Japanese Archipelago Struck by Back-to-Back Tropical Storms
The Izu archipelago have endured another powerful blow as Typhoon Nakri swept through the region on Monday, coming just after storm Halong, which struck a week earlier.
Initial Consequences on Hachijojima Island
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 gusts of up to 95mph (152km/h). Flight services were interrupted, public facilities harmed, and intense rains caused ground slides across the group of islands. The typhoon also generated 9-metre waves, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, 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 non-tropical storm system, weakening as it moved eastwards over chilled northern Pacific seas, with wind speeds dropping to about 65mph as of Thursday. Moving along the air current, its remaining parts are headed to reach the Canadian province of British Columbia, bringing heavy rain, strong winds and storm surges.
Remembering Halong's Impact
A week earlier, Halong discharged more than 200mm of rain in three hours, as peak wind speeds hit 122mph. By the late morning of the previous Thursday, rainfall totals reached 349mm, breaking the daily rainfall record. The typhoon’s remnants then crossed the north 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 most affected. One person died, houses were ruined, 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 among the strongest cyclones the area has ever seen. Its rapid intensification was driven 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 remnants of Hurricane Priscilla and Tropical Storm Raymond converged, dumping about 609mm of rain in 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. As of Wednesday, 66 fatalities were verified and 75 remain missing. Rescue and recovery operations are continuing, with standing water causing health worries in remote zones.
