Japanese Archipelago Struck by Back-to-Back Typhoons

The Izu Islands have faced yet another severe impact as tropical cyclone Nakri swept through the region on Monday, coming just after storm Halong, which struck seven days prior.

Immediate Impact on Hachijojima Island

Local authorities on Hachijojima reported disruption and damage to about 220 homes after the typhoon brought 37mm (1.5in) of rain in one hour and gusts of up to 95mph (152km/h). Flight services were interrupted, infrastructure damaged, and intense rains caused ground slides across the island chain. The storm also generated 9-metre waves, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, in Kanagawa prefecture, three fishermen were carried off by waves, with one fatality reported.

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 wind speeds dropping to about 65mph as of Thursday. Moving along the air current, its remnants are on track to reach the Canadian province of British Columbia, bringing heavy rain, strong winds and storm surges.

Recalling Halong's Fury

A week earlier, Halong had unleashed over 200mm of precipitation within three hours, as peak wind speeds hit 122mph. By the late morning of the previous Thursday, rainfall totals reached 349mm, breaking the daily rainfall record. The storm's leftovers then traveled over the northern Pacific and arrived in Alaska on Sunday, bringing a record-breaking 2-metre storm surge.

Significant Harm in Alaska

The coastal villages of Kipnuk and Kwigillingok were the most affected. A single fatality occurred, houses were ruined, and nearly 1,500 people had to evacuate to safe zones. The state underwent an historic mass evacuation by air to relocate affected individuals. Halong remains among the strongest cyclones the region has experienced. Its rapid intensification was driven by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.

Double Trouble in Mexico

At the same time, 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. Steered by a dip in the jet stream, the two weather events struck the same zone one after another. The initial heavy rains from Priscilla left the ground saturated, worsening floods as Raymond approached. Over 300 localities were impacted by mudslides and river overflows. By Wednesday, 66 fatalities were verified and 75 individuals are still unaccounted for. Search and relief efforts persist, with standing water causing health worries in remote zones.
