1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 02OCT22 0000Z, TROPICAL STORM 20W (ROKE) WAS LOCATED NEAR 
36.3N 152.5E, APPROXIMATELY 585 NM EAST- SOUTHEAST OF MISAWA, JAPAN, 
AND HAD TRACKED EAST-NORTHEASTWARD AT 21 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS 
GUSTING TO 70 KNOTS. SEE REF A (WTPN33 PGTW 020300) FOR THE FINAL 
WARNING ON THIS SYSTEM. TS 20W IS CURRENTLY CLASSIFIED AS A 
SUBTROPICAL CYCLONE. SEE PARA 1.C.(1) FOR CURRENT INFORMATION AND THE 
POTENTIAL TO TRANSITION BACK INTO A TROPICAL CYCLONE.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (REMNANTS 20W) PREVIOUSLY LOCATED 
NEAR 36.3N 152.5E IS NOW LOCATED NEAR 37.0N 154.8E, APPROXIMATELY 648 
NM EAST OF MISAWA, JAPAN. THE SYSTEM IS CURRENTLY CLASSIFIED AS A 
SUBTROPICAL STORM, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND 
MID-LATITUDE CYCLONE FEATURES. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) AND A 020318Z AMSR2 89GHZ PASS DEPICT AN ASYMMETRIC 
CONVECTIVE STRUCTURE WITH PARTIALLY EXPOSED LOW LEVEL CIRCULATION 
CENTER (LLCC) THAT IS TRANSITING EAST-NORTHEASTWARD ALONG THE 
NORTHWEST PERIPHERY OF A DEEP SUBTROPICAL RIDGE (STR) TO THE 
SOUTHEAST. ENVIRONMENTAL CONDITIONS REVEAL UNFAVORABLE CONDITIONS FOR 
TRANSITIONING INTO A TROPICAL CYCLONE WITH SEVERE (40-50KTS) VWS, COOL 
(25C) SSTS, AND THE PRESENCE OF A SHARP UPPER-LEVEL TROUGH DISPLACED 
JUST TO THE WEST OF THE LLCC. GLOBAL MODELS AGREE THAT THE REMNANTS OF 
20W WILL SLOWLY MOVE EAST-NORTHEASTWARD AND BECOME QUASI-STATIONARY 
AFTER TAU 24 AS THE SYSTEM SLOWLY DISSIPATES OVER OPEN WATER.   
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 52 TO 58 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 992 MB. FOR HAZARDS 
AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS 
AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
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.//
