Timeline of the 2006 Pacific hurricane season explained

The 2006 Pacific hurricane season was the most active since the 2000 season, producing 21 tropical depressions; 19 of which became tropical storms or hurricanes. The season officially started on May 15, 2006 in the eastern Pacific, designated as the area east of 140°W, and on June 1, 2006 in the central Pacific, which is between the International Date Line and 140°W, and lasted until November 30, 2006. These dates typically limit the period of each year when most tropical cyclones form in the eastern Pacific basin. This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation. The timeline also includes information which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned on, have been included.

The first storm of the season, Tropical Storm Aletta, formed off the southwest coast of Mexico. After no storms formed in June, the season became active again in July when five named storms developed, including Hurricane Daniel, which was the second strongest storm of the season. Six storms formed during August, including Hurricane Ioke and Hurricane John. September was a relatively inactive month, producing only 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.
