Japanese Archipelago Hit by Back-to-Back Tropical Storms

The Izu archipelago have faced yet another severe impact as tropical cyclone Nakri swept through the area on Monday, following in the footsteps of Typhoon Halong, which struck seven days prior.

Initial Consequences on the Island of Hachijojima

Local authorities on Hachijojima reported disruption and damage to approximately 220 residences after the typhoon brought 37mm (1.5in) of rain in one hour and gusts of up to 95mph (152km/h). Flight services were interrupted, infrastructure damaged, and intense rains caused ground slides across the group of islands. The storm 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.

Nakri's Transformation

The storm has since shifted into an extratropical cyclone, weakening as it moved eastwards over cooler north Pacific waters, with gusts reducing to around 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.

Remembering Halong's Impact

Seven days before, 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, shattering the 24-hour 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 coastal villages of Kipnuk and Kwigillingok were the most affected. A single fatality occurred, homes were destroyed, and about 1,500 residents were forced into shelters. Alaska experienced an historic mass evacuation by air to relocate affected individuals. Halong remains one of the most powerful storms the area has ever seen. Its quick strengthening was driven by unusually warm north Pacific waters, which provided extra heat and moisture.

Double Trouble in Mexico

Meanwhile, the country 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 central and eastern regions. 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 fatalities were verified and 75 remain missing. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in remote zones.
