Japanese Archipelago Hit by Back-to-Back Tropical Storms

The Izu Islands have faced yet another severe impact as Typhoon Nakri swept through the region on Monday, following in the footsteps of storm Halong, which struck seven days prior.

Initial Consequences on Hachijojima Island

Local authorities on Hachijojima noted interruptions and destruction to approximately 220 residences after the typhoon brought an hour of rainfall totaling 37mm and gusts of up to 95mph (152km/h). Airport operations were disrupted, public facilities harmed, and heavy rainfall triggered landslides across the group of islands. The storm also generated 9-metre waves, creating dangerous coastal conditions. Near Oiso on the Pacific side, in the Kanagawa region, three men were swept away while fishing, one of whom has been confirmed dead.

The Evolution of Nakri

The storm has since shifted into an non-tropical storm system, losing strength while traveling east over cooler north Pacific waters, with gusts reducing to around 65mph as of Thursday. Moving along the air current, its remaining parts are headed to reach the Canadian province of British Columbia, bringing heavy rain, strong winds and storm surges.

Recalling Halong's Fury

Seven days before, Halong discharged over 200mm of precipitation within 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 traveled over the northern Pacific and arrived in Alaska on Sunday, causing an unprecedented 2-meter coastal surge.

Significant Harm in Alaska

The coastal villages of Kipnuk and Kwigillingok were the hardest hit. A single fatality occurred, houses were ruined, and about 1,500 residents were forced into shelters. Alaska experienced an historic mass evacuation by air to evacuate displaced residents. Halong stands as among the strongest cyclones the area has ever seen. Its rapid intensification was driven by abnormally hot northern Pacific seas, which provided extra heat and moisture.

Double Trouble in Mexico

At the same time, the nation endured a double blow last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond converged, releasing nearly 609mm of precipitation over four days across central and eastern regions. Steered by a dip in the jet stream, both systems hit the same area in quick succession. The initial heavy rains from Priscilla left the ground saturated, intensifying flooding when Raymond arrived. More than 300 communities were affected by landslides and overflowing rivers. By Wednesday, 66 fatalities were verified and 75 individuals are still unaccounted for. Rescue and recovery operations are continuing, with standing water causing health worries in isolated areas.
