Discussion
We have a few issues that we are dealing with today across the
forecast area. Hot and dry conditions are expected today across
the eastern interior. The hot and dry conditions will be combined
with gusty chinook winds on the north side of the eastern alaska
range resulting in red flag conditions. Elsewhere, the koyukuk
river will remain high over the next few days. A flood warning is
currently out for allakaket while a flood advisory remains in
effect for just downstream of allakaket to hughes. Overall, the
models initialize well and are in decent agreement out through
Monday night before they begin to diverge on the main synoptic
scale features.

Aloft, at 500 mb, a ridge currently stretches from the southern
yukon territory along the canadian border and over the north
slope. A 526 dam low is currently situated near nikolski. This
pattern will result in southerly flow over much of the forecast
area that will persist into Tuesday. A 533 dam low will move north
into bristol bay this evening. This disturbance will move north
along the coast Sunday night and Monday, and by Monday evening
will be north of the bering strait (although there is some
uncertainty in the exact position by this point). The models
diverge on the handling of this low Monday night, with the gfs
and the ECMWF moving the low over the chukotsk peninsula Tuesday,
while the NAM keeps the low over the chukchi sea coast of alaska.

Central and eastern interior: warm and dry conditions will
continue today across the interior. A wide swath of the interior
will see temperatures in the mid to upper 70s today with a few
locations expected to reach the 80 degree mark. Gusty southerly
gap have been observed overnight near the alaska range with some
stations seeing gusts of 40 to 50 mph. The winds may decrease a
bit this morning, but we expect the winds to ramp up again this
evening. I opted to issue wind advisories for zones 223 and 226
for this evening into early Monday when winds gusts as high as 50
mph are possible (mainly along the richardson highway south of
delta junction). The winds will gradually die down during the day
on Monday. Monday generally looks to be slightly cooler than
Sunday for most locations, with the cooling trend continuing on
Tuesday. The interior is expected to be free of precipitation
today. Tonight into Monday, a disturbance moving north along the
west coast will bring chances for rain showers, primarily areas
northwest of tanana. Scattered showers are possible across much of
the interior on Tuesday.

West coast and western interior: a front associated with a low in
the bering sea will bring some rain today to the seward peninsula
as well as the chukchi sea coast. A front will some rather heavy
rainfall as it pushes north across the western interior tonight.

The rainfall will move over the west coast on Monday. This system
will bring a quarter of an inch of rainfall to most of the western
interior. Some locations (especially in upslope areas just south
of the brooks range) will see rainfall amounts of 0.75 to 1.0
inches with this system. Rainfall will taper from southeast to
northwest Monday nigh into Tuesday. A surface low will move to the
northwest through the western interior on Monday and into the
southern chukchi sea Monday evening. As the low moves to the
north, it will cause gusty southerly winds to develop across most
of the west coast and the western interior.

North slope and brooks range: high pressure over the arctic will
bring easterly winds today along the arctic coast. The easterly
winds will continue to bring fog and low clouds to the arctic
coast today. A surface low moving north through the interior will
cause the pressure gradient to tighten up along the arctic coast
resulting in increased easterly winds on Monday. The surface low
will move north of the brooks range by Monday evening. This will
cause strong southerly gap winds to develop in the western brooks
range. The strongest winds will mostly push offshore by Tuesday
morning as the surface low moves into the southern chukchi sea. A
front will spread precipitation across the brooks range early
Monday morning with the precipitation spreading over the north
slope by Monday afternoon. The precipitation type generally looks
to be rain; however, along the coast, we are expecting a mix of
snow and rain (or possibly even freezing rain) as the system moves
through. Precipitation will taper off from south to north Monday
night.

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

Fire weather
Warm and dry conditions will persist across the interior today. A
trough of low pressure north of the alaska range will result in
persistent southerly gap winds near the north side of the alaska
range. The good news is that the strongest winds are expected late
tonight. None the less, red flag conditions are expected today for
zones 223 and 226. Tomorrow we expect slightly cooler
temperatures and slightly higher minimum rh values across the
interior, with this trend continuing on Tuesday. A wetting
rainfall is expected across the west coast and the western
interior tonight into Monday.

Hydrology
High water on rivers draining the south side of the brooks range
will continue through the week. The flooding at allakaket is
forecast to crest today and will then fall very slowly. At hughes,
the flooding is expected to crest Monday, 1 ft higher than now,
then fall slowly. At huslia waters will rise slowly for the next
week, then fall very slowly, making at least 10 more days of bank
erosion likely there.

On the north side of the brooks range, a return to high freezing
levels today into next week will see rising rivers this week.

A significant rainfall is expected across the west coast, western
interior and the western brooks range tonight into early Monday.

Afg watches warnings advisories
Red flag warning for akz223-akz226.

Small craft advisory for pkz230.

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.
