The system has been difficult to locate for the past 6 hours. IR imagery shows
convection is still forming near the centre but there appears to be little real
curvature to the convection with a sharp edge along the convective blow up
indicating the system is still suffering under northerly shear.

Dvorak analysis leans heavily on MET/PAT with FT remaining at 2.0.  FInal
intensity estimate is 35 knots with gales restricted to southern quadrants.

The system is in a moist environment and over very warm SSTs. Upper divergence
is strong to the south but weak to non existant equatorward. Development has
thus far been constrained by wind shear. Shear may weaken a little during Friday
as the system moves around the western flank of an upper anticyclone before
experiencing increasing northwesterly winds aloft as an upper trough approaches.
There is decresing time for this system to develop before making landfall and
the forecast now peaks intensity at 45 knots. 

Deterministic [hi-res] model runs are in close agreement regarding track, which
is dominated by the anticyclone to the east and the approaching  mid-latitude
upper trough. There is greater divergence in track amongst ensemble members.

Models indicate the system remains coherent for some time and can be tracked
well into central parts of Australia.Copyright Commonwealth of Australia
