Severe Weather Alert Descriptions

 Areal Flood Watch  Statement as of 4:38 am PST on November 28, 2014


... Flood Watch remains in effect through this afternoon...

The Flood Watch continues for

* portions of western Washington... including the following
counties... Skagit... King... Lewis... Mason... Pierce...
Snohomish... Thurston.

* Through this afternoon

* heavy rain will over across western Washington today as a
strong cold front moves south through the area. The frontal band
will bring 1 to 2 inches of rain to the west slopes of the
Cascades today as it moves through. The snow level will be
around 5000 to 6500 feet ahead of the cold front... falling
quickly to around 2500 feet in its wake.

* Many rivers flowing off the west slopes of the Cascades are
running high... especially from King County northward. The
additional rain today could drive some of them above flood
stage. Where flooding does occur... it is expected to be
relatively minor.

Precautionary/preparedness actions...

A Flood Watch means that flooding is possible but not occurring.
Monitor the weather and be ready to act quickly if flooding is
observed or flood warnings are issued.





 Special Statement  Statement as of 3:36 am PST on November 28, 2014


... Much colder conditions will spread into the area through Saturday...
... Some lowland snow is expected over portions of the interior
later tonight into Saturday morning...
... Cold and windy conditions are expected to develop over the
north interior this evening...

Temperatures will fall through the 40s today then into the 30s
this evening as a cold upper level trough develops over the area
behind this morning's cold front. As the temperature cools behind
the front today... expect rainfall to taper off from the north.

A Puget Sound convergence zone is expected to form between north
King County and central Snohomish County this evening and continue
through early Saturday morning. Snow levels are expected to drop to
below 300 feet overnight as the air mass cools. One to three
inches of snow are possible in the convergence zone area by early
Saturday morning.

Some brief lowland snow... with accumulations less than an
inch... is possible Saturday morning over the remainder of the
western Washington lowlands from Seattle southward as a modified
Arctic frontal system drops from the north interior southward
through western Washington.

Expect cold and windy conditions to develop over the north
interior of western Washington this evening and continue through
Saturday. Northeast winds of 25 to 40 mph with gusts to 55 mph are
possible from western Skagit County and the San Juan Islands
northward into western Whatcom County. A high wind watch is in
effect for tonight and Saturday for this area. The windy
conditions will be accompanied by temperatures in the 20s to give
wind chill temperatures in the lower teens.

Stay tuned to the latest updates from the National Weather
Service in Seattle.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
310 am PST Friday Nov 28 2014 


Synopsis...a cold front will move southeastward across the area 
this morning. Locally heavy rain is expected ahead of this front. A 
convergence zone will continue over northern portions of the Puget Sound 
sound area tonight with snow levels lowering to below 300 feet 
overnight. A modified Arctic cold front will move south through the 
area late tonight into Saturday morning. Some snow showers can be 
expected as this front moves south across the area Saturday morning. 
Weak high pressure aloft and low level offshore flow will bring 
mainly cool and dry weather Sunday through early next week. 


&& 


Short term...at 2 am a Pacific cold front dropping southeast from 
the Gulf of Alaska extends from near Vancouver British Columbia to around 
Destruction Island on the north coast. Temperatures are quite mild 
ahead of the front with middle 50s in many locations. Observations over 
Vancouver Island and through the Strait of Georgia showed 
temperatures falling from the lower to middle 50s down into the middle 40s 
in one hour as the front passed. The front will move through the 
Seattle area during the morning hours then southeast of the area 
after noon. Maximum temperatures are occuring this morning and will 
fall into the middle 40s as the front passes. Locally heavy rain is 
falling ahead of and with this front. See the hydrology section 
below for details on how the rain will affect local rivers. 


A brief lull in precipitation can be expected behind the front this 
afternoon. The forecast then becomes uncertain this evening into 
Saturday morning as a deep upper level trough digs offshore just 
west of Vancouver Island then moves southeast across the area...and 
is combined with a southward moving modified Arctic front coming 
down from the interior of British Columbia. The 06z GFS is somewhat 
dry across much of the area tonight except at the leading edge of 
the Fraser outflow and modified Arctic front where a brief inch of 
snow locally occurs in the interior. The nam12...Canadian...and 
European model (ecmwf) models show 1-3 inches of snow late tonight into Saturday 
morning with a convergence zone then the modified Arctic front. The 
minor differences between the wetter/stronger European model (ecmwf) and weaker/drier 
GFS is in the amount of digging of the upper level trough to the 
southwest over the coastal waters...which would hang up the frontal 
boundary over the central Puget Sound sound area around Everett tonight 
into early Saturday and provide more low level convergence with the 
boundary. At this time the forecast will be a blend of all models 
that brings possible advisory snow amounts to the Everett and 
vicinity zone and the north portion of the east Puget Sound sound 
lowlands. A mention of up to an inch of snow will be made for the 
other interior zones with the exception to where outflow becomes 
strong around the San Juans and western Whatcom County. Will allow 
the day shift to look at the 12z guidance before issuing any winter 
weather advisories for the interior lowland zones and will freshen 
the Special Weather Statement. 


Concerning wind...the Bellingham-Williams Lake pressure gradient has 
fallen below -8 mb and continues to rapidly fall. It is expected to 
reach around -20 mb midday and continue quite strong through 
Saturday. With a lag between the gradient and the wind reaching the 
northwest interior...winds are expected to rapidly ramp up to NE 25-35 miles per hour 
with gusts to 45-50 miles per hour this evening. High winds are possible in the 
Fraser outflow areas...but are not certain yet...so a high wind 
watch will be maintained for now. After looking at the 12z guidance 
the next shift will have a better idea as to whether the winds will 
become damaging...or will remain in the advisory range. 


Conditions will clear and dry from the north on Saturday and it will 
be quite cold across the area. Temperatures will struggle to hit 
freezing from Seattle southward and will likely remain below 
freezing north of Seattle on Saturday. After a hard freeze Saturday 
night...temperatures will begin a slow moderation starting on 
Sunday. Albrecht 


Long term...northern stream systems dropping southeast from the 
Gulf of Alaska...or southern stream moisture wrapping northward from 
off California. Models still cannot come to any agreement over the 
Pacific northwest where flow will remain somewhat confluent. The 
European model (ecmwf)...nam12 and Canadian solutions weaken northern stream systems 
before they move into Washington during the period. The 06z GFS is 
aggressive in bringing southern stream moisture into SW Washington 
Monday-Thursday rain there and more clouds to the north. Forecasts for now 
will be kept dry with partly cloudy conditions and temperatures will 
be forecast to slowly moderate toward normal. Albrecht 


&& 


Hydrology...there was a relative lull in the rainfall on 
Thursday...with up to 2 inches of rain over the Olympics and north 
Cascades near Mount Baker and generally less than 1.2 inches in the 
Cascades further south. That was less than we had forecast. 


A strong cold front is moving into the north part of western 
Washington from the north early this morning. It will move rather 
quickly south through the area today...and then southeast of 
Washington this evening. The frontal band will bring about a 12 hour 
period of heavy rain to the Cascades as it moves through...which has 
already started over the north Cascades. That is nothing exceptional 
when we think of systems that could produce flooding...but most of 
the rivers -- especially from the Snoqualmie northward -- are 
already running high. So it could be enough to drive some of them 
above flood stage. Where flooding does occur...it will probably be 
relatively minor. 


In the Cascades of Whatcom and Skagit counties...rain increased 
overnight with the arrival of the cold front and generally 0.5 to 
1.5 inches fell in the past 6 hours. This area...which affects the 
Nooksack and Skagit rivers...will only receive hydrologically 
significant rain for another 6 hours or so...but it should be as 
heavy or a little heavier than the last 6 hours. The Skagit...where 
a Flood Warning is in effect...is rising and close to reaching flood 
stage. The Nooksack is rising sluggishly...but it is within a couple 
feet of flood stage. Being further north...the Nooksack basin might 
not get enough rain this morning to push the river above flood 
stage. For now it remains in the watch area...but a Flood Warning 
could be issued anytime this morning. 


Over the Cascades of Snohomish and King counties there has been 0.4 
to 1.2 inches of rain in the past 6 hours. The rivers here include 
the stillaguamish...Skykomish...Snoqualmie...tolt...and Snohomish 
rivers. This area should have heavy rain through early afternoon... 
so another 10 hours or so...with 1 to 2 inches of rain likely. The 
rivers are all running fairly high and at least their upper reaches 
are rising. The Skykomish looks like a good bet to flood this 
morning...and any of the others could flood as well. Flood warnings 
could be issued for any of these rivers this morning. 


The Cascades of Pierce and Lewis counties...which includes The Mount 
Rainier area...will also receive around 1 to 2 inches during the 
next 12 hours. However this region has had 1 inch or less of rain 
during the past 24 hours...and rivers here have receded more than 
the others. The threat of flooding on the rivers here looks fairly 
low...but it will remain under a watch for now. 


The Olympics received 0.5 to 1.5 inches in the last 6 hours. It will 
probably receive a similar amount during the next 6 hours. The 
Skokomish River rose above flood stage Thursday morning...and it 
should crest later this morning. It remains under a Flood Warning. 


Cold and relatively dry weather will follow the cold front. Rivers 
will recede and then the threat of flooding will end for the 
foreseeable future. 


Regarding the possibility of landslides...the US geological survey 
provides landslide guidance that suggests that the threat is low. 
That is mainly due to the fact that we had about 10 days with no 
precipitation before this wet period. But I think it is Worth 
mentioning that models indicate that the front could produce 6 hour 
rainfall amounts in excess of 1 inch over the Puget Sound sound lowlands 
today. Mcdonnal 


&& 


Aviation...a cold front will shift south through western Washington this 
morning bringing moderate rain and gusty winds. The flow aloft is 
westerly. MVFR conditions are likely. This front will exit south 
this afternoon with steady rain tapering off. 


High pressure over interior b.C. Will bring strong NE Fraser River 
outflow winds to the north interior tonight. Meanwhile a cool air 
mass will settle over the region tonight through Saturday afternoon 
as an upper level trough tracks overhead. This system will likely 
bring low level snow to the area...especially the Strait of Juan Delaware 
fuca and interior. The upper trough will exit late Sat afternoon or 
evening for dry weather across western Washington. 33 


Ksea...rain continues across the region this morning as a cold front 
crosses from north to south. MVFR conditions will continue through 
this morning. This front will also bring a wind shift with winds 
becoming northerly by 18z. Winds will flip back to southerly around 00z 
this evening. Late tonight into Saturday...there is a chance for 
snow at sea-tac with surface temperatures near freezing. At this point we 
are looking at accumulations of an inch or less from 12-18z Sat. 33 


&& 


Marine...a strong cold front will shift south through western Washington 
this morning. Small craft advisories are in effect for all waters. 
Winds will flip from south to north as this front pushes through 
Puget Sound sound. Winds will then turn back to southerly across the 
interior late this afternoon. Models continue to show Fraser River 
outflow winds developing this evening with NE gales over the 
northern inland waters. Gales will continue through at least Sat 
afternoon...then ease as strong high pressure over interior b.C. Shifts 
east. Offshore flow will prevail Sat night through early next week 
with high pressure east of the Cascades. 33 


&& 


Sew watches/warnings/advisories... 
Washington...flood watches and warnings in effect for portions of 
western Washington. 
High wind watch western Whatcom...western Skagit and the 
San Juan Islands tonight and Saturday. 


Pz...Gale Warning northern inland waters. 
Small Craft Advisory remaining waters. 
Small Craft Advisory Grays Harbor bar for rough bar.
