the winds in the gulf to 20 kt as early as Thursday
morning through Friday. The gradient will also tighten over the
northern inner channels Friday night for a brief pulse of stronger
winds as well. After that, the winds will return to 15 kt or
less. Temperatures will remain in the mid to upper 50s during the
day and ranging in the 40s overnight.

Overall models remain in fairly good agreement. Used gfs ECMWF to
make minimal changes to the forecast through the weekend and wpc
solution Monday.

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.
