The 1962 Pacific hurricane season was a moderately active Pacific hurricane season that included two hurricane landfalls. The first, Hurricane Valerie, struck northwestern Mexico in June. The other, Hurricane Doreen, hit further to the north of Valerie in October. The most impacting storm of the season was Tropical Storm Claudia, after its remnants dropped heavy rainfall in portions of Arizona. The rainfall left damaging flooding across rivers and towns.

Storms


Hurricane Valerie

Category 1 hurricane (SSHS)
Duration June 24 – June 26
Intensity 85 mph (140 km/h) (1-min),  Unknown

The first tropical cyclone of the season – Hurricane Valerie – was first observed on June 24, about 245 mi (400 km) west of Acapulco, Guerrero.[1] It moved northwestward along the coast, producing high seas and strong winds in southwestern Mexico.[2] Valerie was estimated to have attained peak winds of 85 mph (140 km/h). It turned to the northeast and struck near Mazatlán on June 25, dissipating early the next day.[1]

Tropical Storm Willa

On July 8, Tropical Storm Willa developed south of the Baja California peninsula. It maintained a west-northwestward track throughout its duration, remaining a minimal tropical storm. On July 10, the storm dissipated.[1]

Tropical Storm Ava

In the middle of August, a tropical storm formed off the southwest coast of Mexico. Given the name Ava, it tracked to the northwest before turning more to the north. It dissipated on August 20.[1]

Unnamed August tropical storm

As the previous storm was dissipating, another tropical storm developed to its west. Lasting only two days, it dissipated on August 22 about halfway between Hawaii and the west coast of Mexico.[1]

Hurricane "C"

On August 24, satellite imagery indicated a hurricane with a defined eye was located over the central Pacific Ocean. It slowly weakened as it moved over lukewarm waters, and deteriorated more rapidly after wind shear increased. By August 28, the system consisted of a circulation with only weak associated convection. It weakened to a tropical depression on August 30, although it remained a tropical cyclone until September 2. At that time it was last observed about 200 mi (320 km) south of Hilo, Hawaii.[3][1]

Tropical Storm Bernice

Tropical storm (SSHS)
Duration September 2 – September 6
Intensity 50 mph (85 km/h) (1-min),  Unknown

A tropical storm named Bernice developed on September 2 west of Jalisco. After moving northwestward for two days, the storm turned to the north, striking Baja California on September 6 before dissipating.[1]

Tropical Storm Claudia

Tropical storm (SSHS)
Duration September 20 – September 24
Intensity 50 mph (85 km/h) (1-min),  Unknown

Later in the month, another storm similar to Bernice existed. Tropical Storm Claudia formed on September 20 to the southwest of Acapulco. It maintained a general northwest movement for its duration. On September 23, Claudia crossed over the western portion of the Baja California peninsula, moved over water, and again struck the peninsula before dissipating.[1]

The remnant moisture caused severe flash floods in the vicinity of Tucson, with 5 to 7 inches (130 to 180 mm) of precipitation falling over the headwaters of the Santa Rosa, Jackrabbit, and Brawley Washes during a 14–15 hour period.[4] Over 7 inches (180 mm) of rainfall also fell near the Arizona-Sonora Desert Museum.[5] The ensuing flood of the Santa Cruz River and its tributaries produced a path of destruction about 100 miles (160 km) long and up to 8 miles (13 km) wide. Santa Rosa Wash conveyed 53,100 cubic feet per second (1,500 m3/s) at its peak; Los Robles Wash carried up to 32,600 cu ft/s (920 m3/s), while the Santa Cruz River proper peaked at 9,200 cu ft/s (260 m3/s). The washes and rivers reached depths of up to 20 feet (6.1 m), and overflowed its banks in places by 1 to 6 feet (0.30 to 1.8 m).[4] Flooding from the storm inundated the towns of Marana and Sells, both in Pima County.[5] Helicopters rescued 27 families from Fort Huachuca. There was one indirect death related to the flooding, due to an ambulance not being able to reach an elderly woman. The flooding also killed many cattle,[6] and damage in Pima and Pinal counties exceeded $11 million (1962 USD),[4] much of it from crop damage.[7] The flooding prompted a disaster declaration by former governor Paul Fannin, which provided funds for the affected people.[8]

Unnamed September tropical storm

On September 26, a tropical storm developed off the southwest coast of Mexico. The storm moved to the west-northwest for several days, dissipating on September 30.[1]

September and October Central Pacific tropical cyclones

In September and October, satellite imagery indicated that there were five tropical storms in the central Pacific Ocean. The first, designated Tropical Storm "R", passed about 200 mi (320 km) north of Palmyra Island on September 28. It represented about 1% of storms in the basin to directly affect the island, after it produced westerly winds there. Tropical Storm "T" existed on September 29 without affecting land. Similarly, Tropical Storm "X" existed on October 2 over open Pacific waters. The next day, Tropical Storm "Z" passed near Johnston Island during the Operation Dominic I and II nuclear tests, although no impact was reported. Lastly, satellite imagery indicated Tropical Storm "A" on October 27 to the northeast of Palmyra Island.[3]

Hurricane Doreen

Category 1 hurricane (SSHS)
Duration October 1 – October 5
Intensity 85 mph (140 km/h) (1-min),  Unknown

The last storm of the season was Hurricane Doreen, which formed on October 1 off the southwest Mexican coast. It moved northwestward before curving to the north, although later it turned again to the northwest. Doreen was estimated to have attained peak winds of 85 mph (140 km/h). On October 4, Doreen made its closest approach to the southern tip of the Baja California peninsula as it began a motion to the northeast. Later that day, the hurricane moved over southern Sonora before dissipating on October 5.[1]

Tropical depressions

There were two non-developing tropical depressions during the season.

Surface observations and satellite imagery indicated the formation of a tropical depression about 275 mi (443 km) north of Palymra Island on July 29. It moved west-northwestward without developing further, and eventually dissipated on August 2 over the central Pacific.[3]

On August 31, the Joint Hurricane Warning Center named a tropical depression in the Central Pacific basin as Tropical Depression 63, following the West Pacific's numbering. The advisories were discontinued 275 nautical miles (509 km) from the South Point of Big Island, where it was no longer considered a threat to shipping lanes or any land masses.[3]
