1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 20OCT20 0000Z, TROPICAL STORM 19W (SAUDEL) WAS LOCATED 
NEAR 15.6N 124.9E, APPROXIMATELY 234 NM EAST-NORTHEAST OF MANILA, 
PHILIPPINES, AND HAD TRACKED WEST- NORTHWESTWARD AT 13 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED 
AT 35 KNOTS GUSTING TO 45 KNOTS. SEE REF A (WTPN31 PGTW 200300) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED 
NEAR 24.1N 138.8E IS NOW LOCATED NEAR 24.5N 138.4E, APPROXIMATELY 
160 NM WEST OF IWO TO. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND 
A 192151Z SSMIS 91GHZ IMAGE DEPICT A REGION OF DEEP CONVECTION 
OFFSET TO THE EAST OF A WELL DEFINED LOW LEVEL CIRCULATION CENTER. 
INVEST 97W IS IN A MARGINALLY FAVORABLE ENVIRONMENT FOR DEVELOPMENT 
WITH GOOD EQUATORWARD OUTFLOW ALOFT, WARM (29-30C) SEA SURFACE 
TEMPERATURES, ONLY OFFSET BY MODERATE-HIGH (20-30 KNOTS) VERTICAL 
WIND SHEAR. GLOBAL MODELS INDICATE INVEST 97W WILL CONTINUE TO TRACK 
ERRATICALLY POLEWARD WITH SLIGHT INTENSIFICATION OVER THE NEXT 24 
HOURS AS TS 19W MOVES WESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 20 TO 25 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 B (WTPN21 PGTW 200200) 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.//
