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 As Zelia is over land, Dvorak analysis and objective aids are no longer valid.
