Discussion
Overall weather pattern is still active aloft at 500 mb with
upper level low meandering around norton sound by kivalina by this
afternoon and slowly shifting west toward chukotsk peninsula by
Monday morning. This same low is reflected at the surface and
causing the strong winds across the st lawrence island and bering
strait that will increase winds along point hope and cape
lisburne on Monday. A series of shortwaves are moving northward
across central interior with the next round of snow currently
occurring per the pedro dome radar reflectivity as this shortwave
moves northward overnight tonight. The next shortwave will move
northward across eastern interior Monday afternoon and evening.

At the surface... A 984 mb low over eastern norton sound will
remain nearly stationary as it will be near shishmaref this
afternoon and then persist through Monday evening. High pressure
in the high arctic will start to build staring Monday afternoon
and persist through Wednesday moving slowly east at 1007mb. A
pressure gradient extending across the brooks range will begin to
tighten on Monday afternoon and will see increase in winds. Even
across the ray mountains with increased winds across livengood to
coldfoot on Monday afternoon.

West coast and western interior... A vertically stacked low
pressure system over the eastern norton sound will move to over
the southern chukchi sea tonight and then over to the chukotsk
peninsula on Monday. This system is causing the strong northerly
winds of 25 to 35 mph with gusts up to 40 mph across st lawrence
island and bering strait. These winds will then start to extend up
to point hope and CAPE lisburne through Monday evening. Expect
snow showers to continue with this features as well with the
combinations of winds and snow brining blowing snow and drifting
snow. This will also reduce visibilities across the area,
particularly across st lawrence island and bering strait. Could
visibilities reduced to 1 mile or less at times. The winds will
also continue to bring high surf to the area and continued with
the high surf advisory through Tuesday along. Winds will slowly
diminish on Tuesday. Northeasterly winds across point hope and
cape lisburne is expected to gust up to 45 mph near point hope
through Tuesday.

North slope... Snow will spread northward extending from point lay
through prudhoe bay to kaktovik overnight tonight and diminishing
by mid morning Monday from west to east. Expecting additional
snow amounts of 1 inch overnight with reduced visibility in the
snow and fog. North to northeast winds will increase to 15 to 30
mph primarily in coastal areas with the strongest west of
utqiagvik.

Central and eastern interior... As the shortwave moves northward
another round of snow accompanies it across central interior. Some
areas in far eastern interior have warmer temperatures such as
eagle with 31f at 2pm akst which is very unusual. However, there
is no precipitation in far eastern interior expected in the late
afternoon. However as this system pushes preciptiation eastward
overnight the temperatures will drop along with increasing
precipitation. Thus expect the precipitation once gets to eagle
overnight tonight into Monday morning to be snow. Other areas
across the eastern alaska range have remained with snow through
the morning. Removed the warnings across the central interior and
eastern alaska range at noon today. There will still be some snow
through the late afternoon and early evening with less than 1
inch overnight. As precipitation decreases from west to east
tonight into Monday there will be an increase in winds as the
surface pressure gradient tightens along the dalton highway
between livengood and coldfoot. Only expecting sustained winds 20
to 25 mph with gusts 30 to 35 mph Monday afternoon.

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.

Afg watches warnings advisories
High surf advisory for akz213.

Heavy freezing spray warning for pkz210-pkz220-pkz225.

Gale warning for pkz210-pkz220-pkz225.

Brisk wind advisory for pkz230.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
