What forecasters said that day

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

NWS Juneau, AK wrote its last area forecast discussion before this small craft advisory went out at Sep 21, 5:35 AM AKDT, 1 hour 11 minutes earlier.

Area forecast discussion, Sep 21, 5:35 AM AKDT, 1 hour 11 minutes before
Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
535 AM AKDT Tue Sep 21 2021

.SHORT TERM...Surface analysis and satellite imagery show low
pressure spinning S of Cape Suckling with front pushing into the
outer coast attm. The N edge of the main moisture stream
clipping the Misty Fjords area but generally moving into W BC
this morning. Although no lightning has been detected overnight,
the 12Z PAYA sounding came in with ~8C/km mid level lapse rate
with a slight inversion at the surface, so maintained mention of
TS this morning over the NE gulf and coastal areas. Showers will
prevail for most of the panhandle through the day with a
decreasing trend beginning late afternoon/evening. Given the
continued onshore flow through Wed maintained isold-sct shra
across the region. The driest weather of the week will be brief as
precip chances begin increasing again late Wed night/early Thu
morning. Breezy winds will gradually ease today as the front
pushes through the panhandle. Models in fairly good agreement with
generally another 1-2" of precip today with some energy from the
low over the gulf moving into SW YT tonight. This will result in
an increasing S gradient across the N tonight with SCA winds
through Lynn Canal. Forecast confidence remains above average for
Wed to be the driest day this week.

.LONG TERM.../Thursday through Monday night/...The extended
period will be an active, stormy period for SE Alaska and the
surrounding waters as robust low pressure systems move through the
Gulf and into the panhandle. Cold air advection filtering into
the panhandle behind the Monday/Tuesday system will also see nippy
temperatures in some areas, and it is looking possible that parts
of the highways like White Pass may see a bit of snow Wednesday
night through Thursday morning. Thursday will see an upper level
trough displace the ridge and march across the gulf. Its surface
reflection, a strong frontal system and associated low, will bring
with it abundant wind and rain to the area. Operational models
have come into decent agreement on the gale force front entering
the panhandle on Thursday. The parent low is progged to stay over
the N Gulf through Friday before dissipating over Southcentral AK
through Saturday. This system will continue to impact the area
through at least Friday, before rain diminishes Saturday and
Sunday. There are some indications that offshore flow may become
predominant in the lower levels later on Saturday and into Sunday,
which would lead to a brief period of drier weather before
another possible system arrives late Sunday or Monday. Guidance
rapidly diverges after Monday, but it looks likely that the active
weather pattern will be set to continue.

&&

.HYDROLOGY...Area rivers and streams over the AOR all rose in
response to rainfall yesterday. Another 1-2 inches of rainfall
expected today, but more focused on the central and N panhandle.
Expect to see rises on area streams and rivers through this
afternoon in response. Flooding is still not anticipated with
today's rain. Focus then shifts to next system poised to bring an
additional 1-3 inches of precip beginning Thu.

&&

.AJK WATCHES/WARNINGS/ADVISORIES...
PUBLIC...Strong Wind until 10 AM AKDT this morning for AKZ023.
MARINE...Small Craft Advisory for PKZ012-013-022-031-041>043-051>053.
