Tropical Cyclone 01S
On 25 October, RSMC La Reunion reported that a tropical disturbance has formed in the South Western Indian Ocean, and gave it the identifier "01". On the same day, the Joint Typhoon Warning Center (JTWC) identified the tropical disturbance as a low pressure area, located at approximately 800 nmi east of Diego Garcia. On 26 October, the MFR upgraded the disturbance into a tropical depression. Later that day, the JTWC upgraded the low pressure area directly into a tropical storm. On 27 October, the MFR reported that the system slightly weakened. Later that day, the MFR reported that the system further weakened into a Tropical Disturbance. Late on the same day, the JTWC has also reported that the storm weakened into a lower end Tropical Depression issuing their final warning on the system. Despite its weakness, the system had very good convection and showed a few signs of re-intensifying. However, on 29 October, the convection in the system started depleting and the disturbance continued to weaken. Later, the MFR issued their final advisory on the disturbance. The remnants of the system persisted as they slowly moved west, until it dissipated completely on 1 November, just south of the Arabian Sea.

Tropical Cyclone Abele (03S)
On 29 November, both the TCWC Perth and the Météo-France (MFR) reported that a tropical distrubance had formed within the South-West Indian Ocean, and gave it the identifier "02". Later that day, the Joint Typhoon Warning Center (JTWC) classified it as Tropical Cyclone 03S, locating it 700 nmi west of Cocos Island. On 30 November, the MFR upgraded the disturbance into a tropical depression. On 1 December it was named Abele by the Mauritius Meteorological Service as it became the first tropical storm of the season. On the very same day, the MFR reported that Abele intensified into a severe tropical storm. On 2 December, the MFR reported that Abele continued to intensify and became a tropical cyclone. It was given a Category 1 Tropical cyclone status by the JTWC. On 3 December, both the JTWC and MFR reported that Abele crossed 90°E and moved into the Australian region.

Tropical Cyclone Bingiza (13S)
Early on 9 February, the Météo-France (MFR) upgraded an area of low pressure into a Tropical Disturbance and designated it with '05'. At the time it was reported to be 140 nm (260 km) north-northeast of Tromelin Island. A few hours later, the MFR upgraded the disturbance into a tropical depression. The depression continued to intensify rapidly and on the same day, it became a Moderate Tropical Storm. Soon afterwards, the Joint Typhoon Warning Center (JTWC) started monitoring the system as Tropical Cyclone 13S. However, on 11 February, the central pressure started increasing and the system gradually weakened. On the next day, environmental conditions became very favourable for rapid strengthening, with no upper level wind shear and very good upper level divergence. The nearly-stationary system started intensifying again and became a Severe Tropical Storm, and soon a Tropical Cyclone, and then into an Intense Tropical Cyclone. But, due to interaction with land mass, Bingiza weakened into a Tropical cyclone, late on 13 February. Early on the next day, Bingiza made landfall over Saranambana, Madagascar and started weakening rapidly. As a result, the MFR downgraded it into an Overland Depression. The system slowly moved over Madagascar and crossed into the Mozambique Channel on 16 February, with the MFR reporting that the system became a Tropical Disturbance. As it entered water, it started intensifying and soon became a Tropical Depression. It briefly attained Moderate Tropical Storm status before making landfall and weakening to Tropical Depression strength. Bingiza later rapidly weakened as it crossed southern Madagascar, and dissipated on 20 February in the southern Indian Ocean.

As Bingiza neared land, rain and thundershowers hit Madagascar, causing flooding.

Tropical Cyclone Cherono (18S)
On 14 March, Tropical Low 23U crossed from the Australian region into the South West Indian Ocean basin, and was classified as Tropical Disturbance 07. It quickly strengthened the next day into a Tropical Depression, before being upgraded to Moderate Tropical Storm strength and being named Cherono. By 19 March, it was reported to be weakening and on 23 March Cherono dissipated.

Tropical Cyclone Dianne (16S)
A low developed off the Western Australian coast on 11 February and strengthened on 15 February. The Bureau of Meteorology issued a Cyclone watch later in the day reported that a tropical low formed 350 km NNW of Exmouth. A Cyclone watch had been issue for the coastal communities between Onslow to Coral Bay. Late on 16 February, the low formed into Tropical Cyclone Dianne whilst 445 km NW of Exmouth. Dianne, as expected, intensified, and was upgraded to a Category 2 cyclone on 18 February whilst slowly moving towards the SSW. On 19 February the system intensified into a Category 3 severe tropical cyclone. By late 21 February the system lost its strength as it moved into colder waters and was downgraded to a Category 1 Tropical Cyclone, and by 22 February it was classified as an ex-Tropical low.

Tropical Cyclone Yasi (11P)
Early on January 26, RSMC Nadi reported that Tropical Disturbance 09F, had developed within a surface trough, about 830 km (520 mi), to the northeast of Nadi, Fiji. During that day, the disturbance gradually organized further, before RSMC Nadi reported early the next day, that it had developed into a tropical depression. Over the next couple of days, the depression drifted towards the west, while gradually intensifying and organizing further. Late on January 29, the JTWC issued a tropical cyclone formation alert on the developing tropical depression, before designating it as 11P and initiating advisories on the system. Early the next day, RSMC Nadi reported that the depression had intensified into a category one tropical cyclone and named it Yasi, while it was located about 510 km (320 mi) to the northeast of Port Vila in Vanuatu. Yasi continued to intensify throughout that day, while affecting the Solomon Islands and Vanuatu. Early on January 31, RSMC Nadi reported that Yasi had intensified into a category two tropical cyclone, before reporting that it had become a severe tropical cyclone. During that afternoon, both the JTWC and RSMC Nadi reported that the system had moved across 160°E and had moved out of the South Pacific Basin and into the Australian region, where it became a much stronger storm before striking Queensland during the first days of February.
