The 1974 Pacific hurricane season officially started May 15, 1974 in the eastern Pacific, and June 1, 1974 in the central Pacific, and lasted until November 30, 1974. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeast Pacific Ocean.

With seventeen storms, this season was slightly above average. At eleven, the number of hurricanes was also above average. However, the number of major hurricanes was below average. In the central Pacific, one tropical storm formed. Very unusually, on August 26 there were five systems active: Ione, Olive, Kirsten, Lorraine, and Maggie.

[edit] Tropical Storm Aletta

On May 28, Tropical Storm Aletta formed. It recurved to the northeast and made landfall in western Mexico on May 30. Effects were minimal.

[edit] Hurricane Connie

Hurricane Connie was the first major hurricane. It took a bizarre, twisting path but never made landfall.

[edit] Hurricane Dolores

Hurricane Dolores formed on June 14. It reached category 1 intensity and made landfall on June 17.

Dolores brought heavy rains to the Acapulco area. These caused mudslides, which washed away nine people with fifteen missing. A further six people were killed when the yacht Peregrine was sunk.

On August 20, a tropical depression formed. It intensified into Tropical Storm Ione later that day. After dropping back down to a depression, it intensified again. It briefly reached Category 3 strength on August 24. Hurricane Ione is notable chiefly for its Fujiwhara interaction with Hurricane Kirsten.

Hurricane Kirsten took an erratic path. After traveling northwest for a while, it reversed direction and backtracked to almost where it started. It then reversed direction again and underwent a Fujiwhara interaction with Hurricane Ione.

[edit] Tropical Storm Lorraine

Tropical Storm Lorraine took an erratic, Z-shaped path during its life. It formed on August 23 and dissipated August 28.

[edit] Hurricane Maggie

Hurricane Maggie was the strongest storm of the season. It reached Category 4 but never threatened land.

[edit] Hurricane Norma

Hurricane Norma formed on September 9. It reached hurricane strength and made landfall the next day.

Mudslides caused by Norma's rains killed 3 people.

[edit] Hurricane Orlene

Main article: Hurricane Fifi

In Central America, Hurricane Fifi killed around 8000 people. The storm weakened to a depression and crossed into the east Pacific. The system restrengthened and was renamed Tropical Storm Orlene. Orlene hugged the coast before recurving to the northeast and made landfall shortly after reaching Category 1 intensity.

[edit] 1974 storm names

The following names were used for named storms that formed in the eastern Pacific in 1974. It is the same list as the 1970 season, except for Aletta, which replaced Adele. A storm was named Aletta for the first time this year. This is the last time this list was used to name storms, as modern naming began in 1978.
