Japanese Archipelago Struck by Two Successive Typhoons

The Izu archipelago have endured another powerful blow as Typhoon Nakri swept through the region on Monday, following in the footsteps of Typhoon Halong, which struck a week earlier.

Immediate Impact on the Island of Hachijojima

Officials on Hachijojima Island noted interruptions and destruction to about 220 homes after the storm 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 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, one of whom has been confirmed dead.

The Evolution of Nakri

Nakri has since transitioned into an non-tropical storm system, weakening as it moved eastwards over chilled northern Pacific seas, with wind speeds dropping to about 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

A week earlier, Halong discharged 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, breaking the daily rainfall record. The storm's leftovers then crossed the north Pacific and arrived in Alaska on Sunday, causing an unprecedented 2-meter coastal surge.

Significant Harm in Alaska

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 fuelled by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.

Twin Disasters in Mexico

Meanwhile, the nation endured a double blow last week as the leftovers of Priscilla and Raymond converged, dumping about 609mm of rain in four days across central and eastern regions. Steered by a dip in the jet stream, the two weather events struck the same zone one after another. The initial heavy rains 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 remain missing. Rescue and recovery operations are continuing, with standing water causing health worries in remote zones.
