1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 3.0N 92.8E,
IS NOW LOCATED NEAR 6.4N 91.3E, APPROXIMATELY 685 NM EAST OF COLOMBO,
SRI LANKA. RECENT ANIMATED METSAT IMAGERY AND A 021219Z SSMI MICROWAVE
PASS DEPICT DEVELOPING DEEP CONVECTION BEGINNING TO WRAP INTO AN ELON-
GATED BUT CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC). A 021153Z
QUIKSCAT IMAGE SUPPORTS THE PRESENCE OF THE LLCC AND SHOWS 15-25 KNOT
UNFLAGGED WINDS NEAR THE CENTER. THE SYSTEM REMAINS FAIRLY ELONGATED,
BUT HAS FAVORABLE DIFFLUENCE ALOFT WITH MODERATE VERTICAL WIND SHEAR
IN THE REGION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO
23 KNOTS AND MINIMUM SEA LEVEL PRESSURE AT 1007 MB. DUE TO THE PRESENCE
OF A DEVLOPING LLCC WITH CONVECTIVE BANDING BEGINNING TO WRAP INTO THE
CENTER, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO FAIR.
      (2) NO OTHER SUSPECT AREAS.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
