1.  WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA) :
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 30MAY24 1800Z, TROPICAL STORM 01W (EWINIAR) WAS LOCATED NEAR 
31.7N 138.5E, APPROXIMATELY 224 NM SOUTH-SOUTHWEST OF YOKOSUKA, JAPAN, 
AND HAD TRACKED NORTHEASTWARD AT 21 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS GUSTING TO 55 
KNOTS. SEE REF A (WTPN31 PGTW 302100) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR 
17.9N 113.4E IS NOW LOCATED NEAR 17.5N 112.4E, APPROXIMATELY 181 NM 
SOUTHEAST OF HAIKAOU. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY 
DEPICTS A CONSOLIDATED LLCC WITH DEEP CONVECTION BUILDING OVER THE CENTER 
AND A 301356Z PARTIAL METOP-B ASCAT IMAGE DEPICTING A SYMMETRICAL 
CIRCULATION. ANALYSIS OF THE ENVIRONMENT IS FAVORABLE DUE TO LOW VERTICAL 
WIND SHEAR (10-15KTS), WARM SEA SURFACE TEMPERATURES (29-30C), AND GOOD 
UPPER-LEVEL DIVERGENCE.  DEVELOPMENT FOR THIS SYSTEM IS  LIMITED BY THE 
PROXIMITY OF THE AREA OF CONVECTION TO MAINLAND CHINA, BUT THE AMERICAN 
MODEL SHOWS DEVELOPMENT OVER THE NEXT 24 HOURS.   MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE 
IS ESTIMATED TO BE NEAR 998 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
HIGH.
      (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.//
