EVENT...VERY LARGE SYSTEM COMING INTO THE PACIFIC NW
.
SATELLITE ANALYSIS AND TRENDS...STRONG UPPER LOW NOW NEAR 43N/140W
CONTINUES TO PULL NEWD WITH ITS VERY EXPANSIVE MOISTURE PLUME IN TOW AS
EVIDENT FROM WV IMAGERY PULLING MOISTURE FROM THE TROPICAL WATERS SW
OF HAWAII. MULTIPLE SMALL S/WV'S ARE SEEN COMING AROUND THE UPPER LOW
ITSELF WHILE ALONG THE MOISTURE PLUME..NEXT SYSTEM DROPPING SWD IN THE
CENTRAL PACIFIC IS BEGINNING TO PILE UP MOISTURE AHEAD OF IT WHERE S/WV
IS FORMING BETWEEN 155-160W. AMSU PASS AT 1118Z SHOWED AN INCREDIBLE
PW PLUME THAT NEARLY REACHES THE ITCZ SW OF HAWAII AT 15N/175W. PW
VALUES WERE AT 2-2.3" IN THE CENTER OF THE PLUME AND THIS AXIS OF
HIGHEST MOISTURE STRETCHED FROM JUST NE OF HAWAII TO THE NW OR/SW WA
COAST. INSTANTANEOUS AREAL AVG RAIN RATES WITHIN THE PLUME SHOWED RATES
OF .1-.2"/HR WITH EMBEDDED PIXELS OF .25" COMMON. OVER WRN WA WHERE THE
AMPLE MOISTURE IS BEING LIFTED BY THE NRN CASCADES..RATES WERE AS HIGH
AS .5"/HR..MOSTLY AFFECTING KING AND PIERCE COUNTIES BUT ALSO WITH RATES
OF .2-.4"/HR OVER THURSTON/LEWIS COUNTIES. 11Z STLT WINDS SHOWED FAIRLY
GOOD PARALLEL ALIGNMENT WITH THE MOISTURE PLUME FROM THROUGHOUT MOST
OF THE ATMOSPHERE WHICH IS WHY MOISTURE TRANSPORT FROM THE TROPICAL
ERN PACIFIC IS SO GOOD RIGHT NOW. 160 KT JET IS SEEN ON WV IMAGERY
PUSHING INTO VANCOUVER ISLAND WITH STLT WINDS SHOWING ADDITIONAL 140
KT JET MAXES NEAR 138W AND 145W. WITH AREA VWP DATA SHOWING CONSISTENT
60KT WINDS AT 850 DIRECTING THE RICH TROPICAL MOISTURE INTO CASCADES
AND COASTAL MTNS..SEVERAL AREAS IN NW OR W WA COULD SEE AMOUNTS OF 1-2"
OVER THE NEXT 3-6 HOURS WITH THE MOST FAVORED ORAGRAPHIC AREAS RECEIVING
HIGHER AMOUNTS. HYDROETIMATOR SHOWED A FEW AREAS IN SNOHOMISH AND KING
COUNTIES THAT RECIEVED OVER 2" IN THE PAST 3 HRS THOUGH IN SUCH RUGGED
TERRAIN ITS HARD TO TELL HOW ACCURATE THESE ESTIMATES ACTUALLY ARE. SEE
