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) AN AREA OF CONVECTION (INVEST 90P) HAS PERSISTED NEAR 15.2S 
152.4E, APPROXIMATELY 459 NM EAST OF CAIRNS, AUSTRALIA. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A BROAD LOW LEVEL 
CIRCULATION (LLC) WITH FLARING CONVECTION IN THE NORTHERN PERIPHERY OF 
THE SYSTEM THAT SLIGHTLY OBSCURES THE LOW LEVEL CIRCULATION CENTER 
(LLCC). THE ENVIRONMENT IS FAVORABLE FOR DEVELOPMENT WITH LOW (5-10 KTS) 
VERTICAL WIND SHEAR, WARM (29-30 C) SEA SURFACE TEMPERATURE VALUES, AND 
GOOD EQUATORWARD OUTFLOW ALOFT.  THE PRIMARY HINDRANCE FOR INVEST 90P IS 
THE SIGNIFICANT MID-LEVEL SHEAR FROM THE UPPER LEVEL TROUGH TO THE 
SOUTHEAST WHICH IS PREVENTING CONVECTION FROM WRAPPING INTO THE SYSTEM 
AND KEEPING THE VORTEX CONFINED TO THE LOWER LEVELS. THE SLOW 
ORGANIZATION OF CIRCULATION IS ALSO EVIDENT ON RECENT TOTAL PRECIPITABLE 
WATER ANIMATION. GLOBAL MODELS ARE IN AGREEMENT THAT INVEST 90P WILL 
CONTINUE ON AN EASTWARD TRACK WITH STEADY INTENSIFICATION OVER THE NEXT 
24 HOURS WHILE MOVING INTO AN EVEN MORE FAVORABLE ENVIRONMENT AS THE 
TROUGH CONTINUES ON AND MID-LEVEL SHEAR FROM THE SOUTH DECREASES.  
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 17 TO 22 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 
LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED LOW AREA IN PARA. 2.B.(1) .//
