The annual cyclone season began on November 15, 2015, with the first storm, Annabelle, forming four days following. The final and strongest storm, Fantala, dissipated on April 23, 2016, a week before the season ended on April 30 for most of the region.Le coin de l'éducation / FAQ G: Climatologie February 26, 2017 http://www.meteofrance.re/cyclone/FAQ/G Météo-FranceSeptember 2026 InternetArchiveBot In Mauritius and the Seychelles, the cyclone season ended half a month later, on May 15. The season's activity was influenced by an ongoing El Niño, and a positive Indian Ocean Dipole. The South-West Indian Ocean basin consists of the portion of the Indian Ocean west of 90°E and south of the Equator. Tropical cyclone activity was monitored by Météo-France office in Réunion, the Regional Specialized Meteorological Centre for the basin. The basin is also unofficially monitored by the Joint Typhoon Warning Center, which uses one-minute sustained winds to estimate wind speeds within systems, while Météo-France uses ten-minute sustained winds and its own intensity scale. Eight moderate tropical storms in total developed or existed within the bounds of the basin, slightly below the average of ten. Most systems during the season remained weak, with only three storms (Uriah, Emeraude, and Fantala) reaching at least tropical cyclone strength with winds of 65 kn km/h mph out on 5, compared to the average of five. However, the season featured Cyclone Fantala, which became the strongest tropical cyclone on record in the basin in terms of 10-minute sustained winds at 135 kn km/h mph out on 5 and in terms of 1-minute sustained winds at 155 kn km/h mph out on 5. __TOC__ Seasonal forecasts On October 19, the Mauritius Meteorological Services (MMS) released their summer 2015–16 outlook. An average season, with around seven to nine cyclones forming, was expected. MMS also indicated that the equatorial region to the north of Mauritius, east of Agaléga and west of Diego Garcia, could be significantly conducive for cyclone formation.October 19, 2015 Summer 2015–2016 Outlook for Mauritius and Rodrigues https://web.archive.org/web/20151018183151/http://metservice.intnet.mu/news-details-3.php Mauritius Meteorological Services http://metservice.intnet.mu/climate-services/seasonal-climate-forecast.php October 18, 2015 October 20, 2015 live Météo-France issued their seasonal forecast of cyclone activity for the basin on November 12. MFR predicted a slightly below average to average season, citing the effects of a very strong El Niño event. Compared to an average of ten moderate tropical storms that usually form in the South-West Indian Ocean, a 70% chance was given to the probability of six to ten named storms forming. A 20% chance was given to the formation of only five cyclones or less, and a 10% was given to an above average level of activity. MRF expected that an above average number of named storms would develop in the central region of the basin (from 60°E to 77°E), and that there would be lower than average activity to the east of 77°E. Activity near normal was expected west of 60°E. MFR also predicted that the motion of cyclones during the season would have a stronger meridional component than normal, having a tendency to track south quickly.Prévision saisonnière d'activité cyclonique dans le Sud-Ouest de l'océan Indien : Saison 2015-2016 April 7, 2016 http://www.meteofrance.re/actualites/cp_saisoncyc2015_2016 Météo-France April 4, 2016 dead November 12, 2015 https://web.archive.org/web/20160404201137/http://www.meteofrance.re/actualites/cp_saisoncyc2015_2016 Seasonal summary The season started on November 19, with the formation of Annabelle. After a month of inactivity, Bohale formed, but was fairly weak and only reached moderate tropical cyclone strength. Another month passed before Corentin formed on January 20. In February, the basin became somewhat active with Daya forming, and Uriah entering the basin days later. Emeraude formed in March, quickly peaking at intense tropical cyclone strength, before quickly weakening. Moderate Tropical Storm 07 formed at the end of March. In April, the season began to wind down. Very Intense Tropical Cyclone Fantala formed near the end of the month, and reached peak intensity as the strongest tropical cyclone recorded in the basin in terms of sustained winds. Fantala dissipated on April 23, ending the season.FANTALA : 10/04/2016 TO 26/04/2016 http://www.meteo.fr/temps/domtom/La_Reunion/webcmrs9.0/anglais/archives/saisons_archivees/20152016/2015RE08.html Météo-France February 26, 2016 Systems Severe Tropical Storm Annabelle SWI Annabelle 2015-11-23 0520Z.jpg Annabelle 2015 path.png November 19 November 23 55 60 983 Météo-France first noted a zone of disturbed weather about 930 km (580 mi) east-northeast of Diego Garcia on November 18.

The system weakened due to an eyewall replacement cycle, and a change of steering currents caused Fantala to reverse direction and accelerate southeast. This brought the cyclone over cooler waters previously upwelled by itself, causing further weakening. Between April 19 and 23, Fantala fluctuated in intensity. At first, the eye became more pronounced,Météo-France National Oceanic and Atmospheric Administration April 19, 2016 April 21, 2016 Very Intense Tropical Cyclone 8 (Fantala) Warning 32 http://weather.noaa.gov/pub/data/raw/wt/wtio22.fmee..txt https://archive.today/20240522003822/https://www.webcitation.org/6gtUl9tsS?url=http://gwydir.demon.co.uk/advisories/WTIO30-FMEE_201604181238.htm May 22, 2024 live but wind shear soon caused weakening to resume. By April 22, Fantala stalled again due to a building ridge to its south. Fantala accelerated back northwest as a moderate tropical cyclone, with the JTWC and MFR issuing their final advisories on April 24. The remnants of Fantala continued northwest toward the East African coast. Evacuations were initiated on Agaléga ahead of Cyclone Fantala.Agaléga: 72 Personnes Évacuées á L'Approche du Cyclone Fantala Le Defi Media Group 15 April 2016 22 April 2016 http://defimedia.info/agalega-72-personnes-evacuees-a-lapproche-du-cyclone-fantala-25166/ French https://web.archive.org/web/20160423135943/http://defimedia.info/agalega-72-personnes-evacuees-a-lapproche-du-cyclone-fantala-25166/ 2016-04-23 dead While near peak intensity, the cyclone also passed near the Farquhar Group of the Seychelles, damaging most of the buildings in the small archipelago.Sharon Urinie April 20, 2016 April 21, 2016 Seychelles authorities declare Farquhar islands disaster areas after Cyclone Fantala hits twice Seychelles News Agency http://www.seychellesnewsagency.com/articles/5017/Seychelles+authorities+declare+Farquhar+islands+disaster+areas+after+Cyclone+Fantala+hits+twice The islands were declared a disaster area by Seychelles officials.

Tanzania Lexis Nexis Storm names Within the South-West Indian Ocean, tropical depressions and subtropical depressions that are judged to have 10-minute sustained wind of at least 35 kn km/h mph out on 5 by the Regional Specialized Meteorological Center on La Réunion Island, France (RSMC La Réunion) are usually assigned a name. However, it is the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar who name the systems. The Sub-Regional Tropical Cyclone Advisory Center in Mauritius names a storm should it intensify into a moderate tropical storm between 55°E and 90°E. If a storm should intensify into a moderate tropical storm between 30°E and 55°E then the Sub-Regional Tropical Cyclone Advisory Center in Madagascar assigns the appropriate name to the storm. New name lists are used every year, and a name is normally only used once, so there are currently no retired names, however should a name go unused during a season, the name could be re-used in future seasons.2010 Tropical Cyclone Operational Plan for the South-West Indian Ocean 2012-06-07 Regional Association I Tropical Cyclone Committee World Meteorological Organization http://www.wmo.int/pages/prog/www/tcp/documents/TCP-12_2010_English.pdf Annabelle Bohale Corentin Daya Emeraude Fantala Gao Hassina InacioJuma Ketiwe Lalelani Moabi Naima Octave Piera Quizito RichardSofia Tatiana Umboni Vela Wayne Xaba Yazid Zenani Seasonal effects This table lists all of the tropical cyclones and subtropical cyclones that were monitored during the 2015–2016 South-West Indian Ocean cyclone season.
