...SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS IN EFFECT UNTIL NOON
PST TODAY...

The National Weather Service in Seattle has issued a Small Craft
Advisory for hazardous seas...which is in effect until noon PST
today.

* SEAS...West swell 10 to 11 feet at 12 seconds.

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.

What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Seattle, WA wrote its last area forecast discussion before this small craft advisory went out at Jan 1, 9:20 AM PST, 4 hours 4 minutes earlier.

Area forecast discussion, Jan 1, 9:20 AM PST, 4 hours 4 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
920 AM PST Mon Jan 1 2018

.SYNOPSIS...An upper level ridge remain over or near Western
Washington through Wednesday, with drying low-level offshore wind
flow. The ridge will shift east Wednesday night allowing a weak
system to move across the area from the south on Thursday. A
wetter system will arrive on Friday.

&&

.SHORT TERM...An upper ridge axis will hang out between the coast
and Central Washington between now and late Wednesday, keeping the
weather dry and the air mass stable or inverted. Some temporary
flattening of the ridge on Tuesday will be of little consequence
other than to thicken mid-high clouds on Tue PM. Low-level
offshore flow will keep the lower air mass dry. With a northeast
wind spreading dry continental air past Bellingham and across
Northwest Washington, A.M. fog and low clouds will mainly favor
the South Sound Region and valleys of Southwest Washington, i.e.
SHN, TCM, OLM, and CLS. Easterly pressure gradients will keep it
breezy at times near the Cascade foothills of King and Snohomish
Counties. All in all, a quiet start to 2018.  Haner

.LONG TERM...From Previous Discussion: Models in good agreement
early on in the extended with the upper level ridge moving east
and a splitting system moving up from the south on Thursday. With
the offshore surface gradients remaining in place will only go for
a chance of rain on Thursday and Thursday night. A more
consolidated system embedded in the southerly flow aloft moving
into the area on Friday and Friday night for a better chance of
rain. Model solutions become inconsistent over the weekend with
the GFS digging a surface low south along the Oregon coast on
Saturday with some upper level ridging off the coast. The ECMWF
has a surface ridge building into the Coastal waters on Saturday
with a warm front moving over the top of the ridge trying to get
into western Washington on Sunday. The GFS has a similar scenario
for Sunday with a stronger surface low associated with the front.
For now will leave the chance pops forecast for the weekend going
for another forecast package. Felton

&&

.AVIATION...An upper ridge will remain over Western Washington
through Tuesday. At the surface, high pressure to the northeast of
the area will give light northeasterly winds through Tuesday.

The air mass across the area is dry and stable except for some
high level moisture and some low level moisture trapped below a
shallow surface based inversion over southern portions of the
interior lowlands. The more extensive fog and stratus is seen
over the south interior from about KTIW and KSHN southward. The
stratus and fog will gradually erode through mid afternoon then
form in the same areas again tonight.

Offshore pressure gradients will decrease somewhat Tuesday
morning. Normally, areas from about KSEA northward in the
interior would see an increase in fog as the gradients decrease.
However, an increase in high level moisture that is expected
Tuesday morning may counter the fog formation. Confidence in the
fog forecast for late tonight and Tuesday morning for areas from
KSEA northward is lower than usual. Albrecht

KSEA...Cameras show low stratus and fog to the east and southeast
of the terminal remaining in place and gradually decreasing.
Expect good VFR conditions at the terminal this afternoon and
tonight. Winds will be NE 7 to 10 kt early this afternoon
decreasing to 5 to 7 kt tonight through Tuesday morning. Fog may
be more extensive in the valleys to the east of the terminal
Tuesday morning and may impact the terminal after 13Z, but
confidence is not high. Albrecht

&&

.MARINE...Offshore flow across the waters will continue through
the end of the week as high pressure remains to the east of the
Cascades and lower pressure remains offshore. Small craft advisory
east winds are expected at times in the West Entrance to the
Strait of Juan de Fuca and in the adjacent northern coastal waters
out to 10 nm offshore.

A front will approach the waters from the west or southwest
Thursday night or Friday increasing the offshore pressure
gradients. Albrecht

&&

.HYDROLOGY...No flooding is expected for the next 7 days.

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...None.
PZ...Small Craft Advisory until 1 PM PST this afternoon for Coastal
     Waters From Cape Flattery To James Island Out 10 Nm-West
     Entrance U.S. Waters Strait Of Juan De Fuca.
