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 
202 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 A 100206Z AMSR2 89HZ 
MICROWAVE IMAGE DEPICT A LOW-LEVEL CENTER THAT IS FULLY EXPOSED, 
WITH SHEARED CONVECTION 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 24-48 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.//
