1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 09SEP21 0600Z, SUPER TYPHOON 19W (CHANTHU) WAS LOCATED 
NEAR 15.7N 127.2E, APPROXIMATELY 365 NM EAST OF MANILA, PHILIPPINES, 
AND HAD TRACKED WEST-NORTHWESTWARD AT 09 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 130 KNOTS 
GUSTING TO 160 KNOTS. SEE REF A (WTPN32 PGTW 090900) FOR FURTHER 
DETAILS.
      (2) AT 09SEP21 0600Z, TROPICAL STORM 18W (CONSON) WAS LOCATED 
NEAR 16.0N 117.1E, APPROXIMATELY 241 NM WEST-NORTHWEST OF MANILA, 
PHILIPPINES, AND HAD TRACKED WEST- NORTHWESTWARD AT 14 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED 
AT 50 KNOTS GUSTING TO 65 KNOTS. SEE REF B (WTPN31 PGTW 090900) FOR 
FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 96W) HAS PERSISTED NEAR 
17.0N 132.7E, APPROXIMATELY 623 NM SOUTH-SOUTHEAST OF KADENA AB. 
ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS FLARING 
CONVECTION OVER AN ILL-DEFINED LOW LEVEL CIRCULATION (LLC). A 
090913Z SSMIS 91GHZ SATELLITE IMAGE REVEALS A POCKET OF DEEP 
CONVECTION DISPLACED TO THE SOUTH OF THE LLC, AND AN OVERALL LACK OF 
CONVECTIVE ORGANIZATION. INVEST 96W IS IN A MARGINAL ENVIRONMENT 
CHARACTERIZED BY WARM (30C) SEA SURFACE TEMPERATURES (SST) OFFSET BY 
MODERATE (15-25 KT) VERTICAL WIND SHEAR (VWS), AND WEAK OUTFLOW 
ALOFT. GLOBAL MODELS GENERALLY AGREE THAT 96W WILL DISSIPATE AS IT 
INTERACTS WITH STY 19W, WITH THE EXCEPTION OF GFS WHICH DEPICTS 96W 
TRACKING POLEWARD OF STY 19W AND CONSOLIDATING. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 1010 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.
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: ADDED AREA IN PARA 1.B.(1) AS LOW.//
