Japanese Archipelago Struck by Two Successive Tropical Storms
The Izu archipelago have endured another powerful blow as Typhoon Nakri swept through the region on Monday, coming just after storm Halong, which struck seven days prior.
Initial Consequences on the Island of Hachijojima
Officials on Hachijojima Island reported disruption and damage to approximately 220 residences 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 group of islands. The typhoon also generated 9-metre waves, leading to hazardous shoreline situations. Off the Pacific coast in Oiso, in the Kanagawa region, three men were swept away while fishing, one of whom has been confirmed dead.
Nakri's Transformation
Nakri has since transitioned into an non-tropical storm system, weakening as it moved eastwards over cooler north Pacific waters, with gusts reducing to around 65mph as of Thursday. Moving along the air current, its remnants are on track to reach the Canadian province of British Columbia, bringing heavy rain, strong winds and storm surges.
Remembering Halong's Impact
Seven days before, Halong had unleashed over 200mm of precipitation within three hours, as peak wind speeds hit 122mph. By the late morning of the previous Thursday, precipitation levels climbed to 349mm, breaking the daily rainfall record. The storm's leftovers then traveled over the northern Pacific and reached 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 about 1,500 residents were forced into shelters. Alaska experienced an historic mass evacuation by air to evacuate displaced residents. Halong remains among the strongest cyclones the region has experienced. Its rapid intensification was fuelled by abnormally hot northern Pacific seas, which supplied additional warmth and humidity.
Twin Disasters in Mexico
Meanwhile, the country 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 initial heavy rains from Priscilla made the soil waterlogged, worsening floods as Raymond approached. Over 300 localities were affected by landslides and overflowing rivers. As of Wednesday, 66 fatalities were verified and 75 individuals are still unaccounted for. Rescue and recovery operations are continuing, with stagnant floodwaters raising health concerns in isolated areas.
