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:
      (1) AT 04APR26 0000Z, TROPICAL CYCLONE 30P (THIRTY) WAS LOCATED 
NEAR 9.1S 155.1E, APPROXIMATELY 717 NM NORTHEAST OF CAIRNS, AUSTRALIA, 
AND HAD TRACKED NORTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 
45 KNOTS. SEE REF A (WTPS31 PGTW 040300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90P) PREVIOUSLY LOCATED NEAR 
9.0S 173.0E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE 
PARA. 2.A.(1) FOR FURTHER DETAILS.
      (2) THE AREA OF CONVECTION (INVEST 91P) HAS PERSISTED NEAR 9.0S 
173.0E, APPROXIMATELY 590 NM NORTH-NORTHEAST OF PORT VILA. ANIMATED 
ENHANCED MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 030047Z OCEANSAT 
DEPICTS AN AREA OF CALMER WINDS (5-10 KTS) CLOSER TO THE CENTER, WHILE 
MORE ELEVATED WINDS (10-15 KTS) ARE OBSERVED ALONG THE NORTHERN FLANK 
OF THE CIRCULATION. WITHIN THE STRUCTURE OF 91P, MULTIPLE 
MESOVORTICIES ROTATING CYCLONICALLY ARE IDENTIFIABLE. UPPER AIR 
ANALYSIS INDICATES A MARGINALLY FAVORABLE ENVIRONMENT FOR FURTHER 
DEVELOPMENT WITH LOW (10-15 KTS) VERTICAL WIND SHEAR, WARM (29-30 C) 
SEA SURFACE TEMPERATURES AND A MODERATE POLEWARD OUTFLOW CHANNEL 
ASSISTING THE SYSTEM. MODEL GUIDANCE IS IN GOOD AGREEMENT ON A 
SOUTHWESTWARD TRACK WITH STEADY INTENSIFICATION OVER THE NEXT 24-48 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS REMAINS LOW.
      (3) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO WARNING 
STATUS.//
