Japanese Archipelago Hit by Two Successive Typhoons

The Izu archipelago have faced yet another severe impact as tropical cyclone Nakri moved across the area on Monday, following in the footsteps of storm Halong, which hit a week earlier.

Initial Consequences on the Island of Hachijojima

Local authorities on Hachijojima reported disruption and damage to approximately 220 residences after the storm brought an hour of rainfall totaling 37mm 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. Near Oiso on the Pacific side, in Kanagawa prefecture, three fishermen were carried off by waves, 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 remaining parts are headed to reach British Columbia, Canada, 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 peak wind speeds hit 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 arrived in Alaska on Sunday, bringing a record-breaking 2-metre storm surge.

Significant Harm in Alaska

The seaside communities Kipnuk and Kwigillingok were the most affected. One person died, homes were destroyed, and about 1,500 residents were forced into shelters. The state underwent one of the largest airlifts in its history to relocate affected individuals. Halong stands as among the strongest cyclones the region has experienced. Its rapid intensification was driven by abnormally hot northern Pacific seas, which provided extra heat and moisture.

Twin Disasters in Mexico

Meanwhile, the nation faced two consecutive hits last week as the leftovers of Priscilla and Raymond combined, releasing nearly 609mm of precipitation over four days across the central and eastern areas. Guided by a trough in the air current, the two weather events struck the same zone one after another. The first deluge from Priscilla left the ground saturated, intensifying flooding when Raymond arrived. Over 300 localities were impacted by mudslides and river overflows. By Wednesday, 66 people have been confirmed dead and 75 individuals are still unaccounted for. Search and relief efforts persist, with stagnant floodwaters raising health concerns in remote zones.
