Japanese Islands Hit by Two Successive Typhoons

The Izu Islands have faced yet another severe impact as Typhoon Nakri swept through the region on Monday, following in the footsteps of Typhoon Halong, which struck 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 37mm (1.5in) of rain in one hour and wind bursts reaching 95mph. Flight services were interrupted, infrastructure damaged, and heavy rainfall triggered landslides across the group of islands. The typhoon 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

Nakri has since transitioned into an extratropical cyclone, weakening as it moved eastwards over cooler north Pacific waters, with gusts reducing to around 65mph as of Thursday. Riding the jet stream, its remnants are on track to reach the Canadian province of British Columbia, delivering intense precipitation, powerful gusts, and coastal flooding.

Recalling Halong's Fury

Seven days before, Halong had unleashed 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 reached Alaska on Sunday, causing an unprecedented 2-meter coastal surge.

Alaska's Severe Damage

The coastal villages of Kipnuk and Kwigillingok were the hardest hit. 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 stands as one of the most powerful storms the area has ever seen. Its rapid intensification was driven by unusually warm north Pacific waters, which supplied additional warmth and humidity.

Double Trouble in Mexico

Meanwhile, the country 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, 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 affected by landslides and overflowing rivers. As of Wednesday, 66 fatalities were verified and 75 remain missing. Search and relief efforts persist, with stagnant floodwaters raising health concerns in remote zones.
