Torrential downpours bring flooding risk to Japan into Tuesday night
The warmth spanning Japan and the Korean Peninsula this past weekend will be whisked away by a storm which will bring the risk of flooding downpours early this week.
Japan will become cooler and wetter through Tuesday night.
Rain totals of 50-100 mm (2-4 inches) with locally higher amounts are expected. Flash flooding may result in low-lying and poor drainage areas. Streams can overflow their banks.
Areas that have received soaking rain recently will be more susceptible to flooding.
Isolated mudslides may also occur, mainly along the southwest-facing slopes of the mountains.

Following widespread downpours across the Korean peninusla late in the weekend, the downpours shift eastward across Japan and will persist into Tuesday night.
Tokyo may escape the heaviest rain and greatest risk for flooding. However, the rain that targets the city on Tuesday night and early Wednesday morning can still be enough to lead to travel delays.
Throughout Japan, downpours can reduce visibility for motorists and heighten the risk of vehicles hydroplaning when traveling at highway speeds.
Gusty winds may also buffet the southern coast of Japan as the storm moves through.
At midweek, the storm is expected to dampen northern Japan as drier and seasonable conditions prevail over southern and western parts of the country and the Korean Peninsula.
