TOKYO: Japan’s weather agency warned on Saturday of “unprecedented” risks from a “very dangerous” typhoon heading towards the southern island of Kyushu, urging residents to take shelter ahead of the storm.
Typhoon Nanmadol was producing gusts of up to 270 kilometres an hour and classed as a “violent” storm, the agency’s top level.
By late afternoon it was approaching the remote island of Minami Daito, 400km east of Okinawa.
The storm is expected to approach or make landfall on Sunday in southern Kagoshima prefecture on Kyushu, then move north the following day before heading towards Japan’s main island
“There are risks of unprecedented storms, high waves, storm surges, and record rainfall,” Ryuta Kurora, the head of the Japan Meteorological Agency’s forecast unit, told reporters.
“Maximum caution is required,” he said, urging residents to evacuate early. It’s a very dangerous typhoon.”
Kurora said the weather agency was likely to issue its highest alert later Saturday for the Kagoshima region.
Called “special warnings”, these are issued only when the JMA forecasts conditions seen once in a few decades.
It would be the first typhoon-linked special warning issued outside of the Okinawa region since the current system began in 2013.
“The wind will be so fierce that some houses might collapse,” Kurora told reporters, also warning of flooding and landslides.
An evacuation “instruction” — level four on a five-level scale — is already in place for 330,000 people in Kagoshima, and authorities urged people to move to shelters or alternative accommodation before a top-level call was issued.
Evacuation warnings in Japan are not mandatory, and during past extreme weather events authorities have struggled to convince residents to take shelter quickly enough.
Japan is currently in typhoon season and faces around 20 such storms a year, routinely seeing heavy rains that cause landslides or flash floods.
In 2019, Typhoon Hagibis smashed into Japan as it hosted the Rugby World Cup, claiming the lives of more than 100 people.
A year earlier, Typhoon Jebi shut down Kansai Airport in Osaka, killing 14 people.
And in 2018, floods and landslides killed more than 200 people in western Japan during the country’s annual rainy season.
Ahead of the arrivals of Typhoon Nanmadol, flight cancellations began to affect regional airports including those in Kagoshima, Miyazaki and Kumamoto, according to the websites of Japan Airlines and All Nippon Airways.
Scientists say climate change is increasing the severity of storms and causing extreme weather such as heat waves, droughts and flash floods to become more frequent and intense.
