Heavy rain hit southern Kyushu in southwestern Japan on Sunday, prompting the weather agency to warn of possible landslides, flooding in low-lying areas and swollen or overflowing rivers.
Linear rainbands — zones of heavy rain clouds that form in succession over the same area — could develop in Miyazaki and Kagoshima prefectures through late Sunday morning, sharply increasing the risk of disasters, the Japan Meteorological Agency said.
Atmospheric conditions are likely to remain highly unstable across western Japan, with Shikoku, one of Japan’s four main islands, also possibly facing rainfall heavy enough to trigger warnings, the agency added.
According to the agency, a weather front extends from the Chinese mainland through the Nansei Islands in southwestern Japan to the south of the country, while a low-pressure system over the East China Sea along the front is moving east-northeast.
Warm, moist air is flowing toward the front and low-pressure system, causing heavy rain with thunder in parts of western Japan and the Nansei Islands.
By 6 a.m. Monday, rainfall in the 24-hour period is expected to reach up to 300 millimeters in Shikoku and 150 mm in southern Kyushu and the Amami region.
