Marine Weather and Tides
Haines, 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.

240 pm akdt Sat jun 23 2018

Short term Vertically stacked low continues to lift slowly
north towards the southern gulf this afternoon. This has weakened
the pressure gradient sufficiently over the panhandle to allow for
mainly light winds with the exception of some thermally driven 15
to 20kt s'ly winds in taiya inlet. Marine stratocumulus deck
continues across much of the panhandle but with cloud bases
between 4 and 6 kft its been a pleasant Saturday most areas.

Weakening warm frontal feature will lift north through the
panhandle this evening. Most of the lift is in the h7 to h5 layer
so probably no more than an increase in mid level clouds with
this feature. A second, more low level frontal system will move
into the southern panhandle late tonight and fall apart as it
lifts north through the panhandle Sunday. Increasing height falls
and upper diffluence will focus most of the precip with this
system over the southern panhandle, mainly along and south of
frederick sound. A few periods of light rain or shower activity
are likely on Sunday over the north and central panhandle but
limited thermal advection and SE low level flow will greatly limit
precip amounts. Scattered showers will continue over the southern
panhandle into early Monday morning as the mid levels cool with
the approach of the mid level low.

The vertically stacked system mentioned above will weaken and
shift eastward into bc on Monday as a surface ridge builds over
the gulf. NAM hints at some easterly wave activity making its way
from the yukon into the skagway haines area during the day but
most other guidance keeps the wave activity to our north. Kept
scattered showers mentioned in the north but limited to isolated
coverage at best for much of the rest of the panhandle Monday.

Increasing onshore flow should continue the stratocumulus deck we
have seen over the past few days but overall Monday should be a
pleasant day. Increasing w'ly flow will allow for some enhanced
marine winds of 20 to 25 kts by late afternoon in cross sound,
making its way into icy strait by early evening. Brisk w'lies are
also likely near CAPE decision and possibly clarence strait Monday
afternoon. Overall models are in good agreement with the
exception of e'ly wave activity for Monday Monday night. Minimal
changes were made to the inherited forecast.

Long term Tuesday through Saturday ... An upper level low will
continue its trek as it swings inland from haida gwaii over to
british columbia Monday while a flattening ridge moves in over the
gulf. Zonal flow pattern will continue over the gulf through
Tuesday. Isolated to scattered showers are possible Monday and
Tuesday. Also watching the mid level low possibly redeveloping
over northern bc which could send an easterly wave over the inner
coastal mountains.

A surface ridge builds in over the eastern gulf Tuesday night
with surface winds over the gulf backing from westerly to
southerly into Wednesday and Thursday. The models continue to
suggest a frontal feature will slide into the central gulf
Wednesday. The front will likely shear and stall in the eastern
gulf. The upper low near the aleutians will continue to drive
weather across the gulf through later in the week, so left chance
of rain across the panhandle.

The operational models continue to follow along a similar line of
thinking as with the wpc solution. Minimal changes were made to
the forecast using a GFS ec blend for adjusting pop. Also nudged
winds on Friday towards the wpc.

Ajk watches warnings advisories
Public... None.

Marine... Small craft advisory due to seas for pkz041.

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.
