We’ve never seen such a downpour. So says Japanese forecaster Takuya Deshimaru amid heavy rains in the wake of Typhoon Etau. Tens of thousands have been ordered to flee their homes as officials issued warnings for prefectures north of Tokyo. Entire buildings have been swept away, several residents have been injured and one person is missing. In Fukushima Prefecture, rainwater has flooded the nuclear plant’s drains, sending contaminated water into the sea. Eastern Japan remains under threat as more precipitation is forecast through tomorrow, and the government remains on high alert.
