The Japan Meteorological Agency (JMA) said the storm is now moving north across Japan’s third largest island, Kyushu, and is expected to bring strong rain throughout the week.
Nearly 10 million people in Kyushu have been advised to seek shelter in sturdy buildings or move to higher ground before the storm arrived on Sunday. Such warnings are not mandatory and authorities have struggled in the past to encourage people to leave their homes. On Sunday, Kyushu authorities took the unusual step of issuing a rarely used “special warning” in hopes of conveying the gravity of the threat posed by the storm.
The JMA has warned that a “large-scale catastrophe” may be imminent with widespread flooding and landslides. “The highest level of vigilance is required for rising waters, river floods, landslide disasters and lowland floods,” she said on Sunday.
Kyushu Electric Power Corporation said many prefectures, including the cities of Fukuoka and Nagasaki, have been out of power since the typhoon arrived on Sunday. The authorities added that at least 17 people were injured so far from the cyclone.
Experts have warned that Nanmadol is expected to travel to central Japan towards Tokyo in the coming days and will maintain its strength as it moves.
Ferry and express train services, as well as hundreds of flights across the country, have been canceled due to the dangerous weather.
Residents were asked to remain alert to avoid possible aftershocks.
