Three inches of rain per hour – Moe than 3 feet in 3 days.
A week of torrential rain pounded southwestern and central Japan, triggering severe flooding and landslides that killed at least 68 people. Kumamoto prefecture in Japan’s southern island of Kyushu has been hardest hit, and over the weekend residents braced for more extreme weather. On Saturday some areas observed more than 80 mm (3.15 inches) of rainfall per hour and 1,000 mm (more than 3 ft) over three consecutive days. Strong winds, lightning, and tornadoes were also added to the weather warning. The Ministry of Land reported 282 mudslide disasters across 27 prefectures with the largest number, 52, in Kumamoto prefecture.
Eastern and western Japan are on high alert for heavy 24-hour downpours with a risk that rivers in Iwate and Aomori could overflow. New mudslide warnings have also been issued for Kyushu as past rain loosens the ground and damaged river levees inundate low-lying areas.
Japan’s Meteorological Agency says the atmospheric conditions remain unstable over a wide area from western Japan to Tohoku as a result of an active weather front and low pressure system extending over the East China Sea to the Sea of Japan. Local heavy rains are expected to continue for 12 to 15 days.

“That’s some massive rainfalls,” says Laurel. “Hope they sorted out their backup generators OUT of basements after fukushima.”
