Japan's Islands Hit by Back-to-Back Tropical Storms

The Izu archipelago have endured another powerful blow as Typhoon Nakri moved across the region on Monday, following in the footsteps of storm Halong, which hit a week earlier.

Initial Consequences on Hachijojima Island

Officials on Hachijojima Island noted interruptions and destruction to about 220 homes after the typhoon brought an hour of rainfall totaling 37mm and wind bursts reaching 95mph. Airport operations were disrupted, public facilities harmed, and heavy rainfall triggered landslides across the island chain. The typhoon also generated 9-metre waves, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, in Kanagawa prefecture, three men were swept away while fishing, one of whom has been confirmed dead.

The Evolution of Nakri

Nakri has since transitioned into an non-tropical storm system, losing strength while traveling east over cooler north Pacific waters, with wind speeds dropping to about 65mph as of Thursday. Riding the jet stream, its remnants are on track to reach British Columbia, Canada, bringing heavy rain, strong winds and storm surges.

Remembering Halong's Impact

Seven days before, Halong had unleashed over 200mm of precipitation within three hours, as maximum sustained winds reached 122mph. By the late morning of the previous Thursday, rainfall totals reached 349mm, breaking the daily rainfall record. The typhoon’s remnants then traveled over the northern Pacific and arrived in Alaska on Sunday, bringing a record-breaking 2-metre storm surge.

Significant Harm in Alaska

The coastal villages of Kipnuk and Kwigillingok were the hardest hit. One person died, homes were destroyed, and about 1,500 residents were forced into shelters. Alaska experienced an historic mass evacuation by air to relocate affected individuals. Halong remains among the strongest cyclones the area has ever seen. Its rapid intensification was fuelled by unusually warm north Pacific waters, which provided extra heat and moisture.

Twin Disasters in Mexico

At the same time, the nation faced two consecutive hits last week as the leftovers of Priscilla and Raymond combined, dumping about 609mm of rain in four days across the central and eastern areas. 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, worsening floods as Raymond approached. More than 300 communities were affected by landslides and overflowing rivers. By Wednesday, 66 fatalities were verified and 75 individuals are still unaccounted for. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in isolated areas.
