AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TIYAN GU
529 AM CHST WED APR 1 2015

.SYNOPSIS...
SUPER TYPHOON MAYSAK HAS PASSED TO THE SOUTH OF GUAM AND IS
NEARING ITS CLOSEST POINT OF APPROACH TO YAP. OUTERMOST SHOWER
BAND ON THE NORTHEAST SIDE OF MAYSAK HAS BEEN TRAINING OVER
GUAM...BUT BAND HAS BECOME BROKEN AS SHOWER COVERAGE WITHIN THE
BAND DECREASES. SATELLITE IMAGERY SHOWS QUIET WEATHER EAST OF
MAYSAK ALL THE WAY TO EASTERN MICRONESIA...WHERE THERE IS A LARGE
AREA OF CONVECTION ASSOCIATED WITH A TROPICAL DISTURBANCE. LATEST
ASCAT REVEALS A MODEST SURFACE CIRCULATION CENTERED SOUTH OF
KOSRAE NEAR 1N165E.

&&

.DISCUSSION...
MODEL AND SATELLITE TRENDS ARE ALL IN AGREEMENT THAT A DRIER
TRADE-WIND PATTERN WILL ASSERT ITSELF BY THIS WEEKEND. WEATHER
GRIDS STILL CARRY SOME RESIDUAL CLOUDINESS UNTIL FRIDAY
MORNING...WHEN ZONE OF TRADE-WIND CONVERGENCE FINALLY SHIFTS TO
THE EAST OF THE MARIANAS. MODEL SOLUTIONS CONTINUE TO DIFFER AS
WELL AS CHANGE REGARDING THE FUTURE TRACK AND EVOLUTION OF THE
TROPICAL DISTURBANCE CENTERED NEAR KOSRAE. UNTIL MODEL SOLUTIONS
CONVERGE TOWARD A WETTER FORECAST SCENARIO FOR THE FORECAST
ZONES...WILL MAINTAIN A DRY BIAS FOR THE EXTENDED PORTION OF THE
FORECAST.

&&

.MARINE...
IPAN BUOY HAS BEEN SHOWING A STEADY DECLINE IN COMBINED SEAS
SINCE THE PEAK OF 16 FEET YESTERDAY MORNING. LATEST READING SHOWS
SEAS HAVE FALLEN TO 9 FEET. 9-BAND PLOT FROM THE BUOY INDICATES
ENERGY IS ABOUT EVENLY SPLIT BETWEEN LONG PERIOD SOUTHEAST SWELL
AND TRADE-WIND SWELL FROM THE SOUTHEAST. LATEST SCATTEROMETRY
INDICATES GALES ASSOCIATED WITH SUPER TYPHOON MAYSAK HAVE SHIFTED
WELL TO THE SOUTHWEST OF GUAM. PREVALENT WINDS OVER THE MARINE
ZONES ARE ABOUT 20 KNOTS...JUST BELOW THE SMALL CRAFT ADVISORY
THRESHOLD. BASED UPON ALL OF THIS PLAN ON DROPPING BOTH THE SMALL
CRAFT ADVISORY AND HIGH SURF ADVISORY AS SCHEDULED AT 6 AM THIS
MORNING.

&&

.FIRE WEATHER...
WETTING RAINFALLS DURING THE PAST COUPLE OF DAYS HAVE MITIGATED
THE SHORT TERM FIRE DANGER. ABOUT TWO THIRDS OF AN INCH OF
RAINFALL HAS FALLEN DURING THE PAST COUPLE OF DAYS AT WFO GUAM.
DRIER WEATHER WILL RESUME AROUND MID WEEK.

&&

.EASTERN MICRONESIA...
NOW THAT MAYSAK IS WELL WEST OF THE REGION...LOW INVEST AREA 99W
HAS BECOME THE MAIN FOCUS OF THE EASTERN MICRONESIA FORECAST. A
WEAK CIRCULATION IS EVIDENT SOUTHEAST OF KOSRAE ON THE LATEST
ASCAT ANALYSIS. CONVERGING WINDS TO THE NORTHEAST OF THE
CIRCULATION ARE GENERATING SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS ACROSS THE SOUTHERN MARSHALL ISLANDS...INCLUDING
MAJURO...AND OVER A LARGE PORTION OF KOSRAE STATE. THE GFS40 AND
NAVGEM REMAIN CONSISTENT IN DEVELOPING THIS SYSTEM AND MOVING IT
OUT TO THE NORTHWEST. REGARDLESS OF HOW THE SYSTEM DEVELOPS...AN
ACTIVE WEATHER PATTERN WILL CONTINUE ACROSS EASTERN MICRONESIA.
MAJURO IS LIKELY TO SEE A DECREASE IN SHOWERS THIS EVENING...
THOUGH UNSETTLED CONDITIONS ARE EXPECTED TO REMAIN OVER THE
MARSHALLS THROUGH THE WEEKEND. SCATTERED SHOWERS OVER KOSRAE WILL
CONTINUE THROUGH AT LEAST THURSDAY NIGHT. SCATTERED SHOWERS WILL
REMAIN TO THE SOUTH AND EAST OF POHNPEI THROUGH TONIGHT...WITH WET
CONDITIONS LIKELY THERE BY THURSDAY MORNING.

FRESH TO STRONG TRADE WINDS AND LARGE WAVES WILL CAUSE HAZARDOUS 
SURF CONDITIONS FOR KOSRAE AND MAJURO AS WELL AS HAZARDOUS MARINE
CONDITIONS FOR MAJURO DURING THE NEXT 2 OR 3 DAYS.

&&

.WESTERN MICRONESIA...
FOR CHUUK...FAIR CONDITIONS WILL CONTINUE FOR THE NEXT COUPLE OF
DAYS. INVEST AREA 99W...CURRENTLY SOUTHEAST OF KOSRAE...IS
EXPECTED TO STRENGTHEN OVER THE NEXT FEW DAYS AND MOVE TOWARD THE
NORTHWEST. EXACTLY HOW STRONG THE SYSTEM WILL BECOME IS STILL
QUESTIONABLE. THE GFS40 AND NAVGEM INDICATE SIGNIFICANT
DEVELOPMENT WHILE THE ECMWF AND UKMET SHOW ONLY A WEAK CIRCULATION
MOVING THROUGH CHUUK. EITHER WAY...SCATTERED SHOWERS ARE LIKELY
FRIDAY INTO THE WEEKEND. THE SYSTEM WILL NEED TO BE MONITORED TO
DETERMINE IF WINDS AND SEAS NEED TO BE INCREASED FOR THE WEEKEND.

FOR YAP AND KOROR...A TYPHOON WARNING REMAINS IN EFFECT FOR YAP
ISLAND. SUPER TYPHOON MAYSAK IS MOVING WEST-NORTHWESTWARD AND IS
NOW CENTERED JUST NORTHEAST OF YAP. MAYSAK WILL CONTINUE TO MOVE
WEST-NORTHWESTWARD AND PASS JUST NORTH OF YAP THIS MORNING...WITH
TYPHOON FORCE WINDS LIKELY THERE...ESPECIALLY OVER THE NORTHERN
COASTAL WATERS. TROPICAL STORM FORCE WINDS ARE LIKELY TO CONTINUE
ON YAP UNTIL AROUND NOON. KOROR WILL SEE INCREASING CLOUDINESS
WITH SCATTERED SHOWERS LATER THIS MORNING. WEATHER SHOULD
GRADUALLY IMPROVE AND SEAS SETTLE DOWN THURSDAY AND FRIDAY ACROSS
FAR WESTERN MICRONESIA.

SUPER TYPHOON MAYSAK PASSING BY JUST TO THE NORTH OF YAP THIS 
MORNING WILL MAINTAIN DANGEROUS SURF AND SEA CONDITIONS FOR PALAU 
THROUGH TODAY. THE CURRENT TYPHOON WARNING FOR YAP SUPERSEDES ANY 
SURF ADVISORY FOR YAP.

&&

.GUM WATCHES/WARNINGS/ADVISORIES...
GU...HIGH SURF ADVISORY UNTIL 6 AM CHST EARLY THIS MORNING FOR 
     GUZ001>004.

MARIANAS WATERS...SMALL CRAFT ADVISORY UNTIL 6 AM CHST EARLY THIS
                  MORNING FOR PMZ151>154.
