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 15JAN25 1800Z, TROPICAL CYCLONE 07S (DIKELEDI) WAS 
LOCATED NEAR 25.7S 42.3E, APPROXIMATELY 239 NM SOUTH-SOUTHEAST OF 
EUROPA ISLAND, AND HAD TRACKED SOUTH- SOUTHEASTWARD AT 19 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 
85 KNOTS GUSTING TO 105 KNOTS. SEE REF A (WTXS31 PGTW 152100) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 90S) HAS PERSISTED NEAR 18.0S 
112.4E, APPROXIMATELY 288 NM NORTH-NORTHWEST OF LEARMONTH, AUSTRALIA. 
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 152220Z SSMIS 89GHZ 
MICROWAVE IMAGE DEPICT AN AREA OF CIRCULATION WITH A PARTIALLY EXPOSED 
LLCC WITH DEEP CYCLING CONVECTION PRIMARILY ALONG THE SOUTHERN 
PERIPHERY OF THE CIRCULATION. A 151427Z ASCAT METOP-B PASS INDICATES A 
CONSOLIDATING CIRCULATION WITH STRONGER WINDS (20KTS) WRAPPING INTO 
THE CENTER. ENVIRONMENTAL ANALYSIS INDICATES FAVORABLE CONDITIONS FOR 
DEVELOPMENT WITH LOW TO MODERATE SHEAR (15-20KTS), MODERATE DIVERGENCE 
ALOFT, BACKGROUND LOW-LEVEL VORTICITY AND MOISTURE ASSOCIATED WITH THE 
MONSOON TROUGH, AND WARM SEA SURFACE TEMPERATURES (27-28C). GLOBAL 
DETERMINISTIC MODELS AND ENSEMBLE SYSTEMS INDICATE THAT THIS SYSTEM 
WILL MOVE EASTWARD OVER THE NEXT COUPLE OF DAYS AND POTENTIALLY 
INTERACT WITH OR MERGE WITH A SEPARATE CIRCULATION IN THE VICINITY OF 
BROOME, AUSTRALIA BEFORE ULTIMATELY TURNING SOUTHWESTWARD OFFSHORE OF 
WESTERN AUSTRALIA. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 
TO 23 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: ADDED LOW AREA IN PARA 2.B(1).//
