Synopsis A gale-force low west of haida gwaii will weaken then
redevelop to the NW overnight and move towards baranof island
through Thursday morning before weakening and moving inland
Thursday night into Friday. An upper low will deepen over the
aleutians this weekend with SW flow aloft maintaining precip
chances through mid next week.

Short term Tonight through Friday... Satellite imagery and
surface analysis indicate the gale force low moving into dixon
entrance this afternoon is weakening as circulation redevelops
150-200nm nw. This new low will then drift towards the coast
overnight before weakening and moving inland Thu into fri. Precip
has been slow to expand N with only the southern panhandle
observing any precip so far. Given the low will not track up the
coast, but redevelop offshore expect precip will not reach the
central and N panhandle until late this evening. Lowered pops to
reflect the updated track of the low. Majority of panhandle will
get precip Thu as the low spins offshore and slowly weakens. This
low will then move inland overnight into Fri resulting in
diminishing precip chances before another shortwave moves into
the central gulf. Main change to inherited forecast was lowering
pop over the n/central panhandle tonight using arw/nam guidance.

Long term /Friday to Wednesday/ for the start of the extended
range: at upper levels an area of low pressure over the western
gulf and aleutians with ridging building over the eastern gulf as
previous short wave moves into british columbia. The western gulf
low tracks to the east nearing the panhandle by Saturday. Upstream
another ridge builds over the central gulf as the next low moves
towards the aleutians and the pattern repeats itself for next
week. While models are in fair agreement on this pattern there are
still large enough differences to lower forecast confidence and
thus limit details being added to the forecast.

On shore flow keeps precip chances over the panhandle for early
Friday before the next surface low moves into the gulf with a
brief shift to off shore flow. While expect a low to move into the
southeast gulf Saturday moving more precip from south to north
the potential track limiting northward progression will likely
keep northern regions a bit drier. However still uncertain on the
exact track of this low. Towards the end of the weekend and start
of next week indications that an occluded front will cross into
the gulf and thus have greater impacts of increased winds and
higher pops.

Used a blend of ecmwf/gfs for Friday in an attempt to get more
transitional details. For the rest of the long range decided to
leave forecast as is due to large run to run variations. Some
fields such as temperature remain within model spectrum spreads
so were also left mostly as is.

Marine Gale force low moving into dixon entrance this afternoon
is beginning to weaken as another low begins developing 150-200nm
nw. Models show this secondary low drifting towards baranof island
overnight before moving inland Thu into fri. Model solutions
having a difficult time with this low complex but continue to
expect winds increasing over the southern gulf and inner channels
overnight into Thu then expand nwd during the day thu. A brief
period of gales over pkz042 Thu with SCA from icy strait corridor
southward.

Aviation Lowest conditions will be over the southern TAF sites
through Thu morning. MVFR ceilings will become the rule in the far
south sites this afternoon, then most central sites south of
frederick sound will have MVFR ceilings by early evening. North
tafs will stayVFR through Thu morning, except some MVFR ceilings
may get into the paya area early Thu morning. Visibility should
be mostlyVFR but occasional MVFR may occur in heavier rain bands.

Ajk watches/warnings/advisories
Public... None.

Marine... Gale warning for pkz042.

Small craft advisory for pkz022-031>036-041-043.

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.
