Japan's Islands Hit by Two Successive Tropical Storms

The Izu archipelago have endured another powerful blow as tropical cyclone Nakri swept through the area on Monday, coming just after Typhoon Halong, which hit seven days prior.

Immediate Impact on the Island of Hachijojima

Officials on Hachijojima Island reported disruption and damage to about 220 homes after the storm 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, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, in Kanagawa prefecture, three men were swept away while fishing, with one fatality reported.

The Evolution of Nakri

Nakri has since transitioned 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

A week earlier, Halong had unleashed more than 200mm of rain in three hours, as peak wind speeds hit 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 nearly 1,500 people had to evacuate to safe zones. Alaska experienced an historic mass evacuation by air to relocate affected individuals. Halong remains among the strongest cyclones the area has ever seen. Its rapid intensification was driven by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.

Double Trouble in Mexico

At the same time, the country faced two consecutive hits last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond converged, releasing nearly 609mm of precipitation over four days across the central and eastern areas. Guided by a trough in the air current, both systems hit the same area in quick succession. The initial heavy rains from Priscilla left the ground saturated, worsening floods as Raymond approached. 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 standing water causing health worries in remote zones.
