Synopsis An upper trough over the region will maintain cool
and showery pattern today. Snow showers above 2,000 feet could
produce a few inches of snow in the passes. A stronger and wetter
front will bring more rain, mountain snow and windy conditions
late Saturday night and Sunday. Additional fronts will will keep
the weather active through next week with temperatures trending
below normal.

Short term The strong pacific system that generated large
swells yesterday has now weakened offshore. Central pressure is
around 988 mb. This system will continue to fill weaken today as
it moves inland through the queen charlotte sound. Seas will
continue to subside and will fall below 20 feet during the
morning hours. A high surf advisory remains in effect until noon
pst today for the pacific beaches.

Across western washington, moist and unstable SW flow continues
for mainly scattered showers. Showers will increase in coverage
this afternoon and evening as a trough axis moves inland. The
cooler air mass will knock snow levels down to around 2,000 ft in
the mountains with generally 1-5 inches of snow expected.

Temperatures will trend close to normal across the lowlands.

Showers will decrease on Saturday, mainly in the interior, as a
weak upper level ridge moves inland. The mountains will continue
to see showers with westerly flow aloft.

A wetter pac system will bring more rain and wind Saturday night
and Sunday. Pressure gradients tighten with strong S SE flow
along the coast and north interior - high winds are possible.

Snow levels remain low in the mountains with heavier snow
expected, including the passes. The weather will remain cool and
showery through Monday with moist westerly flow aloft. 33

Long term The weather will remain unsettled through next week
as a series of fronts track through the pac nw. There's little
break in the action. Late in the week, models show a cool upper
level trough overhead with heights in the 530s. This keeps snow
levels low, near 500-1000 ft. It's possible we could see rain snow
showers on the higher hills. However, with southerly onshore flow
snow amounts look spotty and light. 33

Aviation A deep low pressure system centered near 50n 131w
will slowly fill as it moves eastward today then onto the central
british columbia coast tonight. A cool, moist, and unstable air
mass rotating around this low will give showers to the area today.

Showers will increase later this afternoon and tonight as the
upper level trough associated with the offshore low moves onshore.

Strong southwest flow aloft will weaken and turn westerly this
evening as the upper trough passes.

Conditions are generallyVFR across the region with pockets of
MVFR ceilings in showers. ExpectVFR conditions with MVFR
conditions at times around showers to continue through the day
today. Conditions will deteriorate to lower end MVFR later this
afternoon and tonight as the upper level trough offshore pushes
inland. The 12z terminal forecasts will generally be extensions of
the previous forecast. Albrecht
ksea... MainlyVFR conditions with showers at times for much of
today. Conditions will deteriorate to low end MVFR later this
afternoon through tonight with an increase in shower activity.

Winds will be south 10-14 knots through this afternoon then will
increase to 13 to 17 knots with gusts to 27 knots after about 00z
this afternoon as the upper level trough moves through. Albrecht

Marine A deep low near 50n 131w will fill as it moves onto the
central british columbia this evening. Scatterometer data from a
polar orbiting satellite shows near a broad expanse of 25 to 35
knot winds to the south of this old low continuing offshore. Small
craft advisory winds and hazardous coastal seas will continue
through tonight as a trough and the system's wind field push
inland this afternoon through tonight.

Another strong front offshore will move into the offshore waters
Saturday night and push inland Sunday morning. Models show the
strongest winds with this front just to the south of the forecast
area, but gales can be expected over the coastal waters, and
possibly the entrances to the strait of juan de fuca and the
northern inland waters ahead of the front. At this time will issue
a gale watch for Saturday afternoon through Sunday morning for
the coastal waters. The watch will likely need to be expanded
eastward with the next forecast.

An active weather pattern with several strong fronts will continue
during the upcoming week. Albrecht

Hydrology River flooding is not expected for the next 7 days.

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.
