RMKS/
1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 98B) HAS PERSISTED NEAR 2.8N 
82.5E, APPROXIMATELY 290 NM SOUTHEAST OF COLUMBO, SRI LANKA. RECENT 
ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS DEEP CONVECTION FLARING 
ON THE NORTHWESTERN PERIPHERY OF A BROAD AND PARTIALLY EXPOSED LOW 
LEVEL CIRCULATION CENTER. UPPER-LEVEL ANALYSIS INDICATES MODERATE TO 
STRONG (15-25 KTS) EASTERLY VERTICAL WIND SHEAR (VWS) WITH STRONG 
WESTWARD AND POLEWARD DIVERGENCE ALOFT. SEA SURFACE TEMPERATURES (27-
28C) ARE CONDUCIVE, BUT VWS IS EXPECTED TO REMAIN MODERATE TO STRONG 
AND PREVENT DEVELOPMENT IN THE NEAR TERM AS THE SYSTEM TRACKS WESTWARD 
INTO THE ARABIAN SEA OVER THE NEXT SEVERAL DAYS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 1008 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.
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 96S) HAS PERSISTED NEAR 8.9S 
78.7E, APPROXIMATELY 380 NM EAST-SOUTHEAST OF DIEGO GARCIA.  RECENT 
ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS DEEP CONVECTION 
PERSISTING ALONG THE WESTERN AND NORTHERN PERIPHERIES OF A DEVELOPING 
LOW LEVEL CIRCULATION CENTER. THE CIRCULATION IS PASSING OVER VERY 
WARM WATER (27-28C) BUT CURRENTLY LIES IN AN AREA OF MODERATE TO 
STRONG (15-20 KTS) EASTERLY VERTICAL WIND SHEAR AND IS EXPECTED TO 
TRACK EQUATORWARD INTO A ZONE OF HIGHER SHEAR OVER THE NEXT FEW DAYS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 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 LOW.
     (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADD LOW AREAS IN PARA 1.B.(1) AND 2.B.
(1).//
