The 1984 Pacific hurricane season officially started May 15, 1984 in the eastern Pacific, and June 1, 1984 in the central Pacific, and lasted until November 30, 1984. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.

[edit] Activity
There were 18 tropical storms in the eastern Pacific this season. Twelve became hurricanes. Of those, six became major hurricanes by reaching Category 3 intensity or higher on the Saffir-Simpson Hurricane Scale. In the central Pacific, there was a major hurricane and two tropical storms. There was at least one tropical depression that did not strengthen into a storm.
[edit] Hurricane Boris
Boris was a minimal hurricane whose path included a loop, a rarity in this basin. It had no effect on land.
[edit] Hurricane Douglas
Douglas was the strongest storm of the season. Its remnants brought rain to Maui and the Big Island.
[edit] Hurricane Genevieve
Genevieve made approached Baja California Sur, but dissipated without making landfall.
[edit] Hurricane Keli
Hurricane Keli was a major hurricane that threatened Johnston Atoll enough to prompt an evacuation. However, intense shear disintegrated the cyclone. There was no damage.
[edit] Tropical Storm Lala
Lala formed from Tropical Depression Fourteen-E, which moved in from the east.
[edit] Tropical Storm Moke
Moke had uncertain beginnings, as it developed from a cold-core low that eventually became a tropical storm just east of the dateline. It passed close to Kure Atoll, encountered shear, and lost tropical characteristics.
[edit] Hurricane Marie
Hurricane Marie dissipated off the coast of Baja California. Its remnants recurved and brought minor levels of rain to California.
[edit] Hurricane Norbert
Norbert was a hurricane that took a truly bizarre path. It drifted south, then east, then north, then west, and then south again as it traced out a spiral around its place of cyclogenesis. Norbert then turned east again before accelerating to the northwest. It recurved slightly and it dissipated before making landfall in Baja California.
[edit] Hurricane Odile
Odile took an erratic path before making landfall near Acapulco on September 22. It dissipated the next day.
[edit] Hurricane Polo
As a tropical depression, Polo made landfall in the extreme southern part of the Baja California Peninsula on October 3.

A tropical depression formed on October 7, several hundred miles south of Mexico. It was upgraded to Tropical Storm Rachel on October 9, as it continued westward into the open waters of the Pacific Ocean. Rachel was downgraded to a tropical depression on October 11, as it began to turn northwest. The depression then dissipated in open waters on October 16.[1]
[edit] 1984 storm names
The following names were used for named storms that formed in the eastern Pacific in 1984. No names were retired, so it was used again in the 1990 season. This was the first time these names had been used since the modern naming system began. Names that were not assigned are marked in gray.
