1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 09APR22 0000Z, TROPICAL STORM 02W (MALAKAS) WAS LOCATED 
NEAR 7.0N 144.5E, APPROXIMATELY 19 NM SOUTH-SOUTHEAST OF IFALIK, AND 
HAD TRACKED NORTHWARD AT 05 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS GUSTING TO 50 
KNOTS. SEE REF A (WTPN31 PGTW 090300) FOR FURTHER DETAILS.
      (2) AT 09APR22 0000Z, TROPICAL DEPRESSION 03W (THREE) WAS 
LOCATED NEAR 10.7N 126.8E, APPROXIMATELY 230 NM SOUTHEAST OF 
LEGAZPI, PHILIPPINES, AND HAD TRACKED SOUTH- SOUTHWESTWARD AT 03 
KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE 
ESTIMATED AT 25 KNOTS GUSTING TO 35 KNOTS. SEE REF B (WTPN32 PGTW 
090300) 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 25.3S 169.2E, APPROXIMATELY 
231 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 090301Z AMSR2 36GHZ 
MICROWAVE IMAGE DEPICT A LOW-LEVEL CENTER THAT IS FULLY EXPOSED, 
WITH SHEARED CONVECTION TO THE SOUTHEAST. 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) WITH 23P SLOWLY EMBEDDING ITSELF IN THE UPPER LEVEL 
WESTERLIES AND COOL (25-26C) SEA SURFACE TEMPERATURES. WITH 23P 
EMBEDDING ITSELF IN THE MID-LATITUDE JET, GLOBAL MODELS AGREE THAT 
23P WILL TRANSITION TO AN EXTRATROPICAL SYSTEM AS A MAJOR SHORT WAVE 
TROUGH APPROACHES FROM THE SOUTHWEST IN 52-70 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 33 TO 38 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 LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.//
