Discussion
An active pattern continues for the west coast as a series of lows
will move north through the bering sea over the next seven days.

A strong ridge will build northward today over the interior. This
will help to keep the interior mostly free of precipitation for
much of the upcoming week.

Central and eastern interior: a front associated with a low in the
bering sea will keep the interior mostly cloudy today. With the
exception of areas northwest of tanana, we aren't expecting any
accumulating snowfall with this front today. A strong ridge will
build northward tonight. This ridge will keep the interior mostly free
of measurable precipitation for the upcoming week. As the ridge
builds northward, we expect skies to clear out tonight. The ridge
will shift to the east some on Sunday night and Monday. This will
allow a front to bring increased cloud cover to areas north and
west of fairbanks. A general warming trend is expected through
Monday across the interior as warmer air builds in aloft. I am a
bit concerned that the guidance is a bit too warm especially in
the valley locations where a strong inversion is likely to form at
nighttime in areas under mostly clear skies.

West coast and western interior: a front associated with a low in
the southern chukchi sea is currently bringing strong winds, snow
and blowing snow to much of the west coast. There is a great deal
of warm air with this system. Thus, the snow is mixing with, or
changing over to freezing rain at times all along the coast. The
precipitation will taper off from south to north today and winds
will die down some as the first low continues to move to the
northeast. Any improvement will be short lived. A front associated
with a low that is currently moving north through the bering sea
will move north across the west coast tonight into Sunday. This
will bring another round of strong winds, snow (mixed with
freezing rain at times) as well as blowing snow. Precipitation and
strong winds with the second front will taper off from south to
north Sunday afternoon and evening. Another round of precipitation
is expected along the coast on Monday, although the winds don't
look to be quite as strong with this round. Several additional
waves of precipitation will move north along the coast through
the upcoming week.

North slope and brooks range: a front associated with a low in the
southern chukchi sea will move to the east today across the arctic
coast (mainly to areas west of deadhorse). The front will also
bring gusty winds causing reduced visibility, primarily west of
utqiagvik. The precipitation will continue into this evening.

Warmer air moving in aloft may cause the snow to mix with or
change over to freezing rain this evening before the precipitation
ends this evening. The combination of the low moving through the
chukchi sea and high pressure over the interior will keep a tight
pressure gradient across the brooks range today resulting in gusty
southerly winds. The gradient will relax some tonight as the low
moves off to the north. The gradient will tighten up again Sunday
causing the gusty southerly gap wins to return.

Coastal hazard potential days 3 and 4... Strong southerly winds
are expected across the eastern bering sea and the west coast of
alaska through tonight. Expect sea levels to rise up to 3 feet
above normal in most areas this weekend. This may cause water to
seep into low lying areas along the coast, such as along rivers
and sloughs. At this time no flooding is expected, but travelers
should be aware of water moving onto sea ice and river ice near
the coast. The highest sea levels should be tonight through early
Sunday morning.

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.
