Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
304 PM AKDT Thu Aug 12 2021
.SHORT TERM...A robust atmospheric river (AR) directs an
incredible amount of moisture towards the Northern half of
Southeast Alaska over the next 24 to 36 hours. Rainfall began
falling over Yakutat Wednesday morning and has since greatly
increased in intensity with 4 to 6 inches having already fallen
in that area. The 12Z PAYA raob shows a top ten PW value with an
IVT of 2nd all- time (734 kg/m/s). Farther east, rain is falling
across the northern Panhandle, but at much more manageable rates.
All of this changes tonight, as a shortwave lunges into the
Bristol Bay region and begins to shove the AR eastward into the
northern Panhandle later this evening and tonight. Heavy rain
rates reach the eastern gulf coast and Icy Strait corridor later
this evening and then Juneau by tonight. Heaviest rain is expected
between 10 pm Thursday and 10 am Friday for much of the Northern
Panhandle.
Model indicated recurrence intervals have not been hugely
impressive, expecting rainfall totals for this AR to be around a
10 year recurrence interval. But what gives us pause is the
performance of some of the higher res models, notably the ARW over
Yakutat and the under forecasting of global and regional models
like the GFS/ECMWF/Canadian and NAM. If one examines the QPF
forecast related to the ten year return interval levels, then the
high res models collectively pick out much of the Icy Strait
Corridor including Juneau as an area to watch tonight into Friday
for potential flooding issues. Did not make big changes to the
overall QPF forecast with today's forecast package. Nudged the QPF
forecast with some of the higher res models to increase totals
slightly along western and SW facing slopes and decrease QPF
slightly across the rain shadowed areas in Upper Lynn Canal. Still
expecting many daily rainfall records to be broken for today and
tomorrow. Through Saturday morning, expect an additional 3 to 6
inches of rain to fall across the Northern Panhandle with the
highest amounts in upslope favored areas (Downtown Juneau,
Douglas, Pelican, Mendenhall Valley, along the mountains in
Sitka). Slightly lower totals in Upper Lynn Canal around 1 to 3
inches due to rain shadowing from SW flow aloft.
After coordinating with the RFC, A Flood Advisory has been issued
for Taiya River and Mendenhall River through Saturday afternoon
and the Situk River through Friday morning for rising river levels
reaching Minor Flood Stage. The threat for flooding continues
across much of the Northern Panhandle through Friday evening. The
risk for landslides still exists, especially during the peak
period of heavy rain from 10 pm Thursday through 10 am Friday.
Regarding winds, breezy conditions will continue for much of the
northern Panhandle with lighter winds dominating the south. Given
anticipated strengthening of gradients through Lynn Canal, kept wind
speeds to gale force through this evening. This goes well with
the strong wind gusts in Skagway and Haines through tonight. Gusts
of 50+ mph have already been observed in Skagway this afternoon
and should continue through the overnight hours. Expect another
enhancement of both land and marine winds early Friday morning as
another wave of low pressure pushes into the NE gulf Coast. Expect
small craft conditions to develop in much of the Central and
Northern Inner Channels, peaking late Friday morning then
diminishing Friday night. Due to such a stable atmosphere and WAA
aloft, it will be difficult for strong low level jet winds (45
kt) to mix down to the surface. Kept strong wind gusts of 40 mph
in Skagway as the gradient will remain tight up there; however do
not think other areas across the Northern Panhandle will see
winds that high Friday. Expect a wind shift from SE flow to SW
flow Friday evening as the main front pushes SE through the
region. A brief burst of stronger winds is likely for both land
and marine areas as the front passes through and winds shift
Friday evening. Expect winds to dramatically decrease late Friday
night through Saturday as the gradient and flow aloft weakens.
Overall confidence is high through the period.
.LONG TERM.../ Saturday to Thursday, as of 9 PM Wednesday /
A short wave aloft from the northern stream moves from western
Russia into the Yukon Delta and then into the northwest Gulf of
Alaska Saturday morning. This merges with the southern stream south
of the Aleutians, and the entire moderate long wave trough will
move across the panhandle Saturday evening.
There is a trailing low over the north Pacific that chases after
the out-going frontal band and moves into the British Columbia
coast. The northern edge of the moisture on this wave will be far
enough north to impact the weather of at least the southern
portion of the panhandle Saturday. Depending on any shifts in
tracks it could reach the south central panhandle.
A flat ridge over the western gulf will move slowly east across
the gulf followed by a short wave from a trough over the central
Aleutians. The trough exiting and the start of the ridge should
limit amount of shower activity for maybe 24 hours late Sunday to
Monday. The westerly flow that follows over the flat ridge into
southeast Alaska Panhandle will have rain spreading back in by
Tuesday.
Overall a continued damp weather pattern for SE Alaska, with no
large significant storms anticipated for the week.

.HYDROLOGY...With around 4.5 inches of rainfall forecasted today
in Yakutat, we will have to watch the Situk. There are signs that
our forecasted amounts are lower than what will fall today (see
above), so flooding is still a risk here. Further east, Taiya has
fallen below action stage, but we fully expect its waters to rise
past flood stage sometime tonight or Friday. Should confidence
rise, a flood advisory or warning will be issued. Juneau area
rivers, while somewhat high, have not responded as much to light
rains lately. But again, given saturated conditions, and expected
heavy rainfall rates tonight, especially in the higher elevations,
we do expect Jordan, Montana, Mendenhall Lake among others to rise
quickly toward Friday. The Salmon at Gustavus needs to be watched
tonight as well. We have less concern for the Chilkat in Haines
and rivers around Sitka, as recurrence intervals are not as
impressive in these locations. But for now, the flood watch is
justified.
