Japan's Islands Struck by Back-to-Back Tropical Storms
The Izu Islands have faced yet another severe impact as tropical cyclone Nakri moved across the area on Monday, following in the footsteps of Typhoon Halong, which struck seven days prior.
Immediate Impact 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, public facilities harmed, and heavy rainfall triggered landslides across the group of islands. The storm also produced waves as high as 9 meters, creating dangerous coastal conditions. Off the Pacific coast in Oiso, in Kanagawa prefecture, three fishermen were carried off by waves, 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. 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
Seven days before, Halong discharged 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 reached Alaska on Sunday, causing an unprecedented 2-meter coastal surge.
Significant Harm in Alaska
The seaside communities Kipnuk and Kwigillingok were the most affected. A single fatality occurred, houses were ruined, and about 1,500 residents were forced into shelters. Alaska experienced one of the largest airlifts in its history to evacuate displaced residents. Halong remains one of the most powerful storms the area has ever seen. Its quick strengthening was fuelled by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.
Double Trouble in Mexico
At the same time, the country endured a double blow last week as the leftovers of Priscilla and Raymond combined, releasing nearly 609mm of precipitation over 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. As of Wednesday, 66 fatalities were verified and 75 remain missing. Search and relief efforts persist, with standing water causing health worries in remote zones.
