1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA)
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR 
5.7N 146.1E IS NOW LOCATED NEAR 5.4N 149.5E, APPROXIMATELY 184 NM 
SOUTHWEST OF CHUUK, MICRONESIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
AND A 180424Z 89GHZ AMSR2 PARTIAL PASS REVEAL DISORGANIZED, DEEP FLARING 
CONVECTIVE LINES TO THE SOUTH OF A BROAD AND ELONGATED LOW LEVEL 
CIRCULATION CENTER (LLCC), WITH HINTS AT MULTIPLE AREAS OF VORTICITY 
ROTATING ALONG THE TROUGH AXIS. THE 180000Z BEST TRACK POSITION HAS BEEN 
SHIFTED EAST TO A CENTROID POSITION BETWEEN THE TWO MOST EASTWARD OF THE 
VORTICITY CENTERS AS SEEN IN BOTH THE ANIMATED VISIBLE IMAGERY AND THE 
PARTIAL ASCAT-B PASS NOTED ABOVE. ENVIRONMENTAL ANALYSIS SHOWS THAT THE 
SYSTEM IS CURRENTLY IN A FAVORABLE ENVIRONMENT DUE TO WARM (30-31C) SST, 
LOW (10-15KT) VWS AND GOOD EQUATORWARD OUTFLOW. DETERMINISTIC MODELS AGREE 
THAT 97W WILL CONTINUE CONSOLIDATE WHILE MOVING IN A GENERAL NORTH-
NORTHWESTWARD TRAJECTORY, THOUGH THE ENSEMBLE GUIDANCE (GEFS AND ECENS) 
DEPICT A VERY LARGE AMOUNT OF SPREAD, INDICATIVE OF THE UNCERTAINTY IN THE 
INITIAL POSITION AND HIGH UNCERTAINTY IN THE FORECAST TRACK. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 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 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: RELOCATED AREA IN PARA 1.B.(1) APPROXIMATELY 
240NM EAST OF PREVIOUS LOCATION.//
