Intense Tropical Cyclone Felleng was a powerful tropical cyclone that caused destruction across Seychelles, Madgascar, and Réunion. The seventh Tropical Disturbance, sixth named storm, and the third Intense Tropical Cyclone of the 2012–13 South-West Indian Ocean cyclone season, Felleng originated from an elongated, poorly organized area of convection associated with the remnants of Tropical Storm Emang lingered near the ITCZ.[1]

Felleng brought heavy rain to Seychelles, Madgascar, and Réunion. Which caused severe damage and killed 9 people.

Meteorological History

Map plotting the track and the intensity of the storm, according to the Saffir–Simpson scale

On January 18, an elongated, poorly organized area of convection associated with the remnants of Tropical Storm Emang lingered near the ITCZ.[2] By January 24, RSMC La Réunion reported a totally exposed vortex with occasional burst of convection persisted about 470 miles (755 km) NNE of Rodrigues, and 580 miles (935 km) SW of Diego Garcia. At that time it was not expected to strengthen,[3] but early on 26 January, convective activity improved, with deep convection and redeveloped a well defined, partially exposed low level circulation center due to moderate vertical wind shear from the East, and was designated as a Tropical Depression.[4][5] It continued to strengthen as it moved west, then south-west as it steadily intensified, reaching Intense Tropical Cyclone strength on 30 January while developing a well defined eye, with a deep, intense ring of convective banding forming in the eyewall.[6] On January 31 the eye became less well defined, and started to collapse.[7] On February 1 the system started to become elongated, and weakened into a severe tropical storm as it began its extratropical transition.[8] By February 3, Felleng became fully extratropical, with the low level circulation center becoming totally exposed and elongated, under vertical wind shear, located to the west of the remnant convection.[9]

Impact

Seychelles

Cyclone Felleng devastated the islands of Mahe, Praslin, and La Digue as a depression, many types of buildings were damaged and many farms were wiped out. Around 1,000 families were affected by floods and landslides, 246 of them were registered as displaced after their homes were damaged or destroyed.[10][11][12]

Madagascar

Cyclone Felleng brought heavy rain to Madgascar, due to which floodwaters rose rapidly in the capital Antananarivo, flooding many low-lying homes, as well as several hundred hectares of rice fields. Government authorities confirmed at least 800 people have been affected by the floods in the capital.[13][14] Across the island, 9 people were killed and 1,303 were left homeless. A total of 162 homes were destroyed while another 1,803 were damaged by floodwaters, most of which were in Vatovavy-Fitovinany.[15]

Réunion

Cyclone Felleng's heavy rain and strong winds caused damage in Réunion Island, where 11,200 homes were left without power.[16] Over the course of 72-hours, up to 800 mm (31 in) of rain fell in parts of the island, resulting in significant flooding. In Plaine des Cafres, 512 mm (20.2 in) fell within 24‑hours.[17]
