southeast alaska forecast discussion... Corrected
national weather service juneau ak
533 am akdt Sun apr 22 2018

Short term Sunday to Tuesday a strong spring weather system
will be moving its front across the gulf of alaska to the coast
Sunday. The parent low will be remaining on the west side of the
gulf near kodiak. The eastward progression of the front will be
slowed by 2 or 3 waves impulses which develop on the southern
portion of the front then move north along it, in the upper level
flow.

Expect gale force winds ahead of the front to move into the outer
coastal waters late afternoon and evening and then hang onto near
daybreak Monday. Gale to near gale force winds should develop
over the inner channels to include; clarence and chatham straits,
stephens passage, frederick and cross sounds.

Expect the rain to move across the area during the day on Sunday.

One of the waves will be moving north along 140 west to move to
south of yakutat Sunday evening, and the next approaches baranof
island early Monday, with a third one moving into the misty fjords
area Monday evening. Each of the the waves will bring with it a
slight increase in wind speeds and an increase of rainfall.

Model agreement was generally good with the Sunday to Monday
system. To increase winds over the gulf, used a blend of the gfs
and nam, a touch heavier on the GFS to adjust the winds. Pops also
got a minor increase today favoring the gfs.

Long term Tuesday through Sunday as of 10 pm Saturday
occluded front will be moving E out of the area early tue
morning. Another occluded front will move into the western gulf
tue afternoon, then reach the eastern gulf by early Wed morning.

Still some model differences later Wed into Thu on how fast this
front moves through the area. The front will be weakening as it
moves onshore. GFS was fastest moving it through, with ecmwf
slowest. Ended up using the 18z GFS to handle the system through
00z thu, then transitioned to wpc for 12z Thu onward. This made
for a smoother transition between the different sources. Further
out, models suggest more ridging will develop over the E gulf and
se ak for late week and the weekend, but they have been
inconsistent on smaller scale shortwaves that might affect the
area.

Looking like most of the rain and wind with the second front will
be over the NW half of the area Wed into early thu. It is
questionable whether any precip will get into the far SE part of
the area, so kept any pops there on the low side. Currently think
later Thu into Sat will be dry over the area with the ridging, but
model differences make it difficult to be confident in this.

There could be another system approaching the area from the sw
sun, which would increase the precip threat then.

Aviation A strong spring weather front will be affecting the
coast of southeast alaska Sunday. A strong low level jet will be
approaching the coast and spreading into the panhandle. Think that
the biggest issue will be the low level wind shear and turbulence
near the rough terrain as this jet moves into the panhandle today
and this evening. Before then, ceilings of 1500 to 3000 ft and rain
are the aviation hazards. With more rain headed into the panhandle
visibilities and ceilings will be lowering overnight.

Ajk watches warnings advisories

akz027.

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.
