REMARKS:
A tropical low, 16U, is moving away from the Australian mainland and struggling
to develop further in the northeast Coral Sea. 

The satellite signature of 16U remains only marginally organised. Reasonably
long lived bursts of convection continue to the north of the LLCC, but have so
far struggled to consolidate and wrap around the centre. 

Position is based on animated IR imagery and extrapolation from the ASCAT pass
at 1107UTC. Dvorak analysis is based on a curved band with approximately
0.45-0.5 wrap. DT is 2.5. MET is 3.0 based on a 24 hour D- trend, but PAT is
reduced to 2.5. Final T and CI 2.5. NESDIS ADT guidance is somewhat higher at
CI 3.1 / 47 knots (1 minute mean). Intensity held at 35 knots, with structure
(gales in northern quadrants only) likewise based on the 11UTC ASCAT pass.  

The environment is only marginally favourable and the system may struggle  to
intensify further in the short to medium term. The system continues to receive
moist low level monsoonal inflow, and lies in an area of diffluent upper level
flow north of an upper trough to the south. However, moderate ESE deep layer
wind shear coupled with dry air to the south may limit development. As a small
system, 16U will respond more rapidly to changes in environmental conditions.  

There is strong confidence in an ESE track under the influence of mid-level
steering and low level monsoonal flow.
