2005-06 Australian region cyclone season
Encyclopedia
The 2005–06 Australian region cyclone season was an event in the ongoing cycle of tropical cyclone
formation. It began on 1 November 2005 and ended on 30 April 2006. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, which runs from 1 July 2005 to 30 June 2006.
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
.
persisted on 4 November about 560 km (345 mi) north of the Cocos Islands
, associated with a tight low-level circulation. With good outflow
and moderate but decreasing wind shear
, conditions favored development. By early on 5 November, the system consisted of a partially exposed circulation with deep convection on its western side, tracking southwestward. At 0400 UTC
that day, the Tropical Cyclone Warning Centre (TCWC) in Perth
issued a gale warning in association with the disturbance. Later in the day, the Joint Typhoon Warning Center
(JTWC) classified it as Tropical Cyclone 02S, and both the JTWC and TCWC Perth anticipated further strengthening.
Throughout its duration, TCWC Perth maintained the system as a 55 km/h (35 mph) tropical low. However, the JTWC assessed the storm as reaching peak winds of 85 km/h (50 mph), based on observations indicating the consolidation of convection over the center. The agency forecast the storm to strengthen further; however, by late on 6 November it had begun weakening. Around the same time, the storm crossed into the area of warning responsibility of Météo-France
in Réunion
(MFR); as such, it was re-designated as Tropical Depression 04. The depression continued southwestward as it slowly weakened. Early on 8 November, the JTWC issued its final warning, and six hours later, the MFR discontinued advisories while it was located about 1485 km (920 mi) southeast of Diego Garcia

island of Sumatra
. Early on 18 November, the TCWC Perth issued a gale warning on the system; at the time, the system consisted of cycling convection in association with several small circulations. The circulations organized into a well-defined center of circulation, and at 0000 UTC on 19 November it was classified as Tropical Cyclone Bertie about 835 km (515 mi) northwest of the Cocos Islands
. The storm tracked southwestward around the western periphery of a mid-level ridge
between Australia and Indonesia. Environmental conditions generally favored further strengthening, with good outflow
though moderate wind shear
, and late on 19 November the JTWC initiated advisories on Bertie.
Tropical Cyclone Bertie gradually strengthened and became a Severe Tropical Cyclone on 21 November. The next day, TCWC Perth issued its last advisory on the cyclone, as it was expected to cross 90ºE, which is dividing longitude line between TCWC Perth and the Météo-France (MFR) area of warning responsibility. However, Bertie turned due southward, and the MFR issued advisories for 30 hours as the cyclone remained just east of 90ºE, during which the MFR estimated Bertie attained peak winds of 185 km/h (115 mph). Early on 23 November, the JTWC assessed the cyclone as reaching winds of 210 km/h (135 mph), which equates to a marginal Category 4 on the Saffir-Simpson hurricane scale
. On 24 November, the cyclone crossed into the area of responsibility of the MFR, and it was renamed Intense Tropical Cyclone Alvin. Shortly thereafter the storm turned to a northwest drift, and encountering unfavorable conditions, Alvin rapidly weakened. The JTWC issued its last advisory on 26 November after it weakened to a tropical depression, and two days later the MFR discontinued advisories. The remnants of the storm continued northwestward until turning west-southwestward and dissipating on 3 December.
persisted over the system, preventing immediate development The low turned southwestward, and on 23 December it entered the area of responsibility of Météo-France
in Réunion
(MFR).
Upon entering the South-West Indian Ocean
, the MFR classified the system as Tropical Depression 06. Convection increased and organized, and the JTWC initiated advisories on Tropical Cyclone 04S on 24 December. However, wind shear increased shortly thereafter, resulting in weakening. On 25 December, the JTWC discontinued advisories, and a day later the MFR followed suit. The remnants tracked southwestward, and the MFR again issued advisories starting on 27 December. After passing near Rodrigues
, the system weakened again due to persistent vertical shear, and on 29 December the MFR again issued the final warning on the system.
and Dampier
next day, and dissipated on the 10th as it continued inland. On 12 December 2006, the Bureau of Meteorology announced that the name "Clare" would be retired, and will never be used for an Australian Cyclone ever again.
In preparation of the storm, 1,500 people were evacuated, while incoming flights and mining operations were closed. Although sustained wind speeds of 131 km/h and gusts of up to 142 km/h were recorded, the towns affected by TC Clare escaped with only minor structural damage. The precipitation associated with Ex-Tropical Cyclone Clare caused extensive flooding in the towns of Walkaway
and Lake Grace
over the weekend of 14–15 January. Because it made landfall at low tide, storm surge damage was negligible. Overall, damage was estimated to be at least A$5 million ($3.2 million USD), and Clare was responsible for no deaths.
Jim continued to intensify as it steadily tracked east-northeastward. Upper-level outflow associated with the storm gradually improved as the cyclone neared the edge of the Bureau of Meteorology's warning area. Shortly before crossing 160°E on 30 January, Jim intensified into a Category 3 cyclone, with winds reaching 120 km/h (75 mph 10-minute sustained). At the same time, the JTWC assessed the system to have become a Category 1 equivalent with winds of 120 km/h (75 mph 1-minute sustained). After crossing 160°E, warning responsibility of the cyclone was given to the RSMC in Nadi, Fiji. Upon entering their area of responsibility, Jim sharply turned southeast, attaining a peak intensity with winds of 150 km/h (90 mph 10-minute sustained) as it brushed New Caledonia
. By 1 February, the storm had transitioned into an extratropical cyclone
, dissipating a few days later.
As the storm was developing, torrential rainfall affected portions of coastal Queensland between 26 and 27 January. In a 24-hour span, 258 mm (10.2 in) of rain fell in Home Hill, leading to minor flooding. On 28 January, the cyclone brushed Flinders Reef
, Willis Island and Lihou Reef, bringing winds up to 65 km/h (40 mph) to all three areas.
Upon the formation of Kate, the Bureau of Meteorology warned vessels to avoid traveling near the storm due to rough seas and wind gusts up to 125 km/h (77.7 mph). Although the storm was deemed to have not been a threat to Queensland
, officials urged residents to ensure their disaster kits were ready and that preparations for a moderate storm, such as storing lose outdoor objects and clearing gutters, had been completed. Although the storm had no direct impact on land, large swells
produced by the system affected most of the Queensland coastline. In the Shire of Noosa, six surfers sustained serious injuries after wading into turbulent waters. Waves up to 1.8 m (5.9 ft) tossed the six surfers, leaving them with injuries ranging from broken noses and fractured ankles to head wounds from surfboards.
al storm. However, low wind shear
and well-developed outflow
gradually allowed convection
to develop near the center of circulation
. As the system near the Pilbara coastline of Western Australia
on 27 February, it intensified into a Category 1 cyclone and attained peak winds of 75 km/h (45 mph 10-minute sustained). The JTWC, however, reported the storm to have been slightly weaker, attaining peak winds of 65 km/h (40 mph 1-minute sustained). After moving inland near Mardie, Emma weakened to a tropical low but became exceedingly large, with the cloud cover from the storm encompassing most of Western Australia. The remnants of the weak storm persisted until 1 March, at which time it dissipated over the Great Australian Bight
.
Although a weak storm, rainfall from Emma caused flooding in numerous parts of Western Australia. In Karratha
, six people required rescue after their cars became stranded in flood waters. The most significant damage took place along the Murchison River
which swelled to roughly 16 km (9.9 mi) in width. Although only one town was threatened by the river, large areas of farmland were inundated by the expanding river, leading to substantial agricultural losses. Despite the extensive flooding, no fatalities were reported as a result of Emma.

Cyclone Larry is considered to be the worst cyclone to hit Queensland
since 1931. The total damage caused by Larry was estimated to be A$1 billion (2006).
's area of responsibility in late March. It later moved to the south-east where cyclone watches were issued for Lord Howe Island
and cyclone warnings for Norfolk Island
.
. The precursor disturbance drifted over Top End
and later across the northeastern portion of Western Australia, and after emerging into the Indian Ocean
it strengthened into a tropical storm. Aided by favourable environmental conditions, Glenda rapidly intensified to reach Category 5 status on the Australian cyclone scale
, and with a peak intensity of 910 mbar
it was among the strongest cyclones on record within the Australia region. On 30 March, it moved ashore near Onslow
as a Category 3 cyclone, and the next day it degenerated into a remnant tropical low over land.
The precursor disturbance produced heavy rainfall in the Kimberley region of Western Australia, causing record flooding and some road damage. Minor damage was reported at the final landfall of Glenda. Due to the sparse population and preparations made, the cyclone was not responsible for any deaths or injuries. In all, damages from the storm amounted to A$
1.2 million ($965,000 USD
). However, its name was later retired from the list of tropical cyclone names.

off the coast of Papua New Guinea
on 16 April. The storm quickly developed into a Category 1 cyclone the next day, at which time it was given the name Monica. Traveling towards the west, the storm intensified into a severe tropical cyclone before making landfall in Far North Queensland
, near the Lockhart River, on 19 April. After moving over land, convection
associated with the storm quickly became disorganized.
On 20 April, moved over the Gulf of Carpentaria
and began to re-intensify. Over the following few days, deep convection formed around a 37 km (23 mi) wide eye
. Early on 22 April, the Bureau of Meteorology assessed Monica to have attained Category 5 status, on the Australian cyclone intensity scale. The JTWC also upgraded Monica to a Category 5 equivalent cyclone, on the Saffir–Simpson Hurricane Scale. The storm attained its peak intensity the following day with winds of 250 km/h (155 km/h 10-minute sustained) and a barometric pressure of 916 hPa (mbar). At the same time, the JTWC assessed the storm to have attained winds of 285 km/h (180 mph 1-minute sustained), ranking it as one of the strongest storms ever recorded in the Southern Hemisphere. On 24 April, Monica made landfall about 35 km (21.7 mi) west of Maningrida
, at the same intensity. Rapid weakening took place as the storm moved over land. Less than 24-hours after landfall, the storm had weakened to a tropical low. The remnants of the former-Category 5 cyclone persisted until 28 April over northern Australia.
In contrast to the extreme intensity of the cyclone, relatively little structural damage resulted from it. No injuries were reported throughout the storm's existence and losses were estimated to be A$
1.6 million ($766,000 USD). However, severe environmental losses took place. In the Northern Territory, about 7,000 km2 (4,349 mi2) of trees were downed by Monica's high wind gusts. In response to the large loss of forested area, it was stated that it would take several hundred years for the area to re-flourish.

intensity analysis indicate the presence of gale force
or stronger winds near the centre. Therefore, a tropical system with gales in one or more quadrants, but not near the centre, are not named.

Severe Tropical Cyclone Clare
A tropical low formed north of Northern Territory and tracked roughly parallel to the coast. On 7 January, TCWC Perth started issuing tropical cyclone advisories on this system. The low became Tropical Cyclone Clare when it was located 250 km north of Cape Leveque or 430 km north of Broome. A steady strengthening trend continued and Clare peaked as a 139 km/h (75 kt) storm, or a Category 3 cyclone on the Australian scale, with a minimum pressure of 960 hPa at the centre of the system. On 9 January the cyclone made landfall near KarrathaKarratha, Western Australia

Tropical Cyclone Daryl
On 17 January, TCWC Perth started issuing tropical cyclone advices for a tropical low overland. The low tracked into Kuri Bay next day and developed into Tropical Cyclone Daryl. It continued to strengthen, and on 21 January briefly became a Severe Tropical Cyclone operationally but was downgraded to a 55kt Tropical Cyclone following the end of season analysis. Over the next two days, Daryl tracked parallel to the West Australian coast, mostly as a Category 2 system. Daryl continued tracking in a south-westerly direction before being downgraded to a low-pressure system on 23 January. The cyclone did not cross the coast.Northern Territory Monsoon Low
A tropical low developed off the north coast of the Top End in late January. It made landfall in the Darwin area and drifted down the western border of the Northern Territory. The low brought heavy falls to many parts of the western Northern Territory. The low continued to move south through the Victoria River District and into the Tanami Desert. The Victoria Highway was cut by floodwaters, isolating Timber Creek and the Victoria River Crossing. On 31 January, the low deepened producing near gale force winds.- Significant Weather Summaries from Australian Bureau of Meteorology

Severe Tropical Cyclone Jim
On 24 January, a broad area of low pressure developed near the coast of Queensland after a monsoonal trough passed through the region. Northeasterly winds flowing into the system quickly increased convection, resulting in heavy rainfall over coastal regions of Queensland. The slow movement of the developing low continued through 26 January before turning northeast in response to a mid-level ridge to the north. On 28 January, the JTWC began monitoring the system as Tropical Storm 10P and shortly after, the Bureau of Meteorology classified the storm as a Category 1 cyclone and gave it the name Jim.Jim continued to intensify as it steadily tracked east-northeastward. Upper-level outflow associated with the storm gradually improved as the cyclone neared the edge of the Bureau of Meteorology's warning area. Shortly before crossing 160°E on 30 January, Jim intensified into a Category 3 cyclone, with winds reaching 120 km/h (75 mph 10-minute sustained). At the same time, the JTWC assessed the system to have become a Category 1 equivalent with winds of 120 km/h (75 mph 1-minute sustained). After crossing 160°E, warning responsibility of the cyclone was given to the RSMC in Nadi, Fiji. Upon entering their area of responsibility, Jim sharply turned southeast, attaining a peak intensity with winds of 150 km/h (90 mph 10-minute sustained) as it brushed New Caledonia

Northern Territory Tropical Low
A tropical low formed in the Arafura Sea north of Nhulunbuy on 24 February. It moved northwest into the Banda Sea and deepened during the next two days. Through the remainder of February it moved slowly southsouthwest into the Timor Sea. The low persisted into March but did not reach cyclone intensity. A cyclone watch was issued for a portion of Western Australia though the maximum sustained winds of the low were just 25 knots.- Significant Weather Summaries from Australian Bureau of Meteorology
