The 2019 Pacific hurricane season is an ongoing event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the eastern Pacific Ocean. The season officially began 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 had a slow start, with no tropical cyclones forming in the basin during the month of May for the first time since 2016 (though Hurricane Pali formed in January 2016), and the first time that no storms formed before the month of June since 2011. The season became the latest-starting Pacific hurricane season on record since reliable records began in 1971, with the first tropical depression forming on June 25.[1] For the first time since 1973, no hurricanes formed in the basin in the month of August.

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 6 major hurricanes to develop.[4] 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.[5] 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.[6]

Seasonal summaryEdit

Saffir–Simpson scale 

The season officially began on May 15 in Eastern Pacific and on June 1 in Central Pacific; both will end on November 30.[7] Initial activity was slow, with the first tropical depression forming on June 25. The strongest storm of the season so far, 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]

The Accumulated Cyclone Energy (ACE) index for the 2019 Pacific hurricane season, as of 09:00 UTC September 17, is 62.2975 units in the Eastern Pacific and 13.3025 units in the Central Pacific. The total ACE in the basin is 75.6 units.[nb 1]

SystemsEdit

Hurricane AlvinEdit

Category 1 hurricane (SSHWS)
DurationJune 25 – June 29
Peak intensity75 mph (120 km/h) (1-min)  992 mbar (hPa)

On June 19, the National Hurricane Center (NHC) began to forecast the formation of a low-pressure area off the southwestern coast of Mexico within the next several days.[10] An area of disorganized showers and thunderstorms, associated with a westward-moving tropical wave, developed in the region on June 22, with a low-pressure system forming in association with the system on the following day.[11] During the next few days, the system gradually organized as it moved west-northwestward, away from the coast of Mexico. By 12:00 UTC on June 25, the disturbance had developed sufficiently organized convection as well as a sufficiently-defined center of circulation to be classified as a tropical depression, the first of the 2019 Pacific hurricane season.[12] The tropical depression slowly strengthened while moving westward, becoming a tropical storm and receiving the name Alvin approximately a day later.[13] Warm sea surface temperatures, low vertical wind shear, and high relative humidity provided a generally favorable environment for Alvin to strengthen over the next couple of days, as it was steered westward to the south of a subtropical ridge.[14] Early on June 28, by 00:00 UTC, Alvin reached its peak intensity and strengthened into a Category 1 hurricane, becoming the first hurricane of the season. Microwave imagery revealed that Alvin possessed a small inner core, with an eye around 11.5 miles (18.5 km) in diameter.[15] However, just six hours later, southwesterly wind shear began to increase as Alvin turned northwestwards, causing the cyclone to weaken back to a tropical storm.[16] Rapid weakening commenced thereafter, as strong southeasterly wind shear and cooler ocean waters began to take their toll, and the cyclone weakened to a tropical depression early on June 29.[17] At 15:00 UTC that day, Alvin degenerated into a post-tropical remnant low, after losing its remaining convection.[18]

Hurricane BarbaraEdit

Category 4 hurricane (SSHWS)
DurationJune 30 – July 5
Peak intensity155 mph (250 km/h) (1-min)  930 mbar (hPa)

On June 26, the NHC began to forecast the formation of an area of low pressure several hundred miles southwest of the southern coast of Mexico, within the next several days.[19] The next day, a tropical wave—accompanied by a broad area of disorganized showers and thunderstorms—moved into the region. The disturbance gradually became better organized over the next few days as it moved westward to west-northwestward.[20] On the afternoon of June 30, after satellite imagery indicated that the disturbance had become better organized and had gale-force winds east of a well-defined center of circulation, the NHC upgraded the system to a tropical storm and named it Barbara.[21]

Barbara continued to move towards the west-northwest, with convection around the center of the storm increasing as conditions remained favorable for further strengthening. At 21:00 UTC on July 1, Barbara intensified into a category 1 hurricane while located roughly 970 miles (1,560 km) southwest of the southern tip of Baja California.[22] The storm then began a period of rapid intensification, developing a robust inner core intensifying into a Category 4 major hurricane by 12:30 UTC on July 2.[23][24] Early the next morning, Barbara reached its peak intensity as a high-end Category 4 hurricane, with a minimum central pressure of 930 millibars (27 inHg) and maximum 1-minute sustained winds of 155 mph (250 km/h).[25]

Soon after reaching peak intensity, the storm began an eyewall replacement cycle,[26] and encountered cooler waters, causing the storm to weaken.[27] This weakening trend accelerated as southwesterly wind shear increased, with the storm weakening to a Category 2 hurricane by 21:00 UTC on July 4.[28] Early the next morning, Barbara weakened into a tropical storm;[29] the storm gradually lost its remaining convection and degenerated into a remnant low at 00:00 UTC on July 6.[30] Barbara's remnants passed 120 mi (190 km) south of Hawai'i on July 8, producing showers over the windward regions of the island and nearby Maui.[31] 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.[32]

Tropical Storm CosmeEdit

Tropical storm (SSHWS)
DurationJuly 6 – July 7
Peak intensity50 mph (85 km/h) (1-min)  1001 mbar (hPa)

On June 28, the NHC began forecasting the development of a tropical disturbance to the south of Mexico within the next several days.[33] Early on July 3, a tropical disturbance associated with a tropical wave formed several hundred miles south of the southern coast of Mexico.[34] Moving into favorable conditions, the disturbance continued to organize slowly, as it was in the vicinity of Hurricane Barbara. On July 6, the disturbance organized into a tropical storm and was named Cosme, becoming the third named system of the East Pacific hurricane season.[35][36] However, a day after the storm was named, Cosme started weakening due to dry air intrusion.[37] At 03:00 UTC on July 8, Cosme weakened into a tropical depression, before degenerating into a convectionless remnant low later that day, after succumbing to a combination of low sea surface temperatures, dry air, and westerly wind shear.[38][39]

Tropical Depression Four-EEdit

Tropical depression (SSHWS)
DurationJuly 12 – July 13
Peak intensity35 mph (55 km/h) (1-min)  1006 mbar (hPa)

At 00:00 UTC on July 6, the NHC began to forecast the potential formation of an area of low pressure, which had the potential to develop into a tropical cyclone within several days.[40] Two days later, thunderstorms formed in association with a tropical wave within the area.[41] Afterward, the system quickly organized and was classified as Tropical Depression Four-E at 21:00 UTC on July 12.[42][43] The system then proceeded to slowly move west-northwestward. However, the storm failed to intensify further, due to dry air and wind shear in the region. Late on July 13, wind shear took its toll on the storm, and Four-E lost almost all of its deep convection, though a few cells continued to persist near the center of the storm.[44] At 15:00 UTC on July 14, the system degenerated into a remnant low.[45]

Tropical Storm DalilaEdit

Tropical storm (SSHWS)
DurationJuly 22 – July 25
Peak intensity45 mph (75 km/h) (1-min)  1004 mbar (hPa)

On July 14, the NHC began to forecast the potential formation of an area of low pressure off the coast of Costa Rica.[46] Twelve hours later, thunderstorms associated with a tropical wave developed, as expected.[47] The system gradually organized and intensified as it moved slowly toward the west-northwest. On July 20, the NHC began to forecast a high chance of tropical cyclone development for the system.[48] On July 22, the disturbance developed a well-defined center of circulation about 600 nautical miles (690 mi; 1100 km) southwest of Baja California, allowing it to be classified as a tropical depression.[49] On the next day, satellite estimates indicated that the system began to produce tropical storm-force winds. As a result, the system was upgraded to Tropical Storm Dalila at 09:00 UTC on July 23, as it moved north-northwestward.[50] Eventually, Dalila emerged into an area of low sea surface temperatures a day later, causing it to weaken to tropical depression status.[51] Dalila encountered even more unfavorable conditions as it continued moving northwestward, causing the storm to degenerate into a remnant low at 15:00 UTC on July 25.[52]

Hurricane ErickEdit

Category 4 hurricane (SSHWS)
DurationJuly 27 – August 5
Peak intensity130 mph (215 km/h) (1-min)  952 mbar (hPa)

The NHC began to forecast the potential formation of a tropical disturbance on July 22.[53] Just twelve hours later, thunderstorms formed within the area.[54] The system gradually organized in the next several days. On July 27, it began to produce tropical storm-force winds, but still lacked a well-defined center of circulation. Later that day, the system's circulation began to organize, leading to the classification of the system as a tropical depression.[55][56] Several hours later, the system intensified into Tropical Storm Erick.[57] The system slowly organized, and at 03:00 UTC on July 30, Erick intensified into a hurricane as it moved westward into the Central Pacific Hurricane Center’s area of responsibility.[58][59] Twelve hours later, Erick rapidly intensified into a Category 3 hurricane.[60] Rapid intensification continued, and at 21:00 UTC on July 30, Erick reached its peak intensity as a Category 4 hurricane, with sustained winds at 115 knots (130 mph; 215 km/h).[61] On the next day, Erick initiated an eyewall replacement cycle, causing it to begin weakening. Later that day, it was downgraded into a Category 3 hurricane.[62] The following morning, Erick weakened below major hurricane status,[63] then degenerated further into a Category 1 hurricane six hours later.[64] Late on August 1, Erick weakened into a tropical storm due to strong southwesterly wind shear.[65] Erick passed just south of the Big Island of Hawaii before degenerating into a tropical depression late on August 4.[66] At 03:00 UTC on August 5, the storm degenerated into a remnant low. Thus, the CPHC issued their last advisory on the system.[67]

Hurricane FlossieEdit

Category 1 hurricane (SSHWS)
DurationJuly 28 – August 6
Peak intensity80 mph (130 km/h) (1-min)  990 mbar (hPa)

The NHC began to forecast the formation of a low-pressure system on July 22.[68] Several days later, a disturbance formed just south of the coast of Guatemala.[69] As it tracked west-northwestwards, the system encountered favorable conditions and developed a well-defined center of circulation on July 28, leading to its classification as a tropical depression.[70] At 09:00 UTC on July 29, the system strengthened into a tropical storm and was named Flossie.[71] The storm gradually intensified into a Category 1 hurricane on the next day as it moved away from the Mexican coast.[72] Several hours later, Flossie reached it peak intensity with 70 kt (80 mph; 130 km/h) winds. Soon thereafter, it began weakening due to high upper-level winds and resultant shear. At 21:00 UTC on July 31, Flossie weakened back into a tropical storm.[73] At 21:00 UTC on August 2, Flossie moved into the Central Pacific Hurricane Center's area of responsibility as a largely disorganized system.[74] Flossie then slowly approached Hawaii as it weakened into a tropical depression early on August 5,[75] ultimately degenerating into a remnant low at 03:00 UTC on August 6.[76]

Tropical Storm GilEdit

Tropical storm (SSHWS)
DurationAugust 3 – August 5
Peak intensity40 mph (65 km/h) (1-min)  1006 mbar (hPa)

Tropical Storm Gil originated from disorganized thunderstorms noted first on July 29.[77] The system slowly organized over the following days and by 15:00 UTC on August 3 it developed into Tropical Depression Eight-E.[78] Despite unfavorable conditions for further development, six hours after formation, Eight-E strengthened into Tropical Storm Gil.[79][80] However, this would be short-lived as Gil weakened back into a tropical depression by 6:00 UTC August 4.[81] Shortly after 12:00 UTC the same day, Gil became completely devoid of deep convection due to strong wind shear.[82] Finally, at 3:00 UTC August 5, Gil degenerated into a remnant low far off the coast of Mexico.[83]

Tropical Storm HenrietteEdit

Tropical storm (SSHWS)
DurationAugust 12 – August 13
Peak intensity40 mph (65 km/h) (1-min)  1005 mbar (hPa)

On August 5 at 11:00 a.m. PDT, the NHC began to forecast the potential formation of a low-pressure system off the coast of Mexico.[84] A day later, thunderstorms associated with a tropical wave formed in the region.[85] The system struggled to organize due to land interaction. On August 11, it merged with another disturbance to its southwest[86] and quickly intensified as it moved west-northwestwards. On the following day, it developed a closed center of circulation and was classified as Tropical Depression Nine-E as it continued to move towards the west.[87] At 09:00 UTC on August 12, the depression intensified into Tropical Storm Henriette.[88] Henriette maintained its intensity of 40 mph (65 km/h) that day before it weakened into a tropical depression early on August 13 due to the intrusion of dry air and ongoing wind shear.[89] Henriette degenerated into a remnant low several hours later and the NHC issued its last advisory on the system.[90]

Tropical Storm IvoEdit

Tropical storm (SSHWS)
DurationAugust 21 – August 25
Peak intensity65 mph (100 km/h) (1-min)  992 mbar (hPa)

On August 12, the NHC forecast the potential formation of a tropical disturbance well of the coast of Mexico.[91] The disturbance failed to organize until August 16 at around 21:00 UTC when a broad low-pressure system formed within the area.[92] By 15:00 UTC on August 21, the system organized itself enough to be classified as a tropical depression.[93] It intensified into Tropical Storm Ivo a few hours later.[94] At 15:00 UTC on August 22, Ivo reached peak winds of 65 mph (100 km/h) over open waters, and was forecast to become a minimal hurricane, but unexpected wind shear took its toll on the system.[95] Ivo then moved over cooler waters and gradually began to weaken as deep convection started to separate from its low-level center.[96] Ivo fell to tropical depression intensity around 09:00 UTC on August 25 as the system started being devoid of deep convection.[97] Finally, after being reduced to a swirl of low-level clouds, Ivo was declared a remnant low at 21:00 UTC on August 25.[98] Even though Ivo did not affect land, it brought tropical storm winds to Clarion Island, where sustained winds of 62 mph and gusts to 76 mph were reported.[99]

Hurricane JulietteEdit

Category 3 hurricane (SSHWS)
DurationSeptember 1 – September 7
Peak intensity125 mph (205 km/h) (1-min)  953 mbar (hPa)

On August 30, the NHC started tracking a low-pressure area associated with a tropical wave for potential development of thunderstorms.[100] On the next day, thundershowers formed within the area.[101] The system rapidly organized in the next two days and intensified into Tropical Storm Juliette on September 1.[102] Juliette quickly intensified into a Category 1 hurricane on the next day.[103] Rapid intensification continued and Juliette reached major hurricane status on September 3, peaking as a high-end Category 3 hurricane with winds of 125 mph (205 km/h).[104] After reaching peak intensity, the storm began to weaken due to high wind shear a few hours later and quickly weakened to below major hurricane status on the next day.[105] Weakening continued as the storm moved away from the Mexican coast and the system weakened to a tropical storm on September 6.[106] Finally at 21:00 UTC on September 7, Juliette degenerated into a remnant low.[107]

Tropical Storm AkoniEdit

Tropical storm (SSHWS)
DurationSeptember 4 – September 6
Peak intensity45 mph (75 km/h) (1-min)  1003 mbar (hPa)

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.[108] Just a few hours later, following a sudden increase in convection, the system organized into a tropical depression and moved into the Central Pacific basin.[109] It slowly intensified and eventually reached tropical storm status, whereupon it was named Akoni.[110] The system struggled to organize because of high wind shear and quickly degenerated to a remnant low on September 6.[111]

Late on September 6, the NHC began to forecast the development of an area of low pressure off the coast of Mexico.[112] Within the next few days, a tropical wave developed and slowly organized,[113][114] eventually coalescing into a tropical depression on September 12.[115] Six hours later, it intensified to a tropical storm.[116] The system struggled to intensify due to high wind shear. However, two days later, Kiko began to rapidly intensify, reaching Category 1 hurricane status as conditions became somewhat favorable for intensification.[117] Rapid intensification continued, and later that evening, Kiko reached major hurricane status.[118] At 15:00 UTC on September 15, Kiko intensified further into a Category 4 hurricane, reaching its peak intensity.[119] Twelve hours later, Kiko began to weaken,[120] falling to Category 2 status by 15:00 UTC on September 16.[121]
