The 2003–04 Australian region cyclone season was a slightly below average tropical cyclone season. It began on 1 November 2003 and ended on 30 April 2004. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, which runs from 1 July 2003 to 30 June 2004.
Tropical cyclones in this area are monitored by four Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology in Perth, Darwin, and Brisbane; and TCWC Port Moresby in Papua New Guinea.
Systems
Severe Tropical Cyclone Jana
Formed on 6 December and dissipated on 12 December.
Severe Tropical Cyclone Debbie
Formed on 16 December and dissipated on 23 December. Crossed the Northern Territory coast as a Category 1.
Tropical Low Ken
Formed on 1 January 2004 and dissipated on 6 January. Operationally monitored Ken to have reached tropical cyclone intensity for 24 hours, but post-analysis revealed that Ken never was a tropical cyclone.
Monsoon Depression
Existed between 10 and 17 January. Caused heavy rainfall across western Queensland and New South Wales.
Tropical Cyclone Linda
Formed on 28 January and dissipated on 1 February.
Tropical Cyclone Fritz
A tropical low developed on 10 February in the northern Coral Sea, within an active monsoon trough. The system developed rapidly and becoming Tropical Cyclone Fritz when it was northeast of Cooktown. Fritz moved rapidly to the west, and made landfall on the northern Queensland coast with winds of 75 km/h. The storm lost its tropical character as it crossed the Cape York Peninsula and entered the Gulf of Carpentaria on 11 February. The low reintensified over the favourable conditions in the Gulf, and reached its peak with 95 km/h winds near Mornington Island. Radar imagery showed evidence of an eye as the storm passed over the island on 12 February. It then crossed over the coast onto mainland Australian and degenerated overland. The remnant travelled over Northern Territory and Western Australia, before merging with a cold front to the south of Perth.
Cyclone Fritz brought up to 309 mm of rain to the Cairns area. This led to a number of landslides, one of which caused severe property damage in Yorkeys Knob. There was flash flooding near Innisfail when 74 mm of rain fell in one hour. Fritz uprooted a number of trees on Mornington Island, but there was no other damage there. There were no casualties from the storm.
Severe Tropical Cyclone Monty
Cyclone Monty was a small cyclone that formed off the Kimberley coast around 27 February 2004. Monty then strengthened into a Category 4 cyclone as it moved parallel with the Pilbara coast. The cyclone made landfall near Mardie Station as a Category 3 cyclone on 1 March. Monty damaged several boats and caused isolated flooding.
Tropical Cyclone Evan
Formed on 27 February and dissipated on 4 March. Crossed Groote Eylandt and the Northern Territory mainland, causing flooding.
Subtropical Storm
A subtropical cyclone formed on 2 March and crossed the coast in southeast Queensland on 5 March, bringing heavy rain and strong winds. A storm surge caused inundation along the coasts.
Tropical Cyclone Nicky–Helma
Formed on 8 March, moved west of the region on 10 March, and was renamed Helma.
Severe Tropical Cyclone Fay
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. Fay was 400 km north of Wyndham and 330 kilometres west northwest of Darwin. There were reports along the Kimberley Coast of gale-force winds. 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. Broome experienced strong winds with gale-force gusts, some heavy rain and heavy seas but escaped serious damage.
Fay then headed further away from the coast on the 25th before resuming a general southerly track on the 26th. 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.
