The 2006 Central Pacific hurricane season began on June 1, 2006 and ended on November 30, 2006. However, no storms existed in the basin until July 24, when Hurricane Daniel crossed over. Cyclones that form in this basin are tracked by the Central Pacific Hurricane Center. The Joint Typhoon Warning Center also tracks storms in this basin, although it is not an official RSMC. The RMSC in the basin is the CPHC.

2006 was a more active season, with 4 tropical depressions forming, the most since the 1997 season. However, only one was significant, Hurricane Ioke. Ioke became the strongest Central Pacific cyclone in recorded history.

The Eastern Pacific's Hurricane Daniel crossed over into the Central North Pacific basin early on July 24 and was predicted to affect Hawaii as a tropical storm.[1] However, Daniel encountered weak steering currents in the open ocean, causing it to slow down considerably. It rapidly degenerated to a tropical depression on July 25 and the CPHC issued its last advisory on July 26 while the storm was still well to the east of Hawaii. The remnant circulation continued east, passing south of the Big Island of Hawaii of July 28. The remnant low dissipated at 1200 UTC on July 28.[1]
Rains of 2-5 inches were recorded around Hawaii and Maui. Daniel also produced easterly winds to the main islands. Gusts reached as high as 35 - 45 mph.[1]

- Main article: Hurricane Ioke
A persistent tropical disturbance embedded in a trough gained convection and developed into a tropical depression about 775 miles south of Honolulu on August 19. It continued to strengthen, and the Central Pacific Hurricane Center upgraded the depression to a tropical storm, just six hours after forming. The Central Pacific Hurricane Center designated the system with the name Ioke (IPA /iːˈəʊ.keɪ/), which is Hawaiian for the name Joyce,[2] becoming the first tropical storm to form in the Central Pacific since 2002. After undergoing rapid development, Ioke strengthened into a hurricane just 24 hours after it had formed; it continued to rapidly intensify and became a major hurricane (Category 3 or greater) on the morning of August 21. Later that day, Ioke intensified even further into a Category 4 hurricane. On August 22, it began to weaken, and was downgraded back to a Category 2. The National Weather Service reported that the eastern eyewall of Ioke passed over the uninhabited Johnston Atoll,[3] buffeting it with hurricane-force winds. The storm began to deepen again late on August 23 as it moved over increasingly warm water, reaching major hurricane status for the second time while moving to the west-northwest.
Twelve people on a United States Air Force vessel in the Pacific were forced to abandon ship and take shelter in a hurricane-proof bunker on the island.[4] They were reported safe the next day, and a reconnaissance flight reported little damage on the island.[5]
Overnight between August 24 and August 25, Ioke strengthened into a Category 5 hurricane, the first system originating from the Central Pacific to reach that intensity while still in the Western hemisphere. Ioke then weakened back to a Category 4 while undergoing an eyewall replacement cycle, regaining Category 5 strength on August 26.[6] It is the most intense hurricane ever to develop in the Central Pacific, with a central pressure of 915 mbar (27.17 inHg). Ioke is only the fifth Category 5 hurricane on record in the Central Pacific, and the first one since Hurricane John in 1994.[7]

|---|---|---|---|---|

| Intensity | 35 mph (55 km/h), 1007 mbar (hPa) | |||
Tropical Depression Two-C formed in the Central Pacific's Intertropical Convergence Zone around 1600 UTC on September 18.[8] Maximum sustained winds in Tropical Depression 2-C raised from 30 mph to 35 mph early on September 19. Wind shear had been light most of the time, but high pressures at mid and upper levels caused it to become stronger. On September 20, the depression had lost its low-level circulation and advisories by the Central Pacific Hurricane Center were discontinued.[8]
Operationally, Tropical Depression Two-C was thought to be the remnant low of Hurricane Kristy, which had dissipated on September 8.[8] However, the disturbance that became Two-C had actually formed west of Kristy's remnants and was a different season. However, this was only found in the post-season analysis.
[edit] Tropical Depression Three-C
|

|---|---|---|---|---|
|

| Duration | September 26 – September 27, 2006 | |||
| Intensity | 35 mph (55 km/h), 1007 mbar (hPa) | |||
A disorganized tropical disturbance near the International Date Line formed on September 25.[9] A low-level circulation appeared early on the 26th, with the Central Pacific Hurricane Center initalizing advisories at 2100 UTC the same day. Winds had sustained at 35 mph, but the depression had issues maintaining strength. By the morning of September 27, Tropical Depression 3-C no longer had a low-level circulation and the CPHC ceased advisories just before the dateline.
[edit] Tropical Depression Four-C
|

|---|---|---|---|---|
|

| Duration | October 13 – October 14, 2006 | |||
| Intensity | 35 mph (55 km/h), 1007 mbar | |||
An area of thunderstorm activity and convection was first spotted in the ITCZ on October 8. Taking a long time to organise, Tropical Depression Four-C formed about 750 miles (1200 km) SW of Honolulu, Hawaii on October 13. Wind shear caused an exposed low-level circulation and therefore advisories were discontinued on October 14. The remnants of TD-4C fuelled heavy rainfall and flooding on Big Island.[10]

The table on the right shows the ACE for each storm in the season. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength.
[edit] Storm names
Storms that formed in the central Pacific are given names from a sequential list; in 2006, the name Ioke was used from this list, the first time a name from the Central Pacific list had been used since the 2002 season.
The name Ioke was retired after the 2006 season for two reasons. The first was how significant it was. The second was because "Ioke" is an incorrect Hawaiian word, thus having no meaning. Had Ioke not been like it was, it still would've been removed due to this.
