AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
940 AM PST MON NOV 16 2009

.SYNOPSIS...A VIGOROUS FRONTAL SYSTEM WILL AFFECT THE REGION THROUGH
TUESDAY. HEAVY RAIN WILL FALL IN THE OLYMPICS AND NORTH CASCADES.
THE HEAVY RAIN WILL SPREAD TO SOUTHWEST WASHINGTON LATER TODAY.
THERE WILL BE STRONG WINDS AT TIMES...WINDSPEEDS ARE LIKELY TO PEAK
AROUND DAYBREAK...EASE THROUGH THE DAY...AND THEN INCREASE AGAIN
TONIGHT AND TUESDAY. ANOTHER STRONG FRONTAL SYSTEM WILL ARRIVE
WEDNESDAY NIGHT AND THURSDAY.

&&

.SHORT TERM...THE TWO MAIN CONCERNS THIS MORNING ARE WINDS AND HEAVY
PRECIP. FIRST THE WINDS...PRESSURE GRADIENTS PEAKED AROUND 12Z WITH
WINDS ACROSS MOST AREAS STARTING TO EASE. SPOTTERS STILL REPORTING
GUSTS TO 50 MPH IN THE NORTH INTERIOR. COAST AND CENTRAL SOUND STILL
WINDY WITH SOUTHERLY WINDS 15-25 AND GUSTS TO 45 MPH. BASED ON NEW
12Z GUIDANCE WINDS WILL EASE FURTHER THIS AFTERNOON. UNTIL
THEN...WILL CONTINUE THE HIGH WIND WARNING AND WIND ADVISORIES FOR
THE AREA UNTIL NOON AS PLANNED.

HEAVY PRECIP...THE FOCUS FOR HEAVY RAIN THUS FAR HAS BEEN OVER THE
OLYMPIC PENINSULA. FREEZING LEVEL IS AROUND 6000 FT OFF THE KUIL
SOUNDING AND WESTPORT PROFILER...WITH SWLY UPSLOPE FLOW OVER 50KT.
SO FAR FLOODING OBSERVED ON THE SKOKOMISH RIVER IN MASON CO AND WILL
NEED TO WATCH THE SATSOP...BOGACHIEL AND ELWHA RIVERS. MAIN CONCERNS
FOR THE NORTH CASCADES ARE NOOKSACK...SKAGIT AND STILLAGUAMISH.
FLOOD WATCH REMAIN IN EFFECT FOR THESE AREAS.

AFTER A VERY BRIEF LULL...MORE HIGH WIND POSSIBLE LATE THIS EVENING
INTO TUE MORNING WITH THIS NEXT SYSTEM...ANOTHER 980 MB LOW SLIDES
NE INTO VANCOUVER ISLAND. HIGH WIND WATCH UP FOR ALL OF WESTERN WA
RIGHT NOW...BUT LOOKS LIKE THE STRONGEST WINDS WILL BE THE COAST AND
NORTH INTERIOR...WITH ADVISORY WINDS SEATTLE SOUTHWARD...SIMILAR TO
CURRENT CONDITIONS. WILL UPDATE FOR THE EVENING PACKAGE. 33

.LONG TERM...PREVIOUS DISCUSSION...THE NEXT FNTL SYS ARRIVES WED
NITE/EARLY THU...THE GFS DEEPENS THE ASSOCIATED SFC LOW INTO THE
970S AND TRACKS IT UP TO THE SRN TIP OF THE CHARLOTTES. THE
ASSOCIATED FRONT IS RATHER STRONG WITH ANOTHER FULL SSE GALE FOR
MOST OF THE MARINE AREAS WED AFTERNOON AND EVENING. THE FRONT MOVES
INLAND OVERNIGHT AND THU MORNING. THE GFS THEN DEEPENS A SECONDARY
SFC LOW ARND 992MB TO THE ORE COAST LATE THU...IT IS A 990MB CENTER
INTO ASTORIA IN THE WRFGFS. THE ECMWF IS SIMILAR...ALTHOUGH THE
SECONDARY LOW TRACKS FROM THE SRN ORE WATERS 12Z FRI TO ERN WA PM
FRI. ADDITIONAL SYSTEMS FOLLOW...ONE ON THE WEEKEND A STRONGER
SYSTEM MONDAY. THE GLOBAL MODELS ARE TRYING TO PUT THE WEST COAST
INTO THE MEAN RIDGE POSITION BY THIS TIME...AND BOTH THE GLOBAL
MODELS HAVE AN UPPER RIDGE ALONG THE WEST COAST BY THE MIDDLE OF
NEXT WEEK. 19

&&

.HYDROLOGY...PREVIOUS DISCUSSION...HEAVY RAIN IN THE OLYMPICS
OVERNIGHT AND AROUND MOUNT BAKER. VERY LITTLE PRECIP SO FAR AT
STEVENS OR SNOQUALMIE PASS...OR MT RAINIER FOR THAT MATTER. THE
BAROCLINIC ZONE IS LIKELY TO SAG SOUTH TODAY...SOUTHWEST WA MAY
RECEIVE HEAVY RAIN LATER TODAY. THE WRFGFS IS SHOWING AS MUCH AS
SEVEN INCHES IN THE WILLAPA HILLS AREA AND 2-4 FOR MT RAINIER...BUT
THE GREEN RIVER AREA AND THE CASCADES NORTH OF RAINIER UP THRU
SNOQUALMIE PASS CONTINUE TO HAVE ONLY VERY MODEST RAINFALL...AN INCH
OR TWO OVER THE NEXT 24HRS. SO...WHILE RIVERS IN THE CENTRAL
CASCADES WILL SEE RISES THE FOCUS OF PRECIPITATION IS ELSEWHERE AND
NO FLOODING IS EXPECTED ON THE GREEN RIVER.

THE HEAVIEST RAIN TOTALS FOR THIS FLOODING EVENT WILL BE IN THE
OLYMPICS AND THE NORTH CASCADES ESPECIALLY AROUND MT BAKER...AND THE
WILLAPA HILLS. THE CENTRAL CASCADES WILL RECEIVE JUST 1-2 INCHES OF
RAIN THRU TNGT. STEVENS AND SNOQUALMIE PASS WERE STILL BELOW
FREEZING AT 2AM WITH EASTERLY FLOW...BUT THE MILD STRONG SW FLOW
ALOFT WILL FINALLY OVERWHELM THAT COOL AIR...SO MOST OF THE PRECIP
SHUD BE RAIN TODAY.

A FLOOD WARNING HAS ALREADY BEEN ISSUED FOR THE SKOKOMISH RIVER IN
MASON COUNTY. OTHER RIVERS ON THE OLYMPIC PENINSULA ALSO FACE A
THREAT OF FLOODING...INCLUDING BUT NOT LIMITED TO THE SATSOP...
BOGACHIEL...ELWHA...AND DUNGENESS RIVERS.

FLOODING IN THE NORTH CASCADES RIVER BASINS IS ALSO A POSSIBILITY.
THE NOOKSACK RIVER IN WHATCOM COUNTY...WHICH FLOWS OFF THE SLOPES OF
MOUNT BAKER...IS AT HIGHEST RISK. RAINFALL AMOUNTS WILL BE HIGH
ENOUGH TO ALSO PUSH THE SKAGIT RIVER IN SKAGIT COUNTY AND THE
STILLAGUAMISH RIVER IN SNOHOMISH COUNTY TO NEAR FLOOD STAGE AS
WELL.

THERE IS ALSO A POSSIBILITY THAT THE CHEHALIS RIVER COULD BE ADDED
TO THE FLOOD WATCH LATER THIS MORNING.

AT THIS TIME NO FLOODING IS EXPECTED ON THE GREEN RIVER. 19/FELTON

&&

.AVIATION...STRONG SOUTHWEST FLOW ALOFT OVER WESTERN WASHINGTON WITH
A FRONTAL BAND EXTENDING SOUTHWEST FROM SOUTHWEST BRITISH COLUMBIA
ACROSS THE WASHINGTON OFFSHORE WATERS. A DEVELOPING SURFACE LOW WILL
MOVE INTO THE OFFSHORE WATERS LATE TODAY...TRAVEL NORTHEAST ALONG
THE FRONTAL BAND AND CROSS VANCOUVER ISLAND LATE TONIGHT. THE
TRAILING OCCLUDED FRONT WILL MOVE THROUGH WESTERN WASHINGTON TUESDAY
MORNING.

STRONG LOW LEVEL WINDS WILL CONTINUE THROUGH TONIGHT. LOCAL WIND
PROFILER AT WESTPORT SHOWS 50-60 KT SW WINDS ABOVE 2500 FEET. EXPECT
WINDS TO INCREASE TONIGHT AS THE SURFACE LOW MOVES UP THE FRONT.
CIGS MAINLY VFR THROUGH PUGET SOUND...BUT WITH RAIN CONTINUING COULD
LOWER TO MVFR AT TIMES. CIGS LOWER TO MVFR OVER PARTS OF THE NW
INTERIOR AND OUT TOWARD THE COAST.

KSEA...CIGS STILL RUNNING VFR THIS MORNING. WILL KEEP THEM THERE OR
AT MVFR AT THE LOWEST THROUGH THIS AFTERNOON...SINCE NO SPECIFIC
APPROACHING WAVE IS CLOSE ENOUGH TO REACH THE AREA THROUGH THIS
AFTERNOON. OTHERWISE THE MAIN PROBLEM ARE THE STRONG LOW LEVEL
WINDS. NO SIGNIFICANT CHANGE SEEN FROM CURRENT WINDS...S 50-60 KT
ABOVE 3000 FEET. COULD SEE SOME LOW LEVEL WIND SHEAR AT TIMES WITH
40 KT WINDS WITHIN 2000 FEET OF THE GROUND. KAM

&&

.MARINE...A VIGOROUS FRONTAL SYSTEM WILL CONTINUE TO AFFECT THE
FORECAST AREA THROUGH TUESDAY. A FRONTAL BAND EXTENDS SOUTHWEST FROM
SOUTHWEST BRITISH COLUMBIA ACROSS THE OFFSHORE WATERS. THIS FEATURE
WILL CONTINUE TO PRODUCE GALE TO STORM FORCE WINDS OVER THE COASTAL
WATERS...ENTRANCES TO THE STRAIT OF JUAN DE FUCA...AND NORTHERN
INLAND WATERS THIS MORNING. STORM WARNINGS WILL REMAIN IN EFFECT
THIS MORNING FOR THOSE MARINE ZONES...WITH GALE WARNINGS FOR THE
ADMIRALTY INLET AND PUGET SOUND AND HOOD CANAL.

LULL IN ACTIVITY TODAY IN-BETWEEN WAVES. PRESSURE GRADIENTS HAVE
EASED A LITTLE...SO HAVE DROPPED THE STORM WARNING FOR THE AREA.
HOWEVER WITH THE NEXT WAVE REACHING THE COAST THIS EVENING...HAVE
ISSUED A STORM WARNING FOR THE COAST AND WEST ENTRANCE TO HANDLE THE
INCOMING LOW. WILL HOLD OFF ON THE INTERIOR ZONES WITH AN EYE ON AN
UPGRADE THIS AFTERNOON.

COASTAL FLOODING IS A POSSIBILITY WITH THE HIGH TIDE THAT WILL OCCUR
MIDDAY TUESDAY. LOW ATMOSPHERIC PRESSURE...PERSISTENT STRONG SOUTH
WINDS ALONG THE COAST...AND WAVES OF 20 FT COULD RESULT IN TIDAL
ANOMALIES OF 2 TO 3 FT. THIS COULD CAUSE SOME FLOODING IF THE STORM
TIMING LINES UP WITH THE MIDDAY TUESDAY HIGH TIDE. A COASTAL FLOOD
WATCH IS IN EFFECT FOR TUESDAY ALONG THE CENTRAL COAST.

ANOTHER VIGOROUS FRONTAL SYSTEM WILL AFFECT THE FORECAST AREA
WEDNESDAY THROUGH EARLY THURSDAY...PROBABLY PRODUCING ANOTHER ROUND
OF GALES FOR MUCH OF THE MARINE FORECAST AREA. MODELS DIFFER
CONSIDERABLY FOR THURSDAY AND BEYOND BUT APPEARS THAT AN ACTIVE
WEATHER PATTERN WILL CONTINUE. MCDONNAL

&&

.AVALANCHE...RECENT LARGE AMOUNTS OF WEAK SNOW LAYERS RECEIVED LAST
WEEK HAVE BEEN INCREASINGLY LOADED OR WEAKENED BY EITHER HEAVY
...DENSER SNOW OR RAIN DURING THE PAST 24 HOURS. ALTHOUGH POOR
VISIBILITY AND VERY DIFFICULT TRAVEL CONDITIONS HAVE PREVENTED
DIRECT OBSERVATIONS...GENERALLY HIGH AVALANCHE DANGER IN THE NORTH
CASCADES AND OLYMPICS HAS BEEN THE RESULT. ALMOST 5 INCHES OF RAIN
HAVE BEEN RECORDED NEAR MT BAKER DURING THE PAST 24 HOURS WITH
ANOTHER 3 TO 5 INCHES LIKELY BEFORE TUESDAY MORNING. WITH VERY
WET...AND WINDY CONDITIONS EXPECTED TO CONTINUE IN THE NORTH AND
SPREAD SOUTHWARD ON MONDAY WITH ONLY A VERY SLOW COOLING TREND
...CURRENT HIGH DANGER SHOULD PERSIST IN THE NORTH AND OLYMPICS WITH
MORE MODEST THOUGH STILL SIGNIFICANT DANGER INCREASES EXPECTED
ELSEWHERE. EARLY SEASON BACK COUNTRY TRAVELERS SHOULD MINIMIZE THEIR
TIME IN AND EXPOSURE TO STEEPER AVALANCHE TERRAIN UNTIL THE RECENT
SNOWPACK BEGINS TO STABILIZE THROUGH DRAMATIC COOLING AND MORE
SHOWERY PRECIPITATION EXPECTED ON TUESDAY. SEE NWAC.US FOR DETAILS.
