Japanese Islands Struck by Two Successive Typhoons
The Izu archipelago have endured another powerful blow as Typhoon Nakri moved across the area on Monday, following in the footsteps of Typhoon Halong, which hit seven days prior.
Immediate Impact on the Island of Hachijojima
Local authorities on Hachijojima noted interruptions and destruction to approximately 220 residences after the typhoon brought 37mm (1.5in) of rain in one hour and wind bursts reaching 95mph. Airport operations were disrupted, infrastructure damaged, and heavy rainfall triggered landslides 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 fishermen were carried off by waves, one of whom has been confirmed dead.
The Evolution of Nakri
Nakri has since transitioned into an non-tropical storm system, 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 the Canadian province of British Columbia, 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, precipitation levels climbed to 349mm, shattering the 24-hour record. The typhoon’s remnants then traveled over the northern Pacific and reached Alaska on Sunday, causing an unprecedented 2-meter coastal surge.
Alaska's Severe Damage
The seaside communities Kipnuk and Kwigillingok were the hardest hit. One person died, 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 driven by unusually warm north Pacific waters, which provided extra heat and moisture.
Twin Disasters in Mexico
Meanwhile, the nation faced two consecutive hits last week as the leftovers of Priscilla and Raymond combined, 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 first deluge from Priscilla made the soil waterlogged, worsening floods as Raymond approached. Over 300 localities were impacted by mudslides and river overflows. By Wednesday, 66 people have been confirmed dead and 75 remain missing. Search and relief efforts persist, with standing water causing health worries in isolated areas.
