Heavy rain pounded parts of western Honshu and the Kyushu region on Saturday, with record-breaking hourly precipitation reported in several locations, causing one fatality and leaving two others missing, local authorities and the weather agency said.
The Meteorological Agency on Sunday continued to warn of the danger of landslides and flooding in low-lying areas, as well as the rising and overflowing of rivers in Kyushu, especially its southern areas, due to possible heavy rainfall through Monday.
The agency said a weather front that is expected to stay near Kyushu over Monday will see warm and moist air flowing toward it, making the atmospheric conditions very unstable.
