The Izu archipelago have endured another powerful blow as tropical cyclone Nakri moved across the region on Monday, coming just after Typhoon Halong, which struck seven days prior.

Immediate Impact on Hachijojima Island

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, public facilities harmed, and heavy rainfall triggered landslides across the island chain. The typhoon also produced waves as high as 9 meters, creating dangerous coastal conditions. Off the Pacific coast in Oiso, in Kanagawa prefecture, three fishermen were carried off by waves, one of whom has been confirmed dead.

Nakri's Transformation

The storm has since shifted 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 remaining parts are headed 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 more than 200mm of rain in 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 reached Alaska on Sunday, causing an unprecedented 2-meter coastal surge.

Alaska's Severe Damage

The seaside communities Kipnuk and Kwigillingok were the hardest hit. A single fatality occurred, homes were destroyed, and nearly 1,500 people had to evacuate to safe zones. Alaska experienced one of the largest airlifts in its history to relocate affected individuals. Halong remains among the strongest cyclones the area has ever seen. Its rapid intensification was fuelled by unusually warm north Pacific waters, which supplied additional warmth and humidity.

Double Trouble in Mexico

At the same time, the nation endured a double blow last week as the leftovers of Priscilla and Raymond combined, releasing nearly 609mm of precipitation over four days across the central and eastern areas. 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, worsening floods as Raymond approached. More than 300 communities were impacted by mudslides and river overflows. By Wednesday, 66 people have been confirmed dead and 75 individuals are still unaccounted for. Rescue and recovery operations are continuing, with standing water causing health worries in remote zones.
