1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 14OCT22 0000Z, TROPICAL STORM 21W (TWENTYONE) WAS 
LOCATED NEAR 18.5N 156.0E, APPROXIMATELY 618 NM EAST-NORTHEAST OF 
SAIPAN, AND HAD TRACKED NORTH-NORTHEASTWARD AT 20 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS 
GUSTING TO 45 KNOTS. SEE REF A (WTPN31 PGTW 140300) FOR FURTHER 
DETAILS.
      (2) AT 14OCT22 0000Z, TROPICAL DEPRESSION 22W (TWENTYTWO) WAS 
LOCATED NEAR 13.3N 112.4E, APPROXIMATELY 288 NM SOUTHEAST OF DA NANG, 
VIETNAM, AND HAD TRACKED NORTHWESTWARD AT 05 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS 
GUSTING TO 35 KNOTS. SEE REF B (WTPN32 PGTW 140300) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR 
20.1N 130.2E IS NOW LOCATED NEAR 19.5N 129.1E, APPROXIMATELY 428 NM 
EAST OF APARRI, PHILIPPINES. ANIMATED SATELLITE IMAGERY DEPICTS 
FLARING DEEP CONVECTION WRAPPING INTO THE WESTERN AND NORTHERN 
PERIPHERIES OF A CONSOLIDATING LOW LEVEL CIRCULATION. A 140030Z 
ASCAT-B IMAGE REFLECTS A SWATH OF 20-25KT WINDS OVER THE WESTERN 
SEMI-CIRCLE. ENVIRONMENTAL CONDITION ARE FAVORABLE WITH MODERATE 
EQUATORWARD OUTFLOW, STRONG POLEWARD OUTFLOW ALOFT, LOW (10-15KT) 
VWS, AND WARM (29-30C) SST. NUMERICAL MODELS ARE IN AGREEMENT 97W 
WILL CONTINUE DEEPENING AS IT TRACKS WEST THROUGH THE LUZON STRAIT. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH.
      (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.//
