Japan's Islands Hit by Two Successive Typhoons

The Izu archipelago have endured another powerful blow as tropical cyclone Nakri swept through the region on Monday, coming just after Typhoon Halong, which struck seven days prior.

Immediate Impact on the Island of Hachijojima

Local authorities on Hachijojima noted interruptions and destruction to about 220 homes after the typhoon brought an hour of rainfall totaling 37mm and wind bursts reaching 95mph. Airport operations were disrupted, public facilities harmed, and intense rains caused ground slides across the island chain. 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, with one fatality reported.

The Evolution of Nakri

Nakri has since transitioned into an extratropical cyclone, weakening as it moved eastwards over chilled northern Pacific seas, 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 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 reached Alaska on Sunday, bringing a record-breaking 2-metre storm surge.

Alaska's Severe Damage

The coastal villages of 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 one of the largest airlifts in its history to relocate affected individuals. Halong remains among the strongest cyclones the region has experienced. 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 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 left the ground saturated, intensifying flooding when Raymond arrived. 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.
