2003–04 Australian region cyclone season

The storm lost its tropical character as it crossed the Cape York Peninsula and entered the Gulf of Carpentaria on 11 February.

The remnant travelled over Northern Territory and Western Australia, before merging with a cold front to the south of Perth.

[6] A low-pressure system formed in the Gulf of Carpentaria and moved westward into the Timor Sea; it was named Tropical Cyclone Fay on 16 March.

On 21 March, Cyclone Fay intensified even further as the storm approached Scott Reef where significant damage occurred.

Looping back towards the Kimberley coast, Fay – now a Category 3 system – approached to within 90 km of Broome on 25 March, before turning to the south-west.

Fay crossed the Pilbara coast between the pastoral stations of Pardoo and Wallal between 8 am and 9 am WST on 27 March as a Category 4 storm with estimated maximum wind gusts of around 235 km/h near the center.

Little wind damage was reported from the storm despite its intensity as it made landfall in a remote part of the WA coast and consequently only impacted sparsely populated pastoral and mining areas.

As the system passed close to the Yarrie mine its translation speed reduced and some 200 workers were locked down for 8 hours in two squash courts as accommodation units were overturned, water tanks "shredded" and power lines cut.

A multi-centred tropical low formed adjacent to the north Queensland tropical coast near Cooktown as early as 20 March within a very active monsoon trough that stretched across the northern Coral Sea and Cape York Peninsula toward New Caledonia, and initially had a subtropical appearance.

Thereafter, Grace began to undergo extratropical transition with an increasingly asymmetric wind field due to a squeeze with a surface ridge to the south.

Grace rapidly lost its entire upper-level structure and was downgraded at 23/1800 UTC from tropical cyclone status when located approximately 400 nautical miles (740 km) east-northeast of Sandy Cape (23.6S/162.3E).

The remnant surface wind field of the system meandered to the east and then to the east-northeast over the following days, producing a very broad area of gales to its south through the Tasman Sea.

A large section of one lane of the Captain Cook Highway north of Cairns collapsed after a landslide consisting of nearly 20 metres of rock and boulders the size of cars destroyed the ocean-side road.

Officials in the French Pacific territory put up barriers around the island of Amedee, which was threatened by a toxic oil slick, estimated to cover an area of 20 square kilometres.

[6] During 20 December, Tropical Disturbance 02F was last noted by the FMS, as it moved into the region from the South Pacific basin about 665 km (415 mi) to the northwest of Honiara in the Solomon Islands.

[9] The system subsequently moved south-eastwards and remained poorly organised, before it was last noted by the FMS later that day while it was located to the south of San Cristobal Island.
