Japanese Archipelago Struck by Back-to-Back Tropical Storms

The Izu archipelago have endured another powerful blow as Typhoon Nakri swept through the area on Monday, coming just after storm Halong, which struck a week earlier.

Immediate Impact 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). Airport operations were disrupted, public facilities harmed, and heavy rainfall triggered landslides across the group of islands. The typhoon also produced waves as high as 9 meters, leading to hazardous shoreline situations. Near Oiso on the Pacific side, 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. Riding the jet stream, 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

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, 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.

Alaska's Severe Damage

The seaside communities Kipnuk and Kwigillingok were the most affected. One person died, homes were destroyed, and about 1,500 residents were forced into shelters. Alaska experienced one of the largest airlifts in its history to evacuate displaced residents. Halong remains one of the most powerful storms the region has experienced. Its quick strengthening was driven by unusually warm north Pacific waters, which provided extra heat and moisture.

Twin Disasters in Mexico

Meanwhile, the country endured a double blow last week as the leftovers of Priscilla and Raymond combined, 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 first deluge from Priscilla made the soil waterlogged, worsening floods as Raymond approached. Over 300 localities were impacted by mudslides and river overflows. As of Wednesday, 66 people have been confirmed dead and 75 remain missing. Rescue and recovery operations are continuing, with standing water causing health worries in remote zones.
