The 2018 Pacific hurricane season is an ongoing event in the annual cycle of tropical cyclone formation. The season officially began on May 15 in the eastern Pacific, and on June 1 in the central Pacific; they will both end on November 30.[1] These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin, as illustrated when the first tropical depression formed on May 10. The first named storm of the season, Hurricane Aletta, formed on June 6. Hurricane Bud formed three days later and made landfall in Baja California Sur. Tropical Storm Carlotta stalled offshore the Mexican coastline causing minor damage. Hurricane Hector became the strongest storm of the season and the first tri-basin crosser since 2014.

On May 24, 2018, the National Oceanic and Atmospheric Administration released its annual forecast, predicting a 80% chance of a near- to above-average season in both the Eastern and Central Pacific basins, with a total of 14–20 named storms, 7–12 hurricanes, and 3–7 major hurricanes.[4] On May 25, the Servicio Meteorológico Nacional (SMN) issued its first forecast for the season, predicting a total of 18 named storms, 6 hurricanes, and 4 major hurricanes to develop.[5]

Seasonal summary

Hurricane Lane (2018) Hurricane Hector (2018) Tropical Storm Carlotta (2018) Hurricane Bud (2018) Saffir–Simpson scale
Four tropical cyclones active on August 7: Hector (left), Kristy (middle), John (right), and Ileana (merging with John on the right).

The Accumulated Cyclone Energy index for the 2018 Pacific hurricane season, as of 03:00 UTC August 19, is 119.6 units (77.1925 units for the eastern Pacific and 42.4075 units for the central Pacific).[nb 1]

The 2018 season began with the formation of Tropical Depression One-E on May 10, five days prior to the official start. June was an extraordinarily active month in the basin, breaking the record for number of tropical cyclones (six), as well as tying the records for number of named storms (five) and major hurricanes (two).[6] Fabio's intensification into a tropical storm on July 1 marked the earliest date of a season's sixth named storm, beating the previous record of July 3 set in both 1984 and 1985.[7] Activity abruptly slowed thereafter, with only three tropical cyclones forming during the month of July,[8] one of which continued on to intensify into Hurricane Hector in August, which became the third major hurricane of the season. In August, activity increased drastically, with Tropical Storm Ileana and Hurricane John forming just a day apart on August 4 and August 5, respectively, followed by Tropical Storm Kristy two days later. Hurricane Lane formed in mid-August and became the fourth category 4 of the season.[citation needed]

Systems

Tropical Depression One-E

Tropical depression (SSHWS)
01E 2018-05-11 2100Z.jpg One-E 2018 track.png
Duration May 10 – May 11
Peak intensity 35 mph (55 km/h) (1-min)  1007 mbar (hPa)

In early May, a westward-tracking trough or tropical wave embedded in the monsoon trough interacted with a convectively-coupled Kelvin wave. This interaction led to a large area of shower and thunderstorm activity well southwest of Mexico,[9] which the National Hurricane Center began monitoring for tropical cyclone formation on May 7.[10] The disturbance organized over the next 48 hours but lacked a well-defined center needed for classification;[11] by late on May 9, environmental conditions were becoming less favorable for development.[12] In spite of this, an increase in convection and formation of a well-defined circulation led to the designation of the season's first tropical depression at 21:00 UTC on May 10.[13] The system failed to intensify after formation and, owing to strong westerly wind shear, ultimately degenerated into a remnant low by 18:00 UTC on May 11.[14]

Hurricane Aletta

Category 4 hurricane (SSHWS)
Aletta 2018-06-08 1825Z.jpg Aletta 2018 track.png
Duration June 6 – June 11
Peak intensity 140 mph (220 km/h) (1-min)  943 mbar (hPa)

A tropical wave departed western Africa on May 22, moving inconspicuously across the Atlantic and failing to develop convection until it was south of the Gulf of Tehuantepec on June 3. Following the formation of a well-defined center, the system was upgraded to a tropical depression around 00:00 UTC on June 6. It intensified into Tropical Storm Aletta six hours later. Subtropical ridging over the United States directed the system west-northwest, while ideal environmental conditions allowed Aletta to reach hurricane strength around 18:00 UTC on June 7. A period of rapid deepening ensued shortly thereafter, with maximum winds increasing from 75 mph (120 km/h) to 140 mph (220 km/h) within an 18-hour period.[15] At peak, the hurricane was characterized by a distinct eye embedded within cloud tops colder than -70 °C (-94 °F).[16] A track into cooler waters and a more stable air mass caused Aletta to weaken as quickly as it intensified, falling from Category 4 strength to a tropical storm within 30 hours. After losing its associated deep convection, the system degenerated to a remnant low around 12:00 UTC on June 11. The low meandered for several days, before dissipating early on June 16.[15]

Hurricane Bud

Category 4 hurricane (SSHWS)
Bud 2018-06-11 2024Z.jpg Bud 2018 track.png
Duration June 9 – June 15
Peak intensity 130 mph (215 km/h) (1-min)  948 mbar (hPa)

A broad area of disturbed weather formed west of Costa Rica on June 5 in association with a westward-moving tropical wave.[17] Gradual organization occurred as the wave tracked generally westward across the eastern Pacific Ocean. On June 9, the disturbance developed a well-defined surface circulation, leading to the classification of a tropical depression at 21:00 UTC.[18] Six hours later, the depression strengthened into Tropical Storm Bud.[19] A mid-level ridge to the storm's north directed it on a northwest heading for several days,[20] while favorable environmental conditions led to rapid intensification. Bud attained hurricane strength by 21:00 UTC on June 10,[21] and continued intensification up to its peak as a Category 4 hurricane with winds of 130 mph (215 km/h) around 06:00 UTC on June 12.[22] The effects of cold water upwelling prompted a rapid weakening trend shortly after peak, with Bud falling to a tropical storm by 12:00 UTC on June 13.[23] It made landfall near Cabo San Lucas with winds of 45 mph (75 km/h) shortly after 00:00 UTC on June 15 before progressing into the Gulf of California,[24] where it ultimately degenerated to a remnant low around 21:00 UTC that day.[25]

Tropical Storm Carlotta

Tropical storm (SSHWS)
Carlotta 2018-06-16 2001Z.jpg Carlotta 2018 track.png
Duration June 14 – June 19
Peak intensity 65 mph (100 km/h) (1-min)  997 mbar (hPa)

A broad area of low pressure formed south of Mexico on June 12,[26] organizing into the season's fourth tropical depression by 21:00 UTC on June 14 and further into Tropical Storm Carlotta around 18:00 UTC on June 15.[27][28] Initial forecasts showed the storm only slightly intensifying before moving ashore the coastline of Mexico;[29] instead, Carlotta stalled just offshore and strengthened to attain peak winds of 65 mph (100 km/h) as it established an inner core and eye.[30] Interaction between the system's eyewall and land prompted a swift weakening trend as it paralleled the Mexican shoreline, and Carlotta fell to tropical depression intensity by 18:00 UTC on June 17, before degenerating to a remnant low around 03:00 UTC on June 19.[31][32]

Tropical Storm Daniel

Tropical storm (SSHWS)
Daniel 2018-06-24 1830Z.jpg Daniel 2018 track.png
Duration June 24 – June 26
Peak intensity 45 mph (75 km/h) (1-min)  1003 mbar (hPa)

Late on June 21, the NHC began monitoring a surface trough and its associated disorganized convection several hundred miles southwest of Baja California. Environmental conditions were expected to be marginally conducive for development as it moved north-northwest.[33] Convection began to show signs of organization early on June 23,[34] and this process led to the formation of a tropical depression by 03:00 UTC on the next morning, as spiral bands wrapped into the storm's well-defined center.[35] At 15:00 UTC on June 24, the depression was upgraded to a tropical storm and was assigned the name Daniel.[36] At 18:00 UTC on June 24, Tropical Storm Daniel reached peak intensity with sustained winds of 45 mph.[37] At 15:00 UTC on June 25, Daniel began to weaken as it moved over seas cooler than 25 °C (77 °F).[38] The system weakened to a tropical depression at 18:00 UTC that day.[39] At 15:00 UTC on June 26, Daniel degenerated into a remnant low, as it lost all convection and was reduced to a swirl of low-level clouds.[40]

Tropical Storm Emilia

Tropical storm (SSHWS)
Emilia 2018-06-29 2100Z.jpg Emilia 2018 track.png
Duration June 27 – July 2
Peak intensity 60 mph (95 km/h) (1-min)  997 mbar (hPa)

On June 23, the NHC noted the potential for tropical cyclogenesis from a tropical wave crossing over Costa Rica. Environmental conditions were expected to be conducive for development as it moved westward.[41] The system then steadily organized over warm waters and formed into Tropical Depression Six-E at 21:00 UTC June 27, about 480 miles (770 km) southwest of Manzanillo, Mexico.[42] It gradually strengthened into Tropical Storm Emilia at 09:00 UTC on June 28.[43] Near 21:00 UTC on June 29, Emilia reached its peak intensity, with winds of 60 mph (95 km/h); however, it was subject to strong wind shear.[44] The shear took its toll on Emilia, and by 15:00 UTC the next day, it weakened into a tropical depression.[45] Finally, at 03:00 UTC on July 2, Emilia degenerated into a remnant low, as it lost its convection and was reduced to a swirl of clouds.[46]

Hurricane Fabio

Category 2 hurricane (SSHWS)
Fabio 2018-07-03 2050Z.jpg Fabio 2018 track.png
Duration June 30 – July 6
Peak intensity 110 mph (175 km/h) (1-min)  964 mbar (hPa)

The NHC first noted the potential for tropical cyclogenesis from a tropical wave crossing over Honduras and Nicaragua at 18:00 UTC on June 24.[47] Subsequent development was expected of the system as it moved westward. It steadily organized over warm waters and transitioned into Tropical Depression Seven-E at 21:00 UTC June 30, 490 miles (790 km) southwest of Acapulco, Mexico.[48] The system gradually strengthened into Tropical Storm Fabio at 09:00 UTC on July 1.[49] With SSTs of 30 °C (86 °F) and almost no wind shear, Fabio began to intensify, quickly strengthening into a hurricane by 15:00 UTC on July 2.[50] Initially, forecasters at the NHC predicted that Fabio would intensify further and become a major hurricane, although it failed to do so and peaked with maximum sustained winds of 110 mph (175 km/h), just shy of major hurricane status.[51] Afterward, Fabio began to rapidly weaken as it moved over cooler waters. At 15:00 UTC on July 6, Fabio degenerated into a remnant low as it lost its convection while located 1,285 miles (2,065 km) off the coast of the Baja Peninsula.[52]

Tropical Storm Gilma

Tropical storm (SSHWS)
Gilma 2018-07-27 1915Z.jpg Gilma 2018 track.png
Duration July 26 – July 29
Peak intensity 40 mph (65 km/h) (1-min)  1006 mbar (hPa)

On July 18, the NHC forecast the development of an area of low pressure over the east Pacific Ocean within the next few days.[53] A weak area of low pressure developed several hundred miles south-southeast of the Gulf of Tehuantepec on July 22. Little development occurred over the next few days as the low moved northwestward across the Pacific Ocean. However, shower and thunderstorm activity associated with the low began to quickly organize on July 26, leading to the classification of a tropical depression at 21:00 UTC on July 26.[54] At 09:00 UTC the following day, the depression strengthened into Tropical Storm Gilma.[55] However, northwesterly wind shear soon exposed the center of circulation, causing Gilma to weaken to a tropical depression just twelve hours later.[56] At 21:00 UTC on July 29, the system degenerated into a remnant low as it had lacked organized deep convection for 12 hours.[57]

Tropical Depression Nine-E

Tropical depression (SSHWS)
09E 2018-07-26 2230Z.jpg Nine-E 2018 track.png
Duration July 26 – July 27
Peak intensity 35 mph (55 km/h) (1-min)  1008 mbar (hPa)

The NHC began monitoring a disorganized area of low pressure in the deep tropical Pacific Ocean on July 24 for tropical cyclone development.[58] Gradual organization ensued as the low moved westward, and by July 26, it had organized sufficiently to be classified as a tropical depression.[59] The tropical depression failed to organize, however, and the center soon became difficult to locate on satellite imagery.[60] After having lasted less than a day as a tropical cyclone, the depression opened up into a trough, as it became embedded within the Intertropical Convergence Zone at 12:00 UTC on July 27.[61]

Hurricane Hector

Category 4 hurricane (SSHWS)
Hector 2018-08-06 2255Z.jpg Hector 2018 track.png
Duration July 31 – August 13 (Exited basin)
Peak intensity 155 mph (250 km/h) (1-min)  936 mbar (hPa)

Late on July 26, the NHC noted the development of an area of low pressure that was forecast to form a couple hundred miles west-southwest of Mexico.[62] A broad area of low pressure formed several hundred miles south-southeast of Acapulco, Mexico, at 12:00 UTC on July 28.[63] The system gradually developed into a tropical depression at 21:00 UTC on July 31.[64] The depression quickly organized, developing a more defined center and spiral banding, and at 03:00 UTC on August 1, it strengthened into Tropical Storm Hector.[65] Hector further strengthened and became a hurricane at 14:00 UTC on August 2.[66] Afterward, the small hurricane rapidly strengthened, becoming a strong Category 2 hurricane just six hours later.[67] However, the eye became clouded and ill-defined shortly afterward, and Hector's intensification halted momentarily, as northeasterly shear and dry air impinged on the system, weakening the system back to a Category 1 hurricane.[68] However, the hurricane quickly intensified yet again, and restrengthened back into a Category 2 hurricane, and later to a Category 3 hurricane, making it the third major hurricane of the season. A strong convective band soon wrapped into Hector's central dense overcast (CDO), strengthening it to a Category 4 major hurricane.[69] The next morning, a shrinking CDO weakened Hector back into a Category 3 storm.[70] In the following hours Hector underwent an eyewall replacement cycle and was set to weaken thereafter. However, after the completion of the eyewall replacement cycle, Hector rapidly intensified back to a high-end Category 4 storm on August 6. At 09:00 UTC on August 8, Hector weakened to a category 3 hurricane. At 21:00 UTC, the CPHC reported that Hector was passing about 200 miles (320 km) south of the Big Island with winds of 115 mph. At the same time, Hector began the third eyewall replacement cycle. By 09:00 UTC on August 9, Hector completed the eyewall replacement cycle. By 15:00 UTC on the same day, Hector began to intensify once again as it moved due west. At 21:00 UTC on August 10, Hector reached its secondary peak intensity with winds of 140 mph (220 km/h) as it began to turn west-northwest. On August 11, Hector began another weakening trend as increasing wind shear began to take a toll on the system. By this time, the hurricane set a record for the longest consecutive duration as a major hurricane in the northeastern Pacific. Late on August 11, Hector weakened below major hurricane strength due to increasing wind shear, a status it had held for nearly eight days. Hector weakened to Category 1 status on August 12. On August 13 at 15:00 UTC, Hector crossed the International Date Line as a tropical storm.

Tropical Storm Ileana

Tropical storm (SSHWS)
Ileana 2018-08-05 1725Z.jpg Ileana 2018 track.png
Duration August 4 – August 7
Peak intensity 65 mph (100 km/h) (1-min)  998 mbar (hPa)

A tropical wave entered the eastern Pacific Ocean on August 3, where the NHC began to monitor the system for tropical development.[71] Although the system was initially disorganized, it rapidly organized over the next two days, and on August 4 it developed into a tropical depression while located south of the Gulf of Tehuantepec.[72] The depression continued to organize that night through the next day, and at 21:00 UTC on August 5, the system strengthened into Tropical Storm Ileana.[73] After strengthening to peak winds of 65 mph (100 km/h), Ileana weakened as it began to feel the influence of the much larger Hurricane John. On August 7, the small circulation of Ileana dissipated, as the storm was absorbed by John.[74]

Heavy rain in Guerrero resulted in three deaths, while rip currents caused an additional fatality along the coast of Acapulco.[75]

Hurricane John

Category 2 hurricane (SSHWS)
John 2018-08-07 2030Z.jpg John 2018 track.png
Duration August 5 – August 10
Peak intensity 105 mph (165 km/h) (1-min)  969 mbar (hPa)

On July 29, the NHC began forecasting the development of an area of low pressure that was expected to form several hundred miles off the Mexican coast.[76] A broad area of low pressure formed several hundred miles south of the Gulf of Tehuantepec on August 2.[77] Gradual organization occurred as the low moved slowly west-northwestward, and at 21:00 UTC on August 5, the low had organized sufficiently to be classified as the season's twelfth tropical depression.[78] The depression quickly strengthened into Tropical Storm John six hours later.[79] Amid very favorable environmental conditions, John rapidly intensified, and by 21:00 UTC on August 6, John had become the fifth hurricane of the season, and soon began to interact with Tropical Storm Ileana to the east.[80] On August 7, Hurricane John absorbed the smaller Tropical Storm Ileana, while continuing to strengthen.[74] At 15:00 UTC August 7, John reached peak intensity with winds of 105 mph (165 km/h).[81] However, John began to move over cooler waters and began to weaken. The cyclone fell to a Category 1 by 15:00 UTC August 8, and to tropical storm status by 09:00 UTC August 9, until it finally degenerated into a remnant low at 15:00 UTC on August 10.[82]

Although John never made landfall, it produced high surf along the coastlines of Baja California and Southern California.[83]

Tropical Storm Kristy

Tropical storm (SSHWS)
Kristy 2018-08-10 1925Z.jpg Kristy 2018 track.png
Duration August 7 – August 11
Peak intensity 70 mph (110 km/h) (1-min)  991 mbar (hPa)

An area of disturbed weather formed south of Mexico on August 2,[84] the NHC began monitoring the disturbance for potential tropical development. The system lingered for days without developing as it tracked generally towards the west, until it gained enough organization to be classified as Tropical Depression Thirteen-E at 05:00 UTC on August 7.[85] The depression eventually developed into Tropical Storm Kristy at 09:00 UTC later that day.[86] Kristy gradually strengthened over the next few days, and at 03:00 UTC on August 10, it attained its peak intensity with maximum sustained winds of 70 mph (110 km/h), just short of hurricane status.[87] As Kristy moved over cooler waters, it gradually weakened, until it degenerated into a remnant low at 15:00 UTC on August 11.[88]

Tropical Depression Fourteen-E quickly organized and formed on August 15, approximately 1,115 miles (1,795 km) off the coast of Baja California.[89] Within hours, the system quickly intensified into Tropical Storm Lane and at 03:00 UTC on August 17, Lane strengthened into a hurricane. Shortly after, Lane began to undergo rapid intensification, becoming a Category 2 hurricane at 15:00 UTC later that day. Lane further strengthened into a Category 3 hurricane at 03:00 UTC on August 18, becoming the fourth major hurricane of the season. Soon afterward, Lane intensified into a Category 4 hurricane at 09:00 UTC on the same day, with winds of 140 mph (220 km/h). At 09:00 UTC on August 19, Lane was downgraded back to a Category 3 hurricane. But on 21:00 UTC on August 20, Lane re-intensified back to Category 4 status.
