Japan's Islands Hit by Two Successive Tropical Storms

The Izu archipelago have endured another powerful blow as tropical cyclone Nakri swept through the region on Monday, coming just after storm Halong, which struck a week earlier.

Immediate Impact on Hachijojima Island

Local authorities on Hachijojima noted interruptions and destruction to approximately 220 residences after the typhoon brought 37mm (1.5in) of rain in one hour and wind bursts reaching 95mph. Flight services were interrupted, infrastructure damaged, 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 men were swept away while fishing, one of whom has been confirmed dead.

Nakri's Transformation

Nakri has since transitioned into an extratropical cyclone, 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 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 peak wind speeds hit 122mph. By the late morning of the previous Thursday, precipitation levels climbed to 349mm, breaking the daily rainfall record. The storm's leftovers then crossed the north 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. Alaska experienced one of the largest airlifts in its history to relocate affected individuals. Halong remains one of the most powerful storms the area has ever seen. Its quick strengthening was driven by abnormally hot northern Pacific seas, which provided extra heat and moisture.

Double Trouble in Mexico

Meanwhile, the nation faced two consecutive hits last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond combined, 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 first deluge from Priscilla made the soil waterlogged, worsening floods as Raymond approached. Over 300 localities were affected by landslides and overflowing rivers. As of 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.
