Japanese Archipelago Hit by Two Successive Tropical Storms
The Izu Islands have faced yet another severe impact as tropical cyclone Nakri moved across the region on Monday, following in the footsteps of storm Halong, which struck seven days prior.
Initial Consequences on Hachijojima Island
Local authorities on Hachijojima noted interruptions and destruction to about 220 homes after the storm brought an hour of rainfall totaling 37mm and wind bursts reaching 95mph. Flight services were interrupted, public facilities harmed, and heavy rainfall triggered landslides across the group of islands. The storm also generated 9-metre waves, creating dangerous coastal conditions. Near Oiso on the Pacific side, in Kanagawa prefecture, three men were swept away while fishing, with one fatality reported.
The Evolution of Nakri
The storm has since shifted into an non-tropical storm system, weakening as it moved eastwards over chilled northern Pacific seas, with gusts reducing to around 65mph as of Thursday. Moving along the air current, its remnants are on track to reach the Canadian province of British Columbia, delivering intense precipitation, powerful gusts, and coastal flooding.
Recalling Halong's Fury
A week earlier, 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 storm's leftovers then crossed the north Pacific and reached Alaska on Sunday, bringing a record-breaking 2-metre storm surge.
Significant Harm in Alaska
The seaside communities Kipnuk and Kwigillingok were the hardest hit. A single fatality occurred, 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 stands as among the strongest cyclones the area has ever seen. Its quick strengthening was fuelled by unusually warm north Pacific waters, which provided extra heat and moisture.
Twin Disasters in Mexico
Meanwhile, the country endured a double blow last week as the leftovers of Priscilla and Raymond combined, releasing nearly 609mm of precipitation over four days across central and eastern regions. Steered by a dip in the jet stream, both systems hit the same area in quick succession. The first deluge from Priscilla left the ground saturated, worsening floods as Raymond approached. More than 300 communities were impacted by mudslides and river overflows. As of Wednesday, 66 fatalities were verified and 75 remain missing. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in remote zones.
