The Izu Islands have endured another powerful blow as tropical cyclone Nakri moved across the region on Monday, following in the footsteps of storm Halong, which hit a week earlier.

Initial Consequences on the Island of Hachijojima

Local authorities on Hachijojima 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 produced waves as high as 9 meters, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, in the Kanagawa region, three fishermen were carried off by waves, one of whom has been confirmed dead.

The Evolution of Nakri

The storm has since shifted into an non-tropical storm system, weakening as it moved eastwards over cooler north Pacific waters, 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, bringing heavy rain, strong winds and storm surges.

Remembering Halong's Impact

Seven days before, Halong discharged more than 200mm of rain in 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 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. The state underwent an historic mass evacuation by air to evacuate displaced residents. Halong remains one of the most powerful storms the area has ever seen. Its rapid intensification was fuelled by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.

Double Trouble in Mexico

Meanwhile, the country endured a double blow last week as the remnants of Hurricane Priscilla and Tropical Storm Raymond converged, dumping about 609mm of rain in four days across central and eastern regions. Steered by a dip in the jet stream, both systems hit the same area in quick succession. The initial heavy rains from Priscilla made the soil waterlogged, worsening floods as Raymond approached. More than 300 communities were affected by landslides and overflowing rivers. As of Wednesday, 66 fatalities were verified and 75 remain missing. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in isolated areas.
