Pacific hurricane seasons
2013, 2014, 2015, Post-2015

The 2015 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 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. Due to a strong El Niño event, the 2015 season is predicted to be an above-average season.

On April 10, 2015, the Servicio Meteorológico Nacional (SMN) issued its first outlook for the Pacific hurricane season, forecasting 19 named storms, 11 hurricanes, and 4 major hurricanes. The organization listed a set of seasons with similar atmospheric and oceanic conditions, including 1982, 1986, 1991, 1994, 2002, and 2014.[3] On May 27, the National Oceanic and Atmospheric Administration's Climate Prediction Center (CPC) released its forecast for the year, highlighting a 70% chance of an above-average season with 15–22 named storms, 7–12 hurricanes, 5–8 major hurricanes, and an Accumulated Cyclone Energy (ACE) index range of 110–190% of the median. While both organizations cited an intensifying El Niño as a result of increased activity, the CPC also highlighted the difference in global sea surface temperature patterns in 2015 versus the 1995–2014 period.[3][4]

The Accumulated Cyclone Energy (ACE) index for the season as of 15:00 UTC on September 08 is 109.6975 units in the East Pacific and 83.8200 units in the Central Pacific. The total ACE in each basin amounted to 193.5175.[nb 1]

The season's first named storm, Andres, developed two weeks after the official start of the season. Andres later reached peak intensity as a Category 4 hurricane on June 1.[5] On June 3, Blanca became both earliest second hurricane and second major hurricane in the basin since reliable records began.[6][7] This broke the previous record set by Hurricane Cristina the previous year which reached major status on June 12, 2014.[8] On June 13, Hurricane Carlos became the second earliest third hurricane on record.[9] After an inactive period for about a month, activity resumed in mid-July with five systems forming in short succession (three in the central Pacific and two in the east Pacific). One of these systems, Tropical Storm Ela, became the third earliest forming Central Pacific storm on record. Tropical Storm Halola crossed the International Date Line two days later. Next month, hurricanes Guillermo and Hilda both affected Hawaii, while Hurricane Loke became the record breaking fifth named storm this year in the Central Pacific. Soon after Loke dissipated, Tropical Storm Kilo strengthened into a hurricane while Ignacio and Jimena were being named. Late on August 29th, all three storms exploded into Category 4 major hurricanes.[citation needed] The three major hurricanes on August 29th were the first time in the historical record that three or more major hurricanes existed simultaneously in the Pacific, east of the International Date Line (180ºW).[10][11] Tropical Storm Kevin formed, but was short-lived, and Kevin and Ignacio dissipated on September 5.

Storms

Hurricane Andres

Category 4 hurricane (SSHWS)
 
DurationMay 28 – June 4
Peak intensity145 mph (230 km/h) (1-min);
937 mbar (hPa)

On May 23, the National Hurricane Center began monitoring the potential for tropical cyclogenesis well south of Mexico over the following days.[12] A large area of disturbed weather formed two days later,[13] steadily organizing to become Tropical Depression One-E at 09:00 UTC on May 28.[14] With an increase in spiral banding and an expanding central dense overcast, the depression was upgraded to Tropical Storm Andres six hours later.[15] Directed west-northwest and eventually northwest by a ridge over Mexico, the cyclone steadily organized despite moderate northerly shear. At 21:00 UTC on May 29, Andres intensified into a Category 1 hurricane,[16] and by 15:00 UTC on May 30, the cyclone further strengthened into a Category 2 hurricane.[17] Although forecasts did not indicate additional strengthening, Andres began a period of rapid deepening the following day, becoming one of only five major hurricanes during the month of May at 21:00 UTC and further intensifying into a Category 4 at 03:00 UTC on June 1.[18][19] Andres ultimately reached its peak intensity early on June 1 with winds of 145 mph (230 km/h).[20] Thereafter, the system moved over cooler waters and into a more stable environment which imparted weakening.[21] Over the next few days, Andres continued to weaken, and by June 3, the NHC determined that it had weakened into a tropical storm.[22] Further weakening ensured, with Andres being designated as a remnant low on June 4.[23]

Moisture extending from the remnants of Andres brought light rain to parts of the Southwest United States, with Phoenix, Arizona having measurable precipitation on June 5 for the first time since records began in 1896.[24] This moisture further extended into Colorado, resulting in scattered severe thunderstorms.[25]

Hurricane Blanca

Category 4 hurricane (SSHWS)
 
DurationMay 31 – June 9
Peak intensity140 mph (220 km/h) (1-min);
943 mbar (hPa)

A tropical wave first monitored by the NHC late on May 27 spawned a weak area of low pressure well south of Acapulco, Mexico two days later.[26][27] Plagued by strong upper-level winds from Hurricane Andres, the disturbance slowly organized into the season's second tropical depression at 22:30 UTC on May 31 and further into Tropical Storm Blanca the following day.[28][29] Moving little within a weak steering regime, the cyclone began rapid deepening by June 2 under favorable conditions aloft; at 21:00 UTC, it was upgraded to a Category 1 hurricane.[6] Following the appearance of a pinhole eye, Blanca was upgraded to a Category 4 hurricane at 15:00 UTC on June 3.[7] Shortly thereafter, Blanca reached its peak intensity as a Category 4 hurricane with winds of 140 mph (220 km/h). Significant upwelling of cooler waters, with some areas falling from 30 to 21 °C (86 to 70 °F),[30] resulted in weakening early on June 4.[31] Its eye quickly collapsed and convection diminished as it underwent an eyewall replacement cycle.[32] Reconnaissance aircraft flew into the storm on June 5 and found Blanca to have degraded to Category 1 status.[33] The next day, Blanca rapidly reintensified and reached its secondary peak as a Category 4 with winds of 130 mph (215 km/h).[34] Thereafter, cooler waters and southeasterly wind shear prompted a weakening phase once more.[35] After weakening to a tropical storm on June 7,[36] Blanca made landfall around 12:00 UTC on June 8, near Puerto Cortés with winds of 45 mph (75 km/h) and became the earliest instance of a landfall in the Baja California peninsula since records began in 1949.[30][37] Thereafter, Blanca weakened to a tropical depression before degenerating into a remnant low early on June 9 as convection diminished.[38][39]

On June 3, precautionary alerts were raised across the southern Baja California Peninsula and much of Western Mexico, due to potential impacts from the hurricane.[40] A collective 3,300 troops from the Mexican Army and Navy were deployed to Baja California Sur to ensure the safety of residents.[41] Waves up to 16 ft (5 m) damaged coastal installations in Puerto Vallarta.[42] Across Baja California Sur, high winds downed power lines and left 104,106 residents without electricity. However, around 90 percent of the outages were fixed within 12 hours of the storm.[43] The remnants of Blanca later brought much-needed rain to parts of Southern California. Daily rainfall records were broken in several areas, though accumulations were generally less than 1 in (25 mm).[44] Some flooding took place in Santa Barbara County.[45]

Hurricane Carlos

Category 1 hurricane (SSHWS)
 
DurationJune 10 – June 17
Peak intensity90 mph (150 km/h) (1-min);
978 mbar (hPa)
Main article: Hurricane Carlos (2015)

Late on June 2, the NHC indicated the potential for an area of disturbed weather to form south of El Salvador and Guatemala over subsequent days.[46] This forecast come to fruition early on June 7, when convection began to increase in association with a trough of low pressure south of the Gulf of Tehuantepec.[47] Steered slowly northwest, the disturbance acquired sufficient organization to be declared a tropical depression at 21:00 UTC on June 10; it was further upgraded to Tropical Storm Carlos at 15:00 UTC the following day.[48][49] Although strong upper-level winds slowed the storm's rate of intensification, the development of a ragged eye on satellite prompted the NHC to upgrade Carlos to a Category 1 hurricane at 15:00 UTC on June 13.[50] However, upwelling of cooler waters generated by the hurricane's slow motion imparted slight weakening.[51] Over the next three days, Carlos fluctuated between strong tropical storm and weak hurricane intensity, before re-intensifying to a strong Category 1 hurricane.[52] However, over the next few hours, Carlos quickly weakened as the environment became unfavorable.[53] By June 17, Carlos had been declared a remnant low.[54]

Strong winds downed several trees and power poles in coastal Guerrero.[55]

Tropical Storm Ela

Tropical storm (SSHWS)
 
DurationJuly 8 – July 10
Peak intensity40 mph (65 km/h) (1-min);
1003 mbar (hPa)

On July 2, the NHC started to monitor a weak tropical disturbance. The system gradually intensified and on July 8, the system intensified into Tropical Depression Four-E as it was located just before entering the area of responsibility of the Central Pacific Hurricane Center.[56] By July 9, the depression intensified into Tropical Storm Ela.[57] After being a tropical storm for 18 hours, Ela was downgraded into a depression early the next day, before being declared a remnant low just six hours later.

Ela is one of just five tropical cyclones to form as a depression in the east Pacific basin but not be named until entering the central Pacific; the others are Lala, Li, Iniki and Lana. It is also the third earliest storm to form during the calendar year in the central Pacific after Ekeka and Hali.[58]

Tropical Storm Halola

Tropical storm (SSHWS)
 
DurationJuly 10 – July 12 (exited basin)
Peak intensity60 mph (95 km/h) (1-min);
999 mbar (hPa)
Main article: Typhoon Halola

A tropical disturbance well to the southwest of Hawaii organized into Tropical Depression One-C by July 10.[59] Early the next day, the system developed into Tropical Storm Halola. On July 12, Halola crossed the International Date Line and entered the Western Pacific basin, the area of responsibility of the Japan Meteorological Agency.[60]

Tropical Storm Iune

Tropical storm (SSHWS)
 
DurationJuly 10 – July 13
Peak intensity40 mph (65 km/h) (1-min);
1003 mbar (hPa)

On July 10, a tropical disturbance organized and became Tropical Depression Two-C. Due to an increase of convection near its centre, the CPHC upgraded the system to Tropical Storm Iune by the next day. But because of its small size and the upper level winds, Iune's circulation became exposed and had weakened to a tropical depression on July 12. By July 13, Iune degenerated to a remnant low as its remnant circulation moved in a slow westward direction.[61] Its remnants continued and reached the International Dateline on July 17.[citation needed]

Hurricane Dolores

Category 4 hurricane (SSHWS)
 
DurationJuly 11 – July 18
Peak intensity130 mph (215 km/h) (1-min);
944 mbar (hPa)

A westward moving tropical wave crossed Central America and entered the Eastern Pacific. On July 11, the system was declared Tropical Depression Five-E. The storm quickly strengthened into Tropical Storm Dolores, and reached hurricane status early on July 13. A day later, Dolores explosively intensified into a Category 4 major hurricane. After Dolores moved over Socorro Island, the cyclone started to steadily weaken. On Friday morning, July 17, it weakened to a tropical storm and degenerated into a post-tropical low-pressure center about 300 miles west of the Baja California coast on Saturday evening, July 18.[62]

Moisture extending from the storm's remnants brought record rains and thunderstorms to Southern California; record monthly rainfall totals include 2 in (51 mm) in San Diego, 1.30 in (33 mm) in Los Angeles, and 1.16 in (29 mm) in Paso Robles. In the foothills and mountains of east San Diego County (e.g. the town of Ramona), rainfall exceeded 4 in (100 mm) [63][64] This had the effect of helping firefighters contain the North Fire,[65] but also washed out a bridge along Interstate 10.[66]

Tropical Storm Enrique

Tropical storm (SSHWS)
 
DurationJuly 12 – July 18
Peak intensity50 mph (85 km/h) (1-min);
1000 mbar (hPa)

On July 12, a tropical disturbance was upgraded to Tropical Depression Six-E. The storm slowly became Tropical Storm Enrique. Situated in an unfavorable environment, Enrique struggled to intensify. The system reached its peak with 50 mph (85 km/h) winds on July 15. Thereafter, cool waters and stable air took their toll and constrained convection. Despite these conditions, Enrique was able to maintain minimal tropical storm intensity until the next day. Enrique was downgraded into a depression Thursday afternoon, July 16, but was reupgraded into a tropical storm early the next morning. During the afternoon of July 17, Enrique was downgraded into a depression again, before being declared a remnant low later that evening. Throughout its lifetime, Enrique never affected land.[67] The remnants re-curved eastward over the next two days.[68]

Tropical Storm Felicia

Tropical storm (SSHWS)
 
DurationJuly 23 – July 25
Peak intensity40 mph (65 km/h) (1-min);
1004 mbar (hPa)

On July 19, a tropical wave was monitored for possible development. The system struggled to organize and ended up moving over colder water, lowering the chance for development. On July 23, the system was organized enough to be named Tropical Storm Felicia and maintained weak tropical storm status, before weakening into a depression and later a remnant low on July 25. Felicia did not directly impact any land areas, but its effects were felt in Baja California Peninsula.[citation needed]

Tropical Depression Eight-E

Tropical depression (SSHWS)
 
DurationJuly 27 – July 30
Peak intensity35 mph (55 km/h) (1-min);
1007 mbar (hPa)

A low pressure area formed in the middle of the Eastern Pacific. Moving northwest, the low slowly intensified into Tropical Depression Eight-E on July 27. Despite forecast to attain tropical storm strength by the 29th, another tropical wave quickly formed into Tropical Storm Guillermo. Guillermo then rapidly intensified, brought upper level winds over the smaller depression, and eventually caused it to degenerate into a remnant low on July 30. Eight-E's remnants continued tracing in a westward direction, crossed the basin and reached the International Dateline on August 5.[citation needed]

Hurricane Guillermo

Category 2 hurricane (SSHWS)
 
DurationJuly 29 – August 7
Peak intensity105 mph (165 km/h) (1-min);
970 mbar (hPa)

A tropical disturbance gained enough organization to be declared Tropical Storm Guillermo during the early hours of July 30. Over the next two days, Guillermo strengthened into a Category 2 hurricane. As it moved closer to Hawaii, it started to gradually weaken and by August 3 it was downgraded to a tropical storm.[citation needed] On August 6, some of Guillermo's moisture traveled to Northern California and the San Francisco Bay Area to bring rare dry lightning storms to those areas during the night.[69] By August 7, Guillermo had weakened into a depression, and was declared a remnant low by the Central Pacific Hurricane Center later that same day.[citation needed]

Hurricane Hilda

Category 4 hurricane (SSHWS)
 
DurationAugust 5 – August 13
Peak intensity140 mph (220 km/h) (1-min);
946 mbar (hPa)

A tropical wave behind Guillermo gained enough organization to be declared Tropical Depression Ten-E. On August 6 the storm was upgraded into Tropical Storm Hilda, which was then upgraded into a hurricane early on August 7 when Hurricane Guillermo dissipated. It then crossed over into the Central Pacific and intensified into a major hurricane. Soon after peaking, Hilda began a slow weakening into a tropical depression.[citation needed]

Tropical Depression Eleven-E

Tropical depression (SSHWS)
 
DurationAugust 16 – August 18
Peak intensity35 mph (55 km/h) (1-min);
1003 mbar (hPa)

A low air pressure system organized into Tropical Depression Eleven-E on August 16.[70] Moving west-northwestwards into an area of unfavorable conditions, the system failed to further intensify and eventually dissipated on August 18.[71]

Hurricane Kilo

Category 4 hurricane (SSHWS)
 
DurationAugust 20 – September 1 (Exited basin)
Peak intensity140 mph (220 km/h) (1-min);
940 mbar (hPa)

On August 20, a low pressure area south of Hawaii became Tropical Depression Three-C. The storm quickly strengthened into Tropical Storm Kilo and continued strengthening. The storm became a strong tropical storm, and despite being in a favorable environment, Kilo weakened into a Tropical Depression on August 23. The storm would remain at tropical depression strength for the next three days.[72] Despite its instability, Kilo's large-scale circulation brought enhanced moisture into Hawaii, leading to locally heavy rainfall in that state. After nearby Hurricane Loke moved north and dissipated on August 26, Kilo was able to restrengthen into a tropical storm. Intensification resumed the next day, with Kilo reaching hurricane strength. By August 29, Kilo had rapidly intensified into a major hurricane, as the storm neared the International Date Line. Kilo peaked in intensity on August 30 as a Category 4 hurricane with winds of 140 miles per hour and a minimum central pressure of 940 millibars. Kilo was also one of three simultaneous major hurricanes east if the International Dateline along with Ignacio and Jimena, the first such occurrence in recorded history.[73][74] After peaking in strength, Kilo fluctuated between Category 3 and 4 strength as it slowly moved northwest, before slowly weakening below major hurricane status as conditions became less favorable. It crossed the dateline early on September 1, becoming Typhoon Kilo.[75] Typhoon Kilo continued on to become one of the longest lived tropical cyclones on record, with a lifespan of 22 days, just over 3 weeks.[76]

Hurricane Loke

Category 1 hurricane (SSHWS)
 
DurationAugust 21 – August 26
Peak intensity75 mph (120 km/h) (1-min);
985 mbar (hPa)

A tropical disturbance near the International Dateline developed into Tropical Depression Four-C on August 21. Moving in an erratic northerly motion, the depression intensified into Tropical Storm Loke. Loke was upgraded to a minimal hurricane as it passed over the Papahānaumokuākea Marine National Monument. Soon after, Loke began accelerated north-northwestward as it neared the International Date Line. Loke became extratropical late on August 26 as it crossed the basin.[citation needed]

Hurricane Ignacio

Category 4 hurricane (SSHWS)
 
DurationAugust 25 – September 5
Peak intensity145 mph (230 km/h) (1-min);
942 mbar (hPa)

On August 25, a low-pressure system formed and organized to Tropical Depression Twelve-E, before strengthening into Tropical Storm Ignacio. Ignacio initially moved west-northwest, posing a threat to Hawaii. On August 26, Ignacio became a Category 1 hurricane, while continuing it's trek towards Hawaii. Over the next few days, Ignacio struggled to intensify while being impacted my moderate wind shear.[77] As wind shear relaxed, Ignacio was able to quickly intensify to major hurricane status on August 29, attaining winds of 115 miles per hour. At this time, the Big Island of Hawaii was placed under a Tropical Storm Watch, as the island began feeling the effects of high surf. [78] Ignacio continued to rapidly intensify, attaining peak intensity at Category 4 status with winds of 145 miles per hour and a minimum central pressure of 942 millibars on August 30.[79] Ignacio was also one of three simultaneous Category 4 hurricanes east of the International Dateline along with Kilo and Jimena, the first such occurrence in recorded history.[80][81] After peaking in intensity, Ignacio began weakening after moving into a less favorable environment. While weakening, Ignacio passed to the north of the Hawaii island chain, causing only minimal impacts. The storm weakened to tropical storm strength on September 1, but was able to reattain hurricane status. This would repeat once again, before the storm weakened to a tropical storm for the last time, and became post-tropical six hours later.[82] The remnants of Ignacio continued north across the Pacific, before turning to the northeast towards Canada. On September 8, the extratropical remnants of Ignacio moved onshore in British Columbia, bringing only light rain and few clouds.[83][84]

Hurricane Jimena

Category 4 hurricane (SSHWS)
 
DurationAugust 26 – September 10
Peak intensity150 mph (240 km/h) (1-min);
936 mbar (hPa)

An area of low pressure well southwest of the coast of Mexico organized to form Tropical Depression Thirteen-E on August 26.[85] On August 27, Thirteen-E strengthened into Tropical Storm Jimena.[86] Located in a favorable environment with low wind shear, abundant moisture and sea surface temperatures (SSTs) of 30°C, Jimena rapidly strengthened into a Category 1 hurricane on August 28.[87][88] Rapid intensification continued, and Jimena was upgraded to a Category 4 major hurricane the next day and reached its peak intensity of 936 millibars, making the strongest storm within the basin this year, ahead of Andres. On the 2:00 p.m. PDT advisory of August 29, Jimena's eye collapsed. This is most likely to be the first stage of an eyewall replacement cycle. As a result, the storm weakened. On the 2:00pm PDT advisory on August 30, Jimena started to re-strengthen. The re-strengthening brought Jimena back to winds of 150 mph, however soon after the storm underwent a faster weakening trend as it began to turn northwest. Early on September 10, Jimena finally degenerated to a post-tropical remnant low.[citation needed]

With Jimena active in a total of 16 days, Jimena is one of the top-10 long lasting tropical cyclones within the basin.[citation needed]

Tropical Storm Kevin

Tropical storm (SSHWS)
 
DurationAugust 31 – September 5
Peak intensity60 mph (95 km/h) (1-min);
998 mbar (hPa)

On August 31, a disturbance developed east of Central America and classified as invest "97E". Over the next 2 days, the disturbance intensified into a tropical depression, acquiring the designation 14E from the NHC. On September 3, the depression developed into Tropical Storm Kevin. Despite heavy wind shear, the storm managed to strengthen to achieve peak winds of 60 mph, higher then forecast. However, a couple days later the wind shear finally took it's toll and on September 5, the storm weakened into a tropical depression and a remnant low shortly thereafter, so the NHC issued its final advisory later that day. Some remnant moisture from Kevin traveled to the Desert Southwest states and enhanced the monsoon.[citation needed]

Hurricane Linda

Category 3 hurricane (SSHWS)
 
DurationSeptember 6 – September 10
Peak intensity125 mph (205 km/h) (1-min);
951 mbar (hPa)

Early in September, a cluster of clouds began to organize into a tropical system. At 3:00 UTC on September 6, they organized enough to be called tropical depression Fifteen-E.[89] Twelve hours later, the depression organized enough to be classified as a tropical storm and was given the name Linda.[90] Linda rapidly strengthened as it moved on a northwestward course and became a hurricane just twelve hours after becoming a tropical storm due to large amounts of deep convection forming around the center.[91] Linda then became a Category 2 hurricane. After a brief period of weakening to a Category 1 hurricane, Linda again rapidly intensified, this time to a Category 3 major hurricane.[92] Less then a day after becoming a major hurricane, Linda rapidly weakened due to increasing wind shear and decreasing water temperatures, becoming a remnant low less then a week after forming.[93]

Monsoonal moisture pulled north from Linda brought thunderstorms to portions of California. Flooding and rock slides prompted numerous road closures. One person drowned in the San Bernardino National Forest.[94][95]
