Japanese Archipelago Hit by Two Successive Typhoons

The Izu Islands have endured another powerful blow as Typhoon Nakri moved across the area on Monday, coming just after storm Halong, which hit seven days prior.

Immediate Impact on the Island of Hachijojima

Local authorities on Hachijojima noted interruptions and destruction to approximately 220 residences after the typhoon brought an hour of rainfall totaling 37mm and gusts of up to 95mph (152km/h). Flight services were interrupted, infrastructure damaged, and heavy rainfall triggered landslides across the island chain. The storm also generated 9-metre waves, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, 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 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.

Remembering Halong's Impact

Seven days before, 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, shattering the 24-hour record. The storm's leftovers then crossed the north Pacific and reached Alaska on Sunday, bringing a record-breaking 2-metre storm surge.

Alaska's Severe Damage

The coastal villages of Kipnuk and Kwigillingok were the hardest hit. One person died, houses were ruined, and nearly 1,500 people had to evacuate to safe zones. The state underwent one of the largest airlifts in its history to relocate affected individuals. Halong remains one of the most powerful storms the area has ever seen. Its quick strengthening was fuelled by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.

Twin Disasters 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 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. As of Wednesday, 66 fatalities were verified and 75 individuals are still unaccounted for. Search and relief efforts persist, with standing water causing health worries in remote zones.
