Japanese Archipelago Hit by Back-to-Back Typhoons
The Izu Islands have faced yet another severe impact as tropical cyclone Nakri moved across the area on Monday, coming just after storm Halong, which hit seven days prior.
Initial Consequences on the Island of Hachijojima
Officials on Hachijojima Island reported disruption and damage 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 island chain. The typhoon also generated 9-metre waves, leading to hazardous shoreline situations. Near Oiso on the Pacific side, in Kanagawa prefecture, three men were swept away while fishing, one of whom has been confirmed dead.
Nakri's Transformation
Nakri has since transitioned into an extratropical cyclone, losing strength while traveling east over cooler north Pacific waters, with gusts reducing to around 65mph as of Thursday. Riding the jet stream, its remnants are on track to reach British Columbia, Canada, delivering intense precipitation, powerful gusts, and coastal flooding.
Remembering Halong's Impact
A week earlier, Halong discharged over 200mm of precipitation within three hours, as peak wind speeds hit 122mph. By late morning last Thursday, rainfall totals reached 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 seaside communities Kipnuk and Kwigillingok were the most affected. A single fatality occurred, homes were destroyed, and about 1,500 residents were forced into shelters. The state underwent one of the largest airlifts in its history to evacuate displaced residents. 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.
Double Trouble in Mexico
At the same time, the country endured a double blow last week as the leftovers of Priscilla and Raymond converged, dumping about 609mm of rain in four days across the central and eastern areas. Guided by a trough in the air current, the two weather events struck the same zone one after another. The initial heavy rains from Priscilla made the soil waterlogged, intensifying flooding when Raymond arrived. Over 300 localities were impacted by mudslides and river overflows. By Wednesday, 66 people have been confirmed dead and 75 remain missing. Search and relief efforts persist, with stagnant floodwaters raising health concerns in remote zones.
