Iniki also was responsible for six deaths. Most damage was on the island of Kaua ʻi, where the storm destroyed thousands of homes and left a large amount of the island without power, although O ʻahu also suffered significant damage. Hurricane Iniki was the costliest hurricane to strike the state of Hawai ʻi, causing $1.8 billion ($2.6 billion in 2004 US dollars) in damage. The two main problems that occurred during the evacuation were lack of parking at shelters and exit routes for the coastlines. For those in need, vans and buses gave emergency transportation, while police manned certain overused intersections. The execution of the evacuations went well, beginning with the vulnerable coastal area. Roughly one-third of O ʻahu's population participated in the evacuation, though many others went to the house of a family member or friend for shelter. Public school buildings acted as shelters, and were for refuge only, meaning they did not provide food, cots, blankets, medications or other comfort items. Though not hit by the hurricane, Iniki's large wind field caused nearly 30,000 people to evacuate to 110 public shelters in O ʻahu. The CPHC issued a tropical storm warning for O ʻahu on September 11 which was upgraded to a hurricane warning later that day. Because schools were cancelled, traffic was light and evacuation was well-executed. During the evacuation of the island, people left days before to family, friends or shelters. Rather than sending tourists to public shelters, two major hotels kept their occupants in the buildings during the storm's passage. Prior to Iniki's arrival in Kaua ʻi, 8,000 people were housed in shelters, most of whom remembered Hurricane Iwa 10 years prior. Ī hurricane watch was issued for Kaua ʻi early on September 11 and was upgraded to a hurricane warning later that day. It was not until a special bulletin was issued by the CPHC at 6:30 PM on September 10 - less than 24 hours before landfall - that any warning was given to the public. CHPC Advisory #19 was issued at 11 AM local time on September 10, and suggested that a weakening Iniki would remain well to the south. Some of the standard international computer models were indicating a northward turn towards the populated Hawaiian Islands, but these were rejected by the CPHC forecasters. For several days prior to the disaster, the CPHC and the news media forecast Iniki to remain well south of the island chain, with the only effect being some high surf conditions. The Central Pacific Hurricane Center (CPHC) failed to issue tropical cyclone warnings and watches for the hurricane well in advance. Hurricane Iniki rapidly weakened and went extra tropical Midway between Also and Hawaii.


On September 11, Iniki peaked as Category 4 hurricane and hit Hawaii with wind of 145 mph. It turned north towards Hawaii and became major Hurricane the next day. Iniki continued to get stronger and became a hurricane on September 9. The depression continued quickly westward and remained weak until the 8th, when it slowed enough to strengthen to a tropical storm. Conditions slowly became more favorable, and, as the convection concentrated around a center, the wave was classified Tropical Depression Eighteen-E on September 5, located 1,700 miles (2700 km) southwest of Cabo San Lucas, Mexico or 1550 miles (2500 km) east-southeast of Hilo, Hawai ʻi. the shock wave continued to go west, and remained disorganized. It moved westward across the unfavorable Atlantic Ocean and crossed Central America into the Pacific on the 28th. The origin of Iniki is unclear, but it possibly began as a tropical wave that moved off the African coast on August 18.
