Discussion
Overall weather pattern is still active along the west coast of
alaska. Aloft at 500mb, the upper level low that was over norton
sound the previous day has moved towards bering sea south of
chukotsk peninsula and will move southwest through Tuesday. This
same low is reflected at the surface and brining strong northerly
winds across st lawrence island up to point lay today. A series
of shortwaves have impacted the central and eastern interior the
past couple days. Last night the clouds cleared enough for some
clear skies in between these shortwaves where temperatures now
reached in the greater fairbanks area below zero. However,
another shortwave will be moving northward with snow expected from
tanana eastward to eagle and and extending from arctic village to
mcgrath by tomorrow morning.

At the surface... A low over seward peninsula will move to norton
sound north of emmonak as a 979 mb low by Tuesday afternoon and
slowly shift southward along the coast to hooper bay by Wednesday
morning. This surface low will continue to bring strong northerly
winds to st lawrence island and bering strait. A strong pressure
gradient extends across the brooks range will continue to see
increased winds but not within advisory or warning criteria. The
winds over the ray mountains will also continue through tomorrow
afternoon but remain below any advisory criteria. Can see some of
the winds in the latest satellite IR imagery.

West coast and western interior... Strong northerly winds continue
across the st lawrence and bering strait with 25 to 35 mph and
gusts up to 45 mph. There was additionally some 2-4 inches of snow
with higher amounts on the bering strait coast. Savoonga starting
having reduced visibilities which could be related for fog but
imagine with the 40 mph winds it was blowing snow. Expect up to
one half mile or less at time in areas such as savoonga so
decided to issue winter weather advisory. Expect winds to slowly
diminish on Tuesday. Winter weather advisories for russian mission
through marshall northward through kotlik. Could see areas from 4
to 7 inches through this area through Tuesday. The winds will
also continue to bring high surf to the area and continued with
the high surf advisory through Tuesday along. Northeasterly winds
across point hope and CAPE lisburne is expected to gust up to 40
mph near point hope on Tuesday, expect visibilities to be reduced
to less than one miles at times.

North slope... Main concern is along the chukchi sea coast where
strong winds of 15 to 25 mph with low temperatures is causing wind
chills of 50 below zero from point lay southward. This will
continue with the strong winds through Tuesday so have kept the
wind chill advisory for this area though Tuesday afternoon. Could
potentially see it extended depending on the winds but should
slowly drop for areas west of utqiagvik.

Central and eastern interior... The fairbanks airport finally
received below zero temperatures for the first time this month
which is still unseasonably warm. The clear skies will be brief as
another shortwave is moving northward bringing snow to eastern
and central areas by tomorrow morning. Expect higher snow amounts
up to 2 inches in eagle with up to an inch of snow through
Tuesday for fairbanks area. Then Tuesday night into Wednesday
there will be an additional 2 inches across the central interior.

Winds currently across the ray mountains will slowly subside this
evening.

Coastal hazard potential days 3 and 4... High surf advisory will
continue through Tuesday as northerly winds sustained 25 to 35 mph
with gusts up to 40 mph across st lawrence and bering strait.

Winds will still continue through Wednesday as we head into day 3.

Afg watches warnings advisories

High surf advisory for akz213.

Winter weather advisory for akz213-akz214-akz215.

Heavy freezing spray warning for pkz210-pkz220-pkz225.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
