From Wikipedia, the free encyclopedia
Hurricane Ioke (was also Typhoon Ioke, international designation: 0612, JTWC designation: 01C, and sometimes called Super Typhoon Ioke) was the strongest hurricane ever recorded in the Central Pacific. The first storm to form in the Central Pacific in the 2006 Pacific hurricane season, Ioke was a record breaking, long-lived and extremely powerful storm that traversed the Pacific for 19 days, reaching the equivalent of Category 5 status on the Saffir-Simpson Hurricane Scale three times.
The cyclone developed from the Intertropical Convergence Zone on August 20 far to the south of Hawaii. Encountering warm waters, little wind shear, and well-defined outflow, Ioke intensified from a tropical depression to Category 4 status within 48 hours. Late on August 22 it rapidly weakened to Category 2 status before crossing over Johnston Atoll. Two days later favorable conditions again allowed for rapid strengthening, and Ioke attained Category 5 status on August 25 before crossing the International Date Line. As it continued westward its intensity fluctuated, and on August 31 it passed near Wake Island with winds of 155 mph (250 km/h). Ioke gradually weakened as it turned northwestward and northward, and by September 6 it had transitioned into an extratropical cyclone. The remnants of Ioke accelerated northeastward and ultimately crossed into Alaska.
Ioke did not affect any permanently populated areas in the Central Pacific or Western Pacific basins as a hurricane or a typhoon. A crew of 12 people rode out the hurricane in a hurricane-proof bunker on Johnston Atoll; the crew estimated winds reached over 100 mph (160 km/h), which damaged trees on the island but did not impact the island bird population. The hurricane left moderate damage on Wake Island totaling $88 million (2006 USD), including blown off roofs and damaged buildings, though the infrastructure of the island was left intact; all military personnel were evacuated from the island. Later, the extratropical remnants of Ioke produced a severe storm surge along the Alaskan coastline, causing beach erosion.
