Discussion
A storm in the western interior and west coast winds down while a
new storm brings significant rain and snow to the eastern and
central interior.

Central and eastern interior:the 984 mb low currently located
over southwest yukon continues to move to the north northwest and
will stall near eagle Tuesday morning. A strong trough extends
west of the low along and will extend along an eagle to fairbanks
to tanana to lake minchumina line Tuesday morning and will linger
in place and slowly weaken into Wednesday. The 12 model suite
continues to indicate a very moist system with nearly an inch of
liquid precip forecasted beginning this evening and continuing
through Wednesday morning in the southern fortymile country most
of which will fall as snow in the higher terrain where 8 to 12
inches of snow still looks on target. Around a half of an inch of
liquid precipitation is expected over fairbanks with heavier
amounts to the north and east. The models continue to struggle
with the timing of the transition of the rain to snow especially
in the lower elevations this evening. Rain is expected to
transition to snow around midnight a valley level near fairbanks
and will limit storm snowfall accumulations through Wednesday
morning to the 3 to 6 inch range while while locations in the
hills and over highway summits to the north of fairbanks are
expected to receive 6 to 9 inches of snow through Wednesday
morning. The higher terrain including the dalton and steese
highway summits in zone 220 are also expected to receive 6 to 10
inches of snowfall through Wednesday morning. The timing of the
transition from rain to snow, as well as ground temperature will
greatly affect snowfall accumulations in valley locations. Tanana
is expected to receive around 4 inches of snowfall through
Wednesday morning and the higher terrain including the elliott
highway in zone 221 is expected to receive between 6 and 9 inches
of snowfall. Winter storm warnings have been issued for these
areas. Winter weather advisory has been issued for zone 216 where
1 to 3 inches of snow is expected at valley level and up to 5
inches in the higher terrain to the east of galena. A winter
weather advisory remains in effect for the eastern alaska range
passes where several inches of snow combined with gusty winds
will produce reduced visibilities in blowing snow.

North slope and brooks range: the combination of a trough moving
north through the interior combined with persistent strong high
pressure over the arctic ocean will tighten up the pressure
gradient along the northern slopes of the brooks range and the
north slope. Northeasterly winds continue to develop as the
pressure gradient tightens up with many locations along the coast
seeing gusts as high as 40 mph. When the winds increase, we expect
blowing snow to develop across most of the north slope. Winter
weather advisories for blowing snow were issued by the previous
shift for zones 201, 202, 203, 204, 205 and 206. These advisories
look to be in good shape. Gusty winds along the coast look to
persist into Wednesday. Other than some light snow across the
arctic plain on Tuesday, we aren't expecting any precipitation
this week.

Western interior and west coast: the heavy snow is expected to
diminish this evening however there will remain a chance of light
snow or snow showers over the most area through Wednesday
morning. Snow is expected to develop again tonight especially to
the east and south of galena where a winter weather advisory
remains in effect for zone 216 as a trough associated with the
low moving north along the canadian border brings several inches
of snow accumulation to the area through Wednesday morning.

Coastal hazard potential days 3 and 4... None.

Fire weather
A 984 mb low over the southwest yukon will continue to move north
along the canadian border and will stall near eagle through
Wednesday. The low will continue to bring moisture into the
interior through early Wednesday. This will help to keep the
minimum rh values above 40% for most of the area into Wednesday.

Significant rain and snow is expected across much of the interior
late Monday into Wednesday morning.

Hydrology
Cooler than normal temperatures over the eastern interior will
continue through the middle of the week and will slow the breakup
process. Extreme caution should be used crossing any of the
interior rivers as the ice continues to rot and be eroded from
below, and any runoff will be moving into the mainstem rivers.

Caution should also be used on lakes as the ice melts at different
rates.

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.
