In the country of Comoros; Kenneth's wind and rainfall caused at least seven deaths. Damage was estimated at US$345 million. Prior to Kenneth's landfall, local authorities evacuated over 30,000 people in the path of the storm in northern Mozambique. Kenneth killed 45 people in Mozambique.

Meteorological history

On 17 April, the MFR began monitoring a vortex to the north of Madagascar. The MFR continued to monitor the system over the next several days, noting a significant increase in deep convection on 21 April. On 22 April at 12:00 UTC, the MFR began issuing advisories on the system, designating it as Tropical Disturbance 14. Soon after, the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert, noting that the disturbance was located in a favorable environment with low vertical wind shear and warm sea surface temperatures of 29–30 °C (84–86 °F). Early on 23 April, the JTWC began issuing warnings on the system, classifying it as Tropical Cyclone 24S. A few hours later, the MFR upgraded the system to a tropical depression while it was moving west, under the influence of a low-to-mid-level ridge located to the south. The MFR upgraded the depression to a moderate tropical storm at 12:00 UTC, assigning the name Kenneth to the storm. At that time, the MFR stated that cloud top temperatures had decreased to −90 °C (−130 °F) and that the overall organization of the system had improved.

Soon after being named, Kenneth began to rapidly intensify, with the JTWC noting that a formative eye feature had developed. Around 00:00 UTC on 24 April, the MFR upgraded the system to a severe tropical storm. A few hours later, the JTWC followed suit, upgrading Kenneth to the equivalent of a Category 1 hurricane on the Saffir–Simpson hurricane wind scale. At 12:00 UTC, Kenneth was upgraded by the MFR into the record-breaking tenth tropical cyclone of the season. At that time, the MFR stated that an eye was attempting to form within the central dense overcast of the storm, and that wind shear was beginning to decrease. Around 18:00 UTC, Kenneth strengthened into the equivalent of a Category 3 major hurricane. At that time, the Hahaya International Airport on the Comoros island of Grand Comore reported winds of 36 knots (67 km/h; 41 mph) while Kenneth was located about 55 km (34 mi) to the north. Six hours later, the MFR upgraded Kenneth to intense tropical cyclone status, noting that the storm had a very cold convective ring and that the core had become more compact. On 25 April, at 06:00 UTC, Kenneth reached peak intensity, with 10-minute sustained winds of 215 km/h (134 mph) and a minimum central pressure of 934 hPa (27.58 inHg). At that time, Kenneth had a pinhole eye surrounded by very strong convection; however, the storm also began to undergo an eyewall replacement cycle. Meanwhile, the JTWC estimated that Kenneth peaked as a Category 4-equivalent tropical cyclone, with 1-minute sustained winds of 230 km/h (140 mph). As Kenneth approached the Mozambique coastline, the system slowly began to weaken due to the eyewall replacement cycle and the frictional effects of land interaction. Later that day, at 13:15 UTC, Kenneth made landfall in Mozambique as an intense tropical cyclone, just north of Pemba, with 1-minute sustained winds of 220 km/h (140 mph), equivalent to a Category 4 hurricane. This made Kenneth the most intense landfalling tropical cyclone in the recorded history of Mozambique. This also marked the second time in Mozambique's recorded history in which two storms have made landfall during the same cyclone season at intense tropical cyclone intensity or higher.

After landfall, Kenneth was re-classified as an overland depression, with 10-minute sustained winds of 155 km/h (96 mph), just below intense tropical cyclone strength. As the storm drifted further inland, it rapidly degenerated. Shortly afterward, the JTWC issued its last warning on the system. Kenneth's central convection had drastically shrunk, with only a small area remaining over land. Despite still being in a favorable atmospheric environment, Kenneth continued to rapidly weaken due to interaction with land. At 00:00 UTC on 26 April, the MFR issued its last warning on Kenneth, reporting 10-minute sustained winds of 65 km/h (40 mph), while the system was located about 110 km (68 mi) inland in Mozambique. Kenneth continued to weaken, with its winds falling below gale force as it continued its southward motion. On 27 April, thunderstorms developed off the coast of Mozambique, although the center of Kenneth remained over land, as the system began drifting northward. On 28 April, Kenneth emerged off the coast of northern Mozambique, but continued to weaken due to unfavorable conditions. Subsequently, Kenneth dissipated by 12:00 UTC on 29 April.
