Japanese Archipelago Struck 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.

Initial Consequences on the Island of Hachijojima

Officials on Hachijojima Island reported disruption and damage to approximately 220 residences after the storm brought an hour of rainfall totaling 37mm and gusts of up to 95mph (152km/h). 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. Near Oiso on the Pacific side, in Kanagawa prefecture, three fishermen were carried off by waves, one of whom has been confirmed dead.

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 remaining parts are headed to reach British Columbia, Canada, 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 maximum sustained winds reached 122mph. By the late morning of the previous Thursday, precipitation levels climbed to 349mm, breaking the daily rainfall record. The typhoon’s remnants then crossed the north Pacific and arrived in Alaska on Sunday, bringing a record-breaking 2-metre storm surge.

Alaska's Severe Damage

The coastal villages of Kipnuk and Kwigillingok were the hardest hit. One person died, homes were destroyed, and about 1,500 residents were forced into shelters. The state underwent one of the largest airlifts in its history to evacuate displaced residents. Halong remains one of the most powerful storms the area has ever seen. Its quick strengthening was fuelled by abnormally hot northern Pacific seas, which provided extra heat and moisture.

Twin Disasters in Mexico

At the same time, the nation faced two consecutive hits last week as the leftovers of Priscilla and Raymond combined, dumping about 609mm of rain in four days across the central and eastern areas. Guided by a trough in the air current, the two weather events struck the same zone one after another. The first deluge from Priscilla made the soil waterlogged, worsening floods as Raymond approached. Over 300 localities 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.
