1987 Pacific hurricane season

Overall, the season continued the general trend in the 1980s of well above-average seasons in the East Pacific. 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. There was a total of 924 storms hours and 631 hurricane hours. By comparison, the long-term averages at that time were 161 season days, 875 tropical storm hours, and 664 hurricane hours. A total of 397 advisories were issued, which was below the 1977–1987 average of 428. The hurricane hunters did not fly into any of the storms in 1987. 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. The EPHC was folded into the National Hurricane Center, which took responsibility for the basin starting in the spring of 1988. Only one tropical storm developed in June. In July, six named storms formed. Out of these storms, Hilary was the only storm to reach major hurricane status. The month of August had a total of five named storms, four of which became hurricanes. However, August did not feature any major hurricanes, though Hurricane Jova came close, peaking as a moderate Category 2. The month of September held the same number of named storms as August, with five named storms. The month also was the carrier of the strongest hurricane on record at that time (that had its intensity estimated from satellite imagery), Hurricane Max, a strong Category 4 hurricane. Hurricane Norma was a Category 1 hurricane on the Saffir–Simpson scale, which dissipated to the south of the Baja California Peninsula. The month of October featured only two tropical cyclones. The first system, Ramon, was a Category 4 hurricane. Very few cyclones this season impacted land. The only landfalling hurricane of the year, Hurricane Eugene was responsible for significantly damaging about 15 sq. mi of fruit crop, where damage estimated were at $2.6 million (1987 USD) In all, damage totaled to about $142 million. The Pacific Decadal Oscillation (PDO) was in a warm phase during this time period, with estimates placing the PDO at +. == Systems ==

Tropical Storm Adrian On June 7, a tropical depression formed southeast of Acapulco, Mexico. It strengthened into a tropical storm immediately thereafter. After peaking with maximum sustained winds of on June 8, Adrian slowly weakened. It fell to tropical depression status on June 9 and dissipated later that day. During its life, Adrian paralleled the Mexican shoreline far offshore before looping counter-clockwise over its path when it was a depression. Tropical Storm Beatriz On July 3, a tropical depression formed south of Cabo San Lucas. It strengthened into a tropical storm later that day. Beatriz slowly strengthened and moved generally northwest as it stayed far offshore. On July 5, Beatriz reached its peak wind speed of . It weakened thereafter, falling to a depression on July 6 and dissipating the next day. Tropical Storm Calvin A tropical depression formed south of Mexico on July 5 and immediately strengthened into a tropical storm the next day. Calvin headed generally east. On July 8, as a strong tropical storm. It then gradually weakened, falling to a depression on July 9 and dissipated the next day while located southwest of Cabo San Lucas. Tropical Storm Dora A tropical depression that had organized on July 15 while located south of Cabo San Lucas. The depression strengthened into a tropical storm that same day while located around west of Acapulco. Dora headed west-northwest and slowly strengthened. It reached its peak winds of on July 17. It then steadily weakened, becoming a depression two days later. Dora dissipated on July 20 while located west of Cabo San Lucas. Hurricane Eugene A tropical disturbance developed into a tropical depression on July 22 near the coast of Mexico. It initially headed westward and strengthened into a tropical storm the same day it formed. It strengthened into a hurricane, the first of the season, on July 24 as an upper-level cyclone pulled the system north. After peaking as a low-end Category 2 hurricane on July 25, land interaction weakened the hurricane to Category 1 as it made landfall west of Manzanillo. The rough topography weakened Eugene, and the hurricane was only a depression when it emerged into the Gulf of California. It promptly dissipated on July 26. Hurricane Eugene caused extremely heavy rain in coastal parts of Mexico. The highest rain was 20.68 inches at Aquila, Michoacán. Over 5,000 people were displaced. In Manzanillo alone, at least 60 people were rendered homeless. Most of the damage was the scattering of debris and mud. Six people were injured, and a man in Venustiano Carrazano was killed when a palm tree was blown over. In all, three fatalities were reported. Additionally, damage to eight beach houses totaled to $120,000. Total crop damage reached $142 million (1987 USD); Hurricane Hilary A tropical wave moved through Central America on July 30 and July 31. 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. Thunderstorm activity increased considerably after 00:00 UTC on July 31. A tropical depression formed at 18:00 UTC on July 31 while located south of Cabo San Lucas. Tropical Storm Irwin A tropical depression formed on August 3 over south of Manzanillo. The depression quickly intensified into a tropical storm. Irwin fluctuated in strength as it closely paralleled the coast of Mexico. On August 6, Irwin reached its maximum winds of ; it maintained that velocity for over two days. During August 8, Irwin turned nearly due west and headed out to sea. Irwin weakened to a tropical depression on August 9 and immediately dissipated. Forecasters at one point in time noted the possibility of the storm impacting California. In addition, the storm produced heavy rainfall in Mexico, causing $2.1 million in damage. Although many businesses and homes received damage, no deaths were reported. Tropical Storm Oka A disturbance in the Intertropical Convergence Zone organized into Tropical Depression One-C on August 26. Twelve hours later, it was upgraded to a tropical storm and named Oka, which is Hawaiian for Oscar. Oka slowly moved west-northwest and reached its peak wind speed of 60 mph (95 kmh) on August 27. The next day, a nearby trough caused wind shear, which weakened Oka to a depression on August 29 and subsequently destroyed it. One woman was injured by a lightning strike. Hurricane Max A tropical disturbance left Central America on September 8. At 1200 UTC on September 9, a tropical depression formed over the warm waters south of the Gulf of Tehuantepec. Dvorak classifications—used to estimate a tropical cyclone's intensity—were at T7.0/, the highest ever recorded in the basin, Max maintained its intensity for 24 hours. However, the storm crossed the isotherm and began to weaken rapidly. The hurricane's track then shifted north for a time, before turning to the west on September 15. That same day, it weakened to a tropical storm. The tropical cyclone dissipated at 1200 UTC September 16 while located north-northeast of Cabo San Lucas. The hurricane was predicted to cause waves in Southern California, though Max was well past its peak at that time. The remnants ultimately caused rainfall and thunderstorms in California on September 22 and September 23. The rainfall totaled to at Lindbergh Field, and at Lemon Grove. There were numerous power outages, small fires, some road flooding, and some property damage. In San Diego and southern Orange County, 200,000 homes and business lost power, but the power was quickly restored. However, there are no reports of damage or flooding in Baja California from the storm; the area the tropical cyclone struck was sparsely populated. Hurricane/Typhoon Peke caused no damages or deaths. and 1986's Typhoon Georgette. Tropical Storm Pilar A tropical depression formed on September 30 while located south of the Baja California Peninsula. It headed north and peaked as a minimal tropical storm on October 1. After being a tropical storm for a mere six hours, Pilar weakened to a depression and dissipated that same day. It never made landfall, dissipating just south of the southern tip of the Baja California Peninsula. It was a tropical cyclone for a total of 24 hours. The system caused no known damage on land, but Pilar dropped heavy precipitation on Baja California Sur from 1200 UTC on September 30 until 0000 UTC October 2. An observer station reported of rainfall. This was the most rainfall the weather station had ever recorded since its founding in 1969. resulting in street flooding. Two people perished in separate traffic accidents. In Los Angeles, three more people perished in separate traffic incidents. Heavy rains extended west and was also reported in Hemet in Riverside County, The rains helped dissolve a week-long forest fire 16,000 acre (65,000,000 m2) on Mt. Palomar. The tropical moisture also helped end a 37-day dry spell at Salt Lake City, marking the longest time the city went without rain since 1964. Nationwide, Ramon killed five people, all due to road-related incidents. Tropical Storm Selma On October 27, a tropical depression formed and headed northwest, gradually re-curving north. It intensified into a tropical storm on October 28. Selma maintained that strength until the next day, when it weakened to a depression. Selma's re-curving continued, and on October 29, it again intensified into a tropical storm. Without further strengthening, it weakened into a tropical depression, headed north northeast, and dissipated on October 31 about east of the southern tip of Baja California. Tropical depressions On June 10, a weak tropical depression, the second of the season, developed. It moved very little and did not affect land. It dissipated on 1200 UTC June 12. however, this storm was not included into CPHC database. As it entered into western Pacific, it strengthened as a tropical storm and received the name Wynne. The final tropical cyclone developed at 1800 UTC November 24 around southwest of Baja California Sur. A very weak cyclone, the depression dissipated on November 25, ending the above-average season. == Storm names ==

The following list of names was used for named storms that formed in the North Pacific Ocean east of 140°W in 1987. This is essentially the same list used for the 1981 season, though the rotating lists went only to the "W" name at the time. Storms were named Pilar and Ramon for the first time in 1987; the name Selma had been used previously used in the old four-year lists. For storms that form in the North Pacific from 140°W to the International Date Line, the names come from a series of four rotating lists. Names are used one after the other without regard to year, and when the bottom of one list is reached, the next named storm receives the name at the top of the next list. It was replaced with Kenneth for the 1993 season. ==Season effects==
