Severe Weather Alert Descriptions

 Areal Flood Warning  Statement as of 3:43 PM PDT on April 23, 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.

* A warm front will spread rain to the Oso area tonight followed by
showers on Thursday as a cold front passes through. Up to 1 inch
of rain may fall over this period which may result in 0.5 foot
rise on the North Fork of the stillaguamish river from near
Arlington eastward to the slide.

* At 330 PM PDT Wednesday... the North Fork of the stillaguamish
river near Arlington was at 4.61 feet or 2825 cfs. The North Fork
of the stillaguamish near Oso was at 216.4 feet... or 1830 cfs.

* At 315 PM PDT Wednesday... the elevation of the slide pool to the
east of the sr 530 landslide was 282.33 feet. 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 
830 PM PDT Wednesday Apr 23 2014 


Synopsis...a warm front will bring rain tonight. A cold front will 
move inland Thursday morning. An upper level trough digging into the 
Pacific northwest on Friday will keep scattered showers in the 
forecast. A third frontal system will bring another round of more 
organized rainfall to the area Saturday night into Sunday morning. 


&& 


Short term...rain has spread across the area from the southwest 
this evening as a warm front moves through. A trailing cold front 
will move inland Thursday morning with rain changing to showers. An 
upper trough will settle over the region Friday. This will keep a 
chance of showers in the forecast but there should also be sunshine 
at times. Another frontal system will approach from the west on 
Saturday...with rain reaching the coast in the afternoon and 
spreading into the interior by evening. Schneider 


Long term...previous discussion...moist westerly flow will keep a 
chance of showers in the forecast on Sunday. Models show a weak 
upper level disturbance tracking through western Washington for scattered 
activity. Showers will decrease Sun night as a ridge start to build 
over the Pacific northwest. 


A weak warm front may clip western Washington on Monday for a chance 
of rain. The models then strengthen the ridge over the Pacific northwest Tuesday 
and Wednesday for warmer and drier weather. The forecast leans toward the 
European model (ecmwf) solution which shows an 500 mb 580 ridge over Washington. The low level 
flow is also turning offshore and we should see highs in the upper 
60s to 70s if this pans out. 33 


&& 


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


The exception remains 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 8 PM...the North Fork of the stillaguamish near Arlington was 
at 4.6 feet...or 2810 cfs. The North Fork of the stillaguamish river 
near Oso was at 216.4 feet at 1800 cfs. The pool east of the slide was 
282.2 feet this evening. 


A warm front will bring rain tonight...followed by a cold front 
Thursday morning. This system will bring around 1.00 inch of 
rainfall to the area through Thursday afternoon. This is expected to 
produce rises on the stillaguamish river beginning this evening 
through Thursday. The latest hydrograph shows the stillaguamish near 
Arlington cresting late Thursday morning around 5 feet. 


&& 


Avalanche...previous discussion...further heavy snow and then 
potential rain should be seen in the Montana Rainier to Montana Hood area 
Wednesday night and Thursday morning. This is very likely to cause 
wet loose...storm slab and wind slab avalanche conditions in this 
area. An avalanche warning will be issued for the Montana Rainier to Montana 
Hood area for Wednesday night and Thursday morning. Back country 
travel in avalanche terrain is this area is not recommended 
Wednesday night and Thursday morning. 


Significant snow and avalanche conditions are also expected in other 
areas but that are slightly less than warning criteria. Avalanches 
are also likely in these other areas as well. 


Please visit nwac.US for details. Gkf 


&& 


Aviation...a warm front will lift northward through western 
Washington late tonight followed by a cold front late morning 
Thursday. Upper flow will turn southwesterly. Widespread rain with 
low MVFR and areas of IFR can be expected with the warm front. The 
rain will turn to showers midday Thursday with ceilings lifting to 
mostly VFR. Surface winds will become gusty from the south and 
southwest Thursday morning as an associated surface low moves into 
Vancouver Island. 




Ksea...MVFR ceilings 2-3k feet overnight. Rain will reduce visibility 
to 3sm at times tonight. Southeast wind 7 to 12 knots...shifting to 
southerly after 09z. Winds will rise from the S-SW after 
12z...gusting to 20-25 kts at times into Thursday afternoon. 


&& 


Marine...winds over the coastal waters are starting to rise over 
the past hour as a warm front edges closer. Gale warnings remain in 
effect for the coastal waters overnight and Thursday...with small 
craft advisories all other waters. Strong pressure rises will follow 
a surface low as it lifts into Vancouver Island early Thursday. This 
will lead to some gusty south or southwest winds over the inland 
waters much of Thursday. Winds could briefly approach gale force in 
parts of Puget Sound sound Thursday morning. 


After a lull in the action Friday...another front will spread Small 
Craft Advisory strength winds over the area Saturday night. 27 


&& 


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...Gale Warning coastal waters. 
Small Craft Advisory all other waters. 
Small Craft Advisory for rough Grays Harbor bar.
