Hurricane Iniki

Hurricane Iniki (Hawaiian for Enid[3]) was the most powerful hurricane to strike the state of Hawaii and the Hawaiian Islands in recorded history. Forming during the strong El Niño of 1991-1994, Iniki was one of eleven Central Pacific tropical cyclones during the 1992 season. The eye of Hurricane Iniki passed directly over the island of Kauai on September 11, 1992 as a Category 4 hurricane on the Saffir-Simpson Hurricane Scale. It was the first hurricane to hit the state since Iwa in the Template:Tcseason, and the first major hurricane since Hurricane Dot in 1959.

Iniki caused around $1.8 billion (1992 US dollars) in damage and 6 deaths. At the time, Iniki was among the costliest United States hurricanes and remains the costliest hurricane on record in the eastern Pacific. The storm struck just weeks after Hurricane Andrew, the costliest tropical cyclone ever at the time, struck the U.S. state of Florida.

Due to well-executed warnings, Iniki caused only six deaths. Damage was greatest on Kauai, where the hurricane destroyed over 1,400 houses and severely damaged over 5,000. Oahu, though not directly in the path, experienced moderate damage from storm surge, though damage was much less there.

The origin of Iniki is unclear, but it possibly began as a tropical wave that exited the African coast on August 18. It moved westward across the unfavorable Atlantic Ocean and crossed Central America into the Pacific on the 28th. The wave continued rapidly westward and remained disorganized. Conditions slowly became more favorable, and, as the convection concentrated around a center, the wave was classified Tropical Depression Fourteen-E on September 5, located 1700 miles (2700 km) southwest of Cabo San Lucas, Mexico or 1550 miles (2500 km) east-southeast of Hilo, Hawai'i. The depression continued quickly westward and remained weak until the 8th, when it slowed enough to strengthen to a tropical storm. Because it had already crossed 140º west, it was considered part of the central Pacific hurricane basin and was named Tropical Storm Iniki from the central Pacific naming list.

Iniki as a newly-formed tropical storm

Located at the southern periphery of a subtropical ridge, Iniki continued westward and strengthened over the unusually favorable central Pacific; it reached hurricane status on September 9 while 470 miles (760 km) south-southeast of Hilo. The subtropical ridge, which typically keeps hurricanes well away from the Hawaiian islands, weakened due to an approaching upper level-trough and allowed Iniki to turn to the northwest. With very favorable upper-level outflow and warm water temperatures, Iniki steadily intensified, and attained major hurricane status on September 10 while south-southwest of the island chain.[3]

As Iniki turned to the north, it continued to strengthen, reaching a peak of 145 mph (230 km/h) winds on September 11 while 170 miles (270 km) south-southwest of Poipu on the island of Kauai. It continued rapidly to the northeast, and made landfall on south-central Kauai early on the 12th with winds of 140 mph (220 km/h), making Iniki a Category 4 hurricane on the Saffir-Simpson Hurricane Scale. After crossing the island, Iniki rapidly accelerated north-northeastward, weakened rapidly, and was absorbed by a cold front as it lost tropical caharcteristics and became extratropical on September 13 about halfway between Alaska and Hawaii.[3]

Preparations

The Central Pacific Hurricane Center (CPHC) issued tropical cyclone warnings and watches for the hurricane well in advance. Accurate forecasts allowed effective evacuations, minimizing deaths on the islands.

A Hurricane Watch was issued for Kauai early on September 11 and was upgraded to a Hurricane Warning later that day.[3] Prior to Iniki's arrival in Kauai, 8,000 people were housed in shelters, most of whom remembered Hurricane Iwa 10 years prior. Rather than sending tourists to public shelters, two major hotels kept their occupants in the buildings during the storm's passage. During the evacuation of the island, people left days before to either family, friends, or to shelters. Because schools were cancelled, traffic was light, and evacuation was well-executed.[4]

The CPHC issued a Tropical Storm Warning for Oahu on September 11 which was upgraded to a Hurricane Warning later that day.[3] Though not hit by the hurricane, Iniki's large wind field caused nearly 30,000 people to evacuate to 110 public shelters in Oahu. Public school buildings acted as shelters, and were for refuge only, meaning they did not provide food, cots, blankets, medications or other comfort items. Roughly one-third of Oahu's population participated in the evacuation, though many others went to a family or friend's house for shelter. The execuation of the evacuations went well, beginning with the vulnerable coastal area. For those in need, vans and buses gave emergency transportation, while police manned certain overused intersections. The two main problems that occurred during evacuating were lack of parking at shelters and exit routes for the coastlines.[4]

Hurricane Iniki was the costliest hurricane to strike the state of Hawaii, causing $1.8 billion ($2.6 billion in 2004 US dollars) in damage. Most damage was on the island of Kauai, where the storm destroyed thousands of homes and left a large amount of the island without power, although Oahu also suffered significant damage. Iniki also was responsible for 6 deaths.[3]

The hurricane nearly struck the Central Pacific Hurricane Center in Honolulu. Had it hit there, Iniki, along with Hurricane Andrew and Typhoon Omar, would have struck each of the three National Weather Service offices responsible for tropical cyclone warnings within a two-month period.[19]

Kauai

Hurricane Iniki made landfall on the south-central portion of Kauai island, bringing its dangerous inner core to the entire island.[3] Upon making landfall the hurricane produced storm tides of 4.5–6 feet (1.4–1.8 m), with some portions of the coastlines having high water marks of up to 18 feet (5.5 m). In addition, strong waves of up to 35 feet (10.5 m) in height crashed along the southern coastline for several hours, causing a debris line of more than 800 feet (250 m) inland. Because it moved quickly through the island, there were no reports of significant rainfall.[4]

Wind damage to trees from Iniki

Hurricane Iniki's high winds caused extensive damage in Kauai. 1,421 houses were completely destroyed, and 63 were lost from the storm surge and wave action. 5,152 homes were severely damaged, while 7,178 received minor damage.[3] On the south coast, hotels and condominiums received severe damage as well. A few were restored quickly, though some took several years to be rebuilt. One hotel, the Coco Palms Resort famous for Elvis' Blue Hawaii, remained closed over 10 years after the hurricane.[20] Destroyed housing across the island left more than 7,000 people homeless after the storm's passage.[21]

Sidewalk and tree damage from Iniki

Iniki's Category 4 winds also downed 26.5% of the island's transmission poles, 37% of its distribution poles, and 35% of its 800 mile (1300 km) distribution wire system. The entire island lacked electricity and television service for an extended period of time.[21] Electric companies restored only 20% of the island's power service within four weeks of Iniki. Also affected by the storm was the agricultural sector.[3] Though much of the sugar cane was already harvested, [21] what was left was severely damaged. The winds destroyed tender tropical plants like bananas and papayas and uprooted or damaged fruit and nut trees.[3]

Most of Iniki's damage occurred in Kauai. On the island, one person died when struck by debris, while another lost her life when a portion of her house fell on her. Offshore, two Japanese nationals died when their boat capsized. The reduced death toll was likely due to well-executed warnings and preparation. More than 100 injuries can be attributed to Iniki, though most occurred in the aftermath of the hurricane.[3]

Among those on Kauai was filmmaker Steven Spielberg, who was preparing for the final day of shooting of the movie Jurassic Park. He and his 130 cast and crew remained safely in a hotel during Iniki's passage.[22]

Oahu

Upon passing by Oahu, Iniki produced tides of 1.7–3 feet (0.5–0.9 m) above normal.[4] Prolonged periods of high waves severely eroded and damaged the southwestern coast of Oahu, with the areas most affected being Barbers Point through Kaena Point.[3] The Waianae coastline experienced the most damage, with waves and storm surge flooding the second floor of beachside apartments.[23] In all, Hurricane Iniki caused several million dollars in property damage,[4] and 2 deaths in Oahu.[3]

Aftermath

Storm surge from Iniki

Immediately after the storm, many were relieved to have survived the worst of the Category 4 hurricane; their complacency turned to apprehensiveness due to lack of information, as every radio station was out and there was no news available for several days. Using food from unpowered refrigerators and freezers, communities held lavish parties to overcome the situation. Though food markets allowed those affected to take what they needed, many Kauai citizens insisted on paying. Because the hurricane destroyed much of their belongings, many groups gathered for video parties powered by portable generators. In addition, entertainers from all of Hawaii, including the Honolulu Symphony, provided free concerts to the victims.[20]

Looting occurred in the aftermath of Iniki, though it was very minor. A group of Army Corps of Engineers, who experienced the looting of Hurricane Andrew just weeks before, were surprised at the overall calmness and lack of violence on the island. Kauai citizens remained hopeful for monetary aid from the government or insurance companies, though after six months they felt annoyed with the lack of help.[20] The military effectively provided aid for their immediate needs, though, and help arrived before local officials requested aid.[24]

In the months after the storm, many insurance companies left Hawaii. To combat this, State Governor John D. Waihee III enacted the Hurricane Relief Fund in 1993 to help unprotected Hawaiians. The fund was never needed for another Hawaii hurricane, and it was stopped in 2000 when insurance companies returned to the island.[25]

The name Iniki was retired due to this storm in 1993, and was replaced with Iolana in the Central North Pacific tropical storm list. Since that list is rotated through regardless of year, Iolana has not been used for any storm and is not likely to be used for decades due to the relative rarity of storm formation in the Central Pacific.
