Japanese Islands Struck 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 hit seven days prior.
Initial Consequences on Hachijojima Island
Local authorities on Hachijojima 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). Airport operations were disrupted, infrastructure damaged, and intense rains caused ground slides 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 fishermen were carried off by waves, 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 wind speeds dropping to about 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.
Recalling Halong's Fury
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, rainfall totals reached 349mm, breaking the daily rainfall record. The storm's leftovers then crossed the north Pacific and arrived in 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. One person died, houses were ruined, and nearly 1,500 people had to evacuate to safe zones. The state underwent an historic mass evacuation by air to relocate affected individuals. Halong remains among the strongest cyclones the region has experienced. 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 leftovers of Priscilla and Raymond converged, dumping about 609mm of rain in four days across the central and eastern areas. Steered by a dip in the jet stream, 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. More than 300 communities were affected by landslides and overflowing rivers. As of Wednesday, 66 people have been confirmed dead and 75 remain missing. Search and relief efforts persist, with stagnant floodwaters raising health concerns in isolated areas.
