UPDATED COASTAL MARINE DISCUSSION AND MARINE ADVISORIES...

.SYNOPSIS...SHOWERY TODAY...BUT ANOTHER ROUND OF RAIN WILL ARRIVE
LATER FRIDAY...WITH MORE RAIN SATURDAY AM...THEN AGAIN ON SUNDAY.
UNSETTLED WEATHER CONTINUES INTO EARLY NEXT WEEK...BUT APPEARS MAY BE
RETURNING TO MILD AND DRY CONDITIONS BY NEXT WED OR THU.
&&

.SHORT TERM (TODAY THROUGH SATURDAY)...
WHAT REMAINS OF THE STRONG LOW THAT WAS OFFSHORE FROM OREGON LAST
NIGHT IS NOW APPROACHING VANCOUVER ISLAND. DECENTLY STRONG PRES
GRADIENTS REMAIN OVER THE REGION EARLY THIS AM...WITH BREEZY
CONDITIONS UNTIL DAYBREAK. WILL END ALL WIND ADVISORIES AND WARNINGS
BY 4 AM AS MOST WINDS WILL DROP BELOW CRITERIA BY THAT TIME. THIS
SAID...WILL SEE WEST TO SOUTHWEST WINDS GUST UP TO 45 MPH ALONG THE
COAST THIS AM. BUT WINDS WILL CONTINUE TO SUBSIDE TODAY.

FRONT STILL OVER THE CASCADES AT 3 AM...BUT WILL TAKE UNTIL 8 OR 9 AM
FOR TO FULL PUSH EAST OF THE CASCADES. WILL CONTINUE TO SEE RAIN OVER
THE CASCADES...BUT ELSEWHERE MOSTLY DRY EARLY THIS AM. THAT WILL
CHANGE AS COOLER AIR MASS ALOFT WILL PUSH INTO THE REGION
TODAY...WITH SHOWERS INCREASING THIS AM. IS ENOUGH INSTABILITY WITH
LIFTED INDICES RUNNING 0 TO -2...SO WILL KEEP A CHANCE OF
THUNDERSTORMS ACROSS THE REGION.  STILL THINK BEST THREAT WILL BE
OVER THE COAST RANGE AND WESTWARDS OVER THE COASTAL WATERS.

SHOWERS DECREASE LATER THIS EVENING. BUT MODELS HAVE CONSISTENTLY
ADVERTISING A LOW PRES ARRIVING FROM THE SW LATE FRI...INITIALLY
HEADING INTO FAR SW OREGON AND NW CALIF....THEN LIFTING NE INTO
CENTRAL OREGON. WILL CONTINUE WITH THIS TREND...WHICH WILL BRING
INCREASING RAIN TO NW OREGON FRI AFTERNOON AND FRI NIGHT.

ANOTHER FRONT WILL ARRIVE FROM THE WEST FRI NIGHT AND SAT AM...WITH
MORE RAIN. THIS WILL BE A MORE HEAVY RAIN EVENT...SIMILAR TO WHAT WAS
SEEN ON WED. SNOW LEVELS WILL BE DOWN...BETWEEN 3500 AND 4500 FT. SO
WILL SEE COUPLE OF INCHES OF SNOW ON PASSES ON SAT. ROCKEY.

.LONG TERM... SATURDAY NIGHT THROUGH WEDNESDAY...THE ACTIVE AND
UNSETTLED WEATHER PATTERN LOOKS TO CONTINUE OVER THE WEEKEND THROUGH
AT LEAST THE EARLY PART OF NEXT WEEK. EXPECT SHOWERS TO CONTINUE IN
THE POST-FRONTAL AIR MASS LATE SATURDAY THROUGH EARLY SUNDAY. SNOW
LEVELS WILL LOWER TO AROUND 3000 FT...PERHAPS AS LOW AS 2500 FT...SO
SEVERAL INCHES OF SNOW MAY FALL AT THE CASCADES PASSES AND LOWER IN
THE STEADIER AND HEAVIER SHOWERS. MODELS ARE IN REASONABLE AGREEMENT
THAT THE NEXT FRONT WILL APPROACH THE COAST LATER SUNDAY...WITH SOME
INDICATION OF A SURFACE LOW DEVELOPING AND TRACKING NORTH OVER THE
COASTAL WATERS. THIS MAY BRING ANOTHER COASTAL WIND EVENT ON
SUNDAY...BUT TOO SOON TO YET DISCERN IMPACTS. A BROAD UPPER TROUGH
THEN WILL PERSIST FOR THE FIRST PART OF NEXT WEEK TO MAINTAIN
ADDITIONAL SHOWERS. SNOW LEVELS REMAIN LOWER SO THESE WILL BE IN THE
FORM OF SNOW IN THE CASCADES...AND PERHAPS DOWN TO THE HIGHEST
ELEVATIONS OF THE FOOTHILLS AND COAST RANGE...AND RAIN ELSEWHERE
ACROSS THE AREA. MEANWHILE...EXPECT DAYTIME TEMPERATURES  TO REMAIN
BELOW SEASONAL NORMS FOR THE FIRST HALF OF NEXT WEEK.	CULLEN
&&

.AVIATION...PRIMARILY VFR CONDITIONS THIS MORNING ACROSS THE AREA.
RAIN IS MOVING OFF TO THE EAST. IN GENERAL WINDS ARE DECREASING
ACROSS THE AREA. THE ONLY EXCEPTION IS SOUTHWESTERLY WINDS WILL
CONTINUE TO GUST TO 40 TO 50 KT ALONG THE NORTH OREGON COAST FOR THE
NEXT FEW HOURS...THEN WINDS WILL START TO DECREASE AS WELL AFTER
14Z. GENERALLY VFR CONDITIONS CONTINUE ACROSS THE AREA THROUGH THE
DAY TODAY. WE ARE SEEING A BREAK IN THE RAIN EARLY THIS
MORNING...BUT WILL SEE SHOWERS MOVE BACK IN LATER THIS MORNING. MAY
SEE CIGS AND/OR VIS BRIEFLY DROP TO MVFR WITH HEAVIER SHOWERS. THERE
IS A CHANCE OF THUNDERSTORMS ACROSS THE AREA WITH SHOWERS LATER THIS
MORNING THROUGH THIS AFTERNOON...BUT CONFIDENCE ISN'T HIGH ENOUGH TO
INCLUDE IN TAFS AT THIS TIME.

KPDX AND APPROACHES...VFR CONDITIONS CONTINUE THROUGH THE DAY TODAY.
MAY SEE HEAVIER SHOWERS BRIEFLY BRING CIGS AND/OR VIS DOWN TO MVFR.
CHANCE OF A THUNDERSTORM MAINLY IN THE AFTERNOON. -MCCOY

&&

.MARINE...THE LOW PRESSURE SYSTEM THAT BROUGHT HURRICANE FORCE
WINDS AND SEAS PUSHING 30 FT YESTERDAY WILL CONTINUE TO MOVE NORTH
AND MAKE LANDFALL OVER BRITISH COLUMBIA THIS MORNING. A SECONDARY
LOW PRESSURE SYSTEM WILL MOVE ACROSS THE NORTHERN WATERS THIS
MORNING BRINGING STORM FORCE GUSTS TO 55 KT. AS SUCH...WILL
CONTINUE THE STORM WARNING FOR THE NORTHERN OUTER WATERS THROUGH
LATE THIS MORNING. WINDS OVER THE REST OF THE COASTAL WATERS
CONTINUE TO GUST TO AROUND 40 TO 45 KT EARLY THIS MORNING SO WILL
MAINTAIN THE GALE WARNING THROUGH LATE THIS MORNING BUT SUSPECT WE
MAY BE ABLE TO END IT OVER THE CENTRAL OREGON WATERS A FEW HOURS
EARLY. WINDS WILL QUICKLY FALL BELOW GALES THIS AFTERNOON WITH
MARGINAL ADVISORY GUSTS TO 25 KT POSSIBLE TONIGHT. THE NEXT
FRONTAL SYSTEM WILL APPROACH THE WATERS ON SATURDAY WITH ANOTHER
ROUND OF SOLID GALES LIKELY. THE ACTIVE WEATHER PATTERN CONTINUES
THROUGH AT LEAST WEDNESDAY.

STRONG WINDS CONTINUE TO PRODUCE VERY LARGE...STEEP...AND
DANGEROUS SEAS EARLY THIS MORNING WITH OFFSHORE BUOYS REPORTING
SIGNIFICANT WAVE HEIGHTS IN THE MID TO UPPER 20S AND OCCASIONALLY
REACHING 30 FT. SEAS WILL REMAIN ABOVE 20 FT THROUGH LATE THIS
MORNING. SEAS SHOULD SUBSIDE INTO THE MID TO UPPER TEENS THIS
AFTERNOON AS THE WINDS DROP OFF BEHIND THE SECONDARY LOW AND COULD
BRIEFLY FALL BELOW 10 FT ON FRIDAY. SEAS WILL BUILD BACK INTO THE
MID TEENS ON SATURDAY AND COULD APPROACH 20 FT SUNDAY AFTERNOON.

WITH REGARDS TO THE HIGH SURF...SEAS CONTINUE TO HAVE A DOMINATE
WAVE DIRECTION OUT OF THE SOUTH TO SOUTHWEST EARLY THIS MORNING.
THIS WILL YIELD A LARGE ANGLE OF INCIDENCE WITH RESPECT TO THE
COAST. SEAS JUST OFF THE CENTRAL OREGON COAST ARE CURRENTLY
AROUND 20 FT WITH A DOMINATE PERIOD OF 14 SECONDS SO HIGH SURF
IMPACTS WILL BE MINIMAL. HOWEVER...SEAS JUST OFF THE NORTHERN
OREGON AND SOUTH WASHINGTON COAST REMAIN IN THE MID TO UPPER 20S
WITH A DOMINATE PERIOD OF 14. THIS COULD PRODUCE MINOR BEACH
EROSION SO WILL REPLACE THE HIGH SURF WARNING WITH A HIGH SURF
ADVISORY TILL NOON. SEAS ARE FORECASTED TO FALL BELOW 20 FT THIS
AFTERNOON SO ADDITIONAL HIGH SURF IMPACTS SHOULD BE MINIMAL.

FINALLY...WATER LEVELS AT ASTORIA AND SOUTH BEACH HAVE FALLEN
BELOW 10 FT EARLY THIS MORNING AND NOT EXPECTED TO RISE ABOVE 11
FT THROUGH THE WEEKEND SO COASTAL FLOODING FOR THE NORTH AND
CENTRAL OREGON COAST REMAINS MINIMAL. WATER LEVELS AT TOKE POINT
PEAKED NEAR 13.4 FT EARLY THIS MORNING...BUT HAVE FALLEN TO
AROUND 10.7 FT AS OF 4 AM AND WILL CONTINUE TO FALL OVER THE NEXT
SEVERAL HOURS. WATER LEVELS MAY RISE ABOVE 11 FT WITH THE HIGH
TIDE THIS AFTERNOON AND PEAK NEAR 11.5 FT AROUND 2 PM SO WILL
ISSUE A COASTAL FLOOD ADVISORY FOR THE SOUTH WASHINGTON COAST
SURROUNDING THE HIGH TIDE. ADDITIONAL ROUNDS OF COASTAL FLOODING
OVER PORTIONS OF THE SOUTH WASHINGTON COAST MAY OCCUR THROUGH THE
WEEKEND DURING THE HIGH TIDES WITH WATER LEVELS APPROACHING 11 FT.
WILL NEED TO EVALUATE THE TIDAL ANOMALIES OVER THE NEXT SEVERAL
SHIFTS TO DETERMINE IF ADDITIONAL COASTAL FLOOD ADVISORIES ARE
WARRANTED. /64
