Brisk Wind Advisory 67, NWS Anchorage, AK

Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
537 AM AKDT Mon Mar 9 2026

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...

Key Messages:

- The Cold Weather Advisory for Southern Kodiak Island remains in
effect through 10AM AKDT Monday for very cold wind chills as low as
15 below zero.

- A Wind Advisory remains in effect through 6PM Tuesday for the
Southern Kenai Mountains including the city of Seward (and
Resurrection Bay) for 25 to 35 mph winds with  50 mph gusts. Wind
chills this morning may drop to near 10  below zero and as low as 20
below zero Monday night.

Discussion:

The primary concern over the next several days will be gusty off-
shore gap flow winds in the usual areas (Copper River Delta, Valdez,
Seward, Whittier, etc) as a stout gradient remains in place over the
coast mountains. A Wind Advisory remains in effect for the eastern
Kenai (primarily Seward and Resurrection Bay) through Wednesday
morning for sustained 25 to 35 mph winds with 50 mph gusts.
Reinforcing shots of Arctic air will help to keep this gradient in
place as low pressure drifts around the Gulf of Alaska. Snow showers
have mostly wound down as of this morning with only a few isolated
locations still seeing rounds of light to moderate snow, including
the southern tip of the Kenai Peninsula, including Seldovia and Port
Graham, and the southern end of Kodiak Island. Both these areas
should see these snow bands taper off by mid to late morning as
winds shift ahead of an incoming trough; however, banding may become
established over the northern end of Kodiak Island or just to the
north near the Barren Islands. Elsewhere, pockets of of stratus in
the Anchorage and Mat-Su Boroughs may allow for a few light flurries
or light snow this morning as an upper level trough approaches from
the north. Unfortunately, the below normal temperatures will linger
throughout this week as this cold pattern continues. A Cold Weather
Advisory remains in effect through 10AM this morning (Monday) for
Southern Kodiak Island where wind chill values of -5 to -10 have
been common.

.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS

(Days 1 through 3)...

Key Messages:

 1) High pressure builds in the Bering Sea and trough persist in
the Eastern Aleutians through mid-week.

 2) Cold Weather Advisory remains for the Southwest Alaska
Mainland through mid-week.

Discussion:

 1) High pressure builds in the Bering Sea and trough persist in
the Eastern Aleutians through mid-week.

High pressure builds in the Western Aleutians through mid-week. It
will remain fairly stationary over the Western Aleutians through
this evening then shift more westward Tuesday and Wednesday. The
trough over the eastern Bering Sea area (the Pribilofs south to
the Central Aleutians) persists through mid-week. Rising
temperatures to Shemya and continued northerly winds and multiple
shortwave to the Eastern Aleutians/Alaska Peninsula through mid-
week is the result. The first of the early week shortwaves dives
southward from the Bering Strait bringing scattered snow showers
from Unalaska Bay to Nelson Lagoon this afternoon into this
evening. Overnight, the chance of snow showers moves slightly west
of Unalaska Bay as the high shifts westward. Wind gusts through
this evening in the passes remain gusty ranging from 35 to 55 mph.
After a more tranquil day Tuesday, another round of organized
snow showers move around the Bering Sea High and then southward
through the Aleutians and AK Pen Wednesday afternoon. Similar to
today, snowfall accumulations in the mid-week snow will be around
an inch though periods blowing snow and reduced visibility are
expected.

2) Cold Weather Advisory remains for the Southwest Alaska
Mainland through mid-week.

Downstream from the ridge, cold northerly flow continues to drag
Arctic air south across Southwest and into the AKPen, keeping
temperatures well below average for the next several days. A Cold
Weather Advisory continues through Wednesday in this area because
wind chills dip as low as -25 through Wednesday morning in the AK
Pen. A Cold Weather Advisory also remains in effect for the
Kuskokwim Delta, where wind chills will dip as low as -40 once
again tonight into Monday morning.

.LONG TERM FORECAST (Days 4 through 7: Thursday through
Sunday)...

Upper-level troughing centered over the northern Gulf of Alaska
will extend south into the Northern Pacific, with multiple
shortwaves rotating around the trough. High pressure persists
across the Bering Sea through Saturday afternoon when an upper
level low brings snow showers to the western mainland. Strong
northwesterly flow and cold air advection will result in gusty gap
winds and cold temperatures across the Alaskan Peninsula. A
tightening coastal pressure gradient will also create strong winds
through the gaps of the North Gulf Coast. Forecast confidence is
high that both Southwest and Southcentral Alaska will continue to
see below normal temperatures through next week.

.AVIATION...

PANC...VFR conditions and light northerly winds will persist
through much of the TAF period. Ceilings, although VFR in nature,
will hover around the 5,000 foot mark this morning, with a
scattered deck around 3,000 feet, before lifting more by late
morning. Winds may increase to 10 to 15 kts this afternoon through
this evening in association with weak cold air advection across
the area from the north.
