Japanese Islands Hit by Back-to-Back Tropical Storms
The Izu archipelago have faced yet another severe impact as Typhoon Nakri moved across the region on Monday, following in the footsteps of Typhoon Halong, which hit seven days prior.
Initial Consequences on Hachijojima Island
Local authorities on Hachijojima noted interruptions and destruction to about 220 homes after the typhoon brought an hour of rainfall totaling 37mm and gusts of up to 95mph (152km/h). Flight services were interrupted, public facilities harmed, and intense rains caused ground slides across the group of islands. The typhoon also generated 9-metre waves, creating dangerous coastal conditions. Off the Pacific coast in Oiso, in Kanagawa prefecture, three fishermen were carried off by waves, with one fatality reported.
Nakri's Transformation
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. Riding the jet stream, its remnants are on track to reach British Columbia, Canada, delivering intense precipitation, powerful gusts, and coastal flooding.
Remembering Halong's Impact
Seven days before, Halong discharged over 200mm of precipitation within three hours, as maximum sustained winds reached 122mph. By late morning last Thursday, rainfall totals reached 349mm, shattering the 24-hour record. The typhoon’s remnants then crossed the north 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 hardest hit. A single fatality occurred, homes were destroyed, and about 1,500 residents were forced into shelters. Alaska experienced an historic mass evacuation by air to relocate affected individuals. Halong remains among the strongest cyclones the region has experienced. Its rapid intensification was fuelled by abnormally hot northern Pacific seas, 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, releasing nearly 609mm of precipitation over 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. Search and relief efforts persist, with stagnant floodwaters raising health concerns in isolated areas.
