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) THE AREA OF CONVECTION (INVEST 11S) PREVIOUSLY LOCATED NEAR 
21.3S 382E IS NOW LOCATED NEAR 22.0S 38.0E, APPROXIMATELY 133 NM WEST OF 
EUROPA ISLAND. ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A BROAD LOW-
LEVEL CIRCULATION (LLC) WITH LIMITED CONVECTION OFFSET TO THE 
SOUTHEASTERN PERIPHERY. A 022233Z ATMS 165GHZ MICROWAVE PASS FURTHER 
REVEALS CONVECTIVE BANDING WRAPPING INTO THE SOUTHERN PERIPHERY OF LLC 
FROM THE NORTHEAST. A 021930Z ASCAT-B PARTIAL PASS REVEALS A SWATH OF 25 
KNOT WINDS ALONG THE WESTERN SEMI-CIRCLE OF THE LLC. THE REMNANTS OF 11S 
CURRENTLY SITS IN A FAVORABLE ENVIRONMENT CHARACTERIZED BY ROBUST 
POLEWARD OUTFLOW ALOFT, LOW (10-15KT) VWS, AND WARM (28-29C) SST. GLOBAL 
MODELS CONTINUE TO BECOME MORE AGGRESSIVE WITH THE INTENSIFICATION OF THE 
SYSTEM AS IT TRACKS EASTWARD ACROSS THE MOZAMBIQUE CHANNEL OVER THE NEXT 
24-48 HOURS.  MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO MEDIUM. //
