The 2017 Pacific hurricane season was an above average Pacific hurricane season in terms of named storms,[nb 1] though less active than the previous three, featuring eighteen named storms, nine hurricanes, and four major hurricanes.[nb 2] Despite the considerable amount of activity, most of the storms were weak and short-lived. The season officially started on May 15 in the eastern Pacific Ocean, and on June 1 in the central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the respective regions. However, the formation of tropical cyclones is possible at any time of the year, as illustrated in 2017 by the formation of the season's first named storm, Tropical Storm Adrian, on May 9. At the time, this was the earliest formation of a tropical storm on record in the eastern Pacific basin proper (east of 140°W). The season saw near-average activity in terms of accumulated cyclone energy (ACE), in stark contrast to the extremely active seasons in 2014, 2015, and 2016; and for the first time since 2012, no tropical cyclones formed in the Central Pacific basin. However, for the third year in a row, the season featured above-average activity in July, with the ACE value being the fifth highest for the month. Damage across the basin reached $375.28 million (2017 USD),[nb 3] while 45 people were killed by the various storms.
Prior to the start of this season, the National Hurricane Center (NHC) changed its policy to permit issuance of advisories on disturbances that were not yet tropical cyclones but had a high chance to become one, and were expected to bring tropical storm or hurricane conditions to landmasses within 48 hours. As a result of this change, watches and warnings could be issued by local authorities. Such systems would be termed as "Potential Tropical Cyclones".[2] The first system to receive this designation was Potential Tropical Cyclone Fourteen-E, which developed into Tropical Storm Lidia south-southeast of the Baja California Peninsula on August 30.
