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 08MAR25 0600Z, TROPICAL CYCLONE 24S (TWENTYFOUR) WAS 
LOCATED NEAR 11.9S 84.7E, APPROXIMATELY 777 NM EAST-SOUTHEAST OF DIEGO 
GARCIA, AND HAD TRACKED SOUTH- SOUTHWESTWARD AT 09 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS 
GUSTING TO 45 KNOTS. SEE REF A (WTXS31 PGTW 080900) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 99S) PREVIOUSLY LOCATED NEAR 
13.1S 51.8E IS NOW LOCATED NEAR 13.9S 49.3E, APPROXIMATELY 369 NM 
EAST-SOUTHEAST OF COMOROS, AFRICA. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY (EIR) DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION 
CENTER (LLCC) ASSOCIATED WITH IMPROVED CONVECTIVE BANDING WRAPPING IN. 
A PARTIAL 072304Z METOP-B SCATTEROMETER IMAGE SHOWS SWATH OF 30 KTS 
ASSOCIATED WITH THE BANDING IN THE EASTERN SEMICIRCLE. ENVIRONMENTAL 
CONDITIONS ARE CURRENTLY MARGINALLY FAVORABLE DUE TO GOOD POLEWARD 
OUTFLOW ALOFT AND LOW TO MODERATE (15-20 KTS) VERTICAL WIND SHEAR, BUT 
IS OFFSET DUE TO LAND INTERACTION AS THE SYSTEM TRANSITS NORTHERN 
MADAGASCAR. GLOBAL MODELS ARE IN GOOD AGREEMENT THE 99S WILL CONTINUE 
TO CONSOLIDATE OVER THE NEXT 24 HOURS DUE TO INTERACTING WITH WARM SEA 
SURFACE TEMPERATURES (28-29C) IN THE MOZAMBIQUE CHANNEL. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1001 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS HIGH. SEE REF B (WTXS22 PGTW 080400) FOR FURTHER DETAILS.
      (2) THE AREA OF CONVECTION (INVEST 98S) PREVIOUSLY LOCATED NEAR 
11.9S 84.7E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE 
PARA. 2.A.(1) FOR FURTHER DETAILS.
      (3) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(2) TO WARNING 
STATUS.//
