Systems

Severe Tropical Cyclone Alex

Basin:Aus
Track:Alex 1981 track.png
Formed:October 18
Dissipated:October 27
10-Min Winds:80
1-Min Winds:85
Pressure:964

See also: List of off-season Australian region tropical cyclones. A tropical low developed from an active convergence zone on 18 October. The system intensified into a tropical cyclone the next day and received the name Alex. Alex moved southeast and steadily intensified, reaching its peak intensity with 10-minute sustained winds of 150abbr=onNaNabbr=on and a barometric pressure of 964 hPa (28.47 inHg) on 21 October. Alex weakened as strong wind shear caused the convection and circulation to separate, dissipating on 27 October.[1]

Tropical Cyclone Amelia

Basin:Aus
Track:Amelia 1981 track.png
Formed:November 30
Dissipated:December 7
10-Min Winds:35
1-Min Winds:45
Pressure:996

A tropical low was identified in the southern Gulf of Carpentaria on 1 December, moving steadily northwest. It soon moved over land, re-emerging off the Northern Territory coast on 3 December. Late on 4 December, the low reached tropical cyclone status, receiving the name Amelia as it moved west-southwest through the Timor Sea. Soon afterwards, however, the system fell below cyclone intensity. It drifted west-southwest over the next few days, dissipating on 8 December.[2]

Tropical Cyclone 04U

Basin:Aus
Track:Unnamed BoM TC 1981 track.png
Formed:December 20
Dissipated:December 22
10-Min Winds:45
Pressure:988

A tropical low formed in a weak monsoon trough over the Gulf of Carpentaria early on 20 December. It moved westward and intensified, becoming a cyclone later that day, although it did not receive a name. At 1400 UTC on 20 December, it made landfall near Gove at its peak intensity with winds of 85abbr=onNaNabbr=on and a minimum pressure of 990 hPa. The strongest winds were likely in the southern quadrants due to its rapid westward movement. The cyclone weakened as it moved over land, but emerged offshore near Darwin on the 21st. Now over water, it once again intensified to tropical cyclone intensity, reaching a secondary peak intensity with winds of 75abbr=onNaNabbr=on and a pressure of 992 hPa. The system dissipated on 23 December.

At Gove, sustained winds of 115 km/h and gusts of over 148 km/h were recorded, the highest from the system. Extensive tree damage occurred in the Gove area, and some minor damage to ships occurred at the Nabalco Wharf.[3]

Severe Tropical Cyclone Chris–Damia

Basin:Aus
Track:Chris-Damia 1982 track.png
Formed:January 5
Dissipated:January 11 (Exited basin)
10-Min Winds:105
1-Min Winds:115
Pressure:934

Chris-Damia was the most intense storm of the season. Its precursor formed to the northwest of Christmas Island on 5 January, drifting slowly southwards. The system reached cycle intensity at 00:00 UTC on 7 January, receiving the name Chris. Over the next few days, Chris moved generally westwards as it steadily deepened, steered by a strong anticyclone located south of the storm. An eye became visible on satellite imagery during 9 January, and Chris reached its peak intensity with 10-minute sustained winds of 195abbr=onNaNabbr=on and an estimated central pressure of 934 hPa during the 11th, moving into the South-West Indian Ocean later that day.[4] Chris-Damia became the strongest storm on record in the South-West Indian Ocean at the time, with an estimated pressure of 898 hPa (mbar).[5]

Tropical Cyclone Bruno

Basin:Aus
Track:Bruno 1982 track.png
Formed:January 11
Dissipated:January 22
10-Min Winds:50
1-Min Winds:65
Pressure:980

On 10 January, a weak tropical low formed in the Gulf of Carpentaria from a monsoon trough. The low drifted slowly westwards, crossing the coast near Maningrida late on the 14th. Despite moving over land, the system continued to organise and reached cyclone intensity at 18:00 UTC on 15 January, while the centre was located near Wadeye. The storm, now named Bruno, continued to develop over the Joseph Bonaparte Gulf and reached an initial peak intensity with winds of 90abbr=onNaNabbr=on and an estimated central pressure of 989 hPa (mbar) late on the 15th. Bruno made another landfall again at about 07:00 UTC on 16 January, turning towards the southwest and steadily weakening, although it continued to produce gale-force winds as it moved through the West Kimberley. After Bruno passed Port Hedland, the system moved out to sea and rapidly reintensified. Bruno reached its ultimate peak intensity at 15:00 UTC on 19 January, with winds of 90abbr=onNaNabbr=on and an estimated central pressure of 980 hPa (mbar). The storm once again made landfall in the Exmouth Gulf later that day. A weakened Bruno moved out to sea again the next day but the system made its final landfall south of Perth on January 22 and dissipated soon after.

Bruno caused torrential rainfall to many areas of Western Australia, especially in the southwest where some stations set records for January rainfall. Severe flooding occurred in the southwest, with the Blackwood River reaching its highest level in over 25 years. Many bridges were washed away and there was extensive road and rail damage. A number of towns were flooded, with 75 houses being flooded in Nannup. Total damage was estimated at $10 million (1982 AUD, $10.9 million 1982 USD).[6]

Tropical Cyclone Daphne–Fifi

Basin:Aus
Track:Daphne-Fifi 1982 track.png
Formed:January 11
Dissipated:January 21
10-Min Winds:50
1-Min Winds:50
Pressure:986

Operationally considered two separate cyclones, Daphne-Fifi developed from the same monsoon trough that also spawned Cyclones Bruno and Errol. The system was first identified on 11 January. It drifted southeast and became a tropical cyclone at 09:00 UTC the next day. Daphne-Fifi slowly intensified as it moved towards the Cocos (Keeling) Islands. Curving towards the east, Daphne-Fifi reached its peak intensity early on 16 January with peak winds of 95abbr=onNaNabbr=on and an estimated central pressure of 986 hPa (mbar). On the 19th, the system accelerated towards the southeast and weakened, dissipating a few days later as it crossed the Western Australian coast. The storm caused no damage or effects to land apart from disruption to shipping operations at Christmas Island.[7]

Tropical Cyclone Errol

Basin:Aus
Track:Errol 1982 track.png
Formed:January 11
Dissipated:January 18
10-Min Winds:55
1-Min Winds:50
Pressure:980

Errol first became a tropical low on 11 January. After developing, the system moved in a general southwest to west direction, becoming a tropical cyclone at 00:00 UTC on the 13th. Errol slowly intensified over the coming days, reaching its peak intensity on 15 January with winds of 100abbr=onNaNabbr=on and an estimated central pressure of 980 hPa (mbar) as it recurved towards the southeast. After peaking, the storm weakened and Errol merged with Cyclone Bruno on the 18 January.[8] The storm caused flood damage in Western Australia.[9]

Tropical Cyclone Abigail

Basin:SPac
Track:Abigail 1982 track.png
Formed:January 22
Dissipated:February 1 (Exited basin)
10-Min Winds:60
1-Min Winds:65
Pressure:979

The first cyclone of the season to affect Queensland, Abigail originated from a low that developed off of the South East Queensland coast on 22 January. For the next 3 days, the low moved northeast, and then northwest, slowly intensifying. On 25 January, the low turned towards the southeast, becoming a cyclone the following night. During the next 3 days, Abigail executed a cyclonic loop, and it made another major turn towards the east-northeast on the 30th. Abigail reached its highest intensity in the Australian region on 1 February with winds of 120abbr=onNaNabbr=on and an estimated central pressure of 975 hPa (mbar), moving out of the basin immediately after. Abigail caused no damage or fatalities in the Australian region.[10]

Tropical Cyclone Graham

Basin:Aus
Track:Graham 1982 track.png
Formed:January 26
Dissipated:February 2
10-Min Winds:55
1-Min Winds:60
Pressure:980

A low formed just south of the Intertropical Convergence Zone on January 27. Moving eastward, it reached cyclone status before it made landfall in the Kimberley Region the next day. Weakening to a tropical low, it recurved to the west on the 29th, steered by a developing ridge of high pressure. Early on January 31, the low moved out to sea and quickly redeveloped before once again turning to the southwest and nearing the coast. Just before it made its second landfall near Port Hedland, Graham peaked with winds of 100abbr=onNaNabbr=on and a minimum central pressure of 980 hPa (mbar). During the January 28–30 period, Graham caused extensive landfall over the Kimberley, with 178 mm recorded in Broome during a 24-hour period ending at 01:00 UTC on the 30th. After its second landfall, building and tree damage was reported at Pardoo Station.
