Japan's Archipelago Struck by Two Successive Tropical Storms

The Izu Islands have endured another powerful blow as tropical cyclone Nakri swept through the area on Monday, coming just after Typhoon Halong, which struck a week earlier.

Initial Consequences on the Island of Hachijojima

Local authorities on Hachijojima noted interruptions and destruction to approximately 220 residences after the typhoon brought 37mm (1.5in) of rain in one hour and wind bursts reaching 95mph. Flight services were interrupted, public facilities harmed, and intense rains caused ground slides across the island chain. The storm also generated 9-metre waves, leading to hazardous shoreline situations. Near Oiso on the Pacific side, in Kanagawa prefecture, 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 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 the Canadian province of British Columbia, bringing heavy rain, strong winds and storm surges.

Recalling Halong's Fury

A week earlier, Halong discharged more than 200mm of rain in three hours, as maximum sustained winds reached 122mph. By the late morning of the previous Thursday, precipitation levels climbed to 349mm, shattering the 24-hour record. The typhoon’s remnants then crossed the north 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 most affected. A single fatality occurred, 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 evacuate displaced residents. Halong stands as among the strongest cyclones the area has ever seen. Its quick strengthening was driven by abnormally hot northern Pacific seas, which provided extra heat and moisture.

Double Trouble in Mexico

Meanwhile, the country endured a double blow last week as the leftovers of Priscilla and Raymond combined, releasing nearly 609mm of precipitation over four days across the central and eastern areas. Steered by a dip in the jet stream, the two weather events struck the same zone one after another. The initial heavy rains 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 remain missing. Rescue and recovery operations are continuing, with standing water causing health worries in isolated areas.
