REMARKS:
EX-TROPICAL CYCLONE ZELIA IS DISSIPATING OVER THE INLAND PILBARA.

DEEP CONVECTION HAS BECOME COMPLETELY ABSENT FROM THE REMNANTS OF
EX-TROPICAL
CYCLONE ZELIA. CONFIDENCE IN THE ANALYSIS POSITION IS POOR. DUE TO
THE LACK OF
CONVECTION, THE CIRCULATION IS NOT EVIDENT ON PORT HEDLAND RADAR
DESPITE BEING
WITHIN RANGE. THE LOW-LEVEL CIRCULATION IS ALSO DIFFICULT TO LOCATE
ON IR
SATELLITE IMAGERY.

INTENSITY SET AT 30KN BASED ON SURFACE OBSERVATIONS AT MARBLE BAR AND
IRONBRIDGE AIRPORT.

AS ZELIA IS OVER LAND, DVORAK ANALYSIS AND OBJECTIVE AIDS ARE NO
LONGER VALID.
