On Monday, South Korea upped its typhoon warning to the highest level as Typhoon Hinnamnor triggered airline cancellations, the suspension of certain commercial activities, and the closure of schools.

As the typhoon came from the south at a pace of 33 kilometers per hour, heavy rain and high winds lashed the country’s south (20.5 mph). After passing over the holiday island of Jeju on Monday, Hinnamnor is predicted to make landfall southwest of the port city of Busan early Tuesday.

President Yoon Suk-yeol said he would be on emergency standby, a day after ordering authorities to do their best to minimise damage from the typhoon.

“Very strong winds and heavy rains are expected across the country through to Tuesday due to the typhoon, with very high waves expected in the coastal region along with storm and tsunami,” the Korea Meteorological Administration (KMA) said.

Hinnamnor is on a course that will take it northeast toward Sapporo, Japan, it said.
