Japanese Archipelago Hit by Two Successive Tropical Storms
The Izu archipelago have faced yet another severe impact as Typhoon Nakri moved across the region on Monday, coming just after storm Halong, which struck seven days prior.
Immediate Impact on Hachijojima Island
Local authorities on Hachijojima reported disruption and damage to about 220 homes after the storm brought an hour of rainfall totaling 37mm 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 Kanagawa prefecture, three fishermen were carried off by waves, with one fatality reported.
Nakri's Transformation
The storm has since shifted into an non-tropical storm system, losing strength while traveling east over cooler north Pacific waters, with wind speeds dropping to about 65mph as of Thursday. Riding the jet stream, its remaining parts are headed to reach British Columbia, Canada, bringing heavy rain, strong winds and storm surges.
Remembering Halong's Impact
A week earlier, Halong discharged over 200mm of precipitation within three hours, as maximum sustained winds reached 122mph. By late morning last Thursday, precipitation levels climbed to 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.
Alaska's Severe Damage
The coastal villages of Kipnuk and Kwigillingok were the hardest hit. One person died, houses were ruined, and nearly 1,500 people had to evacuate to safe zones. The state underwent an historic mass evacuation by air to relocate affected individuals. Halong stands as one of the most powerful storms the region has experienced. Its quick strengthening was driven by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.
Double Trouble in Mexico
Meanwhile, the nation faced two consecutive hits 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, both systems hit the same area in quick succession. The initial heavy rains from Priscilla left the ground saturated, worsening floods as Raymond approached. Over 300 localities were impacted by mudslides and river overflows. By 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 remote zones.
