1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 14JUL25 0600Z, TROPICAL STORM 06W (NARI) WAS LOCATED 
NEAR 36.8N 142.6E, APPROXIMATELY 167 NM EAST-NORTHEAST OF YOKOSUKA, 
JAPAN, AND HAD TRACKED NORTHWARD AT 27 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS GUSTING TO 
55 KNOTS. SEE REF A (WTPN31 PGTW 140900) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 95W) HAS PERSISTED NEAR 26.0N 
139.5E, APPROXIMATELY 122 NM NORTHWEST OF IWO-TO. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY (EIR) AND A 140901Z SSMIS MICROWAVE IMAGE 
DEPICT A SMALL RAPIDLY CONSOLIDATING LOW-LEVEL CIRCULATION (LLC) WITH 
PERSISTENT CORE CONVECTION. A RECENT 141048Z ASCAT-B PASS REVEALS A 
DEVELOPING CIRCULATION, WITH SHARP CYCLONIC TURNING AND 25-30 KNOT 
WINDS ISOLATED OVER THE EASTERN QUADRANT. THIS SMALL SYSTEM IS 
FORMING ADJACENT TO AN EXTENSIVE REGION OF 20-30 KNOT SOUTHERLY 
WINDS, WHICH EXTENDS POLEWARD AS FAR NORTH AS TS 06W. RECENT 
OBSERVATIONS FROM IWO-TO REVEAL SUSTAINED WINDS OF 16-21 KNOTS 
GUSTING AS HIGH AS 31 KNOTS WITH A SLP OF 1004MB. ENVIRONMENTAL 
ANALYSIS REVEALS LOW TO MODERATE VERTICAL WIND SHEAR (VWS) OF 15-20 
KNOTS, GOOD EQUATORWARD UPPER-LEVEL OUTFLOW AND WARM SEA SURFACE 
TEMPERATURES (SST) OF 28-29 C. DETERMINISTIC AND ENSEMBLE MODELS ARE 
IN AGREEMENT FORECASTING A SMALL RAPIDLY DEVELOPING LLC WITH A 
NORTHWARD TRACK. THESE TYPES OF SMALL SYSTEMS HAVE A TENDENCY TO 
DEVELOP RAPIDLY AND COULD INTENSIFY TO 40-50 KNOTS OR HIGHER WITHIN 
THE NEXT 24 TO 36 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) AT 14JUL25 0000Z, SUBTROPICAL DEPRESSION 07W (SEVEN) WAS 
LOCATED NEAR 32.7N 130.8E, APPROXIMATELY 60 NM EAST-SOUTHEAST OF 
SASEBO, JAPAN, AND HAD TRACKED NORTHEASTWARD AT 15 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 THE 
FINAL WARNING ON THIS SYSTEM.
      (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.
3. JUSTIFICATION FOR REISSUE: ADDED MEDIUM AREA IN PARA. 1.B.(1).//
