Japanese Archipelago Struck by Back-to-Back Tropical Storms
The Izu Islands have faced yet another severe impact as tropical cyclone Nakri swept through the region on Monday, following in the footsteps of storm Halong, which struck seven days prior.
Initial Consequences on Hachijojima Island
Local authorities on Hachijojima noted interruptions and destruction to about 220 homes after the storm brought 37mm (1.5in) of rain in one hour 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 typhoon also generated 9-metre waves, creating dangerous coastal conditions. Near Oiso on the Pacific side, in Kanagawa prefecture, three fishermen were carried off by waves, with one fatality reported.
The Evolution of Nakri
The storm has since shifted 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 remaining parts are headed to reach British Columbia, Canada, delivering intense precipitation, powerful gusts, and coastal flooding.
Remembering Halong's Impact
A week earlier, Halong discharged more than 200mm of rain in 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 traveled over the northern Pacific and arrived in Alaska on Sunday, causing an unprecedented 2-meter coastal surge.
Alaska's Severe Damage
The seaside communities Kipnuk and Kwigillingok were the most affected. A single fatality occurred, houses were ruined, and nearly 1,500 people had to evacuate to safe zones. Alaska experienced one of the largest airlifts in its history to evacuate displaced residents. Halong remains one of the most powerful storms the region has experienced. Its quick strengthening was driven by unusually warm north Pacific waters, which supplied additional warmth and humidity.
Double Trouble in Mexico
At the same time, the nation faced two consecutive hits last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond converged, releasing nearly 609mm of precipitation over four days across central and eastern regions. 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, worsening floods as Raymond approached. More than 300 communities were impacted by mudslides and river overflows. As of Wednesday, 66 people have been confirmed dead and 75 remain missing. Rescue and recovery operations are continuing, with standing water causing health worries in remote zones.
