Record-breaking torrential rains and deadly floods hammer Japan – Videos

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.”

  1. rereading those rainfall amonts and the duration…
    the timeframe its been happening and ongoing is the real whammy, a day or so then time for things to runoff n dry out a bit just isnt happening
    not a geologist but I seem to remember a lot of their land areas have porous rocky fairly well draining structures ie how the water from Fuku trashed areas was draining to sea unchecked.
    it may be a good thing for their buildings if a fair whack of the land does do that, if not then subsidences are going to be an ongoing issue as well
    they dont mention reservoir levels etc?
    not much manmade could hold river flows like those shown anyway

  2. Been lots of damage, people cut off, no power flooded towns, fields, people getting washed away. Further north where we are, while it has not been as bad we have had rain everyday this month except one. No sun, cool temps and lots of rain. And this weather is set to continue. So far we haven’t had summer just a very, very long spring.

  3. Back in June this weather pattern started as a cyclone/monsoon event in the Indian Sea and slowly traveled northeasterly over India, the Tibet plain, the Yangtze valley, and now Japan. This storm just doesn’t seen to be losing any energy. I suspect that it will gather more energy when it finally heads out over the Pacific. I am hopping it will continue its trajectory and land in Alaska / Canada and not track south into the Inland Northwest. It is getting close to grain harvest time and a crop loss this year would be bad news for a lot of our farmers
