Japanese Archipelago Struck by Back-to-Back Tropical Storms
The Izu Islands have endured another powerful blow as Typhoon Nakri swept through the area on Monday, coming just after Typhoon Halong, which struck seven days prior.
Immediate Impact on the Island of Hachijojima
Officials on Hachijojima Island noted interruptions and destruction 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, infrastructure damaged, and heavy rainfall triggered landslides across the island chain. The storm also produced waves as high as 9 meters, 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
Nakri has since transitioned into an extratropical cyclone, 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 remaining parts are headed to reach British Columbia, Canada, delivering intense precipitation, powerful gusts, and coastal flooding.
Recalling Halong's Fury
Seven days before, Halong had unleashed over 200mm of precipitation within three hours, as maximum sustained winds reached 122mph. By the late morning of the previous Thursday, precipitation levels climbed to 349mm, breaking the daily rainfall record. The typhoon’s remnants then crossed the north Pacific and reached Alaska on Sunday, bringing a record-breaking 2-metre storm surge.
Significant Harm in Alaska
The coastal villages of Kipnuk and Kwigillingok were the most affected. One person died, homes were destroyed, and about 1,500 residents were forced into shelters. The state underwent 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 rapid intensification was fuelled by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.
Twin Disasters in Mexico
At the same time, the country endured a double blow last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond combined, 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 initial heavy rains from Priscilla left the ground saturated, 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 isolated areas.
