Typhoon Chanthu is expected to pass the South Seas of South Korea on Friday and bring heavy rainfall of up to 300 millimeters over the island of Jeju and the southern region of the country. However, with the typhoon heading east on Saturday, the Korean Peninsula will be sidelined during the Chuseok holiday.
According to the Korea Meteorological Administration (KMA) on Tuesday, Typhoon Chanthu heads southeast at 3 p.m. on the same day from the sea 280 kilometers from Shanghai. It retains a strong influence with the central pressure of 975 hPa and the maximum wind speed of 35 meters per second.
The KMA forecast the typhoon will stay near Shanghai until Thursday morning before spilling over to the Korean peninsula that afternoon. It is supposed to travel across the southwestern sea of â€‹â€‹Jeju Island and reach the sea on Friday afternoon about 50 kilometers from Busan in a southerly direction. As it approaches the peninsula, the force of the typhoon will hold the lower median level.
Heavy rains are expected during the typhoon – 100 to 200 millimeters on Jeju Island (over 300 millimeters in some areas), 20 to 80 millimeters in South Jeolla Province and in the southern sea of â€‹â€‹South Gyeongsang Province (over 120 millimeters in some areas) and 10 to 40 millimeters in the provinces of South Gyeongsang, North Jeolla and North Gyeongsang – by Wednesday.
When the typhoon approaches the Korean peninsula on Thursday and Friday, rainfall levels on Jeju Island could reach 50 to 150 millimeters (over 300 millimeters in some areas) and also in the Southern Sea of â€‹â€‹South Jeolla Province, the sea of â€‹â€‹the Gyeongsang region, and near Mount Jiri (over 250 millimeters in some areas). In some regions there will be a maximum rainfall of over 80 millimeters per hour during this time. The maximum wind speed can reach 40 meters per second on Jeju Island, the South Pacific and the Eastern Sea of â€‹â€‹the Gyeongsang region. Typhoon Chanthu is expected to travel across the South Seas before setting off for the southeastern ocean of Ulleung Island and the Dokdo Islands off the peninsula early Saturday morning.
