Tropical Rainstorm Soudelor is now bringing heavy rain to parts of Japan and will continue to do so through Friday. As of Tuesday evening, the heaviest rains have tapered off across South Korea.

The former super typhoon took the lives of nearly two dozen people with several still missing in Taiwan and China.

After inundating eastern China with heavy rain from this weekend through Monday, Tropical Rainstorm Soudelor spread 25-60 mm (1.00-2.50 inches) of rain into South Korea on Tuesday.


The rain will shift into southwest Japan on Wednesday with northern Kyushu and southwestern Honshu getting the heaviest rainfall.

From Wednesday night into Thursday, the downpours will advance through central and north-central Honshu, focused mainly north and west of the Japanese Alps.

Rainfall of 25-50 mm (1-2 inches) will be common with localized amounts up to 100 mm (4 inches). This amount of rain is enough to cause flash flooding and continue the threat of mudslides.

"We expect locally heavy rain and isolated flash flooding in southern South Korea later Tuesday into Wednesday and in southern and central parts of Japan later Wednesday into Thursday," Leister said.

These areas will receive 25-50 mm (1-2 inches) of rain with local amounts of 100 mm (4 inches).

Winds in general will no longer be a threat from Soudelor. However, there can be locally gusty winds in any thunderstorms that accompany the heavy rainfall.


In the 24 hours ending Saturday night (local time), an observation site in the Wencheng District of Zhejiang Province was inundated with 420.2 mm (16.54 inches) of rain, according to Weather China.

Even as Soudelor exited China it was still producing heavy rainfall as more than 300 mm (12 inches) fell in only 24 hours in Dongtai to the north of Shanghai.
