Japanese Islands Struck by Back-to-Back Tropical Storms

The Izu Islands have endured another powerful blow as Typhoon Nakri swept through the region on Monday, coming just after Typhoon Halong, which hit seven days prior.

Initial Consequences on the Island of Hachijojima

Local authorities on Hachijojima reported disruption and damage to approximately 220 residences after the typhoon brought 37mm (1.5in) of rain in one hour and gusts of up to 95mph (152km/h). Flight services were interrupted, public facilities harmed, and intense rains caused ground slides across the group of islands. The storm also generated 9-metre waves, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, in Kanagawa prefecture, three men were swept away while fishing, with one fatality reported.

The Evolution of Nakri

The storm has since shifted into an extratropical cyclone, losing strength while traveling east over chilled northern Pacific seas, with gusts reducing to around 65mph as of Thursday. Moving along the air current, its remnants are on track to reach British Columbia, Canada, bringing heavy rain, strong winds and storm surges.

Remembering Halong's Impact

Seven days before, Halong had unleashed more than 200mm of rain in three hours, as maximum sustained winds reached 122mph. By the late morning of the previous Thursday, precipitation levels climbed to 349mm, shattering the 24-hour record. The typhoon’s remnants then crossed the north Pacific and reached Alaska on Sunday, causing an unprecedented 2-meter coastal surge.

Alaska's Severe Damage

The coastal villages of Kipnuk and Kwigillingok were the most affected. One person died, houses were ruined, and about 1,500 residents were forced into shelters. The state underwent an historic mass evacuation by air to relocate affected individuals. Halong stands as among the strongest cyclones the area has ever seen. Its rapid intensification was fuelled by unusually warm north Pacific waters, which supplied additional warmth and humidity.

Double Trouble in Mexico

Meanwhile, the nation endured a double blow last week as the leftovers of Priscilla and Raymond converged, releasing nearly 609mm of precipitation over four days across central and eastern regions. Guided by a trough in the air current, both systems hit the same area in quick succession. The initial heavy rains from Priscilla made the soil waterlogged, intensifying flooding when Raymond arrived. Over 300 localities were affected by landslides and overflowing rivers. By Wednesday, 66 people have been confirmed dead and 75 remain missing. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in isolated areas.
