1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 29OCT21 0600Z, TROPICAL STORM 25W (MALOU) WAS LOCATED 
NEAR 32.0N 146.7E, APPROXIMATELY 402 NM EAST-SOUTHEAST OF YOKOSUKA, 
JAPAN, AND HAD TRACKED NORTHEASTWARD AT 27 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 60 KNOTS 
GUSTING TO 75 KNOTS. SEE REF A (WTPN31 PGTW 290900 COR) FOR THE 
FINAL WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 90W) HAS PERSISTED NEAR 7.0N 
150.3E, APPROXIMATELY 512 NM SOUTHEAST OF GUAM. ANIMATED ENHANCED 
INFRARED (EIR) SATELLITE IMAGERY AND A 291156Z ASCAT-C IMAGE REVEALS 
EVIDENCE OF A WAVE-LIKE FEATURE APPROXIMATELY 100 NM WSW OF CHUUK, 
ALBEIT A WEAK SIGNATURE. ENVIRONMENTAL ANALYSIS HOWEVER REVEALS THE 
SYSTEM TO BE IN A MARGINALLY FAVORABLE ENVIRONMENT WITH WEAK 
POLEWARD OUTFLOW ALOFT LOW (5-10KT) VERTICAL WIND SHEAR AND WARM (30-
31C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN AGREEMENT THAT 
INVEST 90W WILL CONTINUE TO DEVELOP AND CONSOLIDATE AS IS TRACKS 
NORTHWESTWARD OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW. SEE 
REF A 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: ADDED LOW AREA IN PARA 1.B.(1).//
