Japanese Islands 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 struck a week earlier.
Initial Consequences on the Island of Hachijojima
Officials on Hachijojima Island noted interruptions and destruction to approximately 220 residences 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 heavy rainfall triggered landslides across the group of islands. The storm also produced waves as high as 9 meters, leading to hazardous shoreline situations. Near Oiso on the Pacific side, in Kanagawa prefecture, three men were swept away while fishing, with one fatality reported.
The Evolution of Nakri
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 remnants are on track to reach the Canadian province of British Columbia, delivering intense precipitation, powerful gusts, and coastal flooding.
Remembering Halong's Impact
A week earlier, Halong discharged more than 200mm of rain in 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 storm's leftovers then traveled over the northern Pacific and arrived in Alaska on Sunday, causing an unprecedented 2-meter coastal surge.
Alaska's Severe Damage
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. The state underwent an historic mass evacuation by air to relocate affected individuals. Halong remains among the strongest cyclones the area has ever seen. Its quick strengthening was fuelled by abnormally hot northern Pacific seas, which provided extra heat and moisture.
Double Trouble in Mexico
At the same time, the country endured a double blow last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond converged, releasing nearly 609mm of precipitation over 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 initial heavy rains from Priscilla left the ground saturated, intensifying flooding when Raymond arrived. More than 300 communities were impacted by mudslides and river overflows. As of Wednesday, 66 people have been confirmed dead and 75 individuals are still unaccounted for. Search and relief efforts persist, with stagnant floodwaters raising health concerns in remote zones.
