Hurricane Kristy was the twelfth cyclone and eighth hurricane of the 2006 Pacific hurricane season. Hurricane Kristy was the longest lasting storm of the season in the NHC's area of responsibility with 36 advisories.
Kristy formed as a tropical wave off of Dakar on August 13 and was indentified as a circulation of clouds. The wave spent two weeks crossing the Atlantic Ocean and increased in convection on August 29. Dvorak classified that the swirl strengthened into a depression on August 30 and a storm six hours later. Kristy strengthened further, becoming a 80 mph (130 km/h)/985 millibar hurricane on August 31. Soon afterwards, wind shear from the stronger Hurricane John caused Kristy to weaken. Steering currents collapsed as Kristy moved westward and Kristy moved around, flucuating in strength. Kristy finally weakened into a low pressure system on September 8.
In a rare coincidence, Hurricanes John, Kristy and Ernesto were all active systems on August 30 and August 31.[1]

[edit] Storm History
Kristy originated from a tropical wave that crossed Dakar on August 13, being identified as a low swirl of clouds. The wave spent two weeks traversing the Atlantic Ocean, the Carribean Sea and most of the eastern north Pacific Ocean. The wave moved west and started increasing in convection on August 29. Dvorak classifications estimated that the wave developed into a tropical depression around 0000 UTC August 30 near Baja California. However, the first discussion was released late on August 29 by meteorologist James Franklin as Tropical Depression 12-E. [2]
Six hours after becoming a depression, it denied the forecaster's prediction to dissipate before becoming a named storm by strengthening into Tropical Storm Kristy, the eleventh storm of the year.[3] Kristy strengthened further, becoming a hurricane on August 31 and peaked winds at 80 mph with a pressure of 985 mbar. Around 1200 UTC the same day, an eye-like feature was recoginized in Kristy's circulation through microwave images. Wind shear from the stronger Hurricane John caused Kristy to weaken while approaching Baja California. Kristy weakened into a storm and rapid degeneration was forecasted within days.[4][5]
Soon afterwards, steering collapsed and Kristy wandered around the Pacific for a few days, throwing the National Hurricane Center off course predicting the storm's track. A strengthening subtropical ridge and a tropical low were predicted to send Kristy to the southwest on September 2. The western side of Kristy started having bursts of convection.[6]Kristy weakened into a tropical depression, started fluctuating in strength on its way toward Hawaii, going back between storm and depression status three times within days. Kristy, as a depression, weakened into a 20 mph remnant low on September 8 and degenerated into an area of low pressure the next day and was forecasted to dissipate two days later.[7][8][9][10]
[edit] Impact, Records and Naming
No damage or fatalities were reported as Hurricane Kristy or the precursor. The 70-knot winds were estimated by Dvorak classifications.[9] Isla Socorro and Isla Clarion were predicted to get battered with tropical storm winds on August 30. By that evening, as Kristy moved away from land, only Isla Clarion had a chance of only 34-knot winds.[11][12]
Hurricane Kristy was the longest lasting storm of the season in the NHC's area of responsibility with 36 advisories. This was the sixth use of the name Kristy, previously being used in the 1978, 1982, 1988, 1994 and 2000 Pacific hurricane seasons.
