What forecasters said that day

The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Anchorage, AK wrote its last area forecast discussion before this gale warning went out at Sep 2, 4:17 AM AKDT, 11 hours 44 minutes earlier.

Area forecast discussion, Sep 2, 4:17 AM AKDT, 11 hours 44 minutes before

Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
417 AM AKDT Sat Sep 2 2017

.ANALYSIS AND UPPER LEVELS...
The two major weather features impacting the area include an upper
level low centered along the west coast of Alaska and a second
upper low over the south central Bering digging rapidly southeast.
Troughs rotating around the west coast upper low have been
bringing scattered to numerous showers to southern Alaska. A
surface low south of the eastern Aleutians along 50N is rapidly
deepening along the left exit region of a powerful jet stream
pushing east. As the low deepens, ridging over the eastern Gulf is
strengthening.

&&

.MODEL DISCUSSION...
Model agreement continues to improve regarding the rapidly
deepening low south of the eastern Aleutians and Alaska Peninsula
with a strong front lifting north into the Gulf. Models still do
vary regarding the development and position of an atmospheric
river and strong southerly jet Monday and Tuesday pointed at
either the northern or eastern Gulf Coast regions. In all the
scenarios, heavy rain will impact coastal areas, the uncertainty
is with regards to the position and duration of the heaviest core
of precipitation and whether it stay pointed at one main location
or migrates back and forth along the coast.

&&

.AVIATION...
PANC...VFR conditions will persist with a few isolated showers
occasionally in the vicinity. With unstable low levels and favorable
up Inlet flow, expect southeasterly gusty at times winds to
persist through much of the day before cutting off later this
evening as flow shifts to more down Inlet northeasterly out ahead
of the deep low forming south of the Alaska Peninsula.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...
The main focus for the weekend continues to be a developing storm
center heading toward the Alaska Peninsula and the leading front
moving north across the Gulf of Alaska. The punch will be twofold,
strong winds with/ahead of advancing front and moderate to heavy
rainfall potential along coastal locations. Winds will increase
across the western Gulf marine zones today reaching gales force
late this evening. As the front continues a northward track, it
will bring gale to storm force winds to many of the northern and
western Gulf marine zones on Sunday. Pressure gradients across
inland areas will increase some today giving rise to brisk/strong
gap flows in favored locals. Except for the Copper River Basin,
gap flows will continue and may increase some into Sunday.

Steady rain will move into Kodiak Island today with the onset of
southeasterly flow. The heavier rainfall potential however will
not occur until the front gets closer on Sunday. At that time
some moderate rainfall can be expected which will eventually
spread to the eastern Kenai Peninsula and North Gulf Coast Sunday
evening/night.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Scattered to numerous showers will continue across Southwest
Alaska today as an upper level low over Norton Sound spins in
place. This area of low pressure is providing some synoptic scale
lift and is accompanied by fairly cold 850 mb and 500 mb temps
which is helping to create some mid-level instability. In the mean
time, an area of low pressure south of Dutch Harbor will quickly
intensify today and allow for 35 to 50 kt winds on the south side
of the Alaska Peninsula starting tonight. This potent front will
quickly shift east into the Gulf of Alaska Sunday afternoon/evening
but not before bringing moderate and heavy rains to the Alaska
Peninsula and Bristol Bay area. Rainfall amounts of 1 to 2 inches
will be fairly common across upslope locations along the Alaska
and Aleutian Ranges while downslope locations such as King Salmon
and Igiugig will see less than a quarter of an inch of rainfall.
Strong winds (35 to 50 mpg with gusts upwards of 65 mph) will blow
through Kamishak Bay and through Lake Clark as the front becomes
favorably oriented on Sunday. Winds and rain will diminish Sunday
night into Monday as the front moves into the Gulf of Alaska.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
A rapidly developing area of low pressure on the south side of
the Aleutian Islands and Alaska Peninsula will bring rainfall to
the eastern Aleutians through a good portion of the weekend. In
addition, strong winds upwards to 45 kts will be seen on the
Pacific side of the eastern Aleutians as the developing low skirts
across the region tonight and Sunday. Winds will diminish Sunday
night into Monday morning as the low tracks eastward. High
pressure will build across the western Bering Sea starting tonight
and build eastward as the low pressure system exits the region.
This should help usher in the return of patchy fog as moisture
gets trapped under a stout subsidence inversion.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The remnants of the storm force low from this upcoming weekend
will remain parked just south over the Eastern Aleutians on Monday
through Tuesday afternoon. The models have struggled with this
system with the NAM being the outlier in pushing this system
farther north into the Eastern Aleutians. The GFS was the
preferred model of choice with keeping the aforementioned synoptic
system farther south of the Chain. The key feature is the
atmospheric river that will develop resulting from this system as
it coincides with the strong 130 knot southerly jet streak
located over the Gulf of Alaska as it streams northward through
the Southcentral Region. This provides abundant moisture which
will stream northward resulting in potential heavy rainfall issues
to occur along the northern coastal communities from Cordova
eastward to Yakutat during the early part of next week. Therefore,
a Flood Watch has been issued for the Southeast Prince William
Sound, and Cordova from Monday morning through late Tuesday night.
While the Anchorage Bowl looks to remain downsloped resulting in
drier conditions through Thursday, but there maybe a few isolated
showers making it over the mountains with continued cooler
temperatures with cloudy skies through the midweek. Meanwhile,
the remnants of Typhoon Sanvu approaches the Western Aleutians by
Monday morning. The models are struggling with the
timing/placement of this synoptic system. By Wednesday afternoon
this low pressure system looks to be located over the Central
Aleutians near Atka before crossing over into the North Pacific
Ocean by early Thursday morning. This will bring widespread gusty
winds accompanied by stratus/rain with the Bering/Aleutians to be
under the influence of strong gusty northeasterly to northerly
winds as it tracks eastward through the midweek.
