TOKYO/SEOUL - Typhoon Khanun made landfall on the southeast coast of the Republic of Korea on Thursday after dumping heavy rain across southern Japan over the past week.

More than 1,500 schools have adjusted their schedules or closed because of the storm, with 877 switching to remote learning, the education ministry said

Warnings have been issued across the ROK, with more than 330 flights canceled and more than 10,000 people moved to safety.

The storm has brought up to 60 mm of rain per hour in areas on the east coast with maximum wind speeds of 90 kph in parts of Gyeongsang province and Jeju Island, the ROK's weather agency said.

Khanun is passing between Japan's main southwestern island of Kyushu, 860 km from Tokyo, and the Korean Peninsula, picking up a little speed as it moves north at 20 kph.

At least 14 people were injured in Kyushu due to the extreme weather conditions as Khanun drenched areas of Kyushu with a record rainfall, raising the risk of disaster, public broadcaster NHK reported.

The severe tropical storm left more than 12,000 households in Kyushu without power, it added.

Evacuation orders have been issued by a number of local governments in Kyushu, with over 6,000 people taking refuge in evacuation shelters in Kumamoto, Nagasaki, Miyazaki and Kagoshima prefectures.

The Japan Meteorological Agency (JMA) said Khanun's slow advance caused rain clouds to linger, adding that some areas of Kyushu and Shikoku received more than 450 mm of rain in the 24 hours through 3 am Thursday.

Authorities in Kyushu and Shikoku warned of possible weather-related disasters as the storm continues to lash the islands.

In the ROK, outdoor activities have been halted for participants of the World Scout Jamboree. About 37,000 scouts were on Tuesday moved out of their campsite in the path of the storm to safer accommodation.

More than 1,500 schools have adjusted their schedules or closed because of the storm, with 877 switching to remote learning, the education ministry said.

The ROK is still recovering from intense monsoon rain last month, when more than 40 people were killed in floods and landslides, including 14 in a flooded tunnel.

The Democratic People's Republic of Korea is also bracing for the storm, with Khanun expected to barrel through its capital, Pyongyang. Sand bags and pumps had been prepared in vulnerable areas, the KCNA state news agency reported on Wednesday.

But attention was already turning to another storm, Typhoon Lan, which passed near the Ogasawara Islands, about 1,000 km south of Tokyo, late on Wednesday and was heading north, northwest at 15 kph.

Though the storm's path was uncertain, the Japan Meteorological Agency (JMA) said it could affect the Tokyo area towards the end of the weekend.

The bad weather is striking in the middle of Obon, Japan's main summer holiday when many people leave big cities to return to their home towns.
