Japanese Islands Struck by Back-to-Back Typhoons

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

Immediate Impact on Hachijojima Island

Local authorities on Hachijojima reported disruption and damage to approximately 220 residences after the storm brought an hour of rainfall totaling 37mm and gusts of up to 95mph (152km/h). Flight services were interrupted, public facilities harmed, and intense rains caused ground slides across the island chain. The storm 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.

Nakri's Transformation

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 remnants are on track to reach British Columbia, Canada, delivering intense precipitation, powerful gusts, and coastal flooding.

Remembering Halong's Impact

A week earlier, Halong discharged over 200mm of precipitation within three hours, as peak wind speeds hit 122mph. By the late morning of the previous Thursday, precipitation levels climbed to 349mm, shattering the 24-hour record. The storm's leftovers then crossed the north 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 most affected. One person died, houses were ruined, and nearly 1,500 people had to evacuate to safe zones. Alaska experienced an historic mass evacuation by air to evacuate displaced residents. Halong stands as among the strongest cyclones the region has experienced. Its rapid intensification was fuelled 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. Steered by a dip in the jet stream, the two weather events struck the same zone one after another. The first deluge from Priscilla left the ground saturated, intensifying flooding when Raymond arrived. Over 300 localities 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 stagnant floodwaters raising health concerns in isolated areas.
