Discussion
Active weather in the bering sea and along the west coast as one
storm winds down and pushes north into the southern chukchi sea
and the next storm pushes into st lawrence island, the seward
peninsula, norton sound and the lower yk delta today. Warm
temperatures across the region will cause rain to mix in at times,
particularly across lower elevations. Warm air will spread north
to the north slope, with much of the state expecting mid april-
like temperatures throughout the week.

Aloft at 500 hpa...

a shortwave extends from near fairbanks northwest to point hope
and will continue to move to the north and east today as an upper
level ridge builds north and east out of the eastern bering sea
into the west coast and western interior this afternoon and will
build over the central interior Tuesday and the eastern interior
Tuesday night. As the upper level ridge builds over the central
and eastern interior the strong longwave over the bering sea will
continue to deepen. The upper level ridge will begin to retreat
to the south to be centered over yakutat on Wednesday and will
allow southwest flow aloft over much of western alaska and the
northern interior which will continue to see storm systems moving
northeast out of the bering sea. The upper level ridge over the
central and eastern interior will produce very warm temperatures
and minimal precipitation especially south and east of fairbanks
through the end of the week. A weak front pushes east out of the
western interior into the central interior on Thursday night and
Friday and will bring an increase in clouds and a chance of
precipitation to the central interior.

On the surface...

a front wrapping around a 950 mb low over the central bering sea
is pushing onto the west coast with strong winds, snow and rain
from the lower yk delta to norton sound, st lawrence island and
and will push into the bering strait this afternoon. In the warmer
section of the storm over the lower yk delta and norton sound
expect snow to rapidly change over to rain at lower elevations and
a rain snow mix at higher elevations. Strong wind headlines have
been issued for these areas as reduced visibility in blowing snow
is not expected to by widespread. On the seward peninsula and on
st lawrence island the rain will be later to mix with the snow and
will likely accumulate before mixing with rain, especially west
and north of nome. Winter weather advisories remain in effect for
these areas. Visibility should improve as rain mixes in this
afternoon, however winds are expected to remain strong through
Tuesday.

The strong winds continue to move up the coast today and will
impact kotzebue sound this afternoon. Rain mixing with the snow is
expected to limit blowing snow and keep visibilities above winter
weather advisory criteria. Favored strong winds headlines in
these areas.

Minimal rain is expected to mix with the snow in the brooks range
where 5 to 10 inches of wet heavy snow is expected to fall. Winter
storm warnings remain in effect for these areas.

In the northern interior rain will be later to mix, especially
over the dalton highway summits and over atigun pass. Several
inches of snow are expected to fall in these areas before changing
to rain in the lower elevations. Precipitation type is expected to
remain snow over atigun pass. Winter weather advisories have been
issued for these areas.

The front from yesterdays storm that is currently moving into the
southern chukchi sea continues to weaken as it moves into the
central interior and is currently just northwest of fairbanks.

Light precipitation is accompanying the front with a mix of rain
and snow. There is a slight chance that the precipitation could
begin as freezing rain over the central interior this morning
before changing to rain this afternoon. Winds continue to mix the
atmosphere and keep surface temperatures just above freezing. The
heaviest and most persistent precipitation is expected to remain
north and west of fairbanks.

Models...

the 00z model suite initialized well against the 00z surface
analysis and verified well against the 06z surface analysis. Model
spread is minimal in both the short term as well as the mid range
and remains very reasonable into the long range.

Coastal hazard potential... Strong and persistent winds
associated with the 950 mb low pressure system in the bering sea
are expected to shift from a shorter southeast fetch to a much
longer south to southwest fetch today as the strong front wrapping
around the low pushes north and east over the west coast.

Persistent southerly gale force winds are expected to continue
into Tuesday and will produce elevated water levels along south
and west facing shorelines. Strong winds ahead of the front and
behind the front will help break up weaker sea ice and help push
the ice on shore with the elevated water levels and rough surf
expected. At this time water levels of 2 to 4 feet above normal
high tide levels are expected over the coastal areas of the lower
yk delta, the southern shore of st lawrence island as well as most
of the coastline of norton sound. High surf advisories have been
issued for these areas. Ice and other debris will be pushed up to
the top of the beach. Residents are encouraged to move property
away from the shore.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
