Weather officials are warning that extensive areas of western and eastern Japan could face fresh flooding as a result of heavy rain, not long after they were hit by downpours that accompanied Typhoon Hagibis.
The Meteorological Agency says that as of 6:00 p.m. on Monday, severe tropical storm Neoguri had turned to a low pressure system over the sea south of the major island of Shikoku in western Japan.
Rain clouds are now stretching out along the Pacific coast of western and eastern Japan. The low pressure area accompanying the rain front is expected to move toward Japan's Pacific coast, from west to east.
The agency forecasts strong winds and high waves in many parts of the west and east of the country through Tuesday.
Heavy rain and lightning may hit the Pacific coast in areas from the Kinki region in the west to the Tokai and Kanto regions to the east.
In the 24-hour period until Tuesday evening, 300 millimeters of rain is forecast in Tokai, and 200 millimeters in Kinki and the Izu Islands.
In the Kanto-koshin region, 150 millimeters is expected, as well as 80 millimeters in the Hokuriku and Tohoku regions. In the following 24 hours, 50 to 100 millimeters are forecast in Tohoku.
Weather officials are warning of increased flood risks in areas where river banks were damaged by Typhoon Hagibis.
They say strong typhoon Bualoi is likely to approach the Ogasawara Islands between Wednesday and Thursday with increasing strength. It is expected to reach the waters east of Japan on Saturday, turning to a low pressure area.
