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 91P) PREVIOUSLY LOCATED NEAR 
18.5S 164.3E IS NOW LOCATED NEAR 18.9S 164.1E, APPROXIMATELY 236 NM WEST-
SOUTHWEST OF PORT VILLA, VANUATU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
(MSI) DEPICTS A FULLY-EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) EMBEDDED 
IN THE MONSOON TROUGH EXTENDING THROUGH THE SOUTH PACIFIC WITH FLARING 
CONVECTION TO THE SOUTHEAST OF THE SYSTEM ASSOCIATED WITH THE SOUTH 
PACIFIC CONVERGENCE ZONE (SPCZ). ENVIRONMENTAL ANALYSIS REVEALS MARGINAL 
CONDITIONS MOVING FORWARD WITH A GOOD EQUATORWARD OUTFLOW CHANNEL ALOFT 
AND VERY WARM SEA SURFACE TEMPERATURES OF 30-32 C, OFFSET BY MODERATE TO 
HIGH VERTICAL WIND SHEAR OF 30-35 KNOTS. GLOBAL DETERMINISTIC MODELS 
INDICATE WEAK DEVELOPMENT OVER THE NEXT 24 HOURS, WITH A SOUTHWARD TRACK 
AND A SMALL WINDOW OF POTENTIAL TC INTENSITY. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1001 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
