REMARKS:
090900Z POSITION NEAR 27.1S 179.0E.
09APR26. TROPICAL CYCLONE 31P (VAIANU), LOCATED APPROXIMATELY 523
NM SOUTH OF SUVA, FIJI, HAS TRACKED SOUTH-SOUTHEASTWARD AT 06
KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED IMAGERY DEPICTS A
PARTIALLY EXPOSED LLCC WITH A BURST OF CONVECTION OVER THE SOUTHERN
SEMICIRCLE. THE SYSTEM EXHIBITS A HYBRID STRUCTURE CONSISTING OF
SWIRLING MID-LEVEL CLOUDS AND LITTLE CENTRAL CONVECTION, LOCATED IN AN
UNFAVORABLE ENVIRONMENT CHARACTERIZED BY 30 KTS OF VWS AND 25 DEGREE
CELSIUS SST. ENVIRONMENTAL ANALYSIS REVEALS WEAK TEMPERATURE ADVECTION
AND AN UPPER LEVEL TROUGH DIRECTLY ALOFT. THE POSITION AND INTENSITY
ARE ASSESSED WITH HIGH CONFIDENCE BASED ON THE EXPOSED CENTER AND A
082330Z OSCAT-3 IMAGE DEPICTING 50 KT WINDS, RESPECTIVELY. THE SYSTEM
WILL BE STEERED TOWARDS THE SOUTH BY A DEEP LAYER RIDGE TO THE EAST.
TC 31P WILL TURN TOWARDS THE SOUTHWEST AS A RIDGE APPROACHES NEW
ZEALAND FROM THE WEST AND INDUCES A MORE WESTWARD MOTION. WEAK
BAROCLINIC FORCING WILL CAUSE THE SYSTEM TO COMPLETE SUBTROPICAL
TRANSITION BY TAU 12 AND HELP TO SUSTAIN ITS INTENSITY THROUGH TAU 24,
FOLLOWED BY GRADUAL WEAKENING. THE FORECAST TRACK AND INTENSITY ARE
SET WITH HIGH CONFIDENCE BASED ON THE MULTI-MODEL CONSENSUS. THIS IS
THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL
HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF
REGENERATION. MINIMUM CENTRAL PRESSURE AT 090600Z IS 981 MB. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 090600Z IS 27 FEET. REFER TO TROPICAL
CYCLONE 30P (MAILA) WARNINGS (WTPS31 PGTW) FOR SIX-HOURLY UPDATES.//
