RMKS/ 
1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA): 
   A. TROPICAL CYCLONE SUMMARY: NONE. 
   B. TROPICAL DISTURBANCE SUMMARY: NONE. 
   C. SUBTROPICAL SYSTEM SUMMARY: NONE. 
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA): 
   A. TROPICAL CYCLONE SUMMARY: NONE. 
   B. TROPICAL DISTURBANCE SUMMARY: 
      (1) AN AREA OF CONVECTION (INVEST 98S) HAS PERSISTED NEAR 10.5S 
96.2E, APPROXIMATELY 108 NM NORTH-NORTHWEST OF COCOS ISLAND. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY AND A 130615Z GOES-13 IMAGE DEPICT A 
FULLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH CONVECTION SHEARED 
TO THE SOUTHWEST. UPPER-LEVEL ANALYSIS INDICATES 98S IS IN A FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT WITH LOW TO MODERATE (10-15KT) VWS OFFSET BY 
STRONG DIVERGENCE ALOFT AND WARM (28-29C) SEA SURFACE TEMPERATURES. 
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 98S WILL CONTINUE TO TRACK 
WESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS IS LOW. 
      (2) NO OTHER SUSPECT AREAS. 
   C. SUBTROPICAL SYSTEM SUMMARY: NONE. 
3. JUSTIFICATION FOR REISSUE: ADDED LOW AREA IN PARA.2.B.(1).////
