REMARKS:
Dvorak at 0900 UTC. Using shear pattern, low level centre was about 1.25 degrees
from edge of cloud on visible imagery. DT was 2.0. Could also get 0.2 to 0.3
curved band wrap. 

At 1200 UTC. Curved band wrap of 0.3 gives a DT of 2.0. Trend was D with MET/PAT
of 2.0. FT/CI was 2.0. Cocos Island Airport at 1200 UTC reported mean winds of
24 knots [10 minute average]. Intensity set to 30 knots.

At 1800 UTC. Curved band wrap of 0.3/0.4 gives a DT of 2.0 to 2.5. Trend was D
with MET/PAT of 2.0. FT/CI was 2.0. Cocos Island Airport at 1800 UTC reported
mean winds of 21 knots [10 minute average]. Intensity set to 30 knots

09U has continued a general southwest track, being steered by a mid level ridge
to the southeast. Model guidance is in good agreement with a continued southwest
track over the next 24 to 48 hours. 

There is a good upper divergence with good poleward outflow. CIMMS shear at 09
UTC showed strong easterly shear between 30 and 40 knots.

As the system moves towards the southwest conditions become more favourable for
development with the shear decreasing. Gales may develop to the south of the
system before it reaches tropical cyclone intensity during Saturday. Fresh to
strong winds are currently being observed at Cocos Island Airport. The risk of
gales on the Cocos [Keeling] Islands continues until Saturday afternoon or
evening. After this time the system is likely to intensify further but be moving
far enough away from the islands.

Based on the current track, the system will move into La Reunion's area of
responsibility between 1200 and 1800 UTC 14 February.
