The 2000–01 Australian region cyclone season was a below average tropical cyclone season. It began on 1 November 2000 and ended on 30 April 2001. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, which runs from 1 July 2000 to 30 June 2001.

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.[1]


Severe Tropical Cyclone Sam[edit]

Category 4 severe tropical cyclone (Australian scale)
Category 3 tropical cyclone (SSHWS)
Sam Dec 8 2000 0210Z.jpg Sam 2000 track.png
Duration 3 December – 10 December
Peak intensity 180 km/h (110 mph) (10-min)  935 hPa (mbar)

Sam originated from a tropical low that formed in the Arafura Sea on 28 November. Tracking generally westward, the initial low-pressure area remained generally weak until it entered the Timor Sea, by which time it had strengthened into a tropical cyclone on 5 December. Though a subtropical ridge was forcing the cyclone westward at the time,[2] an approaching shortwave trough caused Sam to track southward the following day, towards the Australian coast.[3][4] During its southward progression, Sam rapidly intensified, and reached its peak intensity on 7 December.[2][3][4] The next day, the storm made landfall near Lagrange, Western Australia at the same intensity.[5] Once inland, Sam was slow to weaken as it recurved eastward, and persisted for nearly a week inland before dissipating on 14 December.[4]

Throughout its existence, Cyclone Sam brought heavy rainfall to a wide swath of northern Australia.[3][4] Rainfall peaked at520 mm (20 in) in Shelamar over a 48-hour period ending on 11 December. Upon making landfall, damage was considerable, albeit localized.[4] Most of the destruction wrought by Sam occurred near the coast, particularly in Bidyadanga and Anna Springs Station.[3][4][6] Some buildings sustained considerable damage, and trees and power lines were felled, resulting in some power outages.[2] Offshore, 163 illegal immigrants aboard two vessels were feared to have drowned, which would make Sam one of the deadliest cyclones in Australian history.[2][7] However, these people were later accounted for.[8]

Tropical Cyclone Terri[edit]

Category 2 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
Terri jan 30 2001 0541Z.jpg Terri 2001 track.png
Duration 27 January – 31 January
Peak intensity 110 km/h (70 mph) (10-min)  975 hPa (mbar)

Terri formed on 27 January 2001 near the northern Kimberley coast. The storm paralleled the coast, reaching Category 2 strength before making landfall near Pardoo early on 31 January. The storm dissipated Late on the same day.[9]

Tropical Cyclone Winsome[edit]

Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
Winsome Feb 11 2001 0518Z.png Winsome 2001 track.png
Duration 8 February – 14 February
Peak intensity 75 km/h (45 mph) (10-min)  981 hPa (mbar)

Winsome was a weak system that developed from a low in the Gulf of Carpentaria on 8 February.

Torrential rains produced by the storm in the Northern Territory resulted in severe flooding which killed two people.[10]

Tropical Cyclone Vincent[edit]

Category 2 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
Vincent Feb 12 2001 0650Z.png Vincent 2001 track.png
Duration 7 February – 15 February
Peak intensity 100 km/h (65 mph) (10-min)  980 hPa (mbar)

Cyclone Vincent formed on 7 February 2001, 900 km northwest of Onslow, Western Australia from an active monsoonal trough. Wind shear prevented the tropical low from intensifying for a few days, but once the storm formed it began to move southeast and intensify. Soon it intensified into a Category 2 cyclone. Wind shear soon became stronger and Cyclone Vincent weakened to a Category 1 cyclone. Cyclone Vincent crossed the Western Australia coast as a tropical low, a few km south of Broome, Western Australia.

Tropical Cyclone Wylva[edit]

Category 1 tropical cyclone (Australian scale)
Wylva Feb 16 2001 0426Z.png Wylva 2001 track.png
Duration 14 February – 22 February
Peak intensity 75 km/h (45 mph) (10-min)  990 hPa (mbar)

Wylva formed from a low in the Gulf of Carpentaria on 15 February. Wylva briefly became a Category 1 tropical cyclone before making landfall near Booroloola in the morning of 16 February. Even though the system made landfall in a remote area, the remnants of the system caused $13 million in damage and around 700 people had to be evacuated. The remnants of Wylva dissipated on 22 February near Nanutarra.

Tropical Low 10P (07F)[edit]

Tropical low (Australian scale)
Tropical storm (SSHWS)
10-P Feb 17 2001 1949Z.png 10-P 2001 track.png
Duration 16 February – 16 February (exited basin)
Peak intensity 55 km/h (35 mph) (10-min)  1000 hPa (mbar)

This storm moved from Brisbane's area of responsibility into Fiji's on 16 February. It dissipated on the 18th.

Severe Tropical Cyclone Abigail[edit]

Category 3 severe tropical cyclone (Australian scale)
Tropical storm (SSHWS)
Abigail Feb 27 2001 1115Z.jpg Abigail 2001 track.png
Duration 24 February – 8 March
Peak intensity 120 km/h (75 mph) (10-min)  970 hPa (mbar)

On 24 February 2001, Cyclone Abigail formed about 80 km northeast of Cairns, Australia. It then made landfall in Queensland as a Category 1 storm.

Severe Tropical Cyclone Walter[edit]

Category 4 severe tropical cyclone (Australian scale)
Category 2 tropical cyclone (SSHWS)
Temporary cyclone south.svg Walter 2001 track.png
Duration 1 April – 8 April
Peak intensity 170 km/h (105 mph) (10-min)  940 hPa (mbar)

Walter was a storm that formed east of Christmas Island and tracked westward at a low latitude.

On 3 April, Cocos Island was placed under a cyclone watch as Walter approached the island.[11] Throughout 5 April, heavy rains and high winds, estimated up to 90 km/h (56 mph) battered the area as Walter bypassed the island.[12]

Tropical Cyclone Alistair[edit]

Category 2 tropical cyclone (Australian scale)
Category 1 tropical cyclone (SSHWS)
Alistair apr 18 2001 0539Z.jpg Alistair 2001 track.png
Duration 15 April – 23 April
Peak intensity 110 km/h (70 mph) (10-min)  975 hPa (mbar)

The second most damaging cyclone of the 2000–01 cyclone season, Alistair made landfall close to Carnarvon on 24 April 2001 as a poorly organized cyclone. The centre passed just to the north of town with a wind gust to 67 kilometres per hour from the northeast recorded at 4:11 am. Minimum pressure of 1002.9 hPa was recorded at 5 am, followed by the peak recorded wind gust of 90 kilometres per hour from the southeast at 6 am. A total of 24 mm of rainfall was reported in Carnarvon. Plantations to the north of Carnarvon reported 30-40% crop losses, with wind estimates of 100 to 110 kilometres per hour.[13]
