expected to allow for intensification. As a result, the Mauritius Meteorological Service named the disturbance as Fiona on March 16. On the next day, Fiona intensified into a tropical depression, reaching peak winds of only 55 km/h (35 mph). Also on March 17, the JTWC initiated advisories on Tropical Cyclone 28S. Around this time, Fiona passed about 200 km (120 mi) southeast of St. Brandon. After peaking, the convection decreased due to wind shear, causing the winds to fluctuate. On March 20, the circulation became exposed from the thunderstorms and approached 80 km (45 mi) east of Mauritius, producing wind gusts of 70 km/h (45 mph). The next day, Fiona dissipated into an approaching cold front.
422:. The depression turned to the south over land, remaining over inland Mozambique for several days. On January 18, the JTWC classified the system as Tropical Cyclone 13S, estimating winds of 65 km/h (40 mph), despite the storm being 55 km (35 mi) inland. The agency quickly downgraded the storm to tropical depression status, but briefly re-upgraded it on January 19 as the system crossed over the extreme western Mozambique Channel. The agency again downgraded it after the storm moved ashore. By contrast, the MFR assessed that the system remained a tropical depression and placed the circulation farther inland. On January 20, the depression turned to the southeast over open waters, influenced by a 549:
center. A trough behind the ridge allowed the system to turn to the southwest and later southeast. An increase in convection on February 15 organized into a curved band, and MFR upgraded the system to Tropical Storm Beltane on the next day off the west coast of Madagascar. The JTWC also classified the system as Tropical Cyclone 23S on February 16, possibly due to the extended duration between issuing advisories. Strong wind shear stripped the convection from the center as Beltane approached southwestern Madagascar on February 17. Another building ridge turned the weakened depression to the northwest across the Mozambique Channel, finally dissipating on February 20 near the mouth of the

intensify due to wind shear. On April 22, the system dissipated, never having developed beyond tropical disturbance status. The last disturbance of the year formed on July 20 about 1480 km (920 mi) east of Diego Garcia. The system moved generally southwestward, dissipating on July 23 due to wind shear. At the time, the tropical cyclone year for the basin lasted from August 1 to July 31 of the following year, although the JTWC considers the start of the tropical cyclone year to begin on July 1. As a result, the MFR considered the system Tropical Disturbance H4 while the JTWC classified it as Tropical Cyclone 01S.

of 100 km/h (60 mph). By contrast, the JTWC estimated winds of 165 km/h (105 mph), having classified it as Tropical Cyclone 27S that day. By that time, the storm was moving steadily to the southwest due to a trough in the region related to the remnants of Donaline. Increased wind shear caused steady weakening, removing the circulation from the convection on February 14. On the next day, Elsie weakened to tropical depression status as it curved southward. A building ridge to the south turned the system to the east, gradually looping back to the northwest. Elsie eventually dissipated on March 20.

ridge and a trough steered the storm to the southeast and later to the east. On April 9, Gemma attained peak winds of 85 km/h (55 mph), according to the MFR, while the JTWC estimated 130 km/h (80 mph) winds. As with most other storms in the year, increased wind shear caused the storm to weaken. The weaker system isolated it from the upper-level steering, causing the circulation to loop southwestward. On April 16, Gemma dissipated far to the east of Rodrigues.

In contrast, the JTWC estimated peak winds of 100 km/h (60 mph). The wind shear returned, causing weakening and dislocating the circulation from the convection. On March 10, Donaline became extratropical and was absorbed by a cold front two days later. 859: 654:. Shortly thereafter, Anacelle attained peak winds while presenting a 30 km (19 mi) eye. It reached peak winds of 140 km/h (85 mph), according to MFR, while the JTWC estimated peak winds of 215 km/h (135 mph). An approaching trough weakened the cyclone and steered it southeastward, causing the eye to disappear. On February 13, Anacelle became 438:. While the depression was over land, the plume of warm air from the open waters sustained heavy convection over the circulation, which dropped heavy rainfall across eastern Mozambique. The rains caused landslides and flooding in the country, which disrupted transport in three provinces, damaging several bridges. The most significant landslide occurred in 638:. The system slowly organized, aided by warm waters and weakening wind shear. On February 6, it developed into a tropical disturbance, and became Tropical Storm Anacelle two days later. Also on February 8, the JTWC initiated advisories on the storm as Tropical Cyclone 20S. The storm initially moved westward due to a 1068:

After the disturbance dissipated, a large low-pressure area persisted east of Madagascar with several associated circulations. On February 24, Tropical Disturbance D2 passed about 160 km (100 mi) west of Réunion, and continued to the southeast, passing south of Mauritius. Wind shear

After an extended period of inactivity, the ITCZ produced two areas of convection – one was located about 550 km (340 mi) south-southwest of Diego Garcia, and the other was located 900 km (560 mi) east-southeast of that system. Both were classified as tropical disturbances on

After Cyclone Anacelle became extratropical, an area of convection developed about 700 km (430 mi) northeast of Rodrigues on February 14. The circulation moved southwestward, organizing into Tropical Disturbance D1 on February 16. Later that day, it was upgraded to tropical

While passing near St. Brandon, Anacelle produced peak winds of 101 km/h (63 mph), with gusts to 151 km/h (94 mph). Later, the storm produced gusty winds of less than 120 km/h (75 mph) on Mauritius, along with 125 mm (4.9 in) of rainfall at
