Severe Weather Alert Descriptions

 Areal Flood Warning  Statement as of 3:47 PM PDT on April 18, 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 0.77 inches of rain in the last 24
hours. No rainfall is expected until midday Saturday. About 1.0 inch
of rain is expected from midday Saturday through early Sunday
morning. At 330 PM PDT Friday... the North Fork of the stillaguamish
river near Arlington was at 5.4 feet or 4076 cfs. The North Fork of
the stillaguamish near Oso was at 217.0 feet... or 2370 cfs. The
river is expected to fall about 1 foot through midday
Saturday... then rise a foot cresting early Sunday afternoon.

* At 300 am PDT Friday... the pool elevation was 286.2 ft.

* The pool elevation is forecast to fall to 284.5 feet by late
Saturday afternoon... then rise to 285.2 feet midday Sunday. 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 
905 PM PDT Friday Apr 18 2014 


Synopsis...a front will move through the area Saturday. Showers 
will taper off Saturday night and Sunday. Another front will affect 
the area Sunday night and Monday. The weather will remain cool and 
unsettled through through the end of next week. 


&& 


Short term...weak high pressure tonight and then the next vigorous 
frontal system will move through the area Saturday for another round 
of breezy wet weather. Showers Sat will taper off Sat night into 
Sunday as high pressure builds into the area. Another frontal 
system will move to area Sun night or Monday morning. The front will 
stall and pivot north-S along the coast...giving rain on the coast and a 
chance of rain for the interior. There will be a chance of showers 
Monday as an upper trough moves toward the area. 


Long term...long term models generally show progressive short wave 
systems moving through the area Tuesday and Wednesday giving a chance of 
showers at times. A more well defined front appears that it will 
move across the area Thursday or Thursday night. While there will be a 
tendency for conditions to be unsettled...the timing of individual 
features is uncertain with the European model (ecmwf) and GFS showing some timing 
differences. Will show higher probability of precipitation for Thursday than the other days in 
the extended...but overall the long term forecast will be a broad 
brush. 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 3 PM...the North Fork of the stillaguamish near Arlington is at 
5.6 feet...or 4200 cfs and is falling. It is expected to fall to 
around 4.5 feet early Sat afternoon then rise back up to 5.2 feet midday 
Sunday before resuming a fall back down to around 4 feet early next 
week. Similar trends are expected on the North Fork of the 
stillaguamish near Oso and at the sunrise 530 slide pool to the east of 
the landslide. Albrecht 


&& 


Aviation...upper level high pressure quickly shifts eastward tonight. A 
trough will move through western Washington Saturday. The associated surface 
front reaches the coast by late morning...then pushes through 
interior western Washington midday to early Saturday afternoon. Light southeast flow 
aloft...becoming moderate SW flow aloft late tonight and Saturday. 


Scattered-broken middle and high cloud tonight. Ceilings will lower to 3-5k feet as 
rain develops late morning/early afternoon ahead of the front. Southerly 
winds also picking up areawide during this period. The front will 
push through Puget Sound sound roughly 20z (1pm). 


Ksea...scattered clouds at 4-5k feet and broken at around 15-20k feet. North-NE winds 
tonight 4-8 kts...then southeast by Saturday morning. Winds switching southwesterly 
10-14 knots after 20z Sat. Dtm 


&& 


Marine...surface high pressure over the waters today will shift east 
tonight. A cold front will move through the coastal waters Sat 
morning and through the inland waters midday to early afternoon with 
Small Craft Advisory winds expected over all waters. High pressure 
will rebuild on Sunday. A weaker system will arrive later Monday or 
Monday night. 


A large swell train behind the cold front on Saturday will arrive 
along the Washington coast Saturday night and continue into Sunday. 
Swells in the 16 to 19 foot range are expected. High surf conditions 
are possible on the coast Saturday night into early Sunday. This is 
a razor clam dig weekend for Twin Harbors...copalis and Moclips 
beaches. Dtm 


&& 


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 all waters late tonight through Saturday 
night. 
Small Craft Advisory for rough Grays Harbor bar Saturday night.
