Severe Tropical Cyclone Kina was a significant tropical cyclone, which caused Fiji's greatest ever financial losses due to a tropical cyclone, with the total loss valued at near $F170 million ($US110 million). The system was first noted as a tropical depression, to the east of the Solomon Islands on December 23. Over the next few days the system moved south-eastwards and gradually developed further, before it was named Kina, after it had developed into a tropical cyclone during December 26.

Meteorological history

During the middle of December 1992, an active phase of the Madden–Julian oscillation took place which helped to reinforce atmospheric convection across the western Pacific Ocean.[1] A tropical depression subsequently developed, within this area of atmospheric convection in the monsoon trough to the east of the Solomon Islands during December 23.[1][2][3] Over the next couple of days the system moved south-eastwards and passed to the north-east of Temotu Province, before the Fiji Meteorological Service (FMS) started issuing warnings on it during December 26.[2][3] During that day the system rapidly developed further, before the United States Joint Typhoon Warning Center initiated advisories on the system and designated it as Tropical Cyclone 07P.[3][4] The systems subsequently relaxed for about twelve hours, before it started to steadily develop further during December 27.[3] The system was subsequently named Kina by the FMS, after it had become a category 1 tropical cyclone on the Australian tropical cyclone intensity scale.[3][5] After being named the system posed a threat to Vanuatu, as it moved south-eastwards and continued to develop further.[3]

During December 29, the JTWC reported that Cyclone Kina had reached its peak intensity with 1-minute sustained wind speeds of 220 km/h (140 mph), which made the system equivalent to a category 4 hurricane on the SSHWS.[2] At around the same time TCWC Nadi also reported that the system had reached its initial peak intensity, with 10 - minute sustained wind speeds of 150 km/h (90 mph) which made it a category 3 severe tropical cyclone on the Australian scale.[3][5] The system subsequently remained at its peak intensity until early on December 31, when it start to weaken and move eastwards towards the Yasawa island group.[3][5] During the next day as the system approached the Northern Yasawa islands, Kina turned sharply towards the southeast, which made it pass between Fiji's two main islands of Viti Levu and Vanua Levu.[3]

Preparations and impact

Severe Tropical Cyclone Kina impacted the island nations of Fiji and Tonga, while it also threatened Vanuatu during its developing stages.[3] Kina was one of the most destructive tropical cyclones to affect Fiji, with parts of the archipelago experiencing the full brunt of a cyclone, for the first time in twenty years.[3] Fiji also suffered its greatest ever financial loss from a tropical cyclone, as a result of Kinas strange track through the island nation.[3] Due to the impact of this system, the name Kina was subsequently retired, from the list of names for the region by the World Meteorological Organization.[6]

The systems rain bands started to impact the island nation during December 28, and over the next few days produced torrential rainfall throughout the archipelago.[3] Strong winds were observed in the islands during January 1 and gradually increased to hurricane force over the next few days, as the system passed virtually through the middle of Fiji.[3] As a result, most parts of the archipelago suffered moderate to severe damage was recorded, while 23 people were killed in Fiji by Kina mostly as a result of drowning and being struck by flying objects.[3]

Tonga

Late on January 2, the FMS issued a gale warning for the Tongan island groups of Haʻapai, Tongatapu and Vavaʻu, while the system was located about 555 km (345 mi) to the northwest of Nuku'alofa.[3] During the next day as Kina moved more towards the south-southeast than had been expected, a hurricane warning was issued for Tongatapu, while a storm warning was issued for Haʻapai.[3] Later that day the cyclone subsequently passed about 110 km (70 mi) to the southwest of Nuku'alofa.[3] The FMS subsequently downgraded the warnings to gale force as the system moved rapidly towards the south, before all warnings were cancelled early on January 4.[3] Within the islands major damage was confined to the Tongatapu group where the system caused a moderate amount of damages, with severe damage reported to food crops while a minimal amount of damage was reported to dwellings.[3] Within Nuku'alofa two people drowned, while another person was electrocuted.[3]

Wallis and Futuna

In conjunction with Kina, Nina affected Wallis and Futuna between January 3–4, however, there were no tropical cyclone warnings were issued for the French Territory by the FMS.[17][18] Kina affected Futuna during January 3, where sustained winds of up to 53 km/h (33 mph) and wind gusts of up to 69 km/h (43 mph) were recorded.[17] Nina affected Wallis Island later that day where sustained winds of up to 80 km/h (50 mph) and wind gusts of up to 68 km/h (42 mph) were recorded.[17][18][19] Within the islands some damage to crops and houses was reported.[17]

Tuvalu

After Severe Tropical Cyclone Joni had affected Tuvalu during the previous month, Nina and Kina indirectly impacted the island nation during the opening days of January 1993.[17][20][21] The systems contributed to the strength of the westerly winds that were already present over the islands, with winds of up to 130 km/h (80 mph) reported throughout the islands.[17][20] As these winds combined with a heavy westerly swell and high seas, where they caused flooding of up to 2 ft (0.61 m) over the islands of Nanumea, Nanumaga, Niutao, Nui and Vaitupu.[17][22] As a result, damage was reported to crops and several buildings in the island nation, including thirty houses.[20][23] The two cyclones caused a severe amount of erosion in the island nation, with the shoreline on Vaitupu, receding by about 5–6 m (16–20 ft).[21] The Vaitupu Fisheries Harbour, that had only just been built during 1992, was seriously damaged by waves attributed to the two cyclones.[24]

On the island of Nanumea, a poorly designed sea wall trapped the storm surge on the island, which caused salt water contamination of the island vegetation and killed several trees.[22] The An appeal for international assistance was subsequently made by the Government of Tuvalu, as supplied of food and other essentials like petrol and kerosene on the worst affected islands were running low.[20] International assistance was subsequently provided, by the United Nations Department of Humanitarian Affairs, who provided an emergency grant of US$10 thousand.[25] The European Commission also provided emergency aid to Tuvalu which enabled the Red Cross, to provide foodstuffs, shelter, medical supplies and utensils to people whose homes were destroyed.[26]
