AMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR 
15.6N 112.5E IS NOW LOCATED NEAR 18.0N 110.3E, APPROXIMATELY 122 NM 
SOUTH OF HAIKOU, HAINAN. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 
062052Z SSMI 85GHZ MICROWAVE IMAGE DEPICT A BROAD LOW LEVEL CIRCULATION 
(LLC) WITH FLARING CONVECTION DISPLACED TO THE WEST OF THE LLC. UPPER-
LEVEL ANALYSIS REVEALS A MARGINAL ENVIRONMENT FOR DEVELOPMENT WITH 
MODERATE TO HIGH VERTICAL WIND SHEAR (VWS), WESTWARD 
OUTFLOW, AND WARM SEA SURFACE TEMPERATURES (30-31C). GLOBAL DYNAMIC 
MODELS ARE IN GOOD AGREEMENT THAT 97W WILL CONTINUE TO TRACK ALONG THE 
PERIPHERY OF A SUBTROPICAL RIDGE SITUATED TO THE NORTH AND NORTHEAST AS 
IT CONSOLIDATES AND TRACKS GENERALLY WESTWARD. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH.
      (2) NO OTHER SUSPECT AREAS.
   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: NONE.
3. JUSTIFICATION FOR REISSUE: REISSUED TCFA IN  PARA 1.B.(1) //
