2006 Pacific Hurricane Season

The 2006 Pacific hurricane season was the most active since 2000, which also produced 19 tropical storms or hurricanes. Eighteen developed within the National Hurricane Center (NHC) area of warning responsibility, which is east of 140°W, and one storm formed between 140°W and the International Date Line, which is under the jurisdiction of the Central Pacific Hurricane Center (CPHC). Of the 19 total storms, eleven became hurricanes, of which six attained major hurricane status. Within the NHC portion of the basin, the season officially began on May 15, and in the CPHC portion, it started on June 1; the season officially ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the eastern Pacific basin.

The strongest storm of the season was Hurricane Ioke, which reached Category 5 status on the Saffir-Simpson scale in the central Pacific Ocean; Ioke passed near Johnston Atoll and later Wake Island, where it caused heavy damage but no deaths. The deadliest storm of the season was Hurricane John, which killed six people after striking the Baja California Peninsula, and the costliest storm was Hurricane Lane, which caused $203 million in damage in southwestern Mexico (2006 USD, $234 million 2012 USD).

Seasonal activity began on May 27 when Tropical Storm Aletta formed off the southwest coast of Mexico. No storms formed in June, though the season became active in July when five named storms developed, including Hurricane Daniel which was the second strongest storm of the season. During August, Hurricanes Ioke and John formed, as well as four other storms. September was a relatively quiet month with two storms, of which one was Hurricane Lane. Three storms developed in October and two formed in November; this marked the first time on record when more than one tropical storm developed in the basin during the month of November.
