1. Western North Pacific area (180 to Malay Peninsula):
   a. Tropical cyclone summary: none.
   B. Tropical disturbance summary:
      (1) the area of convection previously located near 6.5n
110.7e, is now located near 5.9n 109.7e, approximately 340 nm south-
southeast of Ho Chi Minh, Vietnam. Animated multispectral satellite
imagery and a 040221z AMSU-b image indicates a developing low level
circulation center (LLCC) has begun to reconsolidate with increasing
deep convection in the northwest quadrant of the LLCC. Recent
scatterometer data depicts strong northeasterly flow beginning to
wrap into the LLCC with convergent flow north and northwest of the
LLCC, which is continuing to produce deep convective bursts, with a
well defined 15-20 knot LLCC. The LLCC appears to be tracking
westsouthwestward while convection is shearing westward to
northwestward under strong diffluent upper-level flow. The system
has been able to maintain a well consolidated LLCC with cyclic deep
convection.  Maximum sustained surface winds are estimated at 15 to
20 knots. Minimum sea level pressure is estimated to be near 1004
mb. 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 Pacific area (west coast of South America to 135 east):
   a. Tropical cyclone summary: none.
   B. Tropical disturbance summary: none.
