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 99P) PREVIOUSLY LOCATED 
NEAR 16.9S 148.5E IS NOW LOCATED NEAR 17.1S 148.2E, APPROXIMATELY 
140 NM EAST OF CAIRNS, AUSTRALIA. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY, A COMPOSITE RADAR LOOP FROM WILLIS ISLAND, AND A 280702Z 
SSMIS 91 GHZ MICROWAVE PASS REVEAL DISORGANIZED BANDING WRAPPING 
INTO A LOW LEVEL CIRCULATION CENTER (LLCC) WITH FLARING CONVECTION 
IN THE SOUTHERN PERIPHERY. A 281011Z ASCAT-A IMAGE DEPICTS A WELL 
DEFINED LLCC WITH 30-35KT WINDS IN THE SOUTHWEST QUADRANT. 
ENVIRONMENTAL ANALYSIS DEPICTS A FAVORABLE ENVIRONMENT WITH ROBUST 
POLEWARD UPPER LEVEL OUTFLOW, LOW TO MODERATE (15-20KTS) VERTICAL 
WIND SHEAR, AND WARM (29-30C) SEA SURFACE TEMPERATURES. GLOBAL 
MODELS INDICATE QUASI-STATIONARY MOVEMENT OFF THE COAST OF AUSTRALIA 
OVER THE NEXT 24 HOURS WITH STEADY INTENSIFICATION. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS IS UPGRADED TO HIGH.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 2.B.(1). TO
