The Izu archipelago have faced yet another severe impact as tropical cyclone Nakri moved across the area on Monday, coming just after storm Halong, which struck seven days prior.

Immediate Impact on Hachijojima Island

Officials on Hachijojima Island noted interruptions and destruction to about 220 homes after the typhoon brought 37mm (1.5in) of rain in one hour and wind bursts reaching 95mph. Flight services were interrupted, public facilities harmed, and heavy rainfall triggered landslides across the island chain. The typhoon also generated 9-metre waves, creating dangerous coastal conditions. Near Oiso on the Pacific side, in Kanagawa prefecture, three fishermen were carried off by waves, with one fatality reported.

The Evolution of Nakri

The storm has since shifted into an non-tropical storm system, weakening as it moved eastwards over cooler north Pacific waters, 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

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, shattering the 24-hour record. The typhoon’s remnants then traveled over the northern Pacific and reached Alaska on Sunday, causing an unprecedented 2-meter coastal surge.

Significant Harm in Alaska

The seaside communities Kipnuk and Kwigillingok were the hardest hit. One person died, homes were destroyed, and about 1,500 residents were forced into shelters. The state underwent 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 quick strengthening was fuelled by unusually warm north Pacific waters, which supplied additional warmth and humidity.

Double Trouble in Mexico

At the same time, the nation faced two consecutive hits 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, the two weather events struck the same zone one after another. The initial heavy rains from Priscilla left the ground saturated, intensifying flooding when Raymond arrived. More than 300 communities were affected by landslides and overflowing rivers. As of Wednesday, 66 fatalities were verified and 75 remain missing. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in isolated areas.
