(KIMI) PUBLIC ADVISORY # FORCE THIRTEEN , ...... SUMMARY OF INFORMATION ----------------------------------- LOCATION...NEAR ... MAXIMUM SUSTAINED WINDS...MPH...KM/H MINIMUM CENTRAL PRESSURE...MB WATCHES AND WARNINGS ----------------------------------- NO WARNINGS IN EFFECT.
DISCUSSION ----------------------------------- Tropical cyclone Kimi has displayed a weakening trend over the past 6 to 12 hours, with deep convection becoming confined exclusively to the southern side of the centre and becoming more removed from the centre. The system has now been reclassified as a tropical low. Centre fix is based on animated IR imagery, surface observations and a 1522 UTC AMSR2 pass. Position is estimated as good. Dvorak DT based on shear pattern with centre within 0.25 deg of cold overcast giving DT 2.5. MET is 2.0 with PAT at 2.0. FT based on PT. Intensity is still set at 35 knots [10-min mean] with a small patch of gales persisting in the SW quadrant. The environment rapidly became less favourable over the past 6 to 12 hours, with vertical wind shear becoming west-northwesterly and increasing to about 20 knots associated with the approach of an upper level trough to the south of the system, and this is forecast to persist. Given its very small size, the system responded rapidly to this environmental change, with analysis indicating the mid to upper levels of the vortex have now weakened and decoupled from the low level circulation. With the recent structure changes and only a shallow vortex remaining, the system has become slow-moving well off the coast over the past 6 hours. Subsequent movement of a this shallower and weaker system is likely to be back towards the north-northwest due to low level ridging building along the central Queensland coast.
