Japanese Archipelago Struck by Two Successive Typhoons

The Izu Islands have faced yet another severe impact as Typhoon Nakri moved across the area on Monday, coming just after storm Halong, which hit seven days prior.

Immediate Impact on the Island of Hachijojima

Local authorities on Hachijojima 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). Flight services were interrupted, infrastructure damaged, and heavy rainfall triggered landslides across the group of islands. The typhoon also generated 9-metre waves, leading to hazardous shoreline situations. Near Oiso on the Pacific side, in Kanagawa prefecture, three men were swept away while fishing, with one fatality reported.

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.

Recalling Halong's Fury

A week earlier, Halong had unleashed more than 200mm of rain in three hours, as maximum sustained winds reached 122mph. By late morning last Thursday, precipitation levels climbed to 349mm, breaking the daily rainfall record. The storm's leftovers then crossed the north Pacific and reached Alaska on Sunday, causing an unprecedented 2-meter coastal 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 one of the most powerful storms the region has experienced. Its quick strengthening was fuelled by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.

Double Trouble in Mexico

Meanwhile, the country faced two consecutive hits last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond combined, dumping about 609mm of rain in 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 left the ground saturated, intensifying flooding when Raymond arrived. Over 300 localities were affected by landslides and overflowing rivers. As of Wednesday, 66 fatalities were verified and 75 remain missing. Rescue and recovery operations are continuing, with standing water causing health worries in remote zones.
