...SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS REMAINS IN EFFECT

...SMALL CRAFT ADVISORY REMAINS IN EFFECT UNTIL 4 PM PST
TUESDAY...

* SEAS...10 to 12 feet this evening.

* WIND...Rising to westerly 15 to 25 kt late tonight.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Small Craft Advisory for hazardous seas means that waves are
expected to be hazardous to small craft. Mariners should avoid
shoaling areas. Long period swell can sharpen into large breaking
waves in shoaling areas. It is not unusual for waves to break
much farther from shoaling areas than is normally experienced.
Remember, breaking waves can easily capsize even larger vessels.

A Small Craft Advisory means that wind speeds of 21 to 33 knots
are expected to produce hazardous wave conditions to small craft.
Inexperienced mariners, especially those operating smaller
vessels should avoid navigating in these conditions.

Area Forecast Discussion
National Weather Service Seattle WA
926 AM PST Mon Feb 26 2018

.SYNOPSIS...There will be a relative break in the weather today
as an upper ridge moves across Western Washington. The next
frontal system will arrive early Tuesday, with up to an inch of
snow in the lowlands. A stronger system will bring rainy, windy
weather late Wednesday and Wednesday night. A cool upper level
trough will settle over the area Thursday into the weekend.

&&

.SHORT TERM...Northerly flow aloft prevails over Western
Washington this morning, between the strong upper trough to our
east and a positively-tilted upper ridge centered well offshore.
Radar shows that the Puget Sound convergence zone (which brought
around 19 inches of snow to Stevens Pass yesterday) has weakened
considerably, but is still producing isolated flurries and light
rain showers in a narrow line from Port Townsend to near Stevens
Pass. There are also some showers moving onto the coast from the
coastal waters. Otherwise skies range from cloudy to partly
cloudy, with patchy fog in the Puget Sound region and south
interior. Temperatures at 8 am ranged from the mid 20s to the mid
30s.

Northerly flow aloft will continue today, and the offshore upper
ridge will progress inland across Western Washington this evening.
Showers today will be light, spotty, and mainly over the
mountains; much of Western Washington will have some sun breaks.
Highs today will be in the lower to mid 40s.

The next frontal system will spread precipitation across Western
Washington late tonight and early Tuesday morning, with the front
moving east across the Cascades around midday. Precipitation
should fall mainly as snow across the lowlands as the system
arrives, with temperatures in the lower to mid 30s and 1000-850 mb
thickness below 1300 meters across the entire forecast area.
Precipitation amounts will be light; up to one inch of lowland
snow is possible during the morning, but amounts of a half inch or
less should be more common.

The air mass will warm during the day, and the snow level should
be around 1500 ft in the post- frontal afternoon showers, which
will be mainly in the Puget Sound convergence zone and over the
mountains. Precipitation will decrease Tuesday night as a flat
upper ridge moves across the area.

A stronger Pacific frontal system will move through Western
Washington late Wednesday and Wednesday night. The air mass
accompanying this system will be a little warmer with snow levels
1000-2000 ft, so the lowlands should get rain from this system. It
will also be windy, especially along the coast and in the
northwest interior where advisory level winds are possible. The
mountains should receive a decent snowfall, especially on the
volcanoes. McDonnal

.LONG TERM...Here is the long term section from the early morning
forecast discussion -- Extended models in good agreement in the
00z run with a cool upper level trough dropping down out of the
north over the area Thursday and remaining over the area into
Saturday keeping showers and low snow levels in the forecast for
the first few days of March. Both the ECMWF and GFS kick the
trough out of the area on Sunday with the GFS going to a slightly
warmer zonal flow pattern for the first part of next week while
the ECMWF keeps the cool northerly flow aloft over the area. With
2 and a half weeks straight of below normal high temperatures
already in the books it is possible Seattle could end up with a
streak of more than 4 weeks in a row before high temperatures
return to above normal. Felton

&&

.AVIATION...Weak northerly flow aloft today will increase and turn
northwesterly tonight as a front approaches from the northwest.
Light surface gradients today will turn southerly and increase
tonight. Scattered showers are off the coast and there is a weak
convergence zone in Snohomish county. The air mass is moist and
stabilizing as weak upper ridging builds over the region.

Areas of MVFR/IFR ceilings will lift and scatter in the afternoon as
the air mass dries. High and mid-level moisture will increase once
again after 00Z as another system approaches in northwest flow
aloft. MVFR ceilings in light rain will redevelop along the coast by
12Z Tuesday. The MVFR ceilings will spread inland Tuesday morning.
Precipitation around the Puget Sound terminals Tuesday morning may
begin briefly as snow or rain/snow mix with little or no
accumulation expected.

KSEA...Improvement to VFR likely by afternoon. Increasing clouds
tonight with ceilings lowering back to MVFR 12Z-15Z Tuesday. Precip
may begin briefly as snow or rain/snow mix Tuesday morning but
little to no accumulation is expected. Light south wind this morning
becoming light and variable this afternoon. Wind becoming southerly
again tonight and increasing to 8 to 12 kt. CHB

&&

.MARINE...Weak high pressure will bring a period of lighter winds
today. Seas of 10 to 15 feet on the coast will keep a small craft
advisory for hazardous seas in effect through tonight. A weak front
will move inland on Tuesday, with small craft advisory winds
possible.

A stronger Pacific system will impact the region on Wednesday with
gales possible, especially over the Coastal Waters and the entrances
to the strait. The flow will turn offshore on Thursday as a low
moves south off the Oregon coast. CHB

&&

.HYDROLOGY...River flooding is not expected in the next 7 days.

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...None.
