NWS Seattle, WA wrote its last area forecast discussion before this river flood warning went out at Feb 21, 8:55 PM PST, 28 minutes earlier.

Area forecast discussion, Feb 21, 8:55 PM PST, 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
855 PM PST TUE FEB 21 2012

.SYNOPSIS...MOIST ONSHORE FLOW WILL BRING RAIN AND MILD TEMPERATURES
TONIGHT. A COLD FRONT WILL SAG SOUTH THROUGH THE AREA WEDNESDAY WITH
RAIN CHANGING TO SHOWERS. HIGH PRESSURE WILL GIVE DRY WEATHER
THURSDAY. A FRONTAL SYSTEM WILL BRING MORE RAIN FRIDAY. A COLD UPPER
TROUGH WILL SETTLE OVER THE AREA NEXT WEEKEND INTRODUCING THE CHANCE
FOR LOWLAND SNOW.

&&

.SHORT TERM...STRONG MOIST ONSHORE FLOW WILL CONTINUE TONIGHT.
COMBINED WITH HIGH SNOW LEVELS...THIS WILL BRING FLOODING RAINS TO
THE MOUNTAINS. THE SEATTLE METRO AREA WILL CONTINUE TO BE SOMEWHAT
SHADOWED IN WESTERLY FLOW ALOFT HOWEVER. SNOW LEVELS HAVE RISEN TO
5000 OR 6000 FEET CENTRAL CASCADES AND AROUND 4500 FEET NORTH
CASCADES. SNOW STOPPED ACCUMULATING AT MOUNT BAKER SEVERAL HOURS AGO
AND THE HEAVY SNOW WARNING FOR TONIGHT HAS BEEN CANCELED THERE. THE
HEAVY RAINS HAVE ALSO CREATED AN INCREASED THREAT FOR LANDSLIDES...
MAINLY NEAR THE CASCADE FOOTHILLS. A SPECIAL WEATHER STATEMENT HAS
BEEN ISSUED TO ADDRESS THIS THREAT.

THE BAROCLINIC BAND DRAPED ACROSS THE AREA TONIGHT WILL SAG SOUTH AS
A COLD FRONT ON WEDNESDAY WITH RAIN CHANGING TO SHOWERS FROM NORTH
TO SOUTH AND LOWERING SNOW LEVELS. SNOW LEVELS WILL FALL BELOW PASS
LEVEL BY AFTERNOON AND THERE SHOULD SEVERAL INCHES OF ACCUMULATIONS
BY EVENING. A WINTER WEATHER ADVISORY IS IN EFFECT FOR THE MOUNTAINS
ABOVE 2500 FEET TO COVER THIS.

BREEZY TO WINDY CONDITIONS WILL CONTINUE TONIGHT AND WEDNESDAY WITH
STRONG ONSHORE FLOW...BUT PROBABLY BELOW WIND ADVISORY LEVELS ALL
AREAS. AN UPPER RIDGE WILL BUILD OVER THE AREA WEDNESDAY NIGHT AND
THURSDAY BRINGING DRIER WEATHER AND MAYBE EVEN SOME SUNSHINE ON
THURSDAY. A COLDER FRONTAL SYSTEM WILL BRING RAIN AND MOUNTAIN SNOW
FRIDAY. SCHNEIDER

.LONG TERM...PREVIOUS DISCUSSION...A COLDER WEATHER PATTERN WILL
BECOME ESTABLISHED OVER THE PAC NW DURING THIS PERIOD. ANTICIPATE
THE SNOW LEVEL TO FALL TO NEAR SEA LEVEL BY LATE IN THE PERIOD. AT
THIS TIME...IT DID NOT APPEAR THAT SIGNIFICANT SNOW WILL FALL ON
THE LOWLANDS. 05

&&

.HYDROLOGY...PREVIOUS DISCUSSION...MANY PLACES RECEIVED 1-2 INCHES
OF RAIN IN THE 24-HR PERIOD ENDING AT 2 PM PST TODAY. HOWEVER THE
CASCADES RECEIVED QUITE A BIT MORE OR 2.5 TO 4.5 INCHES OF
PRECIP...ALTHOUGH SOME OF THIS FELL IN THE FORM OF SNOW ABOVE THE 4K
FT LEVEL. ANTICIPATE ANOTHER 1 TO 3 INCHES OF RAIN IN THE MOUNTAINS
BELOW THE SNOW LEVEL TONIGHT...WITH THE HEAVIEST AMOUNTS OCCURRING
IN THE CASCADES.

A MOIST PLUME OF MOISTURE WILL CONTINUE TO BE AIMED AT WRN WA
THROUGH MUCH OF TONIGHT. THIS MOISTURE PLUME WAS BEING AIDED BY 180
KNOT PLUS JET. STRONG OROGRAPHIC LIFT WILL HELP TO ENHANCE PRECIP
RATES ON THE W FACING SLOPES OF THE CASCADES ESPECIALLY.

LOOK FOR THE RAIN RATES TO SHUT DOWN OR MARKEDLY DECREASE BEHIND THE
COLD FRONT THAT WILL SWEEP ACROSS THE AREA LATE TONIGHT OR EARLY
WEDNESDAY. THE SNOW LEVEL WILL ALSO FALL TO NEAR 2500 FEET BY LATE
WED MORNING. THUS LOOK FOR THE RAIN TO CHANGE OVER TO SNOW IN THE
MOUNTAINS ABOVE THIS LEVEL.

ALTHOUGH THE RAIN WILL DECREASE WED MORNING...AREA RIVERS WILL
CONTINUE TO RUN HIGH...WITH FLOODING CONTINUING ON SOME RIVERS. IN
FACT...SOME RIVERS WILL NOT CREST UNTIL SOMETIME WED. ANTICIPATE THE
RIVERS TO START RECEDING WED AFTERNOON OR NIGHT. THE RISK OF
FLOODING SHOULD COME TO AN END BY LATE THU.

BEYOND THU...A COLDER PATTERN WILL BECOME ESTABLISHED OVER THE
NW...THUS FLOODING IS NOT EXPECTED FRI THROUGH THE MIDDLE OF NEXT
WEEK. 05

&&

.AVALANCHE...THE CURRENT HEAVY LOADING OF WET HEAVY SNOW OR RAIN
THAT BEGAN EARLY TUESDAY AT RISING FREEZING LEVELS HAS CAUSED A
SIGNIFICANT INCREASE IN THE AVALANCHE DANGER. THE HEAVY
PRECIPITATION IS LOADING THE 2 TO 4 FEET OF SNOWFALL THAT HAS
ACCUMULATED SINCE LATE FRIDAY. CONTINUED WARMING AND FURTHER HEAVY
PRECIPITATION RATES OVERNIGHT AND EARLY WEDNESDAY SHOULD CAUSE LARGE
TO VERY LARGE AVALANCHES. A WIDESPREAD AVALANCHE CYCLE BEGAN NEAR
NOON TODAY IN THE SNOQUALMIE PASS AREA, REPORTED BY PROFESSIONAL
PATROLLED...CONFIRMING THESE DANGEROUS CONDITIONS.

AN AVALANCHE WARNING HAS BEEN ISSUED FOR EXTREME AVALANCHE DANGER ON
TUESDAY NEAR AND WEST OF THE CREST AND A HIGH DANGER ELSEWHERE. THE
NWAC RECOMMENDS AVOIDING ALL AVALANCHE TERRAIN ON TUESDAY IN THE
OLYMPICS AND NEAR AND WEST OF THE CREST WITH TRAVEL IN AVALANCHE
TERRAIN NOT RECOMMENDED ELSEWHERE.

...HEAVY RAINFALL SINCE THIS MORNING THROUGH TOMORROW MORNING WILL LEAD TO
INCREASE RISK OF LANDSLIDES THE PORTIONS OF WESTERN WASHINGTON
INCLUDED IN THIS SPECIAL WEATHER STATEMENT...

RAINFALL OF 2 TO 6 INCHES INCHES OVER THE PAST 24 HAS INCREASED
SOIL MOISTURE TO MODERATE LEVELS ACROSS WESTERN WASHINGTON EAST OF
THE PUGET SOUND. HEAVY RAINFALL OF AN ADDITIONAL 1 TO 3 INCHES IN

RANGE. ADDING RAINFALL FROM TODAY AND WHAT IS STILL TO COME
OVERNIGHT...THE ESTIMATED WASHINGTON LANDSLIDE RISK LEVEL IS
MODERATE. AT THIS THREAT LEVEL...SCATTERED LANDSLIDES ARE POSSIBLE IN
THE AREAS SPECIFIED IN THIS STATEMENT. THIS THREAT LEVEL IS ESTIMATED USING
CURRENT RAINFALL INFORMATION THAT IS NOT IN EITHER THE USGS OR WA
DNR-NWS INDEXES.

WITH AN ELEVATED LANDSLIDE RISK...RAINFALL INDUCED LANDSLIDES ARE
POSSIBLE DURING BURSTS OF INTENSE RAINFALL OR WHEN THERE IS HEAVY
RAINFALL OVER A PERIOD OF A DAY OR TWO AS NOTED IN THE FORECAST
ELEVATED RISK LEVEL. A GRADUALLY DIMINISHING RISK OF LANDSLIDES
WILL CONTINUE FOR SEVERAL DAYS AFTER THE RAIN ENDS. AREAS MOST
SUSCEPTIBLE TO LANDSLIDES UNDER THESE CONDITIONS ARE STEEP COASTAL
BLUFFS AND OTHER STEEP HILLSIDES.
