The '''1986 Pacific hurricane season''' officially started [[May 15]], [[1986]] in the eastern Pacific, and [[June 1]], [[1986]] in the central Pacific, and lasted until [[November 30]], [[1986]]. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern [[Pacific Ocean]].
== Seasonal activity ==
Activity in the Eastern Pacific basin was above average. There were 25 tropical depressions, one short of the record set in 1982.<ref name="1986PHS"/> There was only one Central Pacific-born cyclone, One-C.<ref name="CPHC86"/> Six other cyclones, Estelle, Frank, Georgette, Depression Ten-E, Lester and Orlene all entered the Central from the East Pacific.<ref name="CPHC86"/>
==Storms==
The number of storms this season was slightly above average. There were seventeen tropical cyclones reaching tropical storm strength, and six hurricanes. However, the number of major hurricanes was below average with three.

Agatha made an abrupt change in direction, going towards the north. Agatha strengthened into a hurricane on [[May 25]] near the coast of [[Mexico]], peaking at 75 mph (115 km/h). Agatha changed direction again, towards the southeast. Agatha quickly weakened into a tropical depression, but regained strength on [[May 28]] and [[May 29]], until it dissipated that day.<ref name="1986PHS"/>
Rainfall spread around both the Mexican coasts, peaking at 10¾ inches at Xicotepec de Juarez.<ref name="AgathaRain">{{

Tropical Depression Two-E was a short-lived cyclone, a lifetime of only 12 hours. The depression began as a disturbance on [[May 30]] in the eastern [[Gulf of Tehuantepec]]. The disturbance became close to being stationary when it was upgraded to Tropical Depression Two-E on [[May 31]]. The depression began to weaken six hours later and the final advisory by the EPHC was released on [[June 1]].<ref name="1986PHS"/> Most of Mexico was poured on, with three inches (76 mm) totaling on [[Yucatán Peninsula]]. The worst rain was in central Mexico, where over {{convert|15|in|mm}} rain fell, peaked at 18.63 inches in Tenosique. The rest of Mexico was hit by 1-3 inches of rainfall.<ref name="2ERain">{{

Tropical Storm Blas formed on [[June 17]] from a tropical disturbance that had originated the day before in the ITCZ.<ref name="1986PHS"/> The disturbance moved at {{convert|13|mi/h|km/h|0|abbr=on}} below a weak upper-level high, strengthening into the third tropical depression of the 1986 season. Winds reached 40 mph (60 km/h) on [[June 18]], strengthening Tropical Depression Three-E into Tropical Storm Blas. It kept that strength for only 6 hours, weakening into a depression again as it moved into weaker waters. The EPHC ceased advisories on [[June 19]] after Blas' convection dissipated. Blas did not affect land in any way.

Five days after Tropical Storm Blas dissipated, a tropical disturbance formed south of the Gulf of Tehuantepec on [[June 24]].<ref name="1986PHS"/> Later that day, circulation had organized enough to upgrade the disturbance into Tropical Depression Four-E. Winds reached {{convert|40|mi/h|km/h|-1|abbr=on}}, upgrading the system into Tropical Storm Celia on [[June 26]]. Celia, off the coast of Mexico, strengthened into Hurricane Celia at 1800 [[UTC]] [[June 27]]. An eye became evident and Celia reached its peak intensity of 90 mph (145 km/h) on [[June 28]] at 1600 [[UTC]]. Celia moved into much cooler water, weakening the storm rapidly. By [[June 30]], Celia had become a tropical depression. The Eastern Pacific Hurricane Center released its final advisory on Celia at 1800 [[UTC]] that day as Celia was dissipating. During its life, Celia had passed by [[Socorro Island]], however no damage was reported.<ref name="1986PHS"/>

Tropical Storm Darby, the fifth tropical cyclone of the season, formed as a tropical disturbance on [[July 2]].<ref name="1986PHS"/> Moving at about {{convert|13|mi/h|km/h|0|abbr=on}}, the disturbance entered warmer water and strengthening rapidly. The disturbance became Tropical Depression Five-E at 1800 UTC [[July 3]]. Depression Five-E turned to the west-northwestward and strengthened into Tropical Storm Darby on [[July 5]]. Darby peaked at 40 mph (60 mph). The stormed continued northwest for about 6 hours, when it reached 25 °C waters and began to weaken. Clouds spread from [[Arizona]] and parts of [[California]] on [[July 6]], soon before dissipating the 7th.<ref name="1986PHS"/>

| lowest pressure=Unknown
}}
At midday on [[July 16]], a tropical depression formed, and within 12 hours it strengthened into a tropical storm.<ref name="1986PHS"/> On [[July 18]], Estelle intensified into a hurricane, and located in a favorable environment, Estelle continued strengthening to become the first major hurricane of the season on [[July 20]]. The hurricane entered the [[Central Pacific Hurricane Center|CPHC]]'s Area of Responsibility near its peak strength of {{convert|135|mi/h|km/h|0|abbr=on}}. Estelle's forward motion increased to close to {{convert|20|kn|km/h|0}}, resulting in the path of a potential landfall on the [[Big Island of Hawaii|Big Island]]. Due to a shearing environment from a [[trough (meteorology)|trough]], Estelle weakened as it continued approaching [[Hawaii]]. A possible re-curve never materialized, and the cyclone continued its path towards the [[Hawaiian Islands]]. The hurricane veered to west and passed south of the islands. Estelle weakened to a tropical storm on [[July 23]], and on the 25th it weakened to a depression. The storm dissipated two days later.
Due to its rapid motion, Estelle kept pace with a large swell of water that it generated. In combination with a high spring tide and peripheral winds generated by Estelle, huge waves crashed on the shores of the Big Island on the afternoon of [[July 22]]. The high waves washed away five beachfront homes and severely damaged dozens of others in [[Vacation Land, Hawaii|Vacation Land]]. The total damage was around $2 million (1986 USD). On [[Maui]], waves washed away a [[dirt road]] on the eastern part of the island between [[Kipahulu, Hawaii|Kipahulu]] and [[Kaupo, Hawaii|Kaupo]]. After Estelle passed by the islands, moisture related to the tropical cyclone caused heavy rainfall in the [[Kau, Hawaii|Ka'u]] and [[Puna, Hawaii|Puna]] districts on the Big Island. After Estelle dissipated, its moisture became entrapped in a trough over the islands, causing significant rainfall and thunderstorms over the archipelago. The only deaths reported were two drowning on [[Oahu]] that occurred on [[July 23]], due to rough surf caused by Estelle.
Estelle was a well-observed storm, with [[Reconnaissance Aircraft]] flying into the hurricane to provide a fix on its location. It also passed near [[NOAA]] [[weather buoy|Buoy 51004]] on [[July 22]], providing valuable meteorological data for its future path.

Tropical Depression Seven-E began as a giant area of thunderstorms near the large Hurricane Estelle. It strengthened into Tropical Depression 7-E on [[July 17]]. Moving at about 12-13 mph, Depression Seven-E failed to intensify and peaked at 30 mph (50 km/h). Cool temperatures and the close distance to Hurricane Estelle were causes of Depression Seven-E to dissipate late on [[July 18]].

Hurricane Frank began on [[July 24]] near [[Latitude]]:11.300 / [[Longitude]]:-96.100. Winds were 29 mph (46 km/h). Hurricane Frank continued towards Latitude:22.100 / Longitude:-143.400 ending with winds of 35 mph (56 km/h) on [[August 3]]. Starting from being a [[Tropical Depression]], Hurricane Frank became a [[Hurricane]] on [[July 30]] with winds over 87 mph (140 km/h). The minimum pressure is unknown.

}}
Tropical Depression TEN-E had been a steady state tropical depression for about 3 days before moving into the Central Pacific. Tropical Depression TEN-E crossed 140 °W near 12 °N on [[July 27]] at about 1000Z. A slow weakening began as the depression continued to move west at near 30 mph (45 km/h). By 301800Z near 12 °N near 148 °W, it had become poorly organized and on [[July 29]] the final advisory was issued.
<div style="clear:both;"></div>
===Tropical Depression One-C===

| lowest pressure=Unknown
}}
Tropical Depression ONE-C was tracked westward along 11 °N at a fairly rapid forward speed of 35 mph (56 km/h) on [[July 27]]. The data are sketchy, but it is possible that ONE-C was formed from the remnants of [[Tropical Depression EIGHT-E]], which had dissipated a few days earlier well to the east of 140 °E. Several radio reports from ship ABQJ on [[July 27]] and [[July 28]] were helpful in locating the depression's center. Tropical Depression ONE-C failed to develop past the depression stage. It passed well south of the [[Hawaiian Islands]] on [[July 28]] with no noticeable effects on the [[Islands]]' weather. At 280000Z, it was dissipating to the southwest of the Hawaiian Islands and the final advisory was issued.

| highest winds=40 [[miles per hour|mph]] (65 [[kilometres per hour|km/h]])
| lowest pressure=Unknown
}}
On [[August 3]], a tropical depression organized in the open ocean. Twelve hours later, it strengthened into Tropical Storm Georgette before weakening to a depression 6 hours later. It then accelerated to a very rapid speed of 20-39 [[knot (speed)|knots]]. Due to its fast speed, Georgette couldn't maintain a closed circulation, and the tropical storm degenerated into a non-cyclonic disturbance. The disturbance kept up its rapid forward motion, crossed the dateline, and entered the western Pacific.
Five days later, Georgette reformed into a depression. As was customary, it kept its name. It eventually strengthened into a minimal typhoon. It began a [[Fujiwhara interaction]] with the larger and stronger [[1986 Pacific typhoon season#Typhoons Georgette and Tip|Typhoon Tip]] and was eventually absorbed by it.
Georgette is properly a typhoon because it never strengthened into a hurricane east of the dateline. The dissipation of a storm in the central Pacific and regeneration in the western Pacific is extremely uncommon. The next time this happened was with Enrique in 1991.

One of four storms to have major affect on the land, Newton formed as a tropical disturbance off the Nicaraguan coast.<ref name="1986PHS"/> The disturbance becomes the twentieth depression of the 1986 season on [[September 18]]. Intensification was slow as Tropical Depression Twenty-E did not reach storm status until [[September 20]]. Now Tropical Storm Newton, the cyclone began to parallel the Mexican coast. Newton strengthened into a hurricane on [[September 21]]. Newton peaked at about 90 mph (145 km/h) and a minimal pressure of 984 mb. On [[September 22]], Newton slammed [[Cabo San Lucas]] and moved inland into [[New Mexico]]. Newton dissipated on [[September 23]]. However, the remnants of Newton continued across the [[United States]] and entered the [[Atlantic Ocean]] on [[September 26]].<ref name="1986PHS"/>
Flash flood warnings were issued by the National Weather Service as Newton, along with a front over the [[Great Plains]], was predicted to cause heavy rains over New Mexico and western Texas.<ref name="NewtonNews2">{{

The twenty-first cyclone of the season formed from a tropical disturbance in the ITCZ.<ref name="1986PHS"/> The disturbance moved at about {{convert|10|mi/h|km/h|-1|abbr=on}}. The disturbance was declared Tropical Depression 21-E at 600 [[UTC]] [[September 19]]. However the depression lasted a short time, only six hours, when it dissipated, possibly due to the close distance between it and Tropical Storm Madeline.<ref name="1986PHS"/>

The 22nd cyclone of the 1986 season formed as a tropical disturbance on [[September 19]].<ref name="1986PHS"/> The disturbance was quasi-stationary for about 30 hours, when it strengthened into Tropical Depression 22-E on [[September 21]]. Depression 22E strengthened at a very rapid rate, become Tropical Storm Orlene 12 hours later and Hurricane Orlene 9 hours after that. The next advisory would be released by the [[Central Pacific Hurricane Center]] in [[Hawaii]] as it moved past the 140°W border line.<ref name="1986PHS"/>
The Central Pacific Hurricane Center's first advisory had winds at 75 mph (115 km/h). Orlene gained more strength, peaking at 80 mph (130 km/h). Orlene moved into area of strong wind shear, causing rapid weakening. Orlene weakened into a tropical depression on [[September 24]] and advisories ceased soon after. Orlene did not affect land in anyway.<ref name="CPHC86">{{

The 23rd cyclone of the 1986 season formed as a tropical disturbance on [[September 27]].<ref name="1986PHS"/> The disturbance strengthened into Tropical Depression Twenty-Three-E that night (0000 [[UTC]] [[September 28]]). Tropical Depression 23-E moved northwestward and began to veer around due to an upper-level trough near northern [[Mexico]]. At 0000 [[UTC]] [[September 30]], the depression became Tropical Storm Paine, southwest of Acapulco. 21 hours later, a [[NOAA]] recon flight found winds of 90 mph (145 km/h), upgrading Paine into hurricane. Paine peaked as a Category 2 hurricane on [[October 1]] as it headed towards the [[Sea of Cortez]]. Paine turned northwestward and crossed the coast at San Jose with winds of 100 mph (160 km/h). Paine weakened as it moved over land going through Mexico and then entering the United States. Paine dissipated over land on [[October 2]]. The system continued however, dissipating on [[October 4]] over [[Lake Michigan]].<ref name="1986PHS"/><ref name="PaineRain"/>
Rainfall from Paine was significant in Mexico and the United States. One to three inches (76 mm) of rain fell in Cabo San Lucas with rains around the Mexican mainland peaking at 12 inches in [[Acapulco]]. [[Fort Scott, Kansas]] reported the peak total in the U.S. with {{convert|11.35|in|mm}}. Flooding was reported due to recent rains, particularly near [[Oklahoma City]].<ref name="PaineRain">{{

Tropical Depression 24 originated as a tropical disturbance which moved westward offshore [[Nicaragua]]. During the early afternoon of the 15th, ship reports indicated the formation of a tropical depression near 10.2N 92.7W. The cyclone moved at a quick pace to the west- northwest south of a warm-core ridge.<ref name="1986PHS"/> Early on the morning of the 16th, Roslyn became a tropical storm. By the morning of the 17th, it had developed into a hurricane south of [[Acapulco]]. A vigorous upper trough was deepening offshore [[Baja California]], and Roslyn began to re-curve within a few hundred miles of [[Manzanillo, Colima|Manzanillo]]. Striking [[Mazatlán]] as a marginal hurricane on the 20th, its upper level portion moved northeast thereafter spurring cycle-genesis in the western Gulf of Mexico along the frontal zone, causing heavy rains along the Middle Texas coast. The surface low occluded and moved northward through the Mississippi Valley, spreading light to moderate rains
along its path. However, its upper level portion continued moving eastward, spreading rains across the Deep South.<ref name="RoslynRain">{{

Tropical Depression 25-E was the final tropical depression of the 1986 season.<ref name="1986PHS"/> It formed on [[October 22]] at 1800 [[UTC]] near the 140°W latitude line, which splits the Eastern and Central Pacific basins. A low pressure trough extended a large area, making development very unlikely. 30 hours after forming, the stationary storm dissipated.

==1986 storm names==
The following names were used for named storms that formed in the eastern Pacific in 1986. No names were retired, so it was used again in the [[1992 Pacific hurricane season|1992 season]]. This is the same list used for the [[1980 Pacific hurricane season|1980 season]]. Storms were named Orlene, Paine, and Roslyn for the first time in 1986, although Orlene had been used on the old four-year lists. No central Pacific names were used; the first name used would have been Oka. Names that were not assigned are marked in <font color="gray">gray</font>.
