Celeste was the strongest storm of the season, and caused heavy damage to Johnston Atoll.

Hurricane Joanne brought gale-force winds to the Continental United States and caused flooding in Arizona and northern Mexico, which killed one person.

These dates conventionally delimit the period of time when tropical cyclones form in the east Pacific Ocean.

In the northeastern Pacific (from the North American coastline to 140°W)[citation needed], one storm formed in June, one in July, six in August, two in September, and one in November.

[1] Of this season's fourteen named tropical cyclones, twelve formed in the eastern Pacific and two in the central.

Celeste's Category 4 winds and central pressure of 940 millibars (940 hPa) made it the most intense cyclone of the season.

It was spotted by a hurricane hunter and was reached and towed to safety by another ship, the Vishea Trith, and later on, the USCGC Mellon.

High waves also pounded the Puna, Kau, and South Kona Coasts of the Big Island.

[4] Shortly after crossing the basin boundary on a path directly towards the Hawaiian Islands, Diana weakened into a tropical storm.

[5] Diana threatened the Hawaiian Islands enough to warrant the issuance of a tropical storm warning.

Although it never made landfall, Diana dumped very heavy rain on the Big Island, though without flooding; the highest total was 10 inches (250 mm) somewhere northeast of Hilo.

Hurricane Estelle spent its entire life well away from inhabited land, and consequently caused no deaths or damage.

A flash flood on Waipio Stream in the Big Island's Kohala Mountains may have been due to Fernanda.

Gwen moved generally northwest, paralleling the coast of Mexico, and intensified into a hurricane on August 24.

On August 19, Iva got caught in the trade winds, headed westwards out to sea, and promptly weakened into a depression.

[4] A northwestward-moving disturbance in the Intertropical Convergence Zone developed into a tropical depression on September 24 and a storm two days later.

Tropical Storm June passed southwest of Johnston Island on September 27, but was too feeble to cause damage, only bringing gusty breezes and some rain.

While accelerating in that direction, Joanne made landfall near Laguna Chapala on the Baja California Peninsula as a tropical storm.

[4] Joanne managed to retain a closed circulation and bring tropical storm force winds to Arizona, the first recorded time that had happened.

[4] Joanne is one of only four known Pacific hurricanes to bring gale-force winds to the Continental United States, and was the first since the 1939 California tropical storm.

[13] A young man in Phoenix was electrocuted and killed when he attempted to remove a downed power line from his car.

[3] On October 18, a vortex in the Intertropical Convergence Zone was determined to be a tropical storm through the use of satellite pictures.

[4] On October 16, the northern hemisphere component of a "cyclone twin" was classified by JTWC as a tropical depression while located near 7.0°N 179°W, just within the central Pacific basin.

[5][16] After crossing the International Date Line, it intensified into Tropical Storm Olga of the 1972 Pacific typhoon season.

[5] An area of enhanced convection in the ITCZ close to the equator formed into a tropical depression on November 11.

Ruby then abruptly turned west and crossed the dateline, briefly reaching hurricane status.

It then steadily weakened as it headed west northwest, and wind shear destroyed the cyclone on November 20 when it was east of the Northern Marianas Islands.

Of note is the fact that on November 17, Ruby had a central pressure of 983 mb (983 hPa), which is high for a 100-knot typhoon.

At the time, storm names within this region were assigned by the Joint Typhoon Warning Center on Guam.

It includes their name, duration, peak classification and intensities, areas affected, damage, and death totals.
