1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 30JUN22 0000Z, TROPICAL STORM 04W (CHABA) WAS LOCATED NEAR 
15.4N 115.2E, APPROXIMATELY 340 NM WEST OF MANILA, PHILIPPINES, AND HAD 
TRACKED NORTHEASTWARD 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 300300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED NEAR 
17.8N 129.2E IS NOW LOCATED NEAR 18.2N 131.4E, APPROXIMATELY 632 NM EAST-
NORTHEAST OF MANILA, PHILIPPINES. ENHANCED MULTISPECTRAL SATELLITE 
IMAGERY AND A 292156Z SSIMIS 91GHZ PASS DEPICTS A CONVECTIVE BANDING 
OFFSET TO THE SOUTH OF A BROAD, ILL DEFINED LOW LEVEL CIRCULATION (LLC). 
A TUTT CELL LOCATED SOUTHWEST OF SASEBO, JAPAN HAS TRACKED TO THE WEST 
WHICH IS INTRODUCING AN AREA OF UPPER LEVEL DIVERGENCE OVER INVEST 98W, 
FURTHER INCREASING INSTABILITY. ENVIRONMENTAL ANALYSIS INDICATES 
FAVORABLE CONDITIONS FOR DEVELOPMENT DEFINED BY; MODERATE EQUATORWARD 
OUTFLOW ALOFT, LOW (10-15KT) VERTICAL WIND SHEAR, AND WARM (30C) SEA 
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN STRONG AGREEMENT THAT 98W WILL 
TRACK NORTHWESTWARD AS IT BEGINS TO DEVELOP OVER THE NEXT 24-48 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM 
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS 
UPGRADED TO MEDIUM.
      (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 MEDIUM.
