The 1960 Pacific hurricane season was an event in meteorology. It officially started on May 15, 1960 in the eastern Pacific and lasted until November 30, 1960. The 1960 season was the first season that Eastern Pacific Hurricanes were named.[1]

Eight tropical cyclones, seven named storms and five hurricanes formed during the 1960 season, none of the hurricanes reached beyond category 1 status on the Saffir-Simpson Hurricane Scale.[2]

Only one report of Gwen was submitted to the National Weather Bureau by the vessel Lord Lodrington early on October 4. The system was given the name Gwen and an Air Force reconnaissance aircraft sent to monitor the system. However by the time they reached the area where the hurricane was positioned, found the storm had completely dissipated. Due to the lack of reports no track data was produced for Gwen.[8]
