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 region on Monday, coming just after storm Halong, which struck seven days prior.

Immediate Impact on Hachijojima Island

Officials on Hachijojima Island noted interruptions and destruction to about 220 homes after the typhoon brought 37mm (1.5in) of rain in one hour and gusts of up to 95mph (152km/h). Flight services were interrupted, public facilities harmed, and intense rains caused ground slides across the island chain. The typhoon also produced waves as high as 9 meters, leading to hazardous shoreline situations. 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 non-tropical storm system, 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

Seven days before, Halong had unleashed over 200mm of precipitation within three hours, as peak wind speeds hit 122mph. By late morning last Thursday, rainfall totals reached 349mm, shattering the 24-hour record. The storm's leftovers then traveled over the northern 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. One person died, homes were destroyed, and nearly 1,500 people had to evacuate to safe zones. The state underwent one of the largest airlifts in its history to relocate affected individuals. Halong remains among the strongest cyclones 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 remnants of Hurricane Priscilla and Tropical Storm Raymond converged, dumping about 609mm of rain in four days across central and eastern regions. Guided by a trough in the air current, the two weather events struck the same zone one after another. The first deluge from Priscilla made the soil waterlogged, worsening floods as Raymond approached. Over 300 localities were affected by landslides and overflowing rivers. By Wednesday, 66 people have been confirmed dead and 75 individuals are still unaccounted for. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in remote zones.
