1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED NEAR 
11.1N 130.9E IS NOW LOCATED NEAR 13.8N 133.8E, APPROXIMATELY 585 NM EAST 
OF LEGAZPI, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 
201336Z GMI 89 GHZ IMAGE DEPICT FLARING CONVECTION OFFSET TO THE EASTERN 
SEMICIRCLE PARTIALLY OBSCURING A BROAD ELONGATED LLC. THE RADIUS OF 
MAXIMUM WINDS (RMW) IS WELL OVER 160 NM. ENVIRONMENTAL ANALYSIS 
INDICATES FAVORABLE CONDITIONS CHARACTERIZED BY MODERATE EQUATORWARD 
OUTFLOW AND WEAK POLEWARD OUTFLOW BEING ENHANCED BY A DEVELOPING OUTFLOW 
CHANNEL INTO A STRONG TUTT-CELL TO THE NORTHEAST. VWS REMAINS LOW (10-
15KT) AND SEA SURFACE TEMPERATURES ARE CONDUCIVE AT A WARM 29-30C. 
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 98W WILL CONTINUE TO GRADUALLY 
CONSOLIDATE AND DEVELOP AS IT TRACKS GENERALLY NORTHWESTWARD OVER THE 
NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
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 UPGRADED TO HIGH. SEE REF A (WTPN22 PGTW 202100) 
FOR FURTHER DETAILS.
      (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: UPGRADED AREA IN PARA. 1.B.(1) TO
HIGH.//
