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: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 99P) PREVIOUSLY LOCATED NEAR 
15.6S 165.1E IS NOW LOCATED NEAR 18.1S 165.0E, APPROXIMATELY 260 NM 
NORTH-NORTHWEST OF NOUMEA, NEW CALEDONIA. THE SYSTEM IS CURRENTLY 
CLASSIFIED AS A SUBTROPICAL DEPRESSION, GENERALLY CHARACTERIZED AS HAVING 
BOTH TROPICAL AND MID-LATITUDE CYCLONE FEATURES. ANIMATED MULTISPECTRAL 
SATELLITE IMAGERY (MSI) AND A 151910Z SSMIS 91GHZ MICROWAVE IMAGE DEPICT 
AN ELONGATED PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH 
FRAGMENTED CONVECTIVE BANDING ALONG THE EASTERN PERIPHERY. 99P IS IN AN 
UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH AN UPPER LEVEL TROUGH THAT 
HAS JET FINGER SUPPORT IMPARTING UPWARDS OF 50 KNOTS OF SHEAR ON THE 
WESTERN EDGE, YET THE CENTER IT IS STILL WITHIN WARM (29-30C) WARM WATERS 
AND A SMALL BUBBLE OF LOW TO MODERATE (10-15KTS) VWS. GLOBAL MODELS ARE 
IN AGREEMENT THAT 99P WILL CONTINUE ON A SOUTH-SOUTHEASTWARD TRACK 
CROSSING NEW CALEDONIA WITH NO FURTHER INDICATIONS OF FURTHER 
DEVELOPMENT. ONCE CROSSING THE ISLAND, IT IS EXPECTED TO BECOME ABSORBED 
WITHIN THE LONGWAVE PATTERN WHERE IT WILL MAKE ITS TRANSITION INTO A 
PROPER SUBTROPICAL LOW WITHIN THE UPCOMING DAYS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 23 TO 27 KNOTS. MINIMUM SEA LEVEL PRESSURE 
IS ESTIMATED TO BE NEAR 1001 MB. FOR HAZARDS AND WARNINGS, REFERENCE THE 
FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO 
LOCAL WMO DESIGNATED FORECAST AUTHORITY. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
3. JUSTIFICATION FOR REISSUE: ADDED AREA IN 2.C. (1) AS A LOW.////
