1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 06JUL22 1800Z, TROPICAL STORM 05W (AERE) WAS LOCATED NEAR 
33.8N 144.4E, APPROXIMATELY 249 NM EAST-SOUTHEAST OF YOKOSUKA, JAPAN, 
AND HAD TRACKED EASTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 
KNOTS. SEE REF A (WTPN31 PGTW 062100) FOR THE FINAL WARNING ON THIS 
SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (REMNANTS 05W) PREVIOUSLY LOCATED 
NEAR 34.3N 144.6E IS NOW LOCATED NEAR 37.3N 144.9E, APPROXIMATELY 
282 NM EAST-NORTHEAST OF TOKYO JAPAN. THE SYSTEM IS CURRENTLY 
CLASSIFIED AS A SUBTROPICAL STORM, GENERALLY CHARACTERIZED AS HAVING 
BOTH TROPICAL AND MID-LATITUDE CYCLONE FEATURES. AN ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 090301Z AMSR2 89GHZ IMAGE 
DEPICT DEEP CONVECTION SHEARED TO THE NORTH OF AN EXPOSED AND 
ELONGATED LOW LEVEL CIRCULATION CENTER (LLCC). A PARTIAL 090059Z ASCAT 
METOP-B PASS REVEALS 25-30KT WINDS IN THE NORTHERN SECTOR OF THE LLCC. 
ENVIRONMENTAL ANALYSIS INDICATES A MARGINALLY FAVORABLE ENVIRONMENT 
WITH COOL (23C) SEA SURFACE TEMPERATURES, OFFSET BY LOW (5-10KT) 
VERTICAL WIND SHEAR AND GOOD POLEWARD AND EQUATORWARD OUTFLOW ALOFT, 
WHICH IS CONDUCIVE FOR TROPICAL TRANSITION. GLOBAL MODELS ARE IN TIGHT 
AGREEMENT THAT REMNANTS 05W WILL HAVE AN ASYMMETRIC WIND FIELD AS IT 
TRACKS NORTHWESTWARD TOWARDS SOUTHERN HOKKAIDO.  MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS BASED ON DVORAK 
ESTIMATES FROM PGTW ST1.5(25KTS). MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 997 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 SYSTEM TO TRANSITION INTO 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.
