2000–01 Australian region cyclone season
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.
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, an approaching shortwave trough caused Sam to track southward the following day, towards the Australian coast. During its southward progression, Sam rapidly intensified, and reached its peak intensity on 7 December. The next day, the storm made landfall near Lagrange, Western Australia at the same intensity. Once inland, Sam was slow to weaken as it recurved eastward, and persisted for nearly a week inland before dissipating on 14 December.
Throughout its existence, Cyclone Sam brought heavy rainfall to a wide swath of northern Australia. 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. Most of the destruction wrought by Sam occurred near the coast, particularly in Bidyadanga and Anna Springs Station. Some buildings sustained considerable damage, and trees and power lines were felled, resulting in some power outages. Offshore, 163 illegal immigrants aboard two vessels were feared to have drowned, which would make Sam one of the deadliest cyclones in Australian history. However, these people were later accounted for.
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.
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. Vincent peaked with sustained winds of 100 km/h (65 mph) which made it a Category 2 tropical cyclone on the Australian tropical cyclone intensity scale. Cyclone Vincent crossed the Western Australia coast as a tropical low, a few kilometres south of Broome, Western Australia.
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.
