1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR 
18.3N 107.3E IS NOW LOCATED NEAR 18.3N 108.1E, APPROXIMATELY 136 NM NORTH 
OF DA NANG. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS AN 
OBSCURED AND ELONGATED AREA OF SHARP TROUGHING WHERE A POORLY-DEFINED 
LOW-LEVEL CIRCULATION (LLC) WITH DISORGANIZED FLARING CONVECTION ALONG A 
STATIONARY BOUNDARY USED TO EXIST. ENVIRONMENTAL ANALYSIS REVEALS AN 
UNFAVORABLE ENVIRONMENT FOR FURTHER DEVELOPMENT WITH WEAK EQUATORWARD 
OUTFLOW AND WARM SEA SURFACE TEMPERATURES (28-29 C). HOWEVER, AS THE 
SYSTEM TRANSITS SOUTH OUT OF THE BAY OF TONKIN IT WILL BE MET BY HIGH 
VERTICAL WIND SHEAR OF 25-30 KNOTS. GLOBAL MODELS ARE IN GOOD AGREEMENT 
THAT INVEST 93W WILL CONTINUE TO WEAKEN AS IT TRACKS EAST-SOUTHEASTERLY 
AROUND THE COAST OF HAINAN OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE 
IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO 
LOW.
      (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: DOWNGRADED AREA IN PARA 1.B.(1) TO LOW.//
