Japan's Islands Struck by Back-to-Back Tropical Storms
The Izu Islands have faced yet another severe impact as Typhoon Nakri swept through the area on Monday, coming just after Typhoon 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 37mm (1.5in) of rain in one hour and gusts of up to 95mph (152km/h). Airport operations were disrupted, infrastructure damaged, and intense rains caused ground slides across the island chain. The storm also produced waves as high as 9 meters, leading to hazardous shoreline situations. Near Oiso on the Pacific side, in the Kanagawa region, three fishermen were carried off by waves, with one fatality reported.
Nakri's Transformation
Nakri has since transitioned into an extratropical cyclone, losing strength while traveling east over cooler north Pacific waters, with gusts reducing to around 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.
Recalling Halong's Fury
A week earlier, Halong discharged over 200mm of precipitation within three hours, as maximum sustained winds reached 122mph. By the late morning of the previous Thursday, rainfall totals reached 349mm, breaking the daily rainfall record. The typhoon’s remnants then traveled over the northern Pacific and arrived in 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. Alaska experienced an historic mass evacuation by air to relocate affected individuals. Halong remains one of the most powerful storms the area has ever seen. Its rapid intensification was fuelled by unusually warm north Pacific waters, which provided extra heat and moisture.
Double Trouble in Mexico
Meanwhile, the country faced two consecutive hits last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond converged, dumping about 609mm of rain in four days across the central and eastern areas. Guided by a trough in the air current, 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. More than 300 communities were impacted by mudslides and river overflows. By Wednesday, 66 people have been confirmed dead and 75 remain missing. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in isolated areas.
