1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 28OCT20 0600Z, TYPHOON 21W (MOLAVE) WAS LOCATED NEAR 
15.4N 108.5E, APPROXIMATELY 38 NM SOUTH-SOUTHEAST OF DA NANG, 
VIETNAM, AND HAD TRACKED WEST-NORTHWESTWARD AT 14 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 70 
KNOTS GUSTING TO 85 KNOTS. SEE REF A (WTPN32 PGTW 280900) FOR THE 
FINAL WARNING ON THIS SYSTEM.
      (2) AT 28OCT20 1200Z, TROPICAL STORM 22W (TWENTYTWO) WAS 
LOCATED NEAR 16.6N 138.7E, APPROXIMATELY 1030 NM EAST OF MANILA, 
PHILIPPINES, AND HAD TRACKED WESTWARD AT 08 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS 
GUSTING TO 45 KNOTS. SEE REF B (WTPN31 PGTW 281500) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED 
NEAR 6.0N 151.0E IS NOW LOCATED NEAR 6.7N 149.5E, APPROXIMATELY 146 
NM WEST-SOUTHWEST OF CHUUK, FSM. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY AND A 281527Z AMSR2 89GHZ IMAGE DEPICT A 
CONSOLIDATING LOW LEVEL CIRCULATION WITH FRAGMENTED FORMATIVE 
BANDING AND DEEP CONVECTION IN THE SOUTHERN SEMICIRCLE. INVEST 90W 
IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH GOOD EQUATORWARD 
OUTFLOW, LOW (<15KTS) VERTICAL WIND SHEAR, AND WARM (30-31C) SEA 
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN STRONG AGREEMENT THAT 
INVEST 90W WILL CONTINUE TO CONSOLIDATE AND INTENSIFY AS IT TRACKS 
NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 
TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 
MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
      (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 
MEDIUM.//
