Severe Weather Alert Descriptions

 Areal Flood Warning  Statement as of 3:21 PM PDT on April 20, 2014


... The Flood Warning remains in effect until 445 PM PDT Thursday for
north central Snohomish County...

* Flood Warning for the North Fork stillaguamish river east of the
State Route 530 slide in north central Snohomish County...

* until 445 PM PDT April 24.

* Flooding continues on the North Fork of the stillaguamish river
upstream of the sr 530 slide due to debris from the State Route
530 slide partially blocking the river and the resulting pooling
of water behind the debris dam. We will be updating the Flood
Warning on a day to day basis.

* The Oso area has received 0.80 inches of rain in the past 24
hours... and heavier amounts were reported north and east of the
landslide area. This resulted in rises on the North Fork of the
stillaguamish river last night. Mainly dry conditions are expected
through mid afternoon Monday... this will allow the river and slide
pool to slowly recede through Monday.

* At 230 PM PDT Sunday... the North Fork of the stillaguamish river
near Arlington was at 5.5 feet or 4195 cfs. The North Fork of the
stillaguamish near Oso was at 217.0 feet... or 2360 cfs. The river
crested around 6 am this morning and will slowly recede through
Monday.

* At 230 PM PDT Sunday... the elevation of the slide pool to the east
of the sr 530 landslide was 284.2 feet. The pool elevation is
forecast to recede to around 283.6 feet by late Monday afternoon.
There continues to be a great amount of uncertainty in the forecast
pool elevation due in part to limited knowledge of how much water
the new stream channel through the slide debris will be able to
convey.


Precautionary/preparedness actions...

A Flood Warning means flooding is occurring or imminent. Most flood
related deaths occur in automobiles. Do not attempt to cross water
covered bridges... dips... or low water crossings. Never try to cross a
flowing stream... even a small one... on foot. To escape rising water
move up to higher ground.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
910 PM PDT sun Apr 20 2014 


Synopsis...high pressure will give mainly dry weather to the area 
tonight. A stationary front just off the coast will bring an 
increasing chance of showers to western Washington through Monday as 
the air becomes unstable. The front will move inland Monday night. 
Additional weather systems will give cool and unsettled weather 
through next weekend. 


&& 


Short term...a front is stalled just off the coast this evening and 
the radars show rain just offshore. The combination of the air 
become unstable Monday and diffluent south-southwest flow aloft should allow 
showers to increase Monday...becoming more widespread Monday night 
as the front and its associated upper trough finally move inland. 
Cool onshore flow and the upper trough will give a showery cool day 
on Tuesday. The rest of the upper trough will follow Tuesday night and 
Wednesday for cool weather and more showers. A warm front will approach 
the area later Wednesday. Temperatures across the region through Wednesday will be a 
few degrees below normal. 


Long term...large scale models bring a wetter and more organized 
frontal system across the area Wednesday night through Thursday or Thursday night. 
Per conversations with NESDIS...this system...currently near the 
international dateline...has some tap to subtropical moisture from 
the western Pacific and may result in some moderate precipitation 
amounts. This has been advertised by all of the global models for 
several days now. Behind that system...mean upper troughing over the 
eastern Pacific will maintain cooler and wetter than average 
conditions for late April. Albrecht 


&& 


Hydrology...river flooding is unlikely for the next 7 days. 


The exception is the North Fork of the stillaguamish river east of 
the sunrise 530 landslide near Oso where a Flood Warning remains in 
effect until further notice. Flooding continues for this river as a 
result of water pooled behind the debris dam that partially blocks 
the river. 


At 230 PM...the North Fork of the stillaguamish near Arlington is 
at 5.5 feet...or 4195 cfs. The river will recede to around 4.5 feet 
late Monday afternoon. The North Fork of the stillaguamish river 
near Oso is at 217.0 feet or 2100 cfs. The river will recede through 
late Monday. The slide pool east of the landslide is at 284.2 feet. 
It will also slowly recede through Monday. Albrecht 


&& 


Aviation...high pressure aloft will shift eastward tonight as a trough 
develops offshore. The trough and associated surface front will 
slowly push into western Washington Monday and Monday night. Moderate S/SW flow 
aloft. Stable atmosphere and somewhat moist aloft but mainly dry in 
the low levels. The low level air mass will gradually moisten up 
through the day Monday. 


Ksea...ceilings expected to remain above 5k feet tonight into Monday. Light 
wind...becoming northwest 3-6 knots Monday afternoon. Dtm 


&& 


Marine...a cold front will dissipate over the waters this evening. 
Winds will remain below 20 knots throughout. A small craft for 
hazardous seas continues through Monday for the coastal waters and 
West Entrance to the Strait. Westerly swell around 14 feet over the 
coastal waters will subside to near 12 feet on Monday. Swell at the 
West Entrance around 13 to 14 feet will subside to near 10 feet on 
Monday. 


A high surf advisory will expire at 9 PM PDT. Observation indicate that 
waves reaching the coast have fallen below 15 feet...but large waves 
above 10 feet will continue through Monday. Therefore...those 
planning on beach activities should still be alert for waves 
suddenly racing farther up the beach than normal 


&& 


Sew watches/warnings/advisories... 
Washington...Flood Warning remains in effect for the North Fork of the 
stillaguamish river east of the sunrise 530 landslide. 


Pz...Small Craft Advisory for hazardous seas coast and west Strait 
of Juan Delaware fuca through Monday evening. 
Small Craft Advisory for rough Grays Harbor bar through Monday 
morning.
