Australian region tropical cyclone seasons
1993–94, 1994–95, 1995–96, 1996–97, 1997–98

The 1995–96 Australian region cyclone season was an active Australian cyclone season, with Western Australia experiencing a record number of landfalling intense storms in the Pilbara region. The season produced a total of 19 tropical cyclones, of which 14 developed into named storms and 9 reached severe tropical cyclone status. The strongest of the season was Severe Tropical Cyclone Olivia, which also produced the highest recorded wind gust on record of 408 km/h (253 mph). Though several systems impacted land, the general sparsity of population centres in Australia limits the scale of damage. One person was confirmed to have been killed and cumulative losses were estimated at A$77 million (US$58.5 million).

Severe Tropical Cyclone Daryl–Agnielle

[edit]
Category 3 severe tropical cyclone (Australian scale)
Category 1 tropical cyclone (SSHWS)
 
Duration16 November – 19 November (Exited basin)
Peak intensity120 km/h (75 mph) (10-min);
965 hPa (mbar)

The first storm of the year and most intense across the Southern Hemisphere during the 1995–96 seasons, Cyclone Daryl was first identified several hundred kilometres west of Sumatra on 16 November. Initially tracking south-eastward, the system gradually attained gale-force winds as it neared the Cocos Islands late on 17 November. Squally conditions and heavy rain impacted the islands but no damage took place. Low wind shear allowed for further strengthening; a mid-level ridge south of the system forced Daryl to turn towards the west. Early on 19 November, the storm intensified into a severe tropical cyclone and attained winds of 130 km/h (80 mph) before crossing 90°E and entering the Mauritius area of responsibility. Upon crossing this border, Daryl was assigned a second name, Agnielle, by Mauritius. Over the following days, the system further deepened, peaking in strength as a Category 3 on the Australian intensity scale with 205 km/h (125 mph) and a barometric pressure of 915 hPa (mbar; 27.02 inHg). Steady weakening took place due to markedly stronger wind shear. Cyclone Daryl-Agnielle was last noted as a weak low pressure center on 25 November over the open waters of the southern Indian Ocean.[1]

Tropical Cyclone Emma

[edit]
Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
 
Duration2 December – 16 December
Peak intensity75 km/h (45 mph) (10-min);
990 hPa (mbar)

Emma stayed well off the Australian coast in the Indian Ocean. It spent most of its duration as a tropical low.

Severe Tropical Cyclone Frank

[edit]
Category 4 severe tropical cyclone (Australian scale)
Category 4 tropical cyclone (SSHWS)
 
Duration6 December – 13 December
Peak intensity175 km/h (110 mph) (10-min);
950 hPa (mbar)

It formed on 6 December 1995, and was the first cyclone to form in northwest coast of Australia during the 95/96 season. Cyclone Frank brought heavy winds and rains to the Pilbara coast. Frank was one of four cyclones to strike in that area.[2]

Severe Tropical Cyclone Gertie

[edit]
Category 3 severe tropical cyclone (Australian scale)
Category 1 tropical cyclone (SSHWS)
 
Duration17 December – 24 December
Peak intensity140 km/h (85 mph) (10-min);
965 hPa (mbar)

A tropical low formed in the Timor Sea on 16 December and tracked west-southwest as it deepened slowly. The low crossed into the WA region on 17 December and was named Gertie on the afternoon of the 18th. The cyclone then moved towards the south-southwest during the 19th but slowed to be almost stationary during the late afternoon and evening of that day. Gertie then began to move south, then southeastwards, crossing the coast near Mandora Station on 20 December. Gertie then passed to the northeast of Telfer producing near gale-force winds and heavy rain before dissipating on the 21st. The storm did only minor damage.[2]

Severe Tropical Cyclone Barry

[edit]
Category 4 severe tropical cyclone (Australian scale)
Category 1 tropical cyclone (SSHWS)
 
Duration4 January – 7 January
Peak intensity185 km/h (115 mph) (10-min);
950 hPa (mbar)

Barry formed in the Gulf of Carpentaria on 4 January, reaching a maximum intensity of Category 3 (Australian scale) before crossing the coast between Karumba and Kowanyama two days later. Heavy rains caused severe flooding across the southern Cape York Peninsula, however there were no deaths reported.

Severe Tropical Cyclone Hubert–Coryna

[edit]
Category 3 severe tropical cyclone (Australian scale)
Category 1 tropical cyclone (SSHWS)
 
Duration7 January – 9 January (Exited basin)
Peak intensity150 km/h (90 mph) (10-min);
955 hPa (mbar)

Hubert stayed well off the Australian coast in the Indian Ocean from 8 to 12 January 1996.[citation needed]

Severe Tropical Cyclone Celeste

[edit]
Category 3 severe tropical cyclone (Australian scale)
Category 1 tropical cyclone (SSHWS)
 
Duration26 January – 29 January
Peak intensity130 km/h (80 mph) (10-min);
965 hPa (mbar)

Celeste formed in the Coral Sea on 26 January 1996, and rapidly intensified into a Category 3 severe tropical cyclone (Australian scale), in part due to its position between equatorial and subtropical upper wind outflow channels. While intensifying it approached the northeastern Australian coast, with its centre coming within 24 km (15 mi) to the north of Bowen, Queensland on 27 January. After dumping heavy rain on the region, Celeste moved back out to sea. As it did, the cyclone passed to the north of the Whitsunday Islands while reaching peak intensity. Subsequently it quickly weakened.[3]

Tropical Cyclone Isobel

[edit]
Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
 
Duration27 January – 1 February
Peak intensity65 km/h (40 mph) (10-min);
995 hPa (mbar)

Isobel only lasted from 27 January 1996 to 1 February in the Timor Sea and did not pass close to any land.

Severe Tropical Cyclone Jacob

[edit]
Category 3 severe tropical cyclone (Australian scale)
Category 2 tropical cyclone (SSHWS)
 
Duration27 January – 8 February
Peak intensity155 km/h (100 mph) (10-min);
955 hPa (mbar)

TC Jacob formed on 1 February 1996 from a monsoonal low that moved across the Northern Territory and the Kimberley region of Western Australia before tracking over the Bonaparte Gulf. It closely followed the Western Australian coast and developed cyclone characteristics near Adele Island. Jacob continued to intensify and moved west-southwestwards, roughly parallel to the Pilbara coast. At peak intensity Jacob was a Category 3 storm with wind gusts near the centre estimated to be 200 kilometres per hour. The Kimberley and Pilbara coastal areas received heavy rains as the cyclone passed offshore. Only minor damage occurred and there were no deaths.[2]

Tropical Storm 12S

Storm names

[edit]

Tropical cyclones are assigned names by the Australian Bureau of Meteorology or Papua New Guinea. Tropical cyclones are named if they are non-frontal low pressure systems of synoptic scale developing over warm waters, or if Dvorak intensity analysis indicate the presence of gale force or stronger winds near the centre. Therefore, tropical systems with gales in one or more quadrants, but not near the centre, are not named.[18] All names assigned in the Australian region are selected sequentially. Only the names used during this cyclone season are listed below. The complete list of names for each basin are found in the World Meteorological Organization's official lists.[19]

Each Australian Tropical Cyclone Warning Centre (Perth, Darwin, and Brisbane) maintained a list of names arranged alphabetically and alternating male and female. Tropical cyclones that develop in the South-East Indian Ocean are assigned names by the Tropical Cyclone Warning Centre in Perth. This region includes the areas east of 90°E, south of the Equator, and west of 125°E. Tropical cyclones that develop south of the Equator between 125°E and 141°E are assigned names by the Tropical Cyclone Warning Centre in Darwin, Northern Territory. This area includes most of the cyclones that form in the Arafura Sea and Western Gulf of Carpentaria. Tropical cyclones in the Coral Sea and Eastern Gulf of Carpentaria between 141°E and 160°E and south of 10°S are assigned names by the Tropical Cyclone Warning Centre in Brisbane, Queensland.[19]

Storms that enter the region that were named by the Mauritius meteorological service or the Fiji Meteorological Service retain their original names. However, those that move from the Australian region into the South-West Indian Ocean (west of 90°E) are renamed by Météo-France. Additionally, the Tropical Cyclone Warning Centre in Port Moresby, Papua New Guinea reserves the right to name cyclones that develop in the Solomon Sea and Gulf of Papua, north of 10°S between 141°E and 160°E. Names issued by Port Moresby are retired after one use.[20]

Perth

  • Daryl - Emma - Frank - Gertie - Hubert - Isobel - Jacob - Kirsty

Darwin

  • Olivia

Brisbane

  • Barry - Celeste - Dennis - Ethel

Additionally, one storm, Jenna, was named by the Mauritius Meteorological Service.[21]

Retirement

[edit]

At the end of the season, the Bureau of Meteorology retired seven of the thirteen names used during the season. The names were Frank, Gertie, Kirsty, Barry, Celeste, Ethel and Olivia.[22][citation needed] The replacement names were Floyd, Glenda, Kara, Bruce, Cecily, Edna and Olwyn. Floyd and Glenda were used in 2006, Kara in 2007, Bruce and Edna in the 2013–14 season and Olwyn in 2015. Cecily was not retained after the naming lists were combined prior to the 2008-09 cyclone season.
