1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   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:
      (1) THE AREA OF CONVECTION (INVEST 90P) PREVIOUSLY LOCATED NEAR 
14.9S 154.8E IS NOW LOCATED NEAR 15.2S 154.2E, APPROXIMATELY 253 NM 
NORTHEAST OF WILLIS ISLAND. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
(MSI) AND A 210331Z AMSR2 89GHZ IMAGE DEPICT A CONSOLIDATING LOW LEVEL 
CIRCULATION CENTER (LLCC) WITH FRAGMENTED, FORMATIVE BANDING ON THE 
OUTSKIRTS OF THE LLCC. UPPER-LEVEL ANALYSIS REVEALS A MARGINALLY 
FAVORABLE ENVIRONMENT, WITH GOOD OUTFLOW ALOFT, WARM SSTS (29-30 C), 
OFFSET BY HIGH VWS (20-30 KT). GLOBAL MODELS ARE IN GOOD AGREEMENT 
THAT 90P WILL CONTINUE TRACKING SOUTHWESTWARD AND FURTHER DEVELOP OVER THE 
NEXT 24-36 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 
TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 999 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS REMAINS HIGH. SEE REF A (WTPS21 PGTW 210530) 
FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
