The 2014 Pacific hurricane season is the most active season on record since 1992, and the fourth most active since reliable records began. The season officially started on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they will both end on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year.

The season began with an active start, with three tropical cyclones developing before June 15, including two Category 4 hurricanes, of which one became the strongest tropical cyclone ever recorded in May in the East Pacific. After a less active period in late June and early July, activity once again picked up in August, and persisted throughout September and October. The active season resulted in numerous records, including Hurricane Amanda, the strongest May hurricane and earliest Category 4 on record, Hurricane Cristina, the earliest second major hurricane, Hurricane Genevieve, the first tropical cyclone to exist in all three Pacific basins since Hurricane Jimena in 2003, Hurricane Iselle, the strongest tropical cyclone on record to strike the Big Island of Hawaii, Hurricane Marie, the first Category 5 Pacific hurricane since Hurricane Celia in 2010, Hurricane Odile, the most destructive tropical cyclone of the season and the most intense tropical cyclone to make landfall over the Baja California peninsula and Hurricane Simon, the record breaking ninth major hurricane and sixth Category 4 hurricane of the season.

Seasonal forecasts
On March 12, 2014, the Servicio Meteorológico Nacional (SMN) issued their first outlook for the Pacific hurricane season, expecting a total of fifteen named storms, seven hurricanes, and three major hurricanes. A month later, the agency revised their outlook to fourteen named storms, seven hurricanes, and five major hurricanes, citing the anticipated development of El Niño for above-average activity, compared to the 1949-2013 average of 13.2, On May 22, the Climate Prediction Center (CPC) announced its prediction of 14 to 20 named storms, seven to eleven hurricanes, three to six major hurricanes, and an Accumulated Cyclone Energy (ACE) within 95-160% of the median. It also called for a 50 percent chance of an above-normal season, a 40 percent chance of a near-normal season, and a 10 percent chance of a below-normal season. Similar to the SMN outlook, the basis for the forecast was the expectation of below average wind shear and above average sea surface temperatures, both factors associated with El Niño conditions. Within the Central Pacific Hurricane Center (CPHC) 's jurisdiction, four to seven tropical cyclones were expected to form, near or above the average of four to five tropical cyclones.

Seasonal summary
The season's first named storm, Amanda, developed on May 23, shortly after the official start to the Pacific hurricane season on May 15. Based on the 1971–2009 long-term average, the average date for the first named storm is June 10. On May 24, the system intensified into a hurricane, transcending the climatological average date of June 26 for the first hurricane. The next day, Amanda attained major hurricane status, over a month sooner than the average date of July 19.

The Accumulated Cyclone Energy (ACE) index for the season is 150.3575 units for the East Pacific and 40.65 units for the Central Pacific. Through June 14, the seasonal ACE reached its highest level since 1971, when reliable records began, for so early in the season. By the end of June, the ACE total remained at 230% of the normal value, before subsiding to near-average levels to end July. Activity in August ramped up significantly, with four hurricanes developing during the month, two of which became major hurricanes; Iselle, which formed on July 31, also became a major hurricane. By the end of August, ACE values rose to 60% above the 30-year average. Continued, though less prolific, activity extended through September with four hurricanes developing that month. ACE values remained 45% above-average by the end of the month.

Following the rapid intensification of Hurricane Simon to a Category 3 hurricane during the afternoon of October 4, the 2014 season featured the highest number of major hurricanes in the Eastern Pacific basin since the advent of satellite imagery. With eight such storms east of 140°W, the year ties with the record set in the 1992 season.

Hurricane Amanda
On May 19, the National Hurricane Center (NHC) began monitoring an area of disturbed weather south-southwest of the Gulf of Tehuantepec for potential tropical cyclogenesis. Steered west-northwest around a mid-level ridge over Mexico, the system steadily organized as deep convection increased and the low-pressure center became better defined; in accordance with a scatterometer pass, advisories were initiated on the first tropical depression of the season at 21:00 UTC on May 22. The depression was upgraded to Tropical Storm Amanda eighteen hours later. Amid a favorable atmospheric environment, the cyclone began a period of rapid deepening, marked by an increase in winds from 75 mph (120 km/h) at 15:00 UTC on May 24 to winds of 155 mph (255 km/h) at 15:00 UTC the next day. Shortly thereafter, an increase in wind shear and decrease in moisture and sea surface temperatures, led Amanda to a steady weakening trend. The cyclone weakened below major hurricane intensity at 03:00 UTC on May 27, below hurricane intensity at 03:00 UTC on May 28, and below tropical storm intensity at 15:00 UTC on May 29. Six hours later, Amanda degenerated into a non-convective remnant low.

Under the anticipation of heavy rains and landslides, weather alerts were issued for Guerrero and Manzanillo. Thirty-four shelters opened in Michoacán while 80 opened in Guerrero. Heavy rains occurred Guerrero, resulting in flooding. A river near Coyuca de Benítez overflowed its banks. Three trees were brought down and a vehicle in Acapulco was destroyed. State-wide, one person was killed when a tree that had fallen on the road resulted in a fatal car wreck. In Colima, minor landslides occurred, resulting in the closure of Federal Highway 200. Much of Michoacán was battered by large waves and heavy rains, resulting in two casualties. Several roads were destroyed in Zitácuaro. On May 25, Amanda became the second-earliest East Pacific major hurricane on record, behind 2012's Hurricane Bud. Later that day, it also became the strongest May tropical cyclone in the Eastern Pacific basin in the satellite era, eclipsing the previous record set by Hurricane Adolph in 2001, which had peak winds of 145 mph (230 km/h).

Tropical Storm Boris
The formation of Boris is attributed to a low-level trough that entered the East Pacific from the southwestern Caribbean Sea on May 28. A broad area of low pressure developed in association with the trough south of the Mexico–Guatemala border two days later, and the disturbance steadily organized with aid from an eastward-moving convectively-coupled kelvin wave. By 18:00 UTC on June 2, the system acquired enough organization to be deemed a tropical depression. Tracking northward, the depression steadily became better defined as spiral bands developed over the eastern semicircle of the circulation. After intensifying into a tropical storm at 12:00 UTC on June 3 and attaining peak winds of 45 mph (75 km/h) six hours later, increasing land interaction caused Boris to begin weakening. It was downgraded to a tropical storm early on June 4 and subsequently degenerated into a remnant low at 18:00 UTC. The remnant low turned northwestward and dissipated shortly thereafter.

Posing a considerable rainfall and mudslide threat to Guatemala, classes were suspended in nine school districts, impacting 1.25 million pupils. Similarly, some classes were suspended in the Mexican states of Chiapas and Oaxaca. In the former, roughly 16,000 people were evacuated out of hazardous areas. Most of the impacts associated with Boris were due to its developing precursor, whose heavy rainfalls caused 20 mudslides, killing five and resulting in extensive property damage. Heavy rainfall in Chiapas caused rivers to overflow their banks, resulting in minor damage. Overall, the effects of Tropical Storm Boris and its precursor killed six people across Central America.

Hurricane Cristina
A tropical wave emerged off the western coast of Africa on May 26 and traveled quickly westward, entering the East Pacific on June 5. Two days later, the wave merged with a preexisting area of low pressure and began to organize, aided by a convectively-coupled kelvin wave. As convective bands formed near and east of the center, the disturbance acquired enough organization to be declared a tropical depression by 12:00 UTC on June 9. Steered west-northwest around a ridge over Mexico, the depression only slowly organized due to moderate shear and was upgraded to Tropical Storm Cristina early the next day. Following a reprieve in upper-level winds, the cyclone intensified into a Category 1 hurricane at 06:00 UTC on June 11 and began a period of rapid deepening thereafter. After attaining peak winds of 150 mph (240 km/h) early on June 12, an increasingly unfavorable environment caused the system to commence a weakening trend. At 12:00 UTC on June 14, Cristina was downgraded to a tropical storm; at 06:00 UTC the subsequent day, it was declared a remnant low after remaining devoid of deep convection. The remnant low continued west-northwestward until dissipating early on June 19.

Under the anticipation of 12 ft waves, a "yellow" alert was issued for Colima, Guerrero, Oaxaca, and parts of Jalisco and Michoacan. Along Manzanillo, strong waves resulted in minor flooding that damaged one road.

Tropical Storm Douglas
The NHC began monitoring a large area of disturbed weather offshore the coast of southern Mexico on June 25. A broad area of low pressure formed in association with the disturbance two days later, and it steadily organized amid favorable environmental conditions. Steered west-northwest around a ridge over Mexico, the disturbance acquired sufficient organization to be declared a tropical depression at 21:00 UTC on June 28. As convection continued to consolidate over the center and a primitive spiral band organized, the depression was upgraded to Tropical Storm Douglas. After attaining peak winds of at least 45 mph (75 km/h), a track over cooler waters and into a more stable environment caused the storm to weaken to a tropical depression by 09:00 UTC on July 5. Six hours later, the depression degenerated into a remnant low.

Tropical Storm Elida
A well-defined tropical wave moved emerged off the western coast Africa on June 20. After entering the East Pacific a week later, shower and thunderstorm activity began to increase. Although the system lacked a closed low initially, a small circulation was noted by 06:00 UTC on June 30, and the system was declared Tropical Storm Elida accordingly. Paralleling the southwestern coast of Mexico, the cyclone attained peak winds of 45 mph (75 km/h) before strong northwesterly wind shear from nearby Tropical Storm Douglas caused the storm to become disheveled. It weakened to a tropical depression at 00:00 UTC on July 2 and degenerated into a remnant low six hours later. The remnant low drifted southeastward before dissipating early on July 3.

Tropical Storm Fausto
A tropical wave moved off the western coast of Africa on June 22 and entered the East Pacific eight days later. On July 4, convection increased with the aid of a convectively-coupled kelvin wave, and two days later, a broad area of low pressure formed along the wave axis well south-southwest of Baja California. After further organization, the disturbance was declared a tropical depression at 12:00 UTC on July 7. Steered westward around a subtropical ridge, the depression intensified into Tropical Storm Fausto six hours later and simultaneously attained peak winds of 45 mph (75 km/h). By early on July 9, Fausto weakened to a tropical depression as dry air became entrained into the circulation. The low-level center opened up into a trough by 12:00 UTC, marking the demise of the cyclone.

Tropical Storm Wali
The NHC began monitoring a large area of disturbed weather in association with a tropical wave well southwest of the southern tip of the Baja California peninsula on July 13. After crossing into the central Pacific, the disturbance gradually organized, and it acquired enough organization to be declared a tropical depression at 21:00 UTC on July 17. An hour later, data from an ASCAT pass revealed winds up to 45 mph (75 km/h), and the depression was upgraded to Tropical Storm Wali. Steered west-northwestward around a mid-level ridge to the cyclone's northeast, increasing wind shear caused the cloud pattern associated with Wali to become disorganized; at 21:00 UTC on July 18, the system was downgraded to a tropical depression, and by 03:00 UTC the following afternoon, Wali was declared a remnant low after having been devoid of deep convection.

Hurricane Genevieve
A small area of disturbed weather formed well south of Manzanillo, Mexico on July 20. Tracking west-northwestward, deep convection developed about an area of low pressure, leading to the designation of Tropical Storm Genevieve at 09:00 UTC on July 25. Persistent westerly wind shear caused the low-level center to become exposed to view by early the next day, and in junction with satellite intensity estimates, Genevieve weakened to a tropical depression at 15:00 UTC. The center remained exposed as the storm entered the central Pacific, and the Central Pacific Hurricane Center declared the cyclone a remnant low at 03:00 UTC on July 28. In spite of this, deep convection developed near the circulation once again during the afternoon hours of July 29, and Genevieve was upgraded to a tropical depression. Although intensity guidance suggested the cyclone would slowly intensify into a tropical storm, deep convection faltered by 21:00 UTC on July 31, once again leading to the designation of a remnant low.

Travelling west-southwestward around the south side of a subtropical ridge, deep convection became invigorated once again early on August 2, leading to the classification of Tropical Depression Genevieve for a second time at 15:00 UTC; amid a much improved upper-level pattern, gradual intensification was forecast. The CPHC upgraded Genevieve to a tropical storm at 21:00 UTC on August 5 as curved bands developed north and west of the center. Thereafter, the cyclone began an extraordinary period of intensification, with maximum sustained winds increasing from 75 mph (120 km/h) to 135 mph (215 km/h) in a 12-hour period. Genevieve further intensified into a Category 5-equivalent typhoon as it crossed the International Dateline into the West Pacific.

Hurricane Hernan
On July 24, an area of showers and thunderstorms formed off the coast of southeastern Mexico, and upper-level winds were expected to become more conducive for its development over subsequent days. Given an increase in convection and the formation of banding features, advisories were initiated on a tropical depression at 09:00 UTC on July 26; twelve hours later, it intensified into Tropical Storm Hernan. Steered west-northwest by a ridge over the southwestern United States, the cyclone steadily organized and acquired enough organization to be declared a Category 1 hurricane by 2100 UTC on July 27. Immediately after attaining peak winds of 75 mph (120 km/h), a track over cooler sea surface temperatures and an increase in wind shear caused Hernan to weaken; at 0900 UTC on July 28, it deteriorated into a tropical storm. After having been devoid of deep convection for more than 12 hours, Hernan was declared a remnant low at 15:00 UTC on July 29.

Hurricane Iselle
Hurricane Iselle formed on July 31 about 1075 mi (1730 km) southwest of the southern tip of Baja California. By 0900 UTC August 1, Iselle had developed deep convection in a central dense overcast, and the storm continued to intensify with only light-to-moderate wind shear and warm waters conducive for further development. Iselle continued to travel on a west-northwestward track as it moved around the subtropical ridge to its north, and by 0300 UTC August 2, Iselle had intensified into a Category 1 hurricane with a well-defined eye and cold cloud tops in a small, dense central overcast. Moderate vertical wind shear started to affect Iselle, with the storm's mid-level center being displaced to the south of the low-level center, but despite the shear, Iselle managed to further strengthen to Category 2 intensity by 2100 UTC August 2. At 0300 UTC August 3, it was observed that there Iselle was still continuing to strengthen, with the central dense overcast continuing to become symmetric and the eye becoming better defined. By 1500 UTC August 3, Iselle had intensified to a Category 3 hurricane. Iselle began to take on a more circular shape, and Iselle's convective cloud tops began to expand as the storm's structure began to exhibit many characteristics of an annular hurricane. Iselle continued to intensify as it tracked west, and by 1500 UTC August 4, Iselle had attained Category 4 intensity, with a 25-30 nm eye with convective cloud tops as cold as -75 °C surrounding it.

Hurricane Julio
On July 31, the NHC began monitoring disorganized convection in association with a tropical wave south of Acapulco, Mexico. Thunderstorm activity increased and organized over subsequent days, leading to the formation of a tropical depression at 03:00 UTC on August 4, and the designation of Tropical Storm Julio six hours later. In conjunction with moderate northeasterly shear, little change in strength was observed initially; by early on August 6, however, atmospheric conditions became more favorable, and the cyclone was upgraded to a Category 1 hurricane. With an improving satellite presentation, including a warm eye, Julio was upgraded to a Category 2 hurricane at 09:00 UTC on August 7, and further to a Category 3 hurricane at 03:00 UTC the next day as the storm began to move into the Central Pacific.

Hurricane Karina
Tropical Depression Eleven-E formed on August 13. Six hours later it had intensified to a tropical storm and was named Karina while located 180 km south of Socorro Island. Tropical Storm Karina had moved due west, and later intensified to a hurricane on August 15 with winds of 75 mph (120 km/h). It then weakened to a tropical storm as it encountered unfavorable conditions, then later rapidly weakened to a low-end tropical storm on the next day. Thereafter, it steadily intensified to near hurricane strength, then had fluctuations in intensity while stalling before executing a loop and eventually re-intensifying to a hurricane on August 22 reaching a new peak intensity of 80 mph (130 km/h) on the next day. It then accelerated while turning northwest where interaction with Post-tropical cyclone Lowell and Hurricane Marie led to the increase of wind shear exposing the cyclone's low-level circulation center, causing it to weaken to a tropical depression on August 25. Karina continued to drift eastward for the next two days, before degenerating into a remnant low early on August 27. Karina's remnant low continued to drift eastward for another several hours, before being absorbed into Hurricane Marie's circulation later on the same day. According to the National Hurricane Center, Karina was the seventh longest lasting storm in the Pacific Ocean east of 140º W.

Hurricane Lowell
The NHC began monitoring a trough of low pressure well west-southwest of Manzanillo, Mexico on August 15. Within a favorable environment for development, the disturbance was upgraded to Tropical Depression Twelve-E at 03:00 UTC on August 18, and further to Tropical Storm Lowell at 03:00 UTC the following day. Steered northwestward in response to an upper-level trough over California, the cyclone steadily organized, with its satellite appearance consisting of a large ragged eye; at 15:00 UTC on August 21, Lowell intensified into a Category 1 hurricane and reached peak winds of 75 mph (120 km/h). Thereafter, a track over cooler sea surface temperatures led to a steady weakening trend. At 03:00 UTC on August 22, the system was downgraded to a tropical storm, and by early on August 24, Lowell no longer maintained the coverage and duration of convection to be considered a tropical cyclone. During the next several days, Lowell's remnants continued to accelerate west-northwestward, while slowly diminishing. On August 28, Lowell's remnant circulation collapsed, while situated at the eastern boundary of the Central Pacific basin.

Hurricane Marie
A broad area of low pressure formed several hundred miles south-southeast of the Gulf of Tehuantepec on August 19. Tracking west-northwestward south of a mid-level ridge over the southern United States and northern Mexico, curved bands of deep convection organized about a well-defined center, leading to the formation of a tropical depression at 03:00 UTC on August 22; six hours later, the depression was upgraded to Tropical Storm Marie. With the storm situated over warm sea surface temperatures and in a low wind shear environment, Marie rapidly intensified almost immediately after being upgraded, becoming a Category 1 hurricane at 09:00 UTC on August 23, a Category 2 hurricane at 03:00 UTC on August 24, and a Category 4 hurricane at 09:00 UTC on August 25. With satellite intensity estimates rising to T7.0/140kt, Marie was upgraded to a Category 5 hurricane at 21:00 UTC that day, the first since Hurricane Celia in 2010. Succeeding peak intensity, a combination of drier air, cooler ocean temperatures, and the start of an eyewall replacement cycle all caused Marie to begin weakening: at 09:00 UTC on August 26, the storm fell below major hurricane intensity, and at 21:00 UTC on August 27, the storm weakened below hurricane intensity. After lacking deep convection over the center for several hours, Marie was downgraded to a remnant low early on August 29.

Hurricane Norbert
The NHC began monitoring a large area of disturbed weather in association with a trough of low pressure near the south-central coast of Mexico on August 31. Amid a favorable atmospheric environment, the disturbance steadily organized and was acquired sufficient organization to be declared Tropical Storm Norbert at 15:00 UTC on September 2. The cyclone moved generally northwestward following formation, steered on the southwestern side of a mid-level ridge over northern Mexico. With a symmetric central dense overcast and curved bands wrapping into the center, Norbert was upgraded to a Category 1 hurricane at 03:00 UTC on September 4. Initially steady state, the cyclone began a period of rapid deepening early on September 5, becoming a Category 2 hurricane at 00:00 UTC and a Category 3 hurricane at 06:00 UTC. After attaining peak winds of 120 mph (195 km/h), the effects of cooler ocean temperatures began to weaken the system. Norbert weakened below major hurricane intensity at 21:00 UTC on September 6 and below hurricane intensity at 15:00 UTC on September 7. After lacking deep, organized convection for over 12 hours, Norbert was declared post-tropical at 09:00 UTC on September 8.

Hurricane Odile
On September 7, the NHC began monitoring disorganized convection in association with a trough several hundred miles south of the Mexico coastline. The disturbance gradually organized within an environment of moderate northeasterly wind shear, and it acquired sufficient organization to be declared a tropical depression at 0900 UTC on September 10. Six hours later, it was upgraded to Tropical Storm Odile. Over the coming days, only slow intensification occurred as upper-level winds remained unfavorable; by early on September 13, however, the satellite presentation began to change quickly, with the center fully embedded within a central dense overcast. In conjunction with satellite intensity estimates, the cyclone was upgraded to a Category 1 hurricane at 09:00 UTC. Odile then began a period of rapid deepening, becoming a Category 2 hurricane at 00:00 UTC, a Category 3 hurricane at 06:00 UTC, and a Category 4 hurricane at 09:00 UTC on September 14. After reaching peak winds of 135 mph (215 km/h), the start of an eyewall replacement cycle caused the system to weaken to a Category 3 hurricane. Eight hours later, Odile made landfall near Cabo San Lucas with winds of 125 mph (205 km/h). Over the next two days, Odile slowly weakened as it traversed the mountainous terrain of the Baja peninsula, and eventually re-emerged into the northern Gulf of California as a 50 mph (85 km/h) tropical storm on September 16. The next day, after crossing the gulf, Odile made its' final landfall in northwestern Mexico as a tropical depression, and lost tropical characteristics shortly thereafter. These remnants would persist for a further two days before finally dissipating near the Arizona/New Mexico border on September 19.

Tropical Depression Sixteen-E
On September 9, the NHC began monitoring an area of low pressure that had formed well to the south-southwest of Baja California, though any immediate development of the system was not anticipated. Over the next two days, the disturbance slowly began to organize, and on September 11, the NHC initiated advisories on Tropical Depression Sixteen-E. Initially forecast to attain minimal tropical storm strength, unfavorable outflow generated by the much larger Odile hindered any significant intensification. Despite this hostile environment, the small depression continued to persist over the next few days while moving in a generally eastward direction. But by September 15, Sixteen-E's circulation had become elongated and detached from what little deep convection remained. As a result, the NHC discontinued advisories on the system at 0300 UTC.

Hurricane Polo
One tourist was killed while going missing and three, including two fisherman, were missing in Guerrero. A total of 190 restaurants and 20 shops were damaged. Damage totaled around $100 million MXN ($7.5 million USD).

Hurricane Rachel
On September 20, a low pressure area from Central America entered the Eastern Pacific Ocean. With environmental conditions favorable for further intensification, the NHC gave the system a high probability of development as it continued to move west-northwestward. On September 24, while situated about 285 mi (460 km) south-southwest of Manzanillo, Mexico, the system acquired enough organization for the NHC to declare it Tropical Depression Eighteen-E. Roughly twelve hours later, the depression was upgraded to a tropical storm and given the name Rachel. By September 27, an eye-like feature had begun to appear in infrared satellite imagery. With the aforementioned eye becoming more apparent in visible imagery, surrounded by a convective ring of cooling cloud tops, Rachel was upgraded to a Category 1 hurricane, the thirteenth of the season, later that same day. Two days later, as the result of increasing shear and a decrease in overall convection, Rachel was downgraded to a tropical storm. By September 30, all deep convection had disappeared, and the system was further downgraded to a tropical depression. Later on the same day, the NHC issued its final advisory on the system, as Rachel had degenerated into a remnant low.

Hurricane Simon
On September 27, the NHC began monitoring a broad area of low pressure that had formed off the coast of southeastern Mexico, and assessed its' immediate development potential as low. Over the next several days, the system slowly began to organize, and by October 1, it had acquired enough deep convection to be considered a tropical cyclone, at which time the NHC initiated advisories on Tropical Depression Nineteen-E. By the next day, with banding features becoming better organized and the estimated center located directly below the deep convection, the depression was upgraded to Tropical Storm Simon, the eighteenth of the Eastern Pacific season and nineteenth overall. Late on October 3, Simon's winds reached 75 mph (120 km/h), making it the fourteenth hurricane of the season. The following day, Simon entered a period of rapid intensification and became the ninth major hurricane of the year, in the East Pacific basin.

Hurricane Ana
An area of deep convection and a low pressure area merged and became Tropical Depression Two-C on October 13. It slowly intensified and turned northwestward, developing into Tropical Storm Ana. The storm continued intensifying and was upgraded to a strong tropical storm. Ana turned westward, strengthening into a Category 1 hurricane on October 17. As Ana kept south of the island chain, the hurricane produced large waves and winds. Consequently, the Central Pacific Hurricane Center initiated hurricane watches. Ana was downgraded to a tropical storm very early on October 20.

Beginning on October 15, various tropical cyclone warnings and watches were issued for the state, starting with a tropical storm watch for the Big Island. Three days later, a tropical storm warning was issued for Kauai and Nihau, and was extended to include portions of the Papahānaumokuākea Marine National Monument. The threat of the storm forced parks and beaches to close in the state. While passing south of Hawaii, Ana produced heavy rainfall on most of the islands, peaking at 11.67 in at Keaumo on the Big Island. The rains caused the Sand Island water treatment plant in Honolulu to overflow, which sent about 5,000 gallons of partially treated wastewater into Honolulu Harbor. On October 25, Ana was downgraded to a tropical storm for the second time. Ana continued on a track to the northwest and weakened even further. The system eventually turned north and once again re-strengthened into a high-end tropical storm. Ana turned northwest and soon northeast, fluctuating in strength before being picked up by the Jet Stream. While racing off to the northeast at nearly 40 mph, Ana once again strengthened into a Category 1. After yet again being downgraded to a tropical storm, Ana became extratropical far to the northeast of Hawaii on October 26.

Tropical Storm Trudy
Tropical Storm Trudy formed from a large area of low pressure off Mexico's Pacific coast late on October 17. An NHC statement forecasting life-threatening flash floods and mudslides in southern regions of the country was quickly released.

Even after weakening to a depression, Trudy still posed a threat to Mexico with flooding rain and mudslides. Heavy rain was the primary concern for the Mexican states of Guerrero and Oaxaca. These areas were at risk for flooding downpours through Sunday, despite the storm moving onshore and weakening.

Trudy's remnant low dissipated on October 19, the remnant energy of which crossed Mexico and developed into Tropical Depression Nine on October 22, which degenerated into a remnant low and reintensified into Tropical Storm Hanna on October 27.

Hurricane Vance
A cluster of thunderstorms consolidated with convection formed well southeast of Mexico on October 26. The area was first noted as a tropical disturbance by the NHC the next day. As it moved in a general westward direction, it was upgraded to Tropical Depression Twenty-One-E on October 30. On October 31, the depression was upgraded to Tropical Storm Vance. Although the system maintained its strength early on November 1, it then weakened due to some weakening cloud cover and convection. As predicted, Vance rapidly intensified and attained Category 2 strength on November 3. However, strong shear caused Vance to curve northward and weaken into a Category 1. On November 4, Vance started a slow weakening trend, becoming a weak Category 1 by the following day. Vance continued its weakening trend and veered northeastward. The NHC finally discontinued issuing advisories late on November 5, as Vance weakened into a remnant low.

Storm names
The following names will be used for named storms that form in the northeastern Pacific Ocean during 2014. Retired names, if any, will be announced by the World Meteorological Organization in the spring of 2015. The names not retired from this list will be used again in the 2020 season. This is the same list used in the 2008 season with the exception of Amanda, which replaced Alma; the name Amanda was used for the first time in 2014.

For storms that form in the Central Pacific Hurricane Center's area of responsibility, encompassing the area between 140 degrees west and the International Date Line, all names are used in a series of four rotating lists. The next four names slated for use are shown below.

Season effects
This is a table of all of the storms that have formed in the 2014 Pacific hurricane season. It includes their duration, names, landfall(s), denoted in parenthesis, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2014 USD.
