drifted to the east, strengthening to tropical depression status on January 22, and passing 330 km (205 mi) west of Réunion. Increased wind shear caused the system to weaken as it turned back to the west, dissipating over Madagascar on January 24. On Réunion, the system dropped about 100 mm (4 in) of rainfall, including a total of 50 mm (2 in) falling in a 90-minute period in Cape Bernard. On January 23, a weak tropical low began affecting Mozambique for two days, causing flooding that killed six people. Although newspaper sources indicated that the system was a tropical storm, it remained unclassified by MFR. Toward the end of January, a broad low persisted south of the Chagos archipelago, becoming a tropical disturbance on January 30 about 650 km (400 mi) south of Diego Garcia. 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. Initially the circulation was very broad, and due to its involvement with the monsoon, it resembled a monsoon depression. Early on February 1, the disturbance intensified into a tropical depression while turning more to the south. Around that time, it passed about 500 km (310 mi) east of Rodrigues. The system became extratropical on February 3, after increased wind shear weakened the convection. The former depression intensified as an extratropical storm, attaining gale-force winds while accelerating its forward motion due to an approaching trough. The system was no longer tracked after February 6 as it approached the polar latitudes. 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. By April 19, it had organized into a subtropical depression and produced gale-force winds. The MFR did not classify the system, however, due to it being located from 33 to 35° S, which was outside of the agency's area of warning responsibility at the time. Storm names A tropical disturbance is named when it reaches moderate tropical storm strength. If a tropical disturbance reaches moderate tropical storm status west of 55°E, then the Sub-regional Tropical Cyclone Advisory Centre in Madagascar assigns the appropriate name to the storm. If a tropical disturbance reaches moderate tropical storm status between 55°E and 90°E, then the Sub-regional Tropical Cyclone Advisory Centre in Mauritius assigns the appropriate name
