Hurricanes Carlotta, Daniel, and Iva tracked into the Central Pacific as dissipating cyclones, where they produced a few inches of rainfall across the Hawaiian Islands.

Large waves and rough seas caused severe damage to beachfront homes and forced the rescuing of stranded boaters offshore.

In early September, the remnants of Hurricane Norman produced accumulating rain and snow across California, resulting in severe damage to its crops that totaled in excess of $300 million, in addition to killing eight people.

A small tropical disturbance, originating within the Intertropical Convergence Zone (ITCZ) across the Caribbean Sea,[4] developed in the Gulf of Tehuantepec on May 27.

[6] The system subsequently weakened as it curved north-northwest ahead of an upper-level trough over northwestern Mexico, and it made landfall about 50 mi (80 km) west of Zihuatanejo, Guerrero, at 17:30 UTC on May 31.

[4] It moved generally westward over very warm waters, and observations from satellite imagery and ships outlined the formation of a tropical depression by 00:00 UTC on June 17.

[5] The cyclone steadily lost strength and degenerated to a disturbance after 18:00 UTC on June 25 but remained a traceable entity as it moved across the Central Pacific.

The disturbance moved across the Hawaiian island chain on June 28 and continued west, ultimately merging with a cold-core low after crossing the International Date Line.

The newly named storm gathered strength over subsequent days, attaining peak winds of 65 mph (105 km/h) around 06:00 UTC on July 9.

[6] Fico, similar to the season's preceding cyclones, began as an area of disturbed weather in association with a tropical wave east of Acapulco.

Ocean waves, breaking at 15–20 ft (4.6–6.1 m) at the coast and larger values offshore, caused severe damage to beachfront homes and roads.

[9] A week later, the remnants of the storm became intertwined with a strong frontal system, producing heavy rain and winds up to 45 mph (72 km/h) to the Aleutian Islands.

[7] An area of disturbed weather spawned by a tropical wave developed southeast of Acapulco on July 11 and rapidly grew in size.

Immediately after peak, the effects of cold waters and dry air began to affect Gilma, and the storm weakened rapidly.

Further strengthening brought the system to hurricane strength by 12:00 UTC on July 23,[6] after which time a well-defined eye developed on satellite imagery.

[6] The cyclone continued west-northwest into a sharply more hostile environment of cold waters and dry air,[5] causing weakening that resulted in Hector's degeneration to a disturbance after 18:00 UTC on July 29.

[6] Very warm ocean waters facilitated the system's rapid intensification,[5] and it strengthened into Tropical Storm Iva six hours after formation before becoming a hurricane around 06:00 UTC on August 13.

Environmental conditions improved again by August 25 as Kristy regained hurricane strength, but it soon encountered cooler waters again that prompted a more concrete weakening trend.

[6] Miriam turned west-southwest and entered the Central Pacific,[5] where it intensified into a hurricane at 12:00 UTC on August 28 and reached peak winds of 90 mph (140 km/h) twelve hours later.

Norman moved west-northwest while gaining strength,[6] intensifying into a hurricane around 06:00 UTC on September 1 and developing a small eye shortly thereafter.

Subsequent recon missions found a much weakened cyclone,[5] and Norman ultimately dissipated south of San Clemente Island after 00:00 UTC on September 7.

Lingering cloud cover prevented ample drying in the wake of the storm, exacerbating agricultural losses, which were placed in excess of $300 million.

[16] The Atlantic's Hurricane Greta struck Central America and maintained its status as a tropical cyclone while crossing into the East Pacific.

The cyclone moved erratically after this point while continuing to intensify,[5] becoming a hurricane and attaining peak winds of 75 mph (121 km/h) by 00:00 UTC on September 22.

[6] Olivia eventually tracked north-northeast, moving onshore about 60 mi (97 km) east of Salina Cruz between 19:00–20:00 UTC that day;[5] the system maintained winds of 60 mph (97 km/h) at that time.

[19] Two areas of disturbed weather focused south of the Gulf of Tehuantepec on October 1, one of which with origins as a tropical wave, underwent binary interaction and merged into one larger system the next day.

[6] An aircraft reconnaissance plane intercepted the storm around this time, finding a 35 mi (56 km) elliptical eye open to the southwest.

[5] Rosa moved northwest over colder waters, transitioning to an extratropical cyclone around 06:00 UTC on October 7 and ultimately dissipating west of Baja California after twelve hours.

Although the powerful hurricane initially tracked northwest toward Hawaii, it sharply veered toward the southwest while succumbing to strong wind shear.

[6] Sergio maintained this intensity until it began to curve northward into cooler waters,[5] which caused the system to transition into an extratropical cyclone by 00:00 UTC on October 21 and dissipate to the northwest of Baja California Sur after twelve hours.
