Japan's Archipelago Hit by Two Successive Tropical Storms

The Izu Islands have endured another powerful blow as tropical cyclone Nakri moved across the area on Monday, following in the footsteps of storm Halong, which hit seven days prior.

Initial Consequences on Hachijojima Island

Officials on Hachijojima Island reported disruption and damage to approximately 220 residences after the storm brought an hour of rainfall totaling 37mm and gusts of up to 95mph (152km/h). Airport operations were disrupted, public facilities harmed, and heavy rainfall triggered landslides 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 fishermen were carried off by waves, with one fatality reported.

The Evolution of Nakri

The storm has since shifted into an extratropical cyclone, losing strength while traveling east over cooler north Pacific waters, with wind speeds dropping to about 65mph as of Thursday. Moving along the air current, its remnants are on track to reach the Canadian province of British Columbia, delivering intense precipitation, powerful gusts, and coastal flooding.

Recalling Halong's Fury

Seven days before, 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, 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.

Alaska's Severe Damage

The coastal villages of 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. Alaska experienced one of the largest airlifts in its history to relocate affected individuals. Halong stands as one of the most powerful storms the area has ever seen. Its rapid intensification was fuelled by abnormally hot northern Pacific seas, which provided extra heat and moisture.

Twin Disasters in Mexico

At the same time, the country faced two consecutive hits last week as the leftovers of Priscilla and Raymond combined, 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 initial heavy rains from Priscilla made the soil waterlogged, worsening floods as Raymond approached. More than 300 communities were impacted by mudslides and river overflows. As of Wednesday, 66 fatalities were verified and 75 individuals are still unaccounted for. Search and relief efforts persist, with stagnant floodwaters raising health concerns in remote zones.
