Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
150 PM AKDT Tue Apr 1 2025

.SHORT TERM...The blocking pattern continues for SE AK through the
short term period. With that in mind, made very minimal changes to
the forecast and left most of the going forecast the same as is.
The northerly gradient that has been in place is expected to
weaken and winds will continue to weaken. Otherwise, mostly clear
skies and warm daytime temperatures will continue.

.LONG TERM...Dry conditions remain until Friday. Winds have decreased to
southerly light breezes for the majority of the panhandle preceding
the gale force front expected to reach us Friday night. Temperatures
continue to rise slowly through the week, with the majority of the
panhandle expected to see highs near or above 50 degrees going into
the weekend.

The deep low forming in the gulf is currently moving northeast with
models dropping as low as 975mb as the front reaches the outer
coast. This front will be accompanied by strong gales and sea
heights possibly exceeding 18 ft off the coast in the eastern gulf.
This system is expected to bring elevated winds to the inner
channels, with the potential for gales near channel entrances.
Precipitation associated with this system will impact the panhandle
through Saturday peaking overnight into Sunday. The northern and
central coastal regions will experience the onset first, as well as
the highest accumulated amounts as the front moves eastward. Yakutat
is expected to receive the most precipitation with 2-3 inches
through the weekend. The majority of impacts will occur Saturday
afternoon, and the active pattern is expected to continue through
the weekend.

.AVIATION.../Until 00Z Thursday/..CIG & VIS conditions will remain
within the VFR flight category, & generally benign SFC winds are
in store for Southeast Alaska through the TAF period. The only
exception will be PAGY, which will see some relatively gusty
southerly winds up to between 15 & 20 kts into this evening before
becoming light & the gusts picking-up, once again, tomorrow
afternoon. LLWS values will remain benign through the period.

&&

.MARINE...With the weakening pressure gradient, Inner Channel
winds should decrease in speed this evening and into the overnight
hours. Marine winds and waves are expected to remain on the quiet
side until the end of the week when a gale force front is expected
to move into the Gulf by Friday. Seas are expected to increase
along the outer coast with this front with peaks near 20ft along
the outer coast Friday night before winds decrease again.
