Ando would become the most intense cyclone of the year, reaching peak winds of 195 km/h (121 mph) according to the Météo-France office (MFR) on Réunion, the official Regional Specialized Meteorological Center for the basin.

The others were Bindu, which alternated its trajectory several times over open waters, and Charly, which rapidly weakened after encountering hostile wind shear.

The next storm to form was Tropical Cyclone Dera, which intensified near Mozambique in early March and killed two people there due to flooding rains.

[3] On August 1, in the middle of the southern hemisphere's winter,[3] an area of convection persisted in the northeastern portion of the basin about 740 km (460 mi) northeast of Diego Garcia.

[5][6] The beginnings of Ando can be traced to a circulation within the Intertropical Convergence Zone (ITCZ) about 400 km (250 mi) south-west of Diego Garcia, which became evident on satellite imagery on December 30.

After the shear subsided, the system intensified into a moderate tropical storm on January 2, given the name "Ando" by the Mauritius Meteorological Service.

[3] Also on that day, the JTWC began issuing advisories on the storm as Tropical Cyclone 04S, and around that time, Ando was passing about 465 km (289 mi) east-southeast of Agaléga island.

[8] Ando rapidly intensified after forming and attained tropical cyclone status early on January 4,[7] developing an eye in the center of the thunderstorms and outflow to the east.

Late on January 4, the storm intensified further into an intense tropical cyclone, and early the next day passed about 120 km (75 mi) northeast of Tromelin Island.

[7] In contrast, the MFR assessed Ando as weakening due to the becoming larger and less defined, while still maintaining a small cloud diameter of about 400 km (250 mi).

Continuing around the ridge, the cyclone passed about 205 km (127 mi) west of Réunion that day before starting to weaken due to increased wind shear.

Most parts of the island did not receive much rain, with the exception of mountainous peaks due to orographic lift, particularly after the center passed to the west.

[3] On January 2, an area of convection persisted in the eastern portion of the ITCZ in the Australian basin, located northwest of Cocos Island, or about 1,165 km (724 mi) southwest of Sumatra.

Early on January 9, the MFR upgraded the storm to tropical cyclone status as an eye 19 km (12 mi) in diameter formed.

The next day, Bindu weakened due to increased wind shear, causing the circulation to be exposed from the convection and for the cyclone to be downgraded into a severe tropical storm.

At 18:00 UTC the next day, the storm passed about 140 km (87 mi) southeast of Rodrigues island, by which time the circulation was exposed north of the dwindling convection.

[8] Based on the increased organization, the storm became an intense tropical cyclone,[3] reaching peak 10 minute winds of 185 km/h (115 mph), according to the MFR.

The eye rapidly dissipated as the convection dwindled,[3] and within 24 hours of peak intensity, Charly was downgraded to tropical storm status.

[12] The convection gradually organized as the system moved to the south-southwest, steered by a break in the ridge to the south caused by the remnants of Cyclone Charly.

The former depression intensified as an extratropical storm, attaining gale-force winds while accelerating its forward motion due to an approaching trough.

With warm waters and an anticyclone providing outflow, the depression quickly intensified, becoming Tropical Storm Dera on March 9 and soon after developing an eye feature.

Wind shear increased on March 12, and only on that day did water temperatures drop off, causing a marked decrease in intensity and for the eye to dissipate.

[3] The ITCZ became active in late March, spawning several areas of convection across the Indian Ocean and into the adjacent Australian basin.

Drifting to the southwest and later to the south, the associated convection waxed and waned, finally organizing more on April 4; on that day, the disturbance quickly intensified into Moderate Tropical Storm Evariste.

Late on April 7, the storm suddenly turned southwestward toward a developing low east of Madagascar, although the southwest motion resumed soon after.

[3] A small area of convection not associated from the ITCZ became Tropical Disturbance 10 on April 1, about 215 km (134 mi) west-northwest of the Cocos Islands in the Australian region.

However, data from QuikSCAT helped upgrade the system to moderate tropical storm status in a post-season analysis, with peak winds of 65 km/h (40 mph) on April 3; as a result, it was not named.

[3] It underwent the Fujiwhara effect with a larger disturbance to the east,[15] causing the system to turn back to the north and dissipate on April 5.

Turning to the northeast and east, the subtropical storm rapidly weakened on June 22 to depression status after the environment became hostile, and the convection largely dissipated.

[8] On April 17, a weak low exited from the coast of South Africa and moved southeastward over the warm waters of the southern Mozambique Channel.
