REMARKS:
030900Z POSITION NEAR 23.2S 179.1W.
TROPICAL CYCLONE 18P (JOSIE), LOCATED APPROXIMATELY 304 NM SOUTH-
SOUTHEAST OF SUVA, FIJI, HAS TRACKED SOUTHEASTWARD AT 16 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MSI SHOWS A RAGGED AND FULLY EXPOSED LLC
WITH FLARING CONVECTION SHEARED TO THE EASTERN FLANK. THE INITIAL
POSITION IS BASED WITH HIGH CONFIDENCE ON THE LLC IN THE MSI LOOP AND
MATCHES THE LOW REFLECTIVITY CIRCULATION FEATURE IN THE 030552Z
SSMIS MICROWAVE PASS. THE INITIAL INTENSITY IS HEDGED HIGHER THAN
DVORAK INTENSITY ESTIMATES RANGING FROM 25-30 KNOTS TO ACCOUNT FOR
THE SUSTAINED LLC STRUCTURE. TC 18P HAS ACCELERATED INTO AN AREA OF
HIGH (GREATER THAN 30-KNOT) VWS. CONCURRENTLY, THE CYCLONE IS RAPIDLY
BECOMING SUBTROPICAL AS EVIDENCED BY ITS EXPANDING WIND FIELD AND
ASYMMETRIC PROFILE. THE CYCLONE IS EXPECTED TO CONTINUE ALONG ITS
TRACK AND DEEPER INTO HIGHER VWS AREA. IN VIEW OF THIS, TC JOSIE IS
EXPECTED TO DISSIPATE AND BECOME SUBTROPICAL BY TAU 12 OR SOONER.
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. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 030600Z IS 12 FEET.
REFER TO TROPICAL CYCLONE 17P (IRIS) WARNINGS (WTPS32 PGTW) FOR
