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 05JAN26 1800Z, TROPICAL CYCLONE 12S (JENNA) WAS LOCATED 
NEAR 14.4S 96.1E, APPROXIMATELY 140 NM SOUTH-SOUTHWEST OF THE COCOS 
ISLANDS, AND HAD TRACKED SOUTH- SOUTHWESTWARD AT 12 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 65 
KNOTS GUSTING TO 80 KNOTS. SEE REF A (WTXS31 PGTW 052100) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (REMNANTS 09S) HAS PERSISTED NEAR 
17.2S 53.0E, APPROXIMATELY 214 NM EAST-NORTHEAST OF TOAMASINA, 
MADAGASCAR. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY (EIR) AND A 
052137Z GMI 89GHZ MICROWAVE PASS DEPICT AN OBSCURED LOW-LEVEL 
CIRCULATION CENTER (LLCC) WITH PERSISTENT CONVECTION AND OVERSHOOTING 
TOPS DIRECTLY OVER THE CENTER. A RECENT OBSERVATION FROM TROMELIN 
ISLAND INDICATES NORTHEASTERLY WINDS AT 16 KNOTS AND A SLP OF 1010MB. 
ENVIRONMENTAL ANALYSIS REVEALS A MODERATE ENVIRONMENT FOR DEVELOPMENT 
WITH LOW VERTICAL WIND SHEAR (VWS) OF 15-20 KNOTS, WEAK UPPER-LEVEL 
OUTFLOW, AND WARM SEA SURFACE TEMPERATURES (SST) OF 28-29C. GLOBAL 
MODELS ARE IN GOOD AGREEMENT THAT THE REMNANTS OF 09S WILL CONTINUE 
TO VACILLATE BETWEEN 30-35 KTS SYSTEM TRACKS WEST-SOUTHWEST TOWARD 
THE EASTERN COAST OF MADAGASCAR OVER THE NEXT 48 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 33 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 UPGRADED TO MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA (REMNANTS 09S) IN PARA. 
2.B.(1) TO MEDIUM.//
