REMARKS:
TROPICAL CYCLONE MITCHELL HAS MOVED OVER LAND AND WEAKENED INTO A
TROPICAL LOW.


MITCHELL WEAKENED INTO A TROPICAL LOW AS IT CROSSED THE GASCOYNE
COAST, EAST OF
SHARK BAY, AT 1700 UTC. THE RADAR SIGNATURES ON CARNARVON RADAR HAVE
DETERIORATED. THE CENTRE HAS BECOME MORE DIFFUSE AND IS LOCATED WITH
LOW
CONFIDENCE.

INTENSITY: 35 KN IN NORTHERN QUADRANTS.  WHILE PERIPHERAL
OBSERVATIONS ARE NO
LONGER REPORTING ANY GALES, THERE ARE LIMITED OBSERVATIONS SO
INTENSITY IS
BASED ON QUADRANT GALES PERSISTING IN GUIDANCE.

DVORAK ANALYSIS: NIL AS THE SYSTEM IS OVER LAND.

MITCHELL IS CONTINUING TO SHOW SIGNS OF WEAKENING ON SATELLITE
IMAGERY WITH
CONVECTION WELL SHEARED TO THE SOUTH. SHEAR HAS INCREASED TO 25-30 KN
AT 1500
UTC. DAMAGING WIND GUSTS MAY PERSIST IN THE NORTHERN QUADRANTS DURING
EARLY
TUESDAY MORNING AS IT CONTINUES TO WEAKEN OVER LAND. THE REMNANTS OF
MITCHELL
SHOULD MOVE SOUTHEAST ON TUESDAY BEFORE DISSIPATING OVER INLAND
WESTERN
AUSTRALIA.
