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 20MAR26 0000Z, TROPICAL CYCLONE 27P (NARELLE) WAS LOCATED 
NEAR 13.4S 143.0E, APPROXIMATELY 265 NM NORTHWEST OF CAIRNS, AUSTRALIA, 
AND HAD TRACKED WESTWARD AT 10 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 105 KNOTS GUSTING TO 130 
KNOTS. SEE REF A (WTPS31 PGTW 200300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF DISORGANIZED CONVECTION (INVEST 98P) HAS PERSISTED 
NEAR 10.7S 164.0E, APPROXIMATELY 245 NM EAST-SOUTHEAST OF HONIARA, 
SOLOMON ISLANDS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS 
A VERY BROAD CIRCULATION WITH A POORLY ORGANIZED LLCC AND ISOLATED 
POCKETS OF SHORT-LIVED FLARING CONVECTION. ENVIRONMENTAL FACTORS FOR THE 
AREA OF CONVECTION (98P) ARE MARGINALLY FAVORABLE WITH LOW TO MODERATE 
(15-20KTS) OF VERTICAL WIND SHEAR, WARM (28-29C) SEA SURFACE 
TEMPERATURES, AND GOOD EQUATORWARD OUTFLOW ALOFT. GLOBAL DETERMINISTIC 
MODELS ARE IN AGREEMENT THAT 98P WILL CONTINUE TO TRACK SOUTHEASTERLY 
AND QUICKLY CONSOLIDATE OVER THE NEXT 36-48 HOURS AS THE SYSTEM TRANSITS 
SOUTH OF THE SOLOMON ISLANDS.  MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO 
BE NEAR 1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
