Weather tracker: Extreme rain deluges Japan and South Korea

Downpours break records and cause transport chaos, evacuations and deaths, as people get trapped inside vehicles

South Korea and Japan were hit by extreme rain late last week and into this week. On 13 August in the city of Chiba near Tokyo there was a record-breaking 115mm of rainfall in just one hour, while the nearby city of Sakura broke its own record with 97mm in one hour. Local authorities issued a level 5 emergency warning for heavy rain, the highest alert level and the first time one has been issued since the system was implemented in May.

More than 100,000 households were asked to evacuate, with more than 20,000 in the Chiba prefecture left without power, while thousands of people were stranded at Tokyo's Narita airport. Thirteen people have been confirmed dead, at least three of whom were found trapped inside their vehicles. One person is still missing.
