.KEY MESSAGES...
Central and Eastern Interior...
- Weather remains fairly quiet through the weekend.

- Low level clouds in the Interior clear through the day,
  temperatures will drop into the single digits for many spots
  tonight. Some of the coldest locations may be below zero.

- The next chance for precipitation will be Sunday afternoon
  with a mix of light rain and snow showers.

- A period heavier rain and snow possible Monday.

West Coast and Western Interior...
- A strong low in the Bering Sea will bring gusty
  south/southeast wind and heavy snow/rain. Blizzard conditions
  expected in the Seward Peninsula midday Friday. All snow
  below 1500ft elevation changes to rain Friday night.

- Water levels are expected to rise with this storm across the
  West Coast, the highest impacts look to be in Hooper Bay.
  There will be more of an explanation in the Coastal Hazard
  section below as well as on our website weather.gov/afg.

- Snow is likely in the Western Interior on Saturday with a few
  inches likely in the Yukon Valley and several inches in the
  Koyukuk and Kobuk Valleys. This also changes to mostly rain by
  Sunday.

- Another low arrives Sunday into Monday with southwest wind,
  weaker than this current storm, another round of heavy
  precipitation and coastal concerns.

North Slope and Brooks Range...

.SYNOPSIS...
The weather is mostly quiet in the Interior through Saturday,
but the West Coast is very active with a series of storms
expected over the next several days. There will be a whirlwind
of weather including strong wind, heavy snow, rain and coastal
impacts. This pattern looks to persist into next week keeping
the weather impactful, especially over the West Coast.

&&

.SHORT TERM /THROUGH SUNDAY NIGHT/...
The pattern moving forward will consist of a trough over the
Bering and ridging over the Interior. This will allow for a
storm track from the Bering Sea to the Chukchi sea through early
next week. The main feature we are monitoring through Sunday
morning is a low currently in the Western Bering Sea. This looks
to bring a strong front with an abundance of moisture and warm
air. In terms of precipitation, we expect it to begin as snow,
heavy at times on the West Coast tomorrow. It will mix with and
change over to snow by Saturday morning. During the snow, winds
will be peaking with gusts upwards of 50 to 70 mph leading to
areas of lowered visibility, especially in the Seward Peninsula
Friday midday into the afternoon. The Western Interior will also
see snow as the precipitation runs into colder air over the
Interior. The snow may be heavy at times on Saturday with a few
inches expected in the Yukon Valley and several inches in the
higher terrain.

Surface temperatures across Northern Alaska will be well above
normal as 850mb temperatures soar to near or above 0C this
weekend. This will support most of the area getting near or
above freezing with low to mid 40s in the warmest spots of the
Interior. This also means rain is a concern. There has been snow
across Northern Alaska this past week, and as numerous fronts
move through, we are seeing heavy rain likely along the West
Coast, Western Interior and Central Interior this weekend into
next week. Rain on top of snow can lead to wet/slushy surfaces
freezing overnight as temperatures drop below freezing each
night.

Overall, we are expecting active weather to persist with a mixed
bag of precipitation, rounds of rain, snow and wind for much of
the area as well as coastal concerns. Please see the latest
updates on weather.gov/afg.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
An active pattern will remain established over western Alaska
as the jet stream continues to steer a series of low pressure
systems north- northeast across the Bering Sea. A low advancing
north toward the Bering Strait late Monday into Tuesday will
maintain a tight pressure gradient along the West Coast,
producing strong southwest winds along with coastal flooding
concerns. Warm air advection will support rain at lower
elevations, while 850 mb temperatures remain cold enough to
bring snow to higher elevations.

As the front pushes eastward into mid-week, another low moving
through the eastern Bering Sea will likely bring weaker effects
compared to the previous storms with regard to wind and coastal
impacts. While this moisture-laden system will send some
shortwave energy inland, resulting in showers across the Central
and Eastern Interior, the primary focus will remain over the
western third of the state. In the wake of this system, colder
air will return to northern Alaska before upper-level ridging
builds over the Interior by Wednesday night into Thursday. On
Thursday, a strong low in the western Bering Sea will tap into a
deep plume of moisture and deepen over open water, though the
ensemble spread regarding the exact strength and position of the
remains uncertain.

Coastal Hazard Potential...
A series of West Coast Storms will begin impacting the area
tomorrow. Water levels will rise and peak across the West Coast
between Friday and Saturday. Specific water levels and timing of
the highest water can be found at weather.gov/afg in the hazard
products (Coastal Flood Warning, Advisory and High Surf
Advisories). The main area of concern is Hooper Bay where we
expect complete cut-off from the community to the airstrip
Friday morning and early afternoon. Elsewhere, there will likely
be standing water in spots, especially Golovin and Teller but we
are not anticipating any significant flooding. Communities with
seawalls likely see waves crashing against it with some water
spilling over them, but not inundating structures.

Water levels will remain high through the weekend and we then
see another system moving in Sunday afternoon through Tuesday.
This will be accompanied by a long fetch of southwest winds
which should pool some water in Eastern Norton Sound as well as
other west/southwest facing coastlines. Significant erosion over
the long duration event is expected over most of the West Coast
early next week. As far as flooding, it is uncertain right now
but there is some concern by Monday afternoon and Tuesday. We
will continue to update throughout the event.
