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 10JAN25 1800Z, TROPICAL CYCLONE 07S (DIKELEDI) WAS LOCATED 
NEAR 13.3S 54.2E, APPROXIMATELY 445 NM NORTH-NORTHWEST OF PORT LOUIS, 
MAURITIUS, AND HAD TRACKED WESTWARD AT 14 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS GUSTING TO 70 
KNOTS. SEE REF A (WTXS31 PGTW 102100) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97S) PREVIOUSLY LOCATED NEAR 
17.4S 103.5E IS NOW LOCATED NEAR 17.7S 103.3E, APPROXIMATELY 499 NM 
NORTHWEST OF THE COCOS ISLANDS. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY DEPICTS A LOW LEVEL CIRCULATION CENTER THAT HAS BECOME EXPOSED 
AND SEPARATED FROM ANY DEEP CONVECTION. ENVIRONMENTAL ANALYSIS REVEALS 
MARGINALLY FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL WIND 
SHEAR (10-15 KNOTS), WARM (29-30C) SEA SURFACE TEMPERATURES, OFFSET BY 
WEAK OUTFLOW ALOFT. THERE HAS BEEN AN INCREASE IN DRY AIR ENTRAINMENT 
INTO 97S CAUSING THE SYSTEM TO WEAKEN AND THE LIKELIHOOD OF DEVELOPMENT 
TO DECREASING. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 38 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 997 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS IS DOWNGRADED TO LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: DOWNGRADED AREA IN PARA. 2.B.(1) TO 
LOW.//
