REMARKS:
EX-TROPICAL CYCLONE LUANA HAS WEAKENED TO A TROPICAL LOW. WHILE THE
SYSTEM
STILL SHOWS A REASONABLE SATELLITE SIGNATURE AND DEEP CONVECTION IS
PERSISTING
AROUND THE SYSTEM OVER LAND, THE RADAR SIGNATURE HAS DETERIORATED AND
THE
CENTRE BECOME MORE DIFFUSE. PERIPHERAL OBSERVATIONS ARE NO LONGER
REPORTING ANY
GALES.

CENTRE POSITION BASED ON BROOME RADAR WITH MODERATE CONFIDENCE.
INTENSITY
ESTIMATED AT 30 KNOTS BASED ON PERIPHERAL OBSERVATIONS AND NWP.

THE REMNANT TROPICAL LOW WILL BE STEERED SOUTH THROUGH THE INTERIOR
OF WESTERN
AUSTRALIA AROUND THE PERIPHERY OF A MID-LEVEL RIDGE TO THE EAST. THE
BROADER
ENVIRONMENT REMAINS FAVOURABLE IN THE SHORT TERM, WITH LOW SHEAR
PERSISTING
ALONG TRACK AS AN UPPER TROUGH TO THE SOUTH RELAXES. EX-LUANA IS
LIKELY TO
REMAIN A COHERENT SYSTEM OVER LAND FOR SEVERAL DAYS.
