The 1970 Pacific hurricane season began on May 15, 1970 in the east Pacific, and on June 1, 1970 in the central Pacific. It ended on November 30, 1970. These dates conventionally delimit the period of time when tropical cyclones form in the eastern Pacific Ocean. This season had an above average number of storms. There were twenty-one tropical cyclones, of which eighteen reached tropical storm strength. Four storms became hurricanes, of which none reached major hurricane strength. In the central Pacific, one hurricane and one tropical depression formed. One of the depressions crossed the dateline to become a typhoon. Systems Hurricane Adele An area of low pressure lacked strong convection until May 30, when it strengthened into Tropical Depression One-E. On May 31, the storm further intensified into Tropical Storm Adele, the first named storm and Hurricane of the season. Adele tracked westward, as it strengthened into a hurricane on June 1. It reached its peak intensity later that day. As Adele moved west, A hostile environment caused it to weaken into a Tropical Storm.

Despite that it remained away from any land masses, Adele was retired after this season for unknown reasons. Tropical Storm Blanca The tropical disturbance that became Blanca was first noted on June 8 from satellite pictures. The new disturbance would reach tropical storm strength 24 hours later. Blanca moved in a northwest direction throughout its short life, dissipating on June 12. Tropical Storm Connie Near the same location where Hurricane Adele formed two weeks earlier, a disturbance was noted on June 13. The disturbance abruptly became a tropical storm on June 17. The newly named Connie moved slowly to the northwest, reaching a peak intensity of on June 18. Connie started weakening on June 19, finally dissipating on June 21 after stalling from Clarion Island. Tropical Depression Dolores A disturbance first noted on June 19 had efficient outflow to be called a tropical depression. Satellite photos taken the same day revealed cloud structure that resembled a tropical storm forming, resulting in the system being called Dolores. The day after, no traces of a storm or of "Dolores" were found by reconnaissance. Post season analysis revealed Dolores to have only been a tropical depression. Tropical Storm Eileen A tropical
