Japanese Archipelago Hit by Two Successive Tropical Storms

The Izu archipelago have endured another powerful blow as Typhoon Nakri moved across the region on Monday, coming just after Typhoon Halong, which struck seven days prior.

Immediate Impact on Hachijojima Island

Officials on Hachijojima Island noted interruptions and destruction to about 220 homes after the storm brought 37mm (1.5in) of rain in one hour and wind bursts reaching 95mph. Airport operations were disrupted, public facilities harmed, and intense rains caused ground slides across the group of islands. The storm 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

The storm has since shifted 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. Riding the jet stream, its remnants are on track to reach British Columbia, Canada, delivering intense precipitation, powerful gusts, and coastal flooding.

Recalling Halong's Fury

A week earlier, Halong had unleashed over 200mm of precipitation within three hours, as peak wind speeds hit 122mph. By late morning last Thursday, precipitation levels climbed to 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.

Alaska's Severe Damage

The seaside communities Kipnuk and Kwigillingok were the hardest hit. 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 evacuate displaced residents. Halong remains among the strongest cyclones the area has ever seen. Its rapid intensification was fuelled by unusually warm north Pacific waters, which supplied additional warmth and humidity.

Double Trouble in Mexico

Meanwhile, the nation endured a double blow last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond combined, 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, 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 remain missing. Search and relief efforts persist, with standing water causing health worries in isolated areas.
