REMARKS:
Anika is now weakening under increasing N/NW shear after peaking earlier in the
day. Latest microwave imagery [11UTC SSMIS] now shows a clearly exposed LLCC
north of the convection.
Dvorak: DT=FT=2.5 based on shear pattern -0.5degree separation from deep
convection. CI held at 3.5 consistent with earlier ADT estimates.
Increasing shear associated with the influence of an upper level trough to the
south should continue the weakening process as Anika moves into cooler SSTs
south of 15S.
Forecast track is for continuing SE to ESE motion based on consensus of major
models excluding WBAR and TXLAPS.

The next bulletin for this system will be issued by: 20/1900 UTC by Perth TCWC.

REMARKS:
Anika has now weakened below tropical cyclone intensity under moderate to strong
N/NW shear and cooler SSTs. Latest imagery shows a clearly exposed LLCC
northwest of the convection.
Dvorak: FT=2.0 based on MET. CI of 2.5.
The LLCC is expected to track to the east southeast over the next 24 to 48
hours.

There will be no further bulletins for this system unless it reintensifies.
