WTPS21 PGTW 20020525 01:30z
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
145 NM EITHER SIDE OF A LINE FROM 7.0S7 155.0E1 TO 9.4S3 151.7E4
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT
IMAGERY AT 250030Z0 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 7.5S2 154.0E0. THE SYSTEM IS MOVING WESTWARD AT 04
KNOTS. THE NEXT SATELLITE INVESTIGATION IS SCHEDULED FOR
260000Z8.
2. REMARKS:
MULTI-SPECTRAL ANIMATION AND A 37 GHZ TRMM PASS DEPICT A
DEVELOPING BANDING FEATURE WRAPPING IN TOWARD THE LOW-LEVEL
CIRCULATION CENTER (LLCC) FROM THE SOUTHEAST. MAXIMUM SUSTAINED
WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED AT 1000 MB. THE SYSTEM IS FORECAST TO REMAIN BENEATH
THE SUB-EQUATORIAL RIDGE. THEREFORE, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
260130Z2.//

REMARKS:
TROPICAL CYCLONE (TC) 25P, LOCATED IN THE SOLOMON SEA, HAS TRACKED
SOUTHWESTWARD AT 04 KNOTS DURING THE PAST 6 HOURS. THE WARNING
POSITION IS BASED ON 251130Z2 ENHANCED INFRARED SATELLITE IMAGERY
AND A 250950Z1 SPECIAL SENSOR MICROWAVE IMAGER (SSMI) PASS. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 35 AND 45 KNOTS. THE RECENT SSMI PASS DEPICTS DEEP CONVECTION
BEGINNING TO BUILD OVER THE LOW LEVEL CIRCULATION CENTER (LLCC) WITH
A BAND OF DEEP CONVECTION DEVELOPING IN THE SOUTHEAST QUADRANT.
ANIMATED SATELLITE IMAGERY INDICATES INCREASING DEEP CONVECTION OVER
THE LLCC OVER THE PAST 6 HOURS. TC 25P IS FORECAST TO TRACK SLOWLY
SOUTHWESTWARD THEN SOUTHWARD IN A VERY WEAK STEERING ENVIRONMENT
MAINLY DOMINATED BY A WEAK LOW TO MID LEVEL RIDGE TO THE EAST. THE
FORECAST IS BASED ON A BLEND OF THE AVAILABLE DYNAMIC AIDS,
INCLUDING NOGAPS AND THE NCEP AVIATION (AVN) MODELS. THE SYSTEM IS
FORECAST TO INTENSIFY AT A SLIGHTLY LESS THAN CLIMATOLOGICAL RATE AS
THE SYSTEM MOVES UNDER THE UPPER-LEVEL RIDGE AXIS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 251200Z0 IS 10 FEET. THIS WARNING

POSITION IS BASED ON 251730Z8 ENHANCED INFRARED SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY
ESTIMATES OF 35 KNOTS. SATELLITE ANIMATION DEPICTS THAT THE DEEP
BURSTS OVER THE LLCC HAVE SUSTAINED OVER THE PAST 6 HOURS. A BANDING
FEATURE REMAINS OVER THE SOUTHEAST QUADRANT. A LOW/MID (ROSSBY)
RIDGE SITUATED OVER THE SOLOMON ISLANDS SHOULD INFLUENCE THE

INDICATES A REVERSE TROUGH FORMATION CAUSING TC 25P AND A TROPICAL
DISTURBANCE EAST OF THE SOLOMON ISLANDS TO TURN TO THE SOUTHEAST.

POSITION IS BASED ON 252330Z5 VISIBLE SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35

POSITION IS BASED ON 261730Z9 INFRARED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES

COVERAGE HAS DECREASED SIGNIFICANTLY. WATER VAPOR AND THE 200 MB
ANAL INDICATE THAT THE SYSTEM HAS JUST SLIPPED POLEWARD OF THE RIDGE
AXIS. SO, WE EXPECT A WEAKENING TREND THROUGH THE PERIOD. A
RELATIVELY WEAK LOW/MID LEVEL RIDGE SITUATED OVER THE SOLOMON
ISLANDS SHOULD INFLUENCE THE TRACK THROUGH THE PERIOD. THEREFORE, TC
25P IS EXPECTED TO TRACK SLOWLY SOUTHWARD OVER THE NEXT 72 HOURS.
GFDN, AVN, AFWA MM5, THE BOM TCLAPS, AND THE UKMET GRID POINT, ALL
INDICATE A WEAKENING TREND AND A DRIFT TO THE SOUTH. NOGAPS,

REMARKS:
270300Z2 POSITION NEAR 9.1S0 153.9E8.
TROPICAL CYCLONE (TC) 25P (UPIA), LOCATED OVER THE SOLOMON SEA, HAS
REMAINED QUASI-STATIONARY DURING THE PAST 6 HOURS. LITTLE, IF ANY,
MOTION HAS BEEN OBSERVED FOR OVER 9 HOURS. THE WARNING POSITION IS
BASED ON 262330Z6 MULTI-SPECTRAL SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 35 KNOTS. THE 262030Z3 MULTI-SPECTRAL IMAGE DEPICTED A FULLY
EXPOSED LOW-LEVEL CIRCULATION CENTER ABOUT 40 NM NORTH OF THE
PREVIOUS WARNING POSITION. HOWEVER, RECENT IMAGERY REVEALS THAT THE
CONVECTION HAS BEGUN TO BUILD BACK OVER THE CENTER. A RELATIVELY
WEAK LOW/MID LEVEL RIDGE SITUATED OVER THE SOLOMON ISLANDS SHOULD
INFLUENCE THE TRACK THROUGH THE PERIOD. THEREFORE, TC 25P IS
EXPECTED TO DRIFT SLOWLY SOUTHWARD OVER THE NEXT 72 HOURS. AVN, AFWA
MM5, THE BOM TCLAPS, AND THE UKMET GRID POINT, ALL INDICATE A
WEAKENING TREND AND A DRIFT TO THE SOUTH. NOGAPS, AND THE NEW GFDN
18Z9 RUN, HOWEVER, KEEP THE SYSTEM COUPLED IN THE MID-LEVEL AND
TRACK THE SYSTEM DEEPER AND FASTER INTO THE SUBTROPICS. OUR FORECAST
IS BASED ON A WEAKENING/DISSIPATION TREND. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 270000Z9 IS 12 FEET. NEXT WARNINGS AT 270900Z8, 271500Z5,
272100Z2 AND 280300Z3.//

REMARKS:
270900Z8 POSITION NEAR 8.8S6 153.9E8.
TROPICAL CYCLONE (TC) 25P (UPIA), LOCATED OVER THE SOLOMON SEA, HAS
DRIFTED NORTH AT 02 KNOTS DURING THE PAST 6 HOURS. THE WARNING
POSITION IS BASED ON 270530Z7 MULTI-SPECTRAL SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 35 KNOTS. MULTI-SPECTRAL IMAGERY DEPICTED A FULLY EXPOSED LOW-
LEVEL CIRCULATION CENTER (LLCC) WITH THE NEAREST CONVECTION
APPROXIMATELY 65 NM TO THE SOUTH. A RELATIVELY WEAK LOW TO MID LEVEL
RIDGE SITUATED EAST OF THE SOLOMON ISLANDS SHOULD INFLUENCE THE
TRACK THROUGH THE PERIOD. TC 25P IS EXPECTED TO DRIFT SLOWLY SOUTH-
SOUTHEASTWARD OVER THE NEXT 72 HOURS. NOGAPS, AVN, AFWA MM5, THE BOM
TCLAPS, AND THE UKMET GRID POINT MODELS, ALL INDICATE A WEAKENING
TREND AND A DRIFT TO THE SOUTH. GFDN, HOWEVER, KEEPS THE SYSTEM
COUPLED IN THE MID-LEVEL AND TRACKS THE SYSTEM FASTER INTO THE
SUBTROPICS. OUR FORECAST IS BASED ON THE MODELS THAT DEPICT A
WEAKENING/DISSIPATION TREND. MAXIMUM SIGNIFICANT WAVE HEIGHT AT

TROPICAL CYCLONE (TC) 25P (UPIA), LOCATED OVER THE SOLOMON SEA, HAS

REMARKS:
280300Z3 POSITION NEAR 9.3S2 154.0E0.
TROPICAL CYCLONE (TC) 25P (UPIA), LOCATED OVER THE SOLOMON SEA, HAS
TRACKED SOUTH-SOUTHEAST AT 05 KNOTS DURING THE PAST 6 HOURS. THE
WARNING POSITION IS BASED ON 272330Z7 VISIBLE SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 35 KNOTS. ANIMATED VISIBLE SATELLITE IMAGERY DEPICTS THE LOW
LEVEL CIRCULATION CENTER (LLCC) NORTH OF NEW DEEP CONVECTION WHICH
HAS BEEN RE-DEVELOPING OVER THE LAST FEW HOURS. A LOW TO MID LEVEL
RIDGE SITUATED EAST OF THE SOLOMON ISLANDS WILL INFLUENCE THE
SYSTEM'S TRACK THROUGH THE PERIOD. TC 25P IS EXPECTED TO TRACK
SOUTH-SOUTHEASTWARD AND WEAKEN OVER THE NEXT 48 HOURS. ALL MODELS
WITH THE EXCEPTION OF AVN INDICATE A SLOW WEAKENING TREND AND A
TRACK TO THE SOUTH AND SOUTHEAST, TRACKING THE SYSTEM INTO THE
SUBTROPICS. AVN RAPIDLY WEAKENS THE SYSTEM WHILE REMAINING QUASI-
STATIONARY. THEREFORE, OUR FORECAST IS BASED ON A BLEND OF ALL
MODELS WITH THE EXCEPTION OF AVN. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
280000Z0 IS 12 FEET. NEXT WARNINGS AT 280900Z9, 281500Z6, 282100Z3

REMARKS:
280900Z9 POSITION NEAR 10.0S1 154.4E4.
TROPICAL CYCLONE (TC) 25P (UPIA), LOCATED OVER THE SOLOMON SEA, HAS
TRACKED SOUTH-SOUTHEASTWARD AT 04 KNOTS DURING THE PAST 6 HOURS. THE
WARNING POSITION IS BASED ON 280530Z8 MULTI-SPECTRAL SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 30 KNOTS AND A RECENT QUIKSCAT PASS
INDICATING WINDS OF 30 KNOTS NEAR THE CENTER. ANIMATED SATELLITE
IMAGERY SHOWS THAT THE LOW LEVEL CIRCULATION CENTER (LLCC) IS
DISPLACED NORTH OF THE CYCLING DEEP CONVECTION. TC 25P IS EXPECTED
TO REMAIN BELOW TROPICAL STORM STRENGTH AS IT CONTINUES TO TRACK
SOUTHEASTWARD IN AN UNFAVORABLE ENVIRONMENT. ALL MODELS AGREE WITH
THIS SCENARIO. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 280600Z6 IS 12
FEET. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON
WARNING CENTER (NAVPACMETOCCEN). THE SYSTEM WILL BE CLOSELY
MONITORED FOR SIGNS OF REGENERATION.//
