REMARKS:
Tropical low 21U has improved markedly in the last 24 hours and is expected to
develop into a tropical cyclone in the next 12-24 hours. 

The low was located using visible imagery and several good microwave passes and
there is moderate confidence in the position. Recent imagery shows improved
curved banding and the DT has increased from 1.0 yesterday to 2.5 today. FT is
constrained to 2.0 and CI is set at 2.0. Intensity is estimated at 30 knots.
There is no objective guidance available as yet. 

Model guidance is reasonably consistent both in development and movement. 

The low expected to intensify further over the next 24 hours in a favourable
environment. It is currently located under a shear ridge in a moist
environment. A mid-level trough located to the south is providing good upper
divergence and good outflow channels to the south. During Friday the
environment will become unfavourable and 21U is expected to weaken below
tropical cyclone strength as dry air becomes entrained into the core and the
upper circulation becomes removed. The low is expected to persist from most of
next week moving west over the Indian Ocean. 

21U is currently being steered to the southeast by the mid-level trough located
to the south of the system and this steering regime is expected to persist
through Thursday. During Friday the trough will assist in removing the upper
circulation and the steering influence is likely to be lower down in the
atmosphere. Guidance suggests 21U will move back to the west under the
influence of the 700 hPa ridge.
