Gezani’s Category 3 Landfall: Madagascar’s 2026 Ruin and Recovery
According to the final Joint Typhoon Warning Center (JTWC) best-track archive, Cyclone Gezani dissipated over the Mozambique Channel in late February 2026, after carving a destructive path across eastern Madagascar. Gezani peaked at Category 3 intensity with verified maximum sustained winds of 109 kt (201 km/h) and a minimum central pressure of 956 hPa. Gezani struck near Tamatave (Toamasina), Madagascar’s principal port and second-largest city, on 10 February 2026, leaving 41 deaths, 427 injuries and 324,404 people directly affected across the Atsinanana Region. All meteorological metrics for Cyclone Gezani are verified against official best-track archives and UNICEF situation reports.
Genesis in the Southwest Indian Ocean: The Track of Cyclone Gezani
Cyclone Gezani reached the 109 kt (201 km/h) threshold on its approach to Madagascar, and Gezani’s 10 February 2026 landfall near Tamatave marked the climax of an accelerating westward journey across the Southwest Indian Ocean. The 2025–26 cyclone season had already demonstrated its destructive potential when Tropical Cyclone Fytia struck northwestern Madagascar on 31 January 2026. Gezani followed only ten days later, organizing over the open waters east of the Malagasy landmass and riding steering currents that directed it toward the Atsinanana coastline.
As Gezani closed on the coast, its forward motion brought the eyewall directly over Toamasina, the country’s principal port and a city of more than 300,000 residents. The port’s exposure to the Indian Ocean made it a natural landfall target, and the lack of significant island shielding meant that Gezani arrived with its core structure largely intact. After crossing the coast, Gezani weakened steadily as it encountered Madagascar’s eastern escarpment and central highlands, which disrupted the low-level inflow that had fueled the cyclone’s intensity.
Gezani emerged into the Mozambique Channel as a significantly weakened system. Humanitarian agencies tracking Gezani reported that it retained enough moisture to produce heavy rainfall and localized flooding in southern Madagascar, but the destructive core that had devastated Tamatave was gone. Gezani’s residual circulation drifted through the channel in late February before dissipating, closing a chapter that began with a tropical disturbance in the open Indian Ocean and ended with one of the most damaging cyclone impacts Madagascar had experienced in years.
The track of Gezani was notable for its directness. Unlike many Southwest Indian Ocean cyclones that recurve away from land, Gezani maintained a steady westward component that locked the Malagasy east coast into its crosshairs. The rapidity of Gezani’s approach compounded the challenge for emergency managers; the window between cyclone formation and landfall was compressed, limiting preparation time in a region still recovering from Fytia’s passage.
Peak and Fall: Gezani’s 956 hPa Category 3 Surge
At its verified peak intensity, Gezani carried maximum sustained winds of 109 kt (201 km/h) and a minimum central pressure of 956 hPa, placing Cyclone Gezani squarely at Category 3 on the Saffir-Simpson scale. UNICEF’s humanitarian reporting noted landfall gusts exceeding 250 km/h, consistent with the convective bursts of a major cyclone even though sustained winds define Gezani’s official classification. The 956 hPa central pressure represented a deep, well-organized storm, and the combination of wind and pressure placed Gezani among the stronger systems to strike Madagascar’s east coast in recent years.
Gezani’s intensity evolution followed a classic Southwest Indian Ocean development pattern. Warm sea surface temperatures in the basin provided abundant thermal energy, while modest vertical wind shear allowed Gezani’s core to consolidate. The cyclone deepened as it approached the coast, reaching its maximum intensity shortly before landfall. This timing is the worst-case scenario for a landfalling tropical cyclone: Gezani delivered its most violent winds and heaviest rain at the moment of impact, with no opportunity for offshore weakening.
Once over land, Gezani’s decline was rapid but not immediate. The crossing of Madagascar took most of a day, during which Gezani continued to produce torrential rainfall across the eastern escarpment. The mountains that define the island’s interior acted as a natural barrier, shredding Gezani’s low-level circulation and cutting off the warm, moist inflow from the Indian Ocean. By the time the system reached the Mozambique Channel, Gezani’s structure was severely degraded, and it no longer possessed the characteristics of a major cyclone.
The 956 hPa peak pressure and 109 kt sustained winds placed Gezani at Category 3 in the JTWC best-track analysis, a classification that carries specific operational significance. Category 3 and above are classified as major cyclones, capable of causing devastating damage even to well-constructed buildings. In Tamatave, where building standards are less robust and critical infrastructure is concentrated along the vulnerable coastline, the consequences of a direct Category 3 strike from Gezani were severe.
Direct Hit on Tamatave: The Wreckage Left by Gezani
When Gezani’s eyewall crossed the coast near Tamatave on 10 February 2026, the storm shredded the roofs of two university hospitals, collapsed 218 classrooms, and cut off every electricity and water network in the city. The human toll from Cyclone Gezani, as documented in UNICEF’s 14 February flash update, stood at 41 deaths and 427 injuries, with 324,404 people directly affected. Behind those figures lay a landscape of ruined homes and overwhelmed infrastructure that would take months, if not years, to rebuild.
The housing damage in the Atsinanana Region was catastrophic in scale. Assessments of the Gezani impact identified 21,267 flooded homes, 39,086 damaged homes, and 19,527 homes completely destroyed. The distinction between “flooded” and “destroyed” is critical for humanitarian response: flooded homes may be recoverable with cleaning and repairs, while destroyed homes require full reconstruction. Together, the three categories encompassed nearly 80,000 housing units, placing enormous pressure on shelter response capacities and displacement site management in Gezani’s aftermath.
Displacement figures reinforced the severity of the housing crisis caused by Gezani. An estimated 16,428 people lived in 48 designated displacement sites, with conditions described as challenging due to limited access to safe drinking water and healthcare. The displaced population included approximately 6,000 children in Tamatave I and II, raising immediate concerns about protection risks in crowded emergency shelters. The closure of the RN2, the city’s main arterial road, for three days slowed initial response movements and supply delivery, isolating Tamatave at the moment of greatest need after Gezani’s passage.
The destruction of critical infrastructure compounded the human tragedy of Gezani. Both university hospitals in Tamatave sustained major roof and facility damage, degrading the city’s ability to treat the 427 injured and manage ongoing medical needs. Twenty-one health centres in Tamatave II reported infrastructure damage, and vaccine cold-chain capacity was compromised in two facilities, threatening routine immunization programs. The Centre Vonjy, a specialized facility providing integrated services for child survivors of sexual violence, was heavily damaged by Gezani and rendered non-operational, eliminating a vital protection service at exactly the time displacement increased vulnerability.
The education sector suffered blows from Gezani that will be measured for years. Authorities reported 35 schools damaged, with 563 classrooms left without roofs and 218 classrooms destroyed, leaving approximately 29,000 students unable to attend classes. The loss of an academic year for nearly thirty thousand children represents a secondary disaster extending far beyond the immediate emergency. Even the central prison was not spared, with Gezani’s damage compromising separation arrangements and requiring the temporary relocation of 48 detained boys aged 13 to 17 within the facility.
Warm Waters and Steering Currents: The Meteorology Behind Gezani’s Track
Gezani intensified within a basin already primed by Cyclone Fytia, which had struck northwestern Madagascar on 31 January 2026, and the sequential one-two punch of Fytia and Gezani reflected an active phase of the Southwest Indian Ocean cyclone season. The meteorological environment that produced two landfalling cyclones in ten days was characterized by warm sea surface temperatures across the tropical Indian Ocean, a condition that has become increasingly common in recent years and that provides the thermal fuel for intense tropical cyclogenesis like that of Gezani.
The steering environment played an equally important role in Gezani’s track. Subtropical high pressure to the south of the cyclone channeled Gezani along a westward path, maintaining a consistent heading toward the Malagasy coast. The absence of strong mid-latitude troughs during Gezani’s approach meant that the cyclone was not recurved away from land, a fate that spares many Indian Ocean cyclones from landfall. Instead, the steering currents held Gezani on a collision course, and the lack of vertical wind shear allowed the cyclone to maintain its Category 3 intensity all the way to the coast.
The interaction between Gezani and Madagascar’s topography provided a natural laboratory for studying tropical cyclone decay. The island’s eastern escarpment, rising sharply from the coastal plain, disrupted Gezani’s low-level inflow within hours of landfall. The 956 hPa core pressure could not be maintained without the warm ocean energy supply, and rapid filling followed. Yet the orographic lifting of moist air over the escarpment produced extreme rainfall on the windward slopes, explaining why flooding and flash floods affected areas even beyond Gezani’s immediate landfall zone.
Ocean heat content was a significant factor in Gezani’s peak intensity. Deep, warm water in the Southwest Indian Ocean supports stronger cyclones by allowing oceanic mixing to draw from a larger heat reservoir. The 201 km/h sustained winds measured at Gezani’s peak are consistent with a system drawing on anomalously warm ocean conditions, and the rapid intensification phase that preceded landfall pointed to very favorable thermodynamic drivers. The exact sea surface temperature anomalies that fueled Gezani are a subject for post-season research, but the observed intensity of Gezani is consistent with broader trends toward more intense Southwest Indian Ocean cyclones.
Beyond the Wind: Gezani’s Secondary Disasters and Child Toll
Four days after Gezani’s landfall, UNICEF’s 14 February 2026 flash update catalogued 21,267 flooded homes and 16,428 displaced people, confirming that Gezani’s legacy was measured less in wind speed than in water and displacement. The phrase “secondary disaster” is often used loosely in humanitarian reporting, but in the case of Gezani it describes a concrete sequence of cascading failures: power lost, water contaminated, hospitals crippled, schools collapsed, and children left without safety nets.
The vulnerability of Madagascar to tropical cyclones is not new, but Gezani’s impact on Tamatave exposed the compounding risks of urban exposure and weak infrastructure. The city’s status as the principal port made the disruption of its electricity, water, and road networks a regional economic emergency, not merely a local one. The closure of the RN2 for three days interrupted not only humanitarian access but also commercial supply chains serving the entire eastern half of the country, amplifying the economic shock of Gezani far beyond the storm track.
Children bore a disproportionate share of Gezani’s burden. The estimated 6,000 displaced children across Tamatave I and II faced heightened protection risks in overcrowded shelters, and the loss of the Centre Vonjy eliminated a specialized service for child survivors of sexual violence. The destruction by Gezani of 218 classrooms and the damage to 563 more meant that 29,000 students could not return to school, interrupting not just education but also the protective environment schools provide during emergencies. The 48 detained boys relocated within the damaged central prison underscored the reach of Gezani into every corner of the city’s institutions.
The international response reflected the scale of the Gezani disaster. A high-level delegation visited affected areas on 12 February 2026, including the UN Resident Coordinator, representatives from UNICEF, IOM, and WFP, ambassadors from Japan and the United States, Germany’s Head of Cooperation, and senior officials from the African Development Bank and the European Union. The delegation met with the President of the Republic at the BNGRC Operational Centre. The President’s decision to travel to Tamatave ahead of Gezani’s landfall and remain through the storm signaled both the severity of the threat and the political stakes of the response.
For the global meteorological community, Gezani serves as a case study in the destructive potential of a Category 3 landfall in a vulnerable coastal city. Gezani did not achieve super typhoon or equivalent status; its 956 hPa central pressure and 109 kt winds place the cyclone in the middle range of major cyclones. Yet the damage in Tamatave rivaled that of far more intense systems, because the exposure and vulnerability of the affected population transformed a meteorological event into a humanitarian catastrophe. Gezani’s message is unambiguous: in the Southwest Indian Ocean, a Category 3 cyclone striking an unprepared coastline is not a moderate event. It is a disaster.
