In the South-West Indian Ocean, Météo-France's La Réunion tropical cyclone centre (MFR, RSMC La Réunion) monitors all tropical cyclones. A very intense tropical cyclone (VITC) is the highest category on the South-West Indian Ocean Tropical Cyclone scale, and has winds of over 115 knots (212 kilometres per hour, 132 miles per hour).[1] The most recent very intense tropical cyclone was Cyclone Faraji in 2021.

Background[]

The South-West Indian Ocean tropical cyclone basin is located to the south of the Equator between Africa and 90°E.[2] The basin is officially monitored by Météo-France who run the Regional Specialised Meteorological Centre in La Réunion, while other meteorological services such as the Australian Bureau of Meteorology, Mauritus Meteorological Service as well as the United States Joint Typhoon Warning Center also monitor the basin.[2] Within the basin a very intense tropical cyclone is a tropical cyclone that has 10-minute mean maximum sustained wind speeds of over 115 kn (215 km/h; 130 mph).[2]

Other systems[]

The Mauritius Meteorological Service classifies Dina in 2002 as a Very Intense Tropical Cyclone.[26] The Australian Bureau of Meteorology estimates that Severe Tropical Cyclone Daryl–Agnielle 1995 peaked with 10-minute sustained winds of 220 km/h (140 mph), which would make it a Very Intense Tropical Cyclone.[27] However, RSMC La Réunion shows that the system peaked with 10-minute sustained winds of 175 km/h (110 mph) which makes it an Intense Tropical Cyclone.[27]
