1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 22JUN26 0600Z, TYPHOON 07W (MEKKHALA) WAS LOCATED NEAR 
17.9N 126.9E, APPROXIMATELY 518 NM SOUTH OF KADENA AB, AND HAD TRACKED 
WEST-NORTHWESTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 115 KNOTS GUSTING TO 140 
KNOTS. SEE REF A (WTPN31 PGTW 220900) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR 
14.3N 149.3E IS NOW LOCATED NEAR 14.5N 147.7E, APPROXIMATELY 188 NM 
EAST-NORTHEAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC) WITH 
PERSISTENTLY BUILDING DEEP CONVECTION OVER THE CENTER. PREVIOUS ANALYSIS 
REVEALED THAT 94W WAS COMPRISED OF MOSTLY MID-LEVEL ROTATION, HOWEVER, 
RECENTLY, THE DISTURBANCE HAS FORMED A WEAK AND BROAD SURFACE 
CIRCULATION. ENVIRONMENTAL ANALYSIS SHOWS A FAVORABLE AREA FOR 
DEVELOPMENT WITH LOW (5-10 KTS) VERTICAL WIND SHEAR, WARM (30 C) SEA 
SURFACE TEMPERATURES (SST), AND MODERATE POLEWARD OUTFLOW WITHIN THE 
UPPER LEVELS. DETERMINISTIC AND ENSEMBLE MODELS SHOW GRADUAL DEVELOPMENT 
OVER THE NEXT 24-36 HOURS AS THE SYSTEM TRACKS OVER THE MARIANAS 
ISLANDS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1009 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF B (WTPN21 PGTW 221100) 
FOR FURTHER DETAILS.
      (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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 1.B.(1) TO HIGH.//
