The Izu archipelago have faced yet another severe impact as Typhoon Nakri swept through the area on Monday, coming just after Typhoon Halong, which struck a week earlier.

Initial Consequences on Hachijojima Island

Local authorities on Hachijojima reported disruption and damage to approximately 220 residences after the typhoon brought 37mm (1.5in) of rain in one hour and gusts of up to 95mph (152km/h). Flight services were interrupted, infrastructure damaged, 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 the Kanagawa region, three fishermen were carried off by waves, 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 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, bringing heavy rain, strong winds and storm surges.

Remembering Halong's Impact

A week earlier, 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, precipitation levels climbed to 349mm, breaking the daily rainfall 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 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 remains one of the most powerful storms the region has experienced. Its rapid intensification was fuelled by abnormally hot northern Pacific seas, 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 converged, releasing nearly 609mm of precipitation over four days across central and eastern regions. Guided by a trough in the air current, the two weather events struck the same zone one after another. The initial heavy rains from Priscilla made the soil waterlogged, worsening floods as Raymond approached. Over 300 localities were impacted by mudslides and river overflows. As of Wednesday, 66 fatalities were verified and 75 individuals are still unaccounted for. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in isolated areas.
