   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 18APR25 1200Z, TROPICAL CYCLONE 29S (ERROL) WAS LOCATED 
NEAR 16.0S 124.5E, APPROXIMATELY 174 NM NORTHEAST OF BROOME, AUSTRALIA, 
AND HAD TRACKED EASTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS GUSTING TO 40 KNOTS. 
SEE REF A (WTXS31 PGTW 181500) FOR THE FINAL WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 99S) PREVIOUSLY LOCATED NEAR 
13.0S 71.7E IS NOW LOCATED NEAR 14.4S 71.3E, APPROXIMATELY 430 NM SOUTH 
OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY 
DEPICT A POORLY ORGANIZED AND BROAD LOW-LEVEL CIRCULATION CENTER (LLCC) 
WITH AN AREA OF FLARING CONVECTION WITHIN THE SOUTHEASTERN QUADRANT. 
ENVIRONMENTAL ANALYSIS REVEALS A MARGINALLY FAVORABLE ENVIRONMENT FOR 
DEVELOPMENT WITH MODERATE TO HIGH (20-25 KNOTS) VERTICAL WIND SHEAR, 
GOOD POLEWARD OUTFLOW, AND WARM (28-29 C) SEA SURFACE TEMPERATURES. 
DETERMINISTIC AND ENSEMBLE MODELS ARE IN FAIR AGREEMENT, SHOWING GRADUAL 
WEAKENING IN THE SOUTH INDIAN OCEAN OVER THE NEXT 48 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 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: UPDATED PARA. 2.A.(1) WITH 29S (ERROL)
