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:
      (1) AT 17MAY24 1200Z, TROPICAL CYCLONE 24S (IALY) WAS LOCATED NEAR 
8.8S 50.4E, APPROXIMATELY 629 NM NORTH-NORTHEAST OF ANTANANARIVO, 
MADAGASCAR, AND HAD TRACKED WEST- NORTHWESTWARD AT 06 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS 
GUSTING TO 50 KNOTS. SEE REF A (WTXS31 PGTW 171500) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED NEAR 
2.6S 73.1E IS NOW LOCATED NEAR 1.9S 72.9E, APPROXIMATELY 328 NM NORTH OF 
DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY (EIR) AND A 
172128Z GMI 89GHZ MICROWAVE IMAGE DEPICTS A DISORGANIZED ELONGATED LOW 
LEVEL CLOSED CIRCULATION (LLCC). ENVIRONMENTAL ANALYSIS REVEALS A 
MARGINALLY FAVORABLE ENVIRONMENT WITH HIGH (40-50KT) VWS, MODERATE 
STRAIGHT UPPER-LEVEL OUTFLOW, AND WARM (29-30C) SEA SURFACE TEMPERATURES 
(SST). GLOBAL DETERMINISTIC MODELS ARE IN FAIR AGREEMENT THAT INVEST 93S 
WILL CONTINUE TO STRENGTHEN IN THE INDIAN OCEAN OVER THE NEXT 24 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 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 
UPGRADED TO LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED LOW AREA IN PARA. 2.B. (1).//
