Storm names

The following names were used for tropical storms that formed in the North Pacific Ocean east of 140°W during 1965. The names came from a series of four rotating lists. Names were used one after the other without regard to year, and when the bottom of one list was reached, the next named storm received the name at the top of the next list. As the final tropical storm of the 1964 season was given the "T" name from list 2, the first two storms of the 1965 season were given the "V" and "W" names from that list ("U" being excluded). However, when it came time to assign a name to the season's third storm, instead of moving to the "A" name on list 3 ("X", "Y", and "Z" being excluded), forecasters returned the list 2 "A" name and proceeded from there. Had any tropical storms formed in the North Pacific between 140°W and the
