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 6.4n 91.3e,
has remained quasi-stationary over the past 06 hours, approximately
700 nm east of Colombo, Sri Lanka. Recent animated infrared imagery
and a 021219z SSMI microwave image depict a slowly consolidating
low-level circulation center (LLCC) with weak convective banding.
A 021153z Quikscat image supports the presence of an elongated LLCC
with 20-25 knot unflagged winds near the center. The system
remains in a generally favorable environment with low vertical
wind shear and strong diffluence aloft fueling persistent deep
convection. Maximum sustained surface winds are estimated at 20 to
25 knots and minimum sea level pressure at 1008 mb. Due to the
presence of a developing 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 remains
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.
