Japan warned residents in Amami and southern Kyushu to prepare for torrential rain on Tuesday (2 June), after Severe Tropical Storm Jangmi battered Okinawa, injuring more than 10 people and cancelling hundreds of flights.

People on Japan’s Amami Islands were bracing for the storm as weather officials warned that southern Kyushu and Amami could face torrential rain, strong winds, high waves and the risk of landslides.

The Japan Meteorological Agency said the storm was west-northwest of Amami as of 7 a.m. on Tuesday. NHK reported that strong winds had already damaged parts of Okinawa and injured more than 10 people.

The storm could bring up to 350 millimetres of rain to the Kinki region in 24 hours, while heavy rain was also possible along Japan's Pacific coast as Jangmi approached, according to NHK.

Warnings move north

Weather officials said they may issue Level 4 alerts, a category NHK described as an urgent warning that means people should evacuate from dangerous areas. Officials urged residents not to delay preparations as rain bands and strong winds spread beyond Okinawa.

Reuters video from Naha showed trees bending in powerful gusts, heavy rain reducing visibility and traffic moving along wet roads on National Route 58. The Trello source material said gusts had exceeded 30 metres per second in Naha, with airport closures, power outages and alerts for flooding and landslides across the region.

A second Reuters video source from Okinawa described winds exceeding 40 metres per second and showed a large tree uprooted near Koza Music Town as rain and debris affected the roadside. The same source said Jangmi was tracking away from the region toward mainland Japan, while authorities continued to warn of lingering rain bands and strong winds.

Transport faces disruption

Severe Tropical Storm Jangmi led to the cancellation of at least 326 flights as of 4 a.m. on Tuesday, mostly to and from the Kyushu region, NHK reported. Japan Airlines cancelled 170 flights scheduled to depart from or arrive at Kagoshima, Miyazaki and Takamatsu airports.

All Nippon Airways cancelled 67 flights, including all services to and from Kagoshima and Miyazaki airports, while other carriers also cancelled routes affected by the storm. Airlines urged passengers to check their websites because additional cancellations and delays could depend on Jangmi's path.

Japan Railway companies said the storm could disrupt Shinkansen bullet train services from Tuesday night. Cancellations and delays were possible on the Tokaido Shinkansen from Tuesday night through Wednesday, while Sanyo and Kyushu Shinkansen services were scheduled to operate as usual but could still be affected.
