AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TIYAN GU
609 AM CHST MON NOV 23 2009

.SYNOPSIS...
TD 26W STILL ABOUT 460 SSE OF GUAM...AND CLOUDINESS ASSOCIATED WITH
IT HAS DECREASED DRAMATICALLY IN THE LAST 24 HR. MODERATE TO FRESH
TRADES AND ISOLATED SHOWERS ARE PRESENT ACROSS THE MARIANAS.

&&

.DISCUSSION...
STILL A TON OF UNCERTAINTY REGARDING THE FUTURE TRACK/INTENSITY
OF TD 26W. ITS CLOUD SIGNATURE HAS GREATLY DECLINED SINCE SUNDAY
AFTERNOON AND THE CONVECTIVE EMPHASIS SEEMS TO BE SHIFTING EAST
TOWARD CHUUK...THOUGH PRESSURE IS NOT FALLING THERE. CURRENT
FORECAST HAS TD 26W TRACKING SAFELY SOUTH OF GUAM ON WEDNESDAY AND
THURSDAY...WHICH MIGHT RESULT IN SOME GUSTY WINDS AND HEAVY
SHOWERS FOR THE MARIANAS. BUT THE MODELS ARE IN POOR AGREEMENT ON
26W...WITH THE UKMET/ECMWF KEEPING 26W WELL SOUTH...THE NOGAPS
TRACKING IT FURTHER NORTH...AND THE GFS TAKING IT PRACTICALLY OVER
GUAM. SO HAVE STAYED WITH THE CURRENT SET OF GRIDS...WHICH WOULD
STILL VERIFY WELL IF TD 26W FOLLOWS THE CURRENT TRACK FORECAST.
OF COURSE...IF 26W DECIDES TO TAKE THE GFS ROUTE...MAJOR CHANGES
WOULD HAVE TO BE MADE TO THE MARIANAS FORECAST.

&&

.MARINE/SURF...
WINDS HAVE DROPPED OFF BELOW SCA LIMITS AND SEAS HAVE FALLEN TO 9
FT IN GUAM/ROTA WATERS. BUT SEAS STILL EXPECTED TO BE 10 FT IN
TINIAN/SAIPAN WATERS...SO HAVE A SCA FOR HAZ SEAS UP THERE THE
NEXT 2 DAYS. STILL HOLDING SURF JUST BELOW HAZARDOUS LEVELS...BUT
NEEDS TO BE CLOSELY WATCHED...ESPECIALLY TINIAN AND SAIPAN.

&&

.EASTERN MICRONESIA...
A WEAK RIDGE BETWEEN 26W AND A TRADE-WIND DISTURBANCE EAST OF THE
MARSHALLS WILL ALLOW FAVORABLE WEATHER CONDITIONS TO PREVAIL AT
KOSRAE THROUGH MIDWEEK. RIDGING WILL EASE WEST OVER POHNPEI ON
TUESDAY IMPROVING WEATHER CONDITIONS THERE. THE TRADE DISTURBANCE
WILL BRING SCATTERED SHOWERS TO MAJURO THROUGH MIDWEEK BEFORE
MOVING WEST LATER ON.

&&

.WESTERN MICRONESIA...
CONVERGENT WINDS FEEDING INTO TROPICAL DEPRESSION 26W WILL CONTINUE
TO GENERATE NUMEROUS SHOWERS OVER CHUUK TODAY AND TONIGHT. ADDITIONAL
2 TO 4 INCHES OF RAIN AND WINDS GUSTS TO 30 KT ARE POSSIBLE THROUGH
THIS EVENING. AS 26W PULLS NORTH AND WEST...WEAK RIDGING WILL BUILD
WESTWARD OVER CHUUK BY MIDWEEK USHERING IN MORE FAVORABLE WEATHER
CONDITIONS. WEATHER OVER YAP/KOROR WILL GENERALLY REMAIN PLEASANT
THE FIRST COUPLE DAYS. WILL WATCH CLOSELY FOR THE FORMATION OF A
MONSOON TAIL ASSOCIATED WITH 26W THOUGH...WHICH COULD BRING SCATTERED
SHOWERS TO BOTH LOCATIONS LATER IN THE WEEK.

FRESH TO STRONG SOUTHERLY WINDS ASSOCIATED WITH 26W HAVE PRODUCED
LARGE SWELL AND WIND WAVES THAT HAVE ARRIVED IN CHUUK STATE. LATEST
WW3 MODEL GUIDANCE SUGGEST SURF HEIGHTS OF ADVISORY CRITERIA THROUGH
MIDWEEK. A HIGH SURF ADVISORY FOR SOUTH AND WEST EXPOSURES OF CHUUK
REMAINS IN EFFECT ACCORDINGLY.

&&

.GUM WATCHES/WARNINGS/ADVISORIES...
GU...NONE.
MARIANAS WATERS...SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS UNTIL
     6 AM CHST WEDNESDAY FOR PMZ153-154.

...TROPICAL DEPRESSION 26W AFFECTING CHUUK AND YAP STATES...

AT 700 AM CHST TROPICAL DEPRESSION 26W WAS LOCATED NEAR 8N148E. THIS
IS ABOUT 280 MILES WEST OF CHUUK...95 MILES WEST-NORTHWEST OF
PULUWAT AND 50 MILES EAST-NORTHEAST OF SATAWAL. IT HAS BEEN DRIFTING
SLOWLY WEST-NORTHWESTWARD WITH MAXIMUM SUSTAINED WINDS OF 35 MPH.
FOR MORE INFORMATION...SEE BULLETINS ISSUED BY THE JTWC UNDER WMO
HEADER WTPN21 PGTW...AND ADVISORIES ISSUED BY THE NATIONAL WEATHER
SERVICE UNDER WMO HEADER WTPQ31 PGUM.

FOR CHUUK...PULUWAT...ULUL AND NEARBY ISLANDS AS WELL AS SATAWAL IN
YAP STATE...PERIODS OF HEAVY SHOWERS AND ISOLATED THUNDERSTORMS ARE
LIKELY THROUGH TUESDAY. CHUUK HAS RECEIVED NEARLY 8 INCHES OF RAIN
OVER THE WEEKEND WITH SIMILAR AMOUNTS ON NEARBY ISLANDS. SUSTAINED
WINDS OF 15 TO 25 MPH WITH GUSTS TO 35 MPH IN HEAVIER SHOWERS ARE
ANTICIPATED AS TROPICAL DEPRESSION 26W CONTINUES TO GRADUALLY
INTENSIFY...PERHAPS BECOMING A TROPICAL STORM TONIGHT. ADDITIONAL
RAINFALL AMOUNTS OF 3 TO 6 INCHES ARE EXPECTED DURING THE NEXT 24
HOURS OVER CHUUK AND NEARBY ISLANDS AND ATOLLS. IF HIGH RAINFALL
RATE CONTINUES...ESPECIALLY WITH THE SLOW MOVEMENT OF
26W...LOCALIZED FLOODING AND MUD SLIDES MAY BE OF A CONCERN FOR
CHUUK.

IN ADDITION TO THE HEAVY RAINFALL...INCREASING WINDS ASSOCIATED WITH
TROPICAL DEPRESSION 26W WILL CAUSE SEAS TO AND SURF RISE TO
HAZARDOUS LEVELS.

RESIDENTS OF CHUUK AND YAP STATES ARE ADVISED TO CLOSELY MONITOR THE
LATEST ADVISORIES FROM THE NATIONAL WEATHER SERVICE AND LOCAL
EMERGENCY MANAGEMENT OFFICES ON TROPICAL DEPRESSION 26W.

THE NATIONAL WEATHER SERVICE WILL CONTINUE TO MONITOR THIS SYSTEM
CLOSELY AND UPDATE THIS STATEMENT...OR ISSUE WATCHES AND WARNINGS IF
NECESSARY.
