1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 27JUN26 0000Z, TROPICAL STORM 08W (HIGOS) WAS LOCATED 
NEAR 36.4N 142.9E, APPROXIMATELY 169 NM EAST-NORTHEAST OF YOKOSUKA, 
JAPAN, AND HAD TRACKED EAST-NORTHEASTWARD AT 50 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS 
GUSTING TO 55 KNOTS. SEE REF A (WTPN32 PGTW 270300) FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (2) AT 27JUN26 0000Z, TROPICAL STORM 07W (MEKKHALA) WAS LOCATED 
NEAR 31.6N 133.2E, APPROXIMATELY 394 NM WEST-SOUTHWEST OF YOKOSUKA, 
JAPAN, AND HAD TRACKED NORTHEASTWARD AT 26 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS 
GUSTING TO 45 KNOTS. SEE REF A (WTPN31 PGTW 270300) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR 
5.4N 168.1W IS NOW LOCATED NEAR 4.8N 167.9W, APPROXIMATELY 220 NM 
SOUTH OF KWAJALEIN ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A 
BROAD AREA OF DISORGANIZED CONVECTION WITH A WESTERLY WIND BURST TO 
THE SOUTH OF THE LOW LEVEL CIRCULATION CENTER (LLCC). ENVIRONMENTAL 
ANALYSIS REVEALS A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH LOW 
VERTICAL WIND SHEAR, MODERATE POLEWARD OUTFLOW ALOFT, AND WARM SEA 
SURFACE TEMPERATURES (29-30C). GLOBAL MODELS DEPICT A QUASISTATIONARY 
CIRCULATION THAT REMAINS BROAD WITH GRADUAL DEVELOPMENT OVER THE NEXT 
48-72 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 
18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
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.//
