Japanese Archipelago Hit by Back-to-Back Tropical Storms
The Izu archipelago have endured another powerful blow as Typhoon Nakri swept through the area on Monday, following in the footsteps of storm Halong, which hit seven days prior.
Immediate Impact on Hachijojima Island
Officials on Hachijojima Island reported disruption and damage to approximately 220 residences after the storm brought an hour of rainfall totaling 37mm and gusts of up to 95mph (152km/h). Flight services were interrupted, public facilities harmed, and heavy rainfall triggered landslides across the island chain. The typhoon also generated 9-metre waves, creating dangerous coastal conditions. Off the Pacific coast in Oiso, in Kanagawa prefecture, three men were swept away while fishing, one of whom has been confirmed dead.
The Evolution of Nakri
Nakri has since transitioned into an non-tropical storm system, losing strength while traveling east over cooler north Pacific waters, with gusts reducing to around 65mph as of Thursday. Riding the jet stream, its remaining parts are headed to reach the Canadian province of British Columbia, delivering intense precipitation, powerful gusts, and coastal flooding.
Remembering Halong's Impact
A week earlier, Halong had unleashed more than 200mm of rain in three hours, as maximum sustained winds reached 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 arrived in Alaska on Sunday, bringing a record-breaking 2-metre storm surge.
Alaska's Severe Damage
The seaside communities Kipnuk and Kwigillingok were the most affected. A single fatality occurred, houses were ruined, and nearly 1,500 people had to evacuate to safe zones. Alaska experienced one of the largest airlifts in its history to relocate affected individuals. Halong stands as among the strongest cyclones the region has experienced. Its rapid intensification was fuelled by unusually warm north Pacific waters, which supplied additional warmth and humidity.
Twin Disasters in Mexico
At the same time, the country endured a double blow last week as the leftovers of Priscilla and Raymond converged, 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 initial heavy rains from Priscilla made the soil waterlogged, intensifying flooding when Raymond arrived. More than 300 communities were affected by landslides and overflowing rivers. By Wednesday, 66 people have been confirmed dead and 75 remain missing. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in remote zones.
