1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: 
     (1) AT 24APR21 1800Z, SUBTROPICAL STORM 02W (SURIGAE) WAS 
LOCATED NEAR 21.7N 134.1E, APPROXIMATELY 438 NM WEST-SOUTHWEST OF 
IWO TO, JAPAN, AND HAD TRACKED EAST-SOUTHEASTWARD AT 12 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED 
AT 40 KNOTS GUSTING TO 50 KNOTS. SEE REF A (WTPN31 PGTW 242100) FOR 
THE FINAL WARNING ON THIS SYSTEM.
     (2) NO OTHER TROPICAL CYCLONES.
   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: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
     (1) THE AREA OF CONVECTION (INVEST 96P) PREVIOUSLY LOCATED NEAR 
28.4S 142.2W IS NOW LOCATED NEAR 28.7S 142.4W, APPROXIMATELY 768 NM 
SOUTHEAST OF PAPEETE, FRENCH POLYNESIA. THE SYSTEM IS CURRENTLY 
CLASSIFIED AS A SUBTROPICAL STORM, GENERALLY CHARACTERIZED AS HAVING 
BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY AND ANIMATED WATER VAPOR LOOP INDICATES 
THE SYSTEM IS LOCATED DIRECTLY UNDER A BROAD UPPERLEVEL COLD CORE 
LOW. A 240234Z SSMIS 91GHZ IMAGE REVEALS FORMATIVE, SPIRAL BANDING 
WRAPPING INTO A LOW LEVEL CIRCULATION (LLC) WITH DEEP CONVECTION IN 
THE NORTHWEST AND SOUTHEAST PERIPHERIES. ENVIRONMENTAL ANALYSIS FOR 
INVEST 96P INDICATES A HOSTILE ENVIRONMENT, NOT CONDUCIVE FOR 
TROPICAL DEVELOPMENT DUE TO CONVERGENCE ALOFT AND COOL (25-26 
CELSIUS) SEA SURFACE TEMPERATURES. GLOBAL MODELS SHOW A GENERAL 
SOUTHWARD TRACK WITH MINIMAL INTENSIFICATION OVER THE NEXT 24-36 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30 TO 35 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
