The 2013–14 South-West Indian Ocean cyclone season is an event in the annual cycle of tropical cyclone formation that ended on June 30, 2014. The season officially began on July 1, 2013, though the first tropical system designated by Météo-France was a short-lived tropical disturbance that developed on July 8. However, the first named storm was Cyclone Amara in December. Bruce was the first very intense tropical cyclone since Edzani in 2010, which originated from the Australian region. The strongest system of the cyclone season was Hellen, also one of the most intense tropical cyclones over the Mozambique Channel.
Within this basin, tropical and subtropical disturbances are officially monitored by the Regional Specialised Meteorological Centre on Réunion island, while the Mauritius and Madagascar weather services assign names to significant tropical and subtropical disturbances.
The predecessor to the season's first designated tropical depression began as an area of persistent convection well removed from any landmasses. The JTWC began issuing products on the storm complex on October 21, noting recent consolidation patterns and its association with an ill-defined low-level circulation center. Over subsequent hours, the system developed a central region of convection with incipient rainbands. Despite these signs of potential tropical cyclogenesis in the very near future, the storm remained unclassified for several days as it tracked generally towards the west. At 1200 UTC on October 25, however, Météo-France classified the system as a tropical disturbance. Though upper-level atmospheric conditions were rather conducive for continued strengthening, factors including decreasing convergence and marginally sustainable sea surface temperatures were expected to inhibit tropical development, and as such initial forecasts only anticipated minimal and gradual strengthening.
