These dates conventionally delimit the period of each year when the vast majority of tropical cyclones form in the northeastern Pacific Ocean.

Tropical Storm Pilar and Hurricane Norma also came close to land, with the former producing record rain in Baja California Sur.

The remnants of Hurricanes Ramon and Norma caused rain in the Continental United States, with the former responsible for five traffic-related deaths.

[4] The season lasted a total 171 days beginning with the formation of Adrian and early June and the dissipation of Tropical Depression Twenty on November 25.

[6] 1987 was the last season that the Eastern Pacific Hurricane Center in Redwood City was responsible for forecasting in this basin, a task it had performed since circa 1972.

It then gradually weakened, falling to a depression on July 9 and dissipated the next day while located 440 mi (710 km) southwest of Cabo San Lucas.

The weather service issued navigation warnings for three coastal states and ships were urged to maintain contact with officials.

[20] Total crop damage reached $142 million (1987 USD);[9] In the aftermath of the storm, the navy and army and local government devised a cleanup plan.

Fernanda strengthened and reached its peak strength near hurricane status on July 26, the same day it crossed 140°W and entered the central north Pacific.

Steered by a large deep-layer ridge that extended as far southwest as Hawaii and as far northeast as Oklahoma, the wave moved steadily west-northwest.

A tropical depression formed at 18:00 UTC on July 31 while located 775 mi (1,245 km) south of Cabo San Lucas.

It was in a moderately declining state when it crossed 140°W and entered the Central Pacific Hurricane Center's area of responsibility.

The next day, a nearby trough caused wind shear, which weakened Oka to a depression on August 29 and subsequently destroyed it.

It remained south of the Mexican coast in an area of warm sea surface temperatures, and at 1800 UTC August 29, Tropical Depression Fifteen formed.

It edged in a more westerly direction for a day before resuming its northwesterly path, and reached hurricane intensity on 0600 UTC September 1.

[3] At its strongest on September 1 based on intensity estimates via Dvorak classifications, Hurricane Lidia had a wind speed of 85 mph (135 km/h).

[5] While located 935 mi (1,505 km) from Cabo San Lucas, the depression intensified into a tropical storm and was named Max.

The tropical cyclone dissipated at 1200 UTC September 16 while located 865 mi (1,390 km) north-northeast of Cabo San Lucas.

However, Norma remained offshore due weak southwesterly flow from a cutoff low located west of Baja California Sur.

Tropical Depression Norma dissipated a mere 95 mi (155 km) south of the Baja California Peninsula; it never made landfall.

[3] Prior to the remains of Hurricane Norma's arrival in the Southwestern United States, forecasters were anticipating cloudy skies over San Diego.

[31] However, there are no reports of damage or flooding in Baja California from the storm; the area the tropical cyclone struck was sparsely populated.

[3] That day, it began accelerating to the west as it lost strength due to increased wind shear and decreasing ocean temperature.

[3] An area of disturbed weather southwest of Hawaii gathered enough convection and a closed circulation to become Tropical Depression Two-C on September 21.

Peke continued heading north and shortly after weakening into a Category 1 hurricane, it turned to the northwest and crossed the dateline.

Peke's remnants continued drifting erratically for over three days, first heading east, then northwest, and then southeast, at which time they were finally unidentifiable.

[3] After peaking, Ramon turned to the northwest due to interaction with subtropical jetstream winds and rapidly weakened over cooler sea surface temperatures.

[38] Heavy rains extended west and was also reported in Hemet in Riverside County,[38] where three people were also injured during a car accident.

Without further strengthening, it weakened into a tropical depression, headed north northeast, and dissipated on October 31 about 880 mi (1,415 km) east of the southern tip of Baja California.

[43] The final tropical cyclone developed at 1800 UTC November 24 around 1,000 mi (1,600 km) southwest of Baja California Sur.
