Discussion
An area of low pressure centered near eagle this afternoon will
continue east into the yukon territory tonight and into the
northwest territories of canada by Thursday. Precipitation from
this system will diminish from west to east this evening and
overnight.

Behind this system, after a brief period of clearing across
portions of the interior, a trough extending south from a low
pressure center entering the beaufort sea from the north will
bring showers into the north slope and into portions of the
central interior as early as tonight, spreading south and eastward
thu into the brooks range and the eastern interior. As with the
previous system, higher elevations along the brooks range could
see two to three inches of snow with this. Rainfall amounts are
expected to be light with just some isolated showers, mainly west
of fairbanks, along the alcan border, and near the alaska range.

A second system dropping into the chukchi and beaufort seas
immediately after will bring precipitation and increased
northerly winds to the northwest arctic coast and the west coast
thu afternoon. Expect northerly winds in the 20 to 25 kt range
along the west coast and through the bering strait Thu afternoon
through fri. Some beach erosion may be possible with some elevated
surf from utqiagvik to shishmaref to savoonga. This system will
spread east Thu night through Friday, and the northerly winds
will diminish in intensity almost as soon as the system moves
inland. Precipitation will be more widespread from the brooks
range north, and more showery across the interior. The most likely
chance for the eastern interior receiving precipitation from this
will be during the day Friday as the trough axis moves over a
near surface low generally in the yukon flats to the fortymile
county with a weak front extending through fairbanks and into the
alaska range. Expect another 2 to 4 inches of snow will be
possible Fri night Sat with this system. Isolated showers may be
possible Sat over the interior as well as the surface low either
dissipates or moves off to the east, depending on which model
solution wins out. Expect just a little more precipitation with
this system, from around a quarter of an inch on the north slope
and brooks range to one to two tenths of an inch from fairbanks
south.

Precipitation will likely linger along the north slope as several
shortwaves will move across from west to east this weekend. Model
solutions are not quite in line with the strength of the
shortwaves, but right now it looks like showers as well as
westerly winds of 15 to 25 kts, maybe stronger, are a good bet
across the north slope from Saturday morning into at least early
next week.

Coastal hazard potential days 3 and 4...

a 500-600 mile fetch of the chukchi bering seas with N winds
blowing 20-25 kt from late Thu into early Sat will cause elevated
surf at shishmaref and the bering strait Thu pm into Sat am. At
this time we do not expect high surf as high surf normally
requires winds 25kt or greater, but there normally is not a 500+
mile fetch length for several days, so this needs to be watched as
we get closer to thu, fri. From utqiagvik west, expect NW winds
15-20 kt from late Fri through sun. This would cause elevated surf
from utqiagvik from late Fri into sun.

Fire weather
Highs are expected to remain in the 50s to mid 60s across the
interior and west coast through the weekend. Expect rh to remain
near or above 40% through the weekend. Expect increasing winds on
fri in the western interior but the winds will be accompanied by
moisture and cooler temperatures.

Hydrology
As river levels have decreased, we have been able to cancel all
remaining flood advisories. That being said, river levels will
remain high for the next few days across the tanana and chena
river basins. Ponding of water in low lying areas will still be
evident over the next few days as flooded or high water areas
slowly drain out. Even with the showers in the forecast, river
levels will continue to drop through the remainder of the week.

Afg watches warnings advisories
None.

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.
