Japanese Archipelago Struck by Back-to-Back Typhoons

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

Initial Consequences on the Island of Hachijojima

Officials on Hachijojima Island noted interruptions and destruction to approximately 220 residences after the typhoon brought 37mm (1.5in) of rain in one hour and wind bursts reaching 95mph. 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 men were swept away while fishing, with one fatality reported.

Nakri's Transformation

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 British Columbia, Canada, delivering intense precipitation, powerful gusts, and coastal flooding.

Recalling Halong's Fury

A week earlier, Halong had unleashed over 200mm of precipitation within three hours, as maximum sustained winds reached 122mph. By the late morning of the previous Thursday, rainfall totals reached 349mm, shattering the 24-hour 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 nearly 1,500 people had to evacuate to safe zones. The state underwent an historic mass evacuation by air to evacuate displaced residents. Halong remains among the strongest cyclones the region has experienced. Its rapid intensification was driven by unusually warm north Pacific waters, which supplied additional warmth and humidity.

Double Trouble in Mexico

Meanwhile, the nation endured a double blow last week as the remnants of Hurricane Priscilla and Tropical Storm 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 left the ground saturated, worsening floods as Raymond approached. More than 300 communities were affected by landslides and overflowing rivers. By Wednesday, 66 people have been confirmed dead and 75 individuals are still unaccounted for. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in remote zones.
