1. North Indian Ocean area (Malay Peninsula west to coast of Africa):
   a. Tropical cyclone summary: none.
   B. Tropical disturbance summary: none.
2. South Indian Ocean area (135e west to coast of Africa):
   a. Tropical cyclone summary:
      (1) at 261800z, tropical cyclone 08s (eight) was located near 
17.1s 78.1e, approximately 684 nm south-southeast of Diego Garcia, 
and had tracked west-southwestward at 06 knots over the past six 
hours. Maximum sustained surface winds were estimated at 35 knots 
gusting to 45 knots. See ref a (wtxs31 pgtw 262100) for further 
details.
      (2) no other tropical cyclones.
   B. Tropical disturbance summary:
      (1) the area of convection previously located near 14.5s 
65.4e, is now located near 14.6s 64.0e, approximately 672 nm 
southwest Diego Garcia. Animated enhanced infrared satellite imagery 
shows a partially-exposed low level circulation center with flaring 
and fragmented convection. Upper-level analysis indicates the 
disturbance is located in a favorable environment with low (05 to 10 
knot) vertical wind shear and good radial outflow. Maximum sustained 
surface winds are estimated at 20 to 25 knots. Minimum sea level 
pressure is estimated to be near 1002 mb. The potential for the 
development of a significant tropical cyclone within the next 24 
hours remains medium.
      (2) the area of convection previously located near 14.5s 
65.4e, is now the subject of a tropical cyclone warning. See para. 
2.A.(1) for further details.
      (3) no other suspect areas.
3. Justification for reissue: upgraded area in para 2.B.(2) to 
warning status.//
