1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 03JUN23 0000Z, TROPICAL STORM 02W (MAWAR) WAS LOCATED NEAR 
30.7N 138.1E, APPROXIMATELY 287 NM SOUTH-SOUTHWEST OF YOKOSUKA, JAPAN, 
AND HAD TRACKED EAST-NORTHEASTWARD AT 28 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 
KNOTS. SEE REF A (WTPN31 PGTW 030300) FOR THE FINAL WARNING ON THIS 
SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED NEAR 
10.3N 140.5E IS NOW LOCATED NEAR 10.0N 137.7E, APPROXIMATELY 36 NM 
NORTHWEST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 030403Z 
ATMS 88.2 GHZ PASS DEPICT A WEAK BROAD LOW-LEVEL CIRCULATION (LLC) 
ASSOCIATED WITH WEAK DISORGANIZED CONVECTION SURROUNDING THE LLC. A 
030011Z PARTIAL ASCAT-C PASS FURTHER REVEALS A WEAK CIRCULATION JUST 
NORTHWEST OF YAP. 98W IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT, 
CHARACTERIZED BY MODERATE OUTFLOW ALOFT AND LOW (10-15KT) VERTICAL WIND 
SHEAR. SEA SURFACE TEMPERATURES ARE ALSO CONDUCIVE AT A WARM 30C. 
DETERMINISTIC AND ENSEMBLE MODELS ARE IN FAIR AGREEMENT THAT INVEST 98W 
WILL BE SLOW TO DEVELOP AS IT TRACKS GENERALLY POLEWARD OVER THE NEXT 48 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 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 SUSPECT AREAS.
   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: NONE.//
