Japanese Archipelago Hit by Two Successive Tropical Storms

The Izu archipelago have faced yet another severe impact as tropical cyclone Nakri moved across the region on Monday, following in the footsteps of storm Halong, which hit seven days prior.

Initial Consequences on Hachijojima Island

Officials on Hachijojima Island reported disruption and damage to about 220 homes 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, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, in the Kanagawa region, three fishermen were carried off by waves, one of whom has been confirmed dead.

The Evolution of Nakri

Nakri has since transitioned 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 remaining parts are headed to reach the Canadian province of British Columbia, delivering intense precipitation, powerful gusts, and coastal flooding.

Remembering Halong's Impact

A week earlier, Halong had unleashed more than 200mm of rain in three hours, as peak wind speeds hit 122mph. By late morning last Thursday, precipitation levels climbed to 349mm, breaking the daily rainfall record. The typhoon’s remnants then traveled over the northern Pacific and reached 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. One person died, homes were destroyed, and about 1,500 residents were forced into shelters. Alaska experienced 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 country faced two consecutive hits last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond converged, dumping about 609mm of rain in four days across the central and eastern areas. 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, 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. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in remote zones.
