The 2019 Pacific hurricane season was an above average season which produced nineteen named storms, most of which were rather weak and short-lived. Only seven hurricanes formed, the fewest since 2010. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. This season was one of the latest-starting Pacific hurricane seasons on record (reliable records began in 1971), with the first tropical cyclone, Hurricane Alvin, forming on June 25.[1] The final system, Tropical Depression Twenty-One-E, dissipated on November 18.
The season had a rather slow start, with no cyclones forming in the basin before the month of June for the first time since 2011. The strongest hurricane of the season, Barbara, formed on June 30 and peaked as a high-end Category 4 hurricane on July 3. August was extremely quiet with no hurricanes forming during the month, a first for a season since 1973. September was much more active with six systems developing, of which three became hurricanes. Activity decreased appreciably in October and November as most of the storms remained weak and short-lived.
Land impact was relatively minor for most of the season. The remnants of Barbara caused power outages in Hawaii in early July. Hurricanes Erick and Flossie both threatened Hawaii, but the systems weakened significantly before reaching the islands, both causing minimal effects. Tropical Storm Ivo caused intense flooding while it remained offshore of Mexico. In late September, Hurricane Lorena made landfall in southwestern Mexico and Baja California Sur, and its remnant moisture entered the southwestern United States. Lorena was responsible for one death and damages worth $50 million (2019 USD). Tropical Storm Narda took a nearly identical track a week later, killing six and causing $15.2 million in damage. Overall, this season was drastically less active and destructive than the previous year, causing about $65.2 million in damages and seven fatalities.__TOC__

On May 15, 2019, the Servicio Meteorológico Nacional (SMN) issued its first forecast for the season, predicting a total of 19 named storms, 11 hurricanes, and six major hurricanes to develop.[3] On May 23, the National Oceanic and Atmospheric Administration released its annual forecast, predicting a 70% chance of a near- to above-average season in both the Eastern and Central Pacific basins, with a total of 15–22 named storms, 8–13 hurricanes, and 4–8 major hurricanes.[4] The reason for their outlook was the forecast of an El Niño to continue through the season, which reduces vertical wind shear across the basin and increases sea surface temperatures, favoring increased tropical cyclone activity. In addition, many global computer models expected a positive Pacific decadal oscillation (PDO), a phase of a multi-decade cycle that favored much warmer than average sea surface temperatures that had been ongoing since 2014 to continue, in contrast to the 1995–2013 period, which generally featured below-normal activity.[5]
The season officially began on May 15 in Eastern Pacific and on June 1 in Central Pacific; both ended on November 30.[6] Initial activity was slow, with the first tropical depression forming on June 25.[7] The strongest storm of the season, hurricane Barbara, reached peak intensity on July 2 as a high-end category 4 hurricane. The season became more active in July, with five tropical cyclones forming, including two storms that intensified into hurricanes. Among them was Hurricane Erick, which reached Category 4 status on July 31.[8] This level of activity came to a halt in August, with only three named storms forming, none of which reached hurricane strength.
On the first day of September, Hurricane Juliette formed, becoming the third major hurricane of the season.[9] Moreover, tropical activity also began in the Central Pacific with the formation of Tropical Storm Akoni on September 3, which dissipated two days later. There were no tropical cyclones for five days until the formation of Hurricane Kiko on September 12 and the formation of Tropical Storm Mario and Hurricane Lorena five days later. In late September, Tropical Storm Narda became the sixth named storm to form during the month, tying the record for the most active September with the seasons of 1966, 1992, 1994, 1997, 2001 and 2005.
Three tropical storms formed in the month of October, the first one was Tropical Storm Ema which formed on October 12 in the Central Pacific, becoming the first such occurrence since 2016 in which more than one tropical cyclone was named in the basin. The second named storm of the month, Octave, formed on October 17 and dissipated two days later without threatening land. Priscilla formed on October 20 and later dissipated the next day while it brushed Western Mexico. In mid-November, Tropical Storm Raymond formed on November 15, just fifteen days before the season officially ended.
The accumulated cyclone energy (ACE) index for the 2019 Pacific hurricane season as calculated by Colorado State University using data from the National Hurricane Center was 97.7 units.[10]

| Formed: | June 25 |
| Dissipated: | June 29 |
| 1-Min Winds: | 65 |
| Pressure: | 992 |
A tropical wave moved off Africa's western coast on June 12, reaching the Caribbean Sea a week later and continuing across Central America. The wave spawned an area of low pressure on June 24, and this feature organized into the season's first tropical depression by 12:00 UTC on June 25 while located a few hundred miles south of Mexico. The depression initially struggled to organize, but it eventually intensified into Tropical Storm Alvin around 12:00 UTC on June 26. As a mid-level ridge steered the storm west, it began to organize in a more favorable environment. After very deep convection fired over its center, Alvin became a minimal Category 1 hurricane by 00:00 UTC on June 28 as it developed a 10miles diameter eye. After attaining peak intensity, the system encountered cooler waters and increasing wind shear, causing it to weaken. Alvin became devoid of deep convection by 06:00 UTC on June 29, degenerating to a remnant low to the west-southwest of Baja California Sur at that time. The remnant low drifted west and dissipated around a day later.[11]

| Formed: | June 30 |
| Dissipated: | July 5 |
| 1-Min Winds: | 135 |
| Pressure: | 930 |
Less than a week after a tropical wave spawned Alvin, a new tropical wave moved off Africa on June 18. It remained disorganized while crossing the Atlantic, and it progressed into the eastern Pacific on June 26. The disturbance organized over the coming days and developed into Tropical Storm Barbara by 06:00 UTC on June 30, having already possessed gale-force winds at the time of formation. It moved quickly westward while struggling to intensify in an environment of wind shear and dry air. By July 1, however, more favorable environmental conditions allowed the storm to intensify. Barbara became a hurricane by 18:00 UTC on July 1 and began to rapidly intensify, ultimately reaching its peak at Category 4 intensity with winds of 155abbr=onNaNabbr=on at 00:00 UTC on July 3. The storm maintained a 15miles diameter eye surrounded by an intense central dense overcast and numerous rainbands at that time. A turn toward the northwest brought the storm into cooler waters and drier air, with an increasingly rapid rate of weakening through July 5. Barbara degenerated to a remnant low by 00:00 UTC on July 6 after losing its deep convection. The low turned west and dissipated into a trough on July 8 to the east-southeast of Hawaii.[12]
Barbara's remnants passed 120miles south of Hawai'i on July 8, producing showers over the windward regions of the island and nearby Maui.[13] The storms generated by Barbara's remnants were cited by Hawaiian Electric Industries as the likely cause of power outages affecting 45,000 electricity customers.[14]

| Formed: | July 6 |
| Dissipated: | July 7 |
| 1-Min Winds: | 45 |
| Pressure: | 1001 |
Another tropical wave moved off Africa on June 23 and crossed into the East Pacific on July 2. The favorable influence of a kelvin wave and the Madden–Julian oscillation allowed the disturbance to organize, and it developed into Tropical Storm Cosme by 12:00 UTC on July 6. Anomalously strong high pressure aided in accelerating the storm's winds, and it attained a peak intensity of 50abbr=onNaNabbr=on upon formation. Thereafter, cooler waters, dry air, and wind shear arrested Cosme's development, and the cyclone began to weaken while turning northwest. By 00:00 UTC on July 8, Cosme degenerated to a remnant low. The low later turned west before dissipating into a trough early on July 11.[15]

| Formed: | July 12 |
| Dissipated: | July 13 |
| 1-Min Winds: | 30 |
| Pressure: | 1006 |
The tropical wave that spawned Cosme was succeeded a week later by another. It entered the East Pacific on July 8 but remained disorganized for several days while tracking west. The wave gave way to an area of low pressure on July 12, which then organized into a tropical depression only six hours later. The depression was located over very warm sea surface temperatures but under the influence of moderate wind shear, preventing organization. By July 12, persistent upper-level winds began to shear away the cyclone's convection. It degenerated to a remnant low at 00:00 UTC on July 14 while located south-southwest of Baja California Sur. The low produced intermittent bursts of convection as it moved west-northwest but ultimately dissipated early on July 15.[16]

| Track: | Dalila 2019 track.png |
| Formed: | July 22 |
| Dissipated: | July 25 |
| 1-Min Winds: | 40 |
| Pressure: | 1004 |
A tropical wave moved off Africa on July 8, showing some signs of organization until it reached the western Caribbean. It continued into the East Pacific and formed a tropical depression around 06:00 UTC on July 22. The cyclone remained disorganized for much of its duration, plagued by northerly wind shear and cooler waters. However, the formation of spiral rain bands allowed it to become Tropical Storm Dalila by 06:00 UTC on July 23; the storm attained peak winds of 45abbr=onNaNabbr=on six hours later. The system progressed over even cooler waters, causing Dalila to become a remnant low by 12:00 UTC on July 25. The low drifted west and dissipated the following day.[17]

| Track: | Erick 2019 track.png |
| Formed: | July 27 |
| Dissipated: | August 4 |
| 1-Min Winds: | 115 |
| Pressure: | 952 |
Erick originated as a tropical wave that emerged off the coastline of Africa on July 12. It entered the eastern Pacific in late July, where convection blossomed in the presence of a very strong kelvin wave. Moderately wind shear slowed the formation process, but a tropical depression finally developed around 12:00 UTC on July 27 and organized into a tropical storm six hours later. Dry air and the elongation of its center likewise slowed organization shortly after development, but a center relocation placed the storm in a favorable environment. Erick intensified into a hurricane at 18:00 UTC on July 29 and began a period of rapid intensification, intensifying by 60abbr=onNaNabbr=on in just 24 hours as it crossed into the central Pacific basin. This bout of strengthening brought Erick to its peak as a Category 4 hurricane with winds of 130abbr=onNaNabbr=on around 18:00 UTC on July 30. The cyclone subsequently weakened while passing south of Hawaii as wind shear increased over the system. Bursts of convection allowed Erick to persist as a tropical cyclone from August 3 to 4. However, the system eventually degenerated to a remnant low by 00:00 UTC on August 5. The remnants of Erick continued moving west and reached the International Date Line on August 8.[18]

| Formed: | July 28 |
| Dissipated: | August 5 |
| 1-Min Winds: | 70 |
| Pressure: | 987 |
A tropical wave moved off Africa on July 16 and crossed into the East Pacific eight days later. The disturbance coalesced while positioned south of Mexico, organizing into a tropical depression by 12:00 UTC on July 28. It slowly intensified while moving rapidly west-northwest, becoming Tropical Storm Flossie early on July 29 and a hurricane later the next day. After attaining peak winds of 80abbr=onNaNabbr=on, the storm weakened amid increasing westerly wind shear. These unfavorable upper-level winds abated on August 1, causing Flossie to fluctuate in intensity for the next day. By August 3, however, the storm embarked on a gradual weakening trend. It degenerated to a remnant low to the north of Hawaii at 00:00 UTC on August 6. The low turned north-northwest and dissipated the next morning.[19]

| Track: | Gil 2019 track.png |
| Formed: | August 3 |
| Dissipated: | August 4 |
| 1-Min Winds: | 35 |
| Pressure: | 1006 |
On July 28, an area of disturbed weather that could not reliably be traced over the Atlantic was noted over Central America. A broad area of low pressure formed on the final day of July and moved west-northwest, gaining enough organization to be declared a tropical depression around 06:00 UTC on August 3. The depression turned northwest after formation and tracked through an unfavorable wind shear environment. Despite this, it intensified into Tropical Storm Gil around 18:00 UTC on August 3, with the center located on the western edge of associated thunderstorm activity. Gil failed to intensify beyond minimal tropical storm intensity, losing its bursting convection as the storm encountered dry air. Gil degenerated to a remnant low around 00:00 UTC on August 5 well to the west-southwest of Baja California Sur. It dissipated the next morning.[20]

| Formed: | August 12 |
| Dissipated: | August 13 |
| 1-Min Winds: | 40 |
| Pressure: | 1003 |
A vigorous tropical wave crossed the coastline of Africa on July 28 and moved west across the Atlantic. The wave nearly organized into a tropical depression over the eastern Caribbean Sea but soon lost organization. After it crossed into the East Pacific on August 9, subsequent interaction with a monsoon trough led to the formation of an area of low pressure, which continued on to become a tropical depression around 00:00 UTC on August 12 to the south of Baja California Sur. Increasing thunderstorm activity led to the designation of Tropical Storm Henriette six hours later. Henriette attained peak winds of 45abbr=onNaNabbr=on before the combination of cooler waters and dry air caused weakening, degenerating into a remnant low around 12:00 UTC on August 13 and dissipating two days later.[21]

| Track: | Ivo 2019 track.png |
See main article: Tropical Storm Ivo (2019). Two tropical waves crossed the Atlantic in quick succession. The leading tropical wave spawned an area of low pressure over the eastern Pacific on August 6, while the second wave enhanced the low's convection. The disturbance gradually developed into a tropical depression by 06:00 UTC on August 21; it intensified into Tropical Storm Ivo six hours later. Favorable atmospheric conditions allowed Ivo to intensify over subsequent days, and it reached a peak intensity of 70abbr=onNaNabbr=on early on August 22 as a mid-level eye became evident on microwave imagery. Although increasing wind shear caused it to slowly weaken, Ivo passed close to Clarion Island early on August 23, producing sustained winds of 61mph and gusts to 76mph. The storm continued to weaken as it entered cooler waters. It degenerated to a remnant low around 06:00 UTC on August 25. The low meandered for a while before dissipating early on August 27 to the west of Baja California Sur.[22]

| Track: | Juliette 2019 track.png |
| Formed: | September 1 |
| Dissipated: | September 7 |
| 1-Min Winds: | 110 |
| Pressure: | 953 |
On August 18, a tropical wave moved off Africa. It inconspicuously crossed the Atlantic and emerged into the East Pacific on August 27. A broad area of low pressure formed in association with increased convective activity, leading to the formation of Tropical Storm Juliette by 00:00 UTC on September 1. The newly formed storm quickly organized amid favorable conditions, becoming a hurricane by 12:00 UTC on September 2 and entering a period of rapid intensification. Within a day, Juliette attained its peak at Category 3 intensity with winds of 125abbr=onNaNabbr=on. Beyond that time, the cyclone's eyewall collapsed and caused a persistent weakening trend. Juliette degenerated to a remnant low 06:00 UTC on September 7 to the west of Baja California Sur. The low drifted west and dissipated early on September 9.[23]

| Track: | Akoni 2019 track.png |
| Formed: | September 4 |
| Dissipated: | September 6 |
| 1-Min Winds: | 35 |
| Pressure: | 1004 |
Early on September 4, the NHC began to track a quickly-developing area of low pressure about 1,100 mi (1,770 km) east-southeast of the Big Island of Hawaii.[24] Just a few hours later, following a sudden increase in convection, the system organized into Tropical Depression Twelve-E and moved into the Central Pacific basin.[25] It slowly intensified and eventually reached tropical storm status, whereupon it was named Akoni.[26] The system struggled to organize because of high wind shear and quickly degenerated into a remnant low on September 6.[27]
| Basin: | EPac |
| Track: | Kiko 2019 track.png |
| Formed: | September 12 |
| Dissipated: | September 24 |
| 1-Min Winds: | 115 |
| Pressure: | 950 |
The final major hurricane of the season originated as a tropical wave that moved off Africa on August 27. It crossed into the East Pacific on September 7, where it spawned a tropical depression by 06:00 UTC on September 12. The depression intensified into Tropical Storm Kiko twelve hours later but struggled to organize further as it underwent multiple center reformations. Beginning at 00:00 UTC on September 14, however, Kiko entered a period of rapid intensification that brought the storm to its peak as a Category 4 hurricane with winds of 130abbr=onNaNabbr=on a little over a day later. It displayed a prominent spiral band wrapping into a symmetric central dense overcast and large eye at that time. After reaching peak intensity, Kiko fluctuated in intensity due to varying atmospheric conditions while tracing a sinusoidal path across the Pacific. The storm finally lost its deep convection on September 24 and degenerated to a remnant low by 18:00 UTC as a result. The low turned west and dissipated on September 27.[28]

| Track: | Lorena 2019 track.png |
| Formed: | September 17 |
| Dissipated: | September 22 |
| 1-Min Winds: | 75 |
| Pressure: | 985 |
See main article: Hurricane Lorena (2019). A large tropical wave departed Africa on September 4 and entered the East Pacific by September 16. The disturbance quickly organized upon emerging over water, and it became Tropical Storm Lorena at 06:00 UTC on September 17 while moving northwest. Lorena became a hurricane on September 19 while passing very close to the coastline of Jalisco and made landfall near Chatmela-Cuixmala with winds of 75abbr=onNaNabbr=on six hours later. Lorena weakened as it emerged back offshore, but it became a hurricane a second time and reached peak winds of 85abbr=onNaNabbr=on late on September 20 as an eye appeared on satellite. The storm struck Baja California Sur near La Ventana at a slightly reduced strength at 03:00 UTC on September 21. Lorena weakened thereafter as it curved north, degenerating to a remnant low as it reached the coastline of mainland Mexico around 12:00 UTC on September 22 and dissipating six hours later.[29]
| Basin: | EPac |
| Track: | Mario 2019 track.png |
| Formed: | September 17 |
| Dissipated: | September 22 |
| 1-Min Winds: | 60 |
| Pressure: | 991 |
A tropical wave, the same that spawned Tropical Storm Gabrielle in the Atlantic, left Africa on August 30 and progressed into the eastern Pacific on September 13. The wave led to the formation of a tropical depression around 12:00 UTC on September 17 and Tropical Storm Mario twelve hours later. Although Mario was located in close proximity to strengthening Tropical Storm Lorena and experienced shear from that storm's outflow, it still intensified to a peak of 70abbr=onNaNabbr=on late on September 18 while weaving its way north across the Pacific. Shortly thereafter, upper-level winds increased further and caused a weakening trend that caused the system to degenerate to a remnant low by 00:00 UTC on September 23. The low moved parallel to Baja California Sur before turning east and dissipating just west of the state late on September 24.[30]

| Track: | Narda 2019 track.png |
| Formed: | September 29 |
| Dissipated: | October 1 |
| 1-Min Winds: | 45 |
| Pressure: | 997 |
See main article: Tropical Storm Narda (2019). The deadliest tropical cyclone of the season originated as a tropical wave that left Africa on September 15. The wave entered the eastern Pacific on September 26, where it became embedded within the Intertropical Convergence Zone and organized. Tropical Storm Narda developed around 00:00 UTC on September 29 as a result. The nascent cyclone moved quickly northwest and made landfall northeast of Lázaro Cárdenas, Michoacán, at 14:00 UTC on September 29 harboring winds of 45abbr=onNaNabbr=on. Mountainous terrain slightly weakened Narda as it crossed over land, but its large circulation and outside orographic effects aided in the maintenance of tropical storm-force winds. The storm immediately re-intensified once over water and attained peak winds of 50abbr=onNaNabbr=on while developing a mid-level eye feature. Narda made a second landfall near Las Glorias around 00:00 UTC on October 1 at peak strength. It rapidly weakened after moving inland and dissipated six hours later over southern Sonora.[31]
Narda brought heavy rains and flooding in southwestern Mexico. Two people were killed in Oaxaca, one in Colima, and one in Guerrero.[32] [33]

| Track: | Ema 2019 track.png |
| 1-Min Winds: | 45 |
| Pressure: | 1003 |
An area of low pressure developed a few hundred miles to the west of Hawaii on October 12. The system was assessed as having a low chance of development by the Central Pacific Hurricane Center; however, the system quickly organized later the same day. Gale-force winds soon developed, and consequently the CPHC upgraded the system to a tropical storm at 15:00 UTC, naming it Ema.[34] Ema's existence was short-lived, however, as the storm weakened due to strong wind shear and degenerated to a remnant low on October 14.[35]
| Basin: | EPac |

| Formed: | October 17 |
| Dissipated: | October 19 |
| 1-Min Winds: | 40 |

An area of low pressure materialized within the monsoon trough across the eastern Pacific on October 15. The low drifted west-southwest and organized into a tropical depression around 12:00 UTC on October 17 before further intensifying into Tropical Storm Octave twelve hours later. The small storm attained peak winds of 45abbr=onNaNabbr=on within a small central dense overcast before it drifted northward into an environment of dry air that prompted weakening. Octave degenerated to a remnant low around 18:00 UTC on October 19 as it curved east-northeast and later south-southwest. The remnant low dissipated two days later in the vicinity of where it first developed.[36]

Another tropical wave moved off Africa on October 3 and fractured over the Caribbean Sea, with the northern portion spawning Tropical Storm Nestor in the Atlantic. The southern portion continued into the eastern Pacific, leading to the formation of a tropical depression around 00:00 UTC on October 20. It intensified into Tropical Storm Priscilla six hours later while turning north. Having spent little time over water, and affected by moderate easterly wind shear, Priscilla quickly moved into the coastline near Cuyutlán, Colima, at 19:30 UTC on October 20 as a minimal tropical storm. The cyclone weakened quickly once inland and dissipated by 06:00 UTC on October 21 over the rugged terrain of southwestern Mexico.[37]
Priscilla and its precursor disturbance over Mexico caused heavy flooding and mudslides in and around areas Manzanillo.[38]

Yet another tropical wave left Africa on October 27. This feature entered the East Pacific on November 6, where it was enhanced by an ongoing Gulf of Tehuantepec gap wind event and an eastward-moving kelvin wave. The wave spawned a tropical depression by 12:00 UTC on November 14. It moved north and north-northwest while remaining largely disorganized in the presence of moderate northwesterly wind shear. By 06:00 UTC on November 15, the depression intensified into Tropical Storm Raymond. It attained peak winds of 50abbr=onNaNabbr=on later that day before encountering increased wind shear from the southwest. Raymond slowly decayed and dissipated after 00:00 UTC on November 18 to the south of Baja California Sur.[39]
The remnants of the storm brought heavy rain to Southern California and Arizona, leaving over 13 million people under flash flood watch and alleviating unusually dry conditions, bringing the first significant rainfall to Southern California since May.[40] The system also brought heavy snow to higher elevation areas.[41]

On November 2, a late-season tropical wave moved off the west coast of Africa. The wave entered the eastern Pacific on November 12 and spawned an area of low pressure the next day. A strong gap wind event kept the system disorganized as it passed south of the Gulf of Tehuantepec. Afterwards, deep convection began to develop closer to the center of the low, and the low's circulation became more apparent. This resulted in the formation of the season's final tropical depression around 00:00 UTC on November 16. Multiple center reformations and intrusions of dry air arrested development despite another favorable environment. This resulted in weakening, and the depression dissipated after 12:00 UTC on November 18.[42]
See main article: Potential Tropical Cyclone Seventeen-E. A tropical wave entered the eastern Pacific by October 14, where it spawned a broad area of low pressure. The disturbance became better defined over the coming days, prompting the NHC to initiate advisories on Potential Tropical Cyclone Seventeen-E at 03:00 UTC on October 16 and facilitate tropical storm watches along the coastline of Mexico. The disturbance soon became poorly organized, as its convection dwindled and its center became less defined. The system moved inland between Bahias de Huatulco and Salina Cruz in the Mexican state of Oaxaca without ever having formed into a tropical cyclone.[43] Gusty winds and heavy rain affected parts of El Salvador, causing significant damage. Four people died in storm-related incidents: three from flooding and one from a fallen tree. Eighty families required evacuation in Cangrejera.[44]
The following list of names was used for named storms that formed in the North Pacific Ocean east of 140°W during 2019.[45] This was the same list used in the 2013 season, with the exception of the name Mario, which replaced Manuel.[46] [47] The name Mario was used for the first time this year. No names were retired following the season, so this list will be used again for the 2025 season.

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.[46] Two named storms, listed below, formed within the area in 2019.[48] Their names were from List1, as the final name on List4 had been used the previous season for Hurricane Walaka. List1 was first used 37 years earlier, during the 1982 season.[49] [50] Named storms in the table above that crossed into the area during the year are noted (*).[48]

This is a table of all of the tropical cyclones that formed in the 2019 Pacific hurricane season. It includes their name, duration (within the basin), peak classification and intensities, areas affected, damage, 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 2019 USD.
