Japanese Archipelago Hit by Back-to-Back Typhoons
The Izu archipelago have endured another powerful blow as tropical cyclone Nakri swept through the area on Monday, following in the footsteps of storm Halong, which hit seven days prior.
Immediate Impact on Hachijojima Island
Officials on Hachijojima Island reported disruption and damage to about 220 homes after the typhoon brought 37mm (1.5in) of rain in one hour and gusts of up to 95mph (152km/h). Flight services were interrupted, public facilities harmed, and intense rains caused ground slides across the island chain. The typhoon also generated 9-metre waves, creating dangerous coastal conditions. 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
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. Riding the jet stream, 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 over 200mm of precipitation within 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 storm's leftovers then crossed the north Pacific and reached Alaska on Sunday, causing an unprecedented 2-meter coastal surge.
Significant Harm in Alaska
The coastal villages of Kipnuk and Kwigillingok were the most affected. 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 remains among the strongest cyclones the region has experienced. Its rapid intensification was fuelled by unusually warm north Pacific waters, which supplied additional warmth and humidity.
Double Trouble in Mexico
Meanwhile, 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, the two weather events struck the same zone one after another. The first deluge from Priscilla left the ground saturated, worsening floods as Raymond approached. Over 300 localities were impacted by mudslides and river overflows. As of 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.
