South Korea classifies typhoons in four categories – normal, strong, very strong, super strong – and Hinnamnor is expected to reach the country as a “very strong” typhoon, according to the KMA. Typhoons under that classification have wind speeds of up to 53m per second.
Warnings have been issued across the southern cities, including Gwangju, Busan, Daegu and Ulsan, following that in the southern island of Jeju, while the Central Disaster and Safety Countermeasures Headquarters on Sunday upgraded its typhoon alert level to the highest in its four-tier system, the first time in five years.
Busan city and its neighbouring areas have received rain throughout the weekend, with more rain forecast across the wider country for Monday and Tuesday.
No casualties have been reported so far, though more than 100 people have been evacuated and at least 11 facilities have been damaged by floods.
