1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA)
  A. TROPICAL CYCLONE SUMMARY:
      (1) AT 12JUL25 0000Z, TROPICAL STORM 06W (SIX) WAS LOCATED NEAR 
25.2N 140.5E, APPROXIMATELY 50 NM WEST-NORTHWEST OF IWO TO, AND HAD 
TRACKED EASTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 
KNOTS. SEE REF A (WTPN31 PGTW 120300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
  B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
26.4N 126.7E IS NOW LOCATED NEAR 30.5N 123.6E, APPROXIMATELY 117 NM 
WEST OF SHANGHAI, CHINA. INVEST 92W 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 SUSPECT AREAS.
  C. SUBTROPICAL SYSTEM SUMMARY: 
      (1) ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) IMAGERY 
DEPICTS A FULLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC), WITH 
PERSISTENT FLARING CONVECTION ALONG THE EASTERN AND SOUTHERN 
PERIPHERY OF THE CIRCULATION. A PARTIAL 120038Z ASCAT-B PASS REVEALS 
A BROAD, ELONGATED, AND ASYMMETRIC CYCLONE WITH STRONG WINDS WRAPPING 
AROUND THE CIRCULATION. ENVIRONMENTAL ANALYSIS SHOWS MARGINAL TO 
FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW (10-15 KNOTS) VWS, GOOD 
TO MODERATE OUTFLOW AND WARM (27-28 C) SEA SURFACE TEMPERATURE. 
GLOBAL MODELS ARE IN AGREEMENT THAT INVEST 92W WILL TAKE A 
NORTHEASTERN TRACK INTO COLDER WATERS OVER THE NEXT 24-36 HOURS. FOR 
HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO 
HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST 
AUTHORITY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 22 TO 28 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
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: UPGRADED INVEST 92W TO MEDIUM AND ADDED 
SUBTROPICAL CYCLONE INFORMATION TO PARA 1.C.(1).//
