1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (REMNANTS 20W) PREVIOUSLY LOCATED NEAR 
37.0N 154.8E IS NOW LOCATED NEAR 36.8N 158.1E, APPROXIMATELY 817 NM EAST-
SOUTHEAST 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), A 030223Z AMSR2 89GHZ PASS, AND A 022250Z ASCAT-C PASS DEPICT A T-
BONE FRONTAL SYSTEM STRUCTURE WITH A FULLY EXPOSED LOW LEVEL CIRCULATION 
CENTER (LLCC) STALLED ALONG THE SOUTHERN PERIPHERY OF A TRANSIENT HIGH 
PRESSURE SYSTEM. THE SCATTEROMETER DATA INDICATED AN ASYMMETRIC WIND 
FIELD WITH GALE-FORCE WINDS EXTENDING FROM THE SOUTHWEST TO NORTHEAST OF 
THE SYSTEM AND LIGHTER WINDS ELSEWHERE. ENVIRONMENTAL CONDITIONS ARE 
UNFAVORABLE FOR TRANSITIONING INTO A TROPICAL CYCLONE WITH STRONG (40-
50KTS) VWS, COOL (25C) SSTS, AND THE PRESENCE OF A STJ MAX SLICING 
THROUGH THE EASTERN PORTION OF THE SYSTEM WHICH WILL ULTIMATELY CAUSE THE 
SYSTEM TO FILL AND GRADUALLY DISSIPATE UNTIL BEING ABSORBED AND CARRIED 
OFF BY A DEVELOPING LOW PRESSURE SYSTEM IN THE SEA OF OKHOTSK. GLOBAL 
MODELS AGREE THAT THE REMNANTS OF 20W WILL CONTINUE ITS QUASI-STATIONARY 
TRACK AFTER TAU 24 AS THE SYSTEM TROUGHS OUT AND GET PICKED UP BY A 
FOLLOW ON LOW PRESSURE SYSTEM. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 42 TO 48 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.//
