Japan's Archipelago Hit by Two Successive Tropical Storms
The Izu Islands have faced yet another severe impact as tropical cyclone Nakri swept through the region on Monday, coming just after storm Halong, which hit seven days prior.
Initial Consequences on Hachijojima Island
Local authorities on Hachijojima 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). Flight services were interrupted, public facilities harmed, and heavy rainfall triggered landslides across the group of islands. The typhoon also produced waves as high as 9 meters, 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.
Nakri's Transformation
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 remnants are on track to reach British Columbia, Canada, delivering intense precipitation, powerful gusts, and coastal flooding.
Remembering Halong's Impact
A week earlier, Halong had unleashed more than 200mm of rain in three hours, as peak wind speeds hit 122mph. By the late morning of the previous Thursday, rainfall totals reached 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 hardest hit. One person died, 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 region has experienced. Its rapid intensification was driven by unusually warm north Pacific waters, which provided extra heat and moisture.
Double Trouble 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 the central and eastern areas. Steered by a dip in the jet stream, 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 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.
