Japanese Archipelago Struck by Back-to-Back Tropical Storms

The Izu Islands have faced yet another severe impact as Typhoon Nakri swept through the area on Monday, following in the footsteps of Typhoon Halong, which struck a week earlier.

Immediate Impact on the Island of Hachijojima

Local authorities on Hachijojima noted interruptions and destruction to about 220 homes after the typhoon brought an hour of rainfall totaling 37mm and gusts of up to 95mph (152km/h). Flight services were interrupted, infrastructure damaged, and intense rains caused ground slides across the island chain. The storm also generated 9-metre waves, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, in Kanagawa prefecture, three fishermen were carried off by waves, with one fatality reported.

Nakri's Transformation

Nakri has since transitioned into an non-tropical storm system, losing strength while traveling east over chilled northern Pacific seas, with gusts reducing to around 65mph as of Thursday. Riding the jet stream, its remnants are on track to reach British Columbia, Canada, bringing heavy rain, strong winds and storm surges.

Remembering Halong's Impact

Seven days before, Halong discharged more than 200mm of rain in three hours, as maximum sustained winds reached 122mph. By late morning last Thursday, rainfall totals reached 349mm, breaking the daily rainfall record. The storm's leftovers then traveled over the northern 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. A single fatality occurred, 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 remains among the strongest cyclones the region has experienced. Its quick strengthening was driven by unusually warm north Pacific waters, which supplied additional warmth and humidity.

Double Trouble 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 central and eastern regions. Guided by a trough in the air current, both systems hit the same area in quick succession. The initial heavy rains from Priscilla made the soil waterlogged, worsening floods as Raymond approached. Over 300 localities were impacted by mudslides and river overflows. As of Wednesday, 66 fatalities were verified and 75 individuals are still unaccounted for. Search and relief efforts persist, with stagnant floodwaters raising health concerns in isolated areas.
