On 4 February, a tropical disturbance formed 1,000 km (620 mi) northeast of Mauritius; assigned Zone of Disturbed Weather 10 by Météo-France and Tropical Disturbance 21S by the Joint Typhoon Warning Center. [4] [5] The disturbance proceeded to move erratically around its formation area. The disturbance then was officially recognized as a tropical depression by the JTWC. Around the same time, Météo-France also upgraded the storm from a zone of disturbed weather to a depression. The tropical depression proceeded to strengthen and erratically move to the southwest, keeping its depression status for a distance of 900 km (560 mi). In this state, the storm averaged a movement speed of 9 km/h (5.6 mph). [a] [1]

On 8 February, the tropical depression was officially upgraded to a moderate tropical storm by Météo-France; giving it the name Gezani. The JTWC also proceeded to classify Gezani as a tropical storm. [5] In this state, Gezani moved 50 km (31 mi) to the southwest at a relatively slow speed of 3 km/h (1.9 mph). The strengthening tropical storm continued by moving towards Madagascar, though at a slow pace of 7 km/h (4.3 mph). [b] The next day, Gezani underwent rapid intensification, inensifying from a moderate tropical storm to an intense tropical cyclone in just 24 hours. [5] [6] [1] In the process, Gezani developed a well defined eye. At 12:00 UTC, Gezani reached its peak intensity, sustaining wind speeds of up to 185 km/h (115 mph) and pressure levels as low as 953  hPa (mbar) over a 10-minute period. [4] Shortly after its peak intensity, at approximately 17:30 UTC on 10 February (7:30pm local time), Gezani made landfall near the city of Toamasina as an intense tropical cyclone, high end Category 3 on the Saffir-Simpson scale. [7] It was reported that Gezani's storm surge was 1 m (3.3 ft) high and traveling at 250 km/h (160 mph); accompanied by 10 m (11 yd) wave heights at this stage in the storm's lifespan. [8] [9] Satellite imagery displayed that the eye passed right over the city. [10]

Following the landfall, Gezani rapidly weakened; from an intense tropical cyclone to a severe tropical storm in a 12-hour window. That was then followed by the cyclone briefly becoming a tropical depression (disturbance on the MFR scale.) [1] On the 11 February at 18:00 UTC, Gezani had officially crossed Madagascar and lost all of its prior strength; travelling into the Mozambique Channel at about 25 km/h (16 mph). Then, bring present in the channel, it began strengthening in the warm water whilst steadily travelling west-southwest. [1] The strengthening process of the storm remained slow, increasing in intensity slightly at a time. [1] On 13 February at 00:00 UTC, the storm started showing signs of gradually turning south. Gezani narrowly missed Mozambique on its way south, briefly reaching its low end Category 3 secondary peak intensity of 185 km/h (115 mph), about 60 km (37 mi) east of Inhambane. The cyclone continued turning to its left–back to the east; whilst weakening in the process. [1] On 15 February at 00:00 UTC, the storm had completed its 180° turn to the left; continuing to weaken. This was followed by the cyclone approaching Madagascar, without making a secondary landfall. [1] After narrowly missing Madagascar, the cyclone proceeded to turn to the south, where on the 17 February it was downgraded to a moderate tropical storm. In the process, the cyclone moved over 1000 km south from when it was near Madagasacar–where it proceeded to become a subtropical cyclone. Over the next two days, Gezani would continue to weaken and on 20 February, Gezani dissipated. [1]

Preparations and impact

On 6 February, when the cyclone became a moderate tropical storm, The GDACS gave an overall red weather alert, expecting severe humanitarian needs following landfall. [11] The United Nations released $3 million from its emergency response fund to help Madagascar prepare for the impacts of Gezani. [12] The Mozambican government prepared in potential for effects, expecting it becomes a tropical cyclone in the Mozambique channel. [13] Cyclone Gezani came 10 days after Tropical Cyclone Fytia, which killed 14 and displaced over 31,000 people. [14]

In Madagascar, a total of 59 citizens have been found or reported dead; 32 in Toamasina Province and 27 elsewhere in the country. Alongside this, 804 have been injured and 15 people are currently labeled as missing in the country. [15] In the city of Toamasina 16,318 people were displaced from their homes alongside 269,407 classified as disaster victims in total. Toamasina also faced severe structural damage. 18,797 houses and 71 classrooms have been destroyed; as well as 51,760 houses and 561 classrooms being damaged. 104 classrooms were also labeled as being partially destroyed. [16] Overall, 75% of buildings were considered destroyed in the city, described by the locals as monstrous damage. [17] [18] In Inhambane, Mozambique, water services were cut off and 13,000 citizens were left without power; leaving four dead. [19] As a whole, $142 million of damage was reported in Madagascar. [10]

Compounding on the impacts of Cyclone Fytia, 400,000 people overall were left in humanitarian needs. [20] Michael Randrianirina, Madagascar's president, visited Toamasina to view the damage caused from the storm. [21] To help with the damage, China offered ¥100 million to cleanup after the destructive cyclone, and France pledged food and rescue teams from Reunion. [19] According to the CMRS cyclone forecaster on France's Reunion island, Cyclone Gezani's landfall is likely to have been one of the most intense recorded around the city in the satellite era. [3]

Notes

  1. These distance and speed figures are an approximation. IBTrACS does not keep data for tropical depressions, and the JTWC do not archive their storm warnings.
  2. This is Gezani's averaged movement speed, from when it became a tropical storm to when it made landfall.
