context_page_description: Cyclone Belna was a strong tropical cyclone that made landfall over northwestern Madagascar in December 2019, becoming the first to do so since Hellen in 2014. Belna's precursor—an initially broad trough of low pressure west of Seychelles—was formally designated as a zone of disturbed weather on 2 December during a favourable period for tropical cyclogenesis in the Indian Ocean. The disturbance gradually developed over the course of several days, tracking slowly westward. Météo-France upgraded the system to a tropical depression on 5 December and then to a tropical storm later that day. Belna reached tropical cyclone strength on 7 December as it began to turn towards the southwest, peaking with maximum sustained winds of 155 km/h before fluctuating in intensity over the following day as it passed just east of Mayotte. On 9 December, Belna restrengthened and reattained its peak winds upon making landfall near Soalala along the northwestern coast of Madagascar. The cyclone weakened before ultimately dissipating over southern Madagascar on 11 December.
  In the French overseas department of Mayotte, up to 15,000 people relocated to shelters in advance of the storm.
