Japanese Archipelago Hit by Back-to-Back Typhoons

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

Initial Consequences on Hachijojima Island

Local authorities on Hachijojima reported disruption and damage to approximately 220 residences after the storm brought 37mm (1.5in) of rain in one hour 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, creating dangerous coastal conditions. Near Oiso on the Pacific side, in the Kanagawa region, three fishermen were carried off by waves, with one fatality reported.

The Evolution of Nakri

Nakri has since transitioned into an extratropical cyclone, weakening as it moved eastwards over cooler north Pacific waters, with wind speeds dropping to about 65mph as of Thursday. Moving along the air current, its remaining parts are headed to reach the Canadian province of British Columbia, 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, precipitation levels climbed to 349mm, breaking the daily rainfall record. The storm's leftovers then traveled over the northern Pacific and reached Alaska on Sunday, bringing a record-breaking 2-metre storm surge.

Significant Harm in Alaska

The seaside communities Kipnuk and Kwigillingok were the hardest hit. A single fatality occurred, houses were ruined, and nearly 1,500 people had to evacuate to safe zones. The state underwent one of the largest airlifts in its history to evacuate displaced residents. Halong stands as among the strongest cyclones the region has experienced. Its quick strengthening was fuelled by unusually warm north Pacific waters, which supplied additional warmth and humidity.

Twin Disasters in Mexico

At the same time, the nation endured a double blow last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond combined, dumping about 609mm of rain in 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 left the ground saturated, intensifying flooding when Raymond arrived. More than 300 communities were affected by landslides and overflowing rivers. By Wednesday, 66 fatalities were verified and 75 remain missing. Rescue and recovery operations are continuing, with standing water causing health worries in remote zones.
