1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 10APR22 0000Z, TROPICAL STORM 02W (MALAKAS) WAS LOCATED 
NEAR 11.6N 140.3E, APPROXIMATELY 109 NM NORTH OF FAIS, AND HAD 
TRACKED NORTHWESTWARD AT 25 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS GUSTING TO 70 
KNOTS. SEE REF A (WTPN31 PGTW 100300) FOR FURTHER DETAILS.
      (2) AT 10APR22 0000Z, TROPICAL STORM 03W (MEGI) WAS LOCATED 
NEAR 11.3N 126.0E, APPROXIMATELY 353 NM SOUTHEAST OF MANILA, 
PHILIPPINES, AND HAD TRACKED NORTHWESTWARD AT 04 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 
KNOTS GUSTING TO 50 KNOTS. SEE REF B (WTPN32 PGTW 100300) FOR 
FURTHER DETAILS.
      (3) 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 23P) PREVIOUSLY LOCATED 
NEAR 25.9S 167.6E IS NOW LOCATED NEAR 25.0S 168.6E, APPROXIMATELY 
200 NM SOUTHEAST OF NOUMEA, NEW CALEDONIA. THE SYSTEM IS CURRENTLY 
CLASSIFIED AS A SUBTROPICAL STORM, GENERALLY CHARACTERIZED AS HAVING 
BOTH TROPICAL AND MID-LATITUDE CYCLONE FEATURES. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY (MSI) AND 100202Z AMSR2 36GHZ 
MICROWAVE IMAGE DEPICT A LOW-LEVEL CENTER THAT IS FULLY EXPOSED, 
LITTLE CONVECTIVE ACTIVITY, WITH THE SUBTROPICAL JET TO THE SOUTH. A 
RECENT ASCAT IMAGE SHOWS MAXIMUM SURFACE WINDS AT 35 KNOTS TO THE 
SOUTHEAST. ENVIRONMENTAL ANALYSIS DEPICTS AN UNFAVORABLE ENVIRONMENT 
FOR REDEVELOPMENT OF A TROPICAL CYCLONE CHARACTERIZED BY STRONG 
(25KTS+) VERTICAL WIND SHEAR (VWS) COOL (25-26C) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS AGREE THAT 23P WILL TRANSITION TO AN 
EXTRATROPICAL SYSTEM AS A MAJOR SHORT WAVE TROUGH APPROACHES FROM 
THE SOUTHWEST IN 24-36 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 33 TO 38 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 986 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.//
