Japanese Islands Hit by Back-to-Back Typhoons

The Izu archipelago have faced yet another severe impact as tropical cyclone Nakri moved across the region on Monday, following in the footsteps of Typhoon Halong, which hit a week earlier.

Immediate Impact on Hachijojima Island

Officials on Hachijojima Island 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 produced waves as high as 9 meters, creating dangerous coastal conditions. Off the Pacific coast in Oiso, in the Kanagawa region, three men were swept away while fishing, with one fatality reported.

The Evolution of Nakri

The storm has since shifted into an extratropical cyclone, losing strength while traveling east over chilled northern Pacific seas, with wind speeds dropping to about 65mph as of Thursday. Moving along the air current, 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, precipitation levels climbed to 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. A single fatality occurred, homes were destroyed, and nearly 1,500 people had to evacuate to safe zones. Alaska experienced an historic mass evacuation by air to evacuate displaced residents. Halong stands as one of the most powerful storms the region has experienced. Its rapid intensification was fuelled by unusually warm north Pacific waters, which provided extra heat and moisture.

Double Trouble in Mexico

At the same time, the nation endured a double blow last week as the leftovers of Priscilla and Raymond converged, dumping about 609mm of rain in four days across central and eastern regions. Guided by a trough in the air current, both systems hit the same area in quick succession. The first deluge from Priscilla made the soil waterlogged, intensifying flooding when Raymond arrived. More than 300 communities were impacted by mudslides and river overflows. 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 remote zones.
