Japan's Archipelago Struck by Back-to-Back Tropical Storms
The Izu archipelago have endured another powerful blow as tropical cyclone Nakri moved across the region on Monday, following in the footsteps of Typhoon Halong, which struck a week earlier.
Initial Consequences on Hachijojima Island
Local authorities on Hachijojima 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). Airport operations were disrupted, infrastructure damaged, and heavy rainfall triggered landslides across the group of islands. The typhoon also generated 9-metre waves, leading to hazardous shoreline situations. Near Oiso on the Pacific side, in the Kanagawa region, three men were swept away while fishing, with one fatality reported.
Nakri's Transformation
The storm has since shifted 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. Moving along the air current, its remaining parts are headed to reach British Columbia, Canada, delivering intense precipitation, powerful gusts, and coastal flooding.
Remembering Halong's Impact
Seven days before, Halong discharged over 200mm of precipitation within three hours, as maximum sustained winds reached 122mph. By late morning last 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 nearly 1,500 people had to evacuate to safe zones. The state underwent 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 abnormally hot northern Pacific seas, which provided extra heat and moisture.
Twin Disasters in Mexico
Meanwhile, the country faced two consecutive hits last week as the leftovers of Priscilla and Raymond converged, releasing nearly 609mm of precipitation over four days across the central and eastern areas. Steered by a dip in the jet stream, both systems hit the same area in quick succession. The first deluge from Priscilla made the soil waterlogged, intensifying flooding when Raymond arrived. More than 300 communities were impacted by mudslides and river overflows. By Wednesday, 66 fatalities were verified and 75 remain missing. Search and relief efforts persist, with stagnant floodwaters raising health concerns in remote zones.
