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 01JAN21 1800Z, TROPICAL CYCLONE 08S (DANILO) WAS 
LOCATED NEAR 11.2S 72.1E, APPROXIMATELY 247 NM SOUTH OF DIEGO 
GARCIA, AND HAD TRACKED NORTH-NORTHEASTWARD AT 04 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 
KNOTS GUSTING TO 50 KNOTS. SEE REF A (WTXS31 PGTW 012100) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED 
NEAR 14.8S 81.2E IS NOW LOCATED NEAR 14.7S 80.8E, APPROXIMATELY 662 
NM SOUTHEAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY AND A 011935Z AMSR2 89GHZ MICROWAVE IMAGE DEPICT FLARING 
CONVECTION WRAPPING AROUND A BROAD LOW LEVEL CIRCULATION CENTER 
(LLCC). A 011543Z ASCAT-C PARTIAL PASS REVEALS SOME 25KT WINDS IN 
THE EASTERN SEMICIRCLE. INVEST 93S IS IN A FAVORABLE ENVIRONMENT FOR 
DEVELOPMENT WITH GOOD OUTFLOW ALOFT, LOW (< 15 KTS) VERTICAL WIND 
SHEAR AND WARM (28-29C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE 
IN GENERAL AGREEMENT THAT INVEST 93S WILL TRACK GENERALLY 
SOUTHWESTWARD WITH MINIMAL INTENSIFICATION OVER THE NEXT 24 HOURS 
AND MAY BEGIN TO INTERACT AND BE ABSORBED BY INVEST 96S. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 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 MEDIUM.
      (2) THE AREA OF CONVECTION (INVEST 96S) PREVIOUSLY LOCATED 
NEAR 11.3S 72.1E 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.//
