1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90P) PREVIOUSLY LOCATED NEAR 
14.9S 169.5E IS NOW LOCATED NEAR 15.5S 171.1E, APPROXIMATELY 214 NM 
NORTHEAST OF PORT VILA, VANUATU. ANIMATED MULTISPECTRAL VISUAL IMAGERY 
(MSI) DEPICT INVEST 90P CONTINUING TO CONSOLIDATE AROUND A LOW-LEVEL 
CIRCULATION CENTER (LLCC) WITH DEEP FLARING CONVECTION BUILDING IN THE 
VICINITY OF THE LLCC. THE 272128Z ASCAT PASS SHOWS A NEARLY SYMMETRICAL 
LOW LEVEL WIND FIELD WITH HIGHER WINDS (25-30KTS) ALONG THE NORTHEASTERN 
BOUNDARY OF THE CIRCULATION. STRUCTURALLY THE SYSTEM REMAINS TILTED WITH 
DEEP CONVECTION DISPLACED TO THE SOUTHEAST DELAYING A TIGHTER RADIUS AND 
STRONGER WIND SPEEDS. GLOBAL DETERMINISTIC MODEL GUIDANCE IS IN 
AGREEMENT ON A SOUTH-SOUTHEASTWARD TRACK, WHILE BECOMING MORE VERTICALLY 
ALIGNED AND INTENSIFYING, OVER THE NEXT 12 HOURS. THE LLCC WILL BE 
MIGRATING TOWARD AN AREA OF HIGH VERTICAL WIND SHEAR (30-40KT) AND 
RELATIVELY DRIER AIR GIVING THIS SYSTEM AN EXTREMELY SHORT WINDOW OF 
INTENSIFICATION AND LIFESPAN MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO 
BE NEAR 993 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH. SEE REF A 
(WTPS21 PGTW 280230) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
