1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 25OCT20 0000Z, TROPICAL STORM 19W (SAUDEL) WAS LOCATED 
NEAR 17.6N 109.2E, APPROXIMATELY 109 NM NORTH-NORTHEAST OF DA NANG, 
VIETNAM, AND HAD TRACKED WESTWARD AT 10 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS 
GUSTING TO 55 KNOTS. SEE REF A (WTPN31 PGTW 250300) FOR FURTHER 
DETAILS.
      (2) AT 25OCT20 0000Z, TROPICAL STORM 21W (MOLAVE) WAS LOCATED 
NEAR 13.4N 126.3E, APPROXIMATELY 317 NM EAST-SOUTHEAST OF MANILA, 
PHILIPPINES, AND HAD TRACKED WESTWARD AT 14 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS 
GUSTING TO 70 KNOTS. SEE REF B (WTPN32 PGTW 250300) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 99W) PREVIOUSLY LOCATED 
NEAR 8.3N 153.2E IS NOW LOCATED NEAR 9.5N 149.9E, APPROXIMATELY 383 
NM SOUTHEAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
DEPICTS A BROAD AREA OF TROUGHING WITH FLARING DEEP CONVECTION BEING 
SHEARED TO THE EAST. A 241043Z METOP-A ASCAT PASS REVEALS TIGHT 
TROUGHING WITH A SMALL SWATH OF 20 TO 30 KNOT WINDS ON THE EASTERN 
SIDE. 99W IS CURRENTLY IN A FAVORABLE ENVIRONMENT WITH MODERATE 
EASTWARD UPPER LEVEL OUTFLOW BEING SUPPORTED BY LOW (10 TO 20 KNOT) 
VERTICAL WIND SHEAR AND WARM (30 TO 31 CELSIUS) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS ARE SPLIT WITH ECMWF AND UKMET TRACKING 
99W GENERALLY NORTHWESTWARD WITH LITTLE TO NO INTENSIFICATION. 
HOWEVER, GFS AND NAVGEM SHOW MORE SIGNIFICANT INTENSIFICATION AFTER 
SEVERAL DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 
15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 
MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS REMAINS 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.//
