2006 Pacific typhoon season
The 2006 Pacific typhoon season was a near-average season that produced a total of 23 named storms, 15 typhoons, and six super typhoons. The season ran throughout 2006, though most tropical cyclones typically develop between May and October. The season's first named storm, Chanchu, developed on May 9, while the season's last named storm, Trami, dissipated on December 20. Also, this season was more active, costly, and deadly than the previous season.

Although Fabio did not impact land, its remnants produced heavy rainfall in Hawaii. In a 24-hour period, 2.89 inches (73 mm) of rainfall was recorded at Glenwood on the island of Hawaii; this was the highest daily rainfall total for the month on the island. However, the heaviest precipitation fell on Mount Waiʻaleʻale on Kauai, where 15.08 inches (383 mm) fell in 24 hours; this total alone was greater than all other monthly rainfall totals in the state. The heavy rainfall flooded the Hanalei River, which forced the closure of the Kuhio Highway when a bridge was inundated. On Oahu, the rainfall caused ponding on roadways and flooding along streams. One flooded stream stranded 24 hikers along a trail, all of whom required rescue by helicopter.
On July 17, a tropical wave exited Africa and crossed the Atlantic without developing. On July 25 it entered the Eastern Pacific, gradually developing an area of organized convection. Despite marginally favorable upper-level winds, the system organized enough to be declared a tropical depression on August 1, several hundred miles southwest of Acapulco, Mexico. Initially, the depression tracked west-northwestward. Despite wind shear in the area, the depression was upgraded to Tropical Storm Gilma later on August 1. The wind shear prevented further strengthening or organization, and Gilma weakened to a tropical depression early on August 2. The depression turned westward, and Gilma degenerated into a remnant low by August 4.
