The 2014 Pacific hurricane season consisted of the events that occurred in the annual cycle of tropical cyclone formation over the Pacific Ocean north of the equator and east of the International Date Line. The official bounds of each Pacific hurricane season are dates that conventionally delineate the period each year during which tropical cyclones tend to form in the basin according to the National Hurricane Center (NHC), beginning on May 15 in the Eastern Pacific proper (east of 140°W) and June 1 in the Central Pacific (140°W to the International Date Line), and ending on November 30 in both areas. However, tropical cyclogenesis is possible at any time of year. [1] The first tropical cyclone of the season, Hurricane Amanda, developed on May 22; the final, Hurricane Vance, dissipated on November 5.

Contents

On account of several unusually favorable atmospheric and oceanic factors, [2] the 2014 season was one of the most active on record for the basin. It produced twenty-three tropical depressions, of which all but one developed into named tropical storms; sixteen became hurricanes, of which nine further intensified into major hurricanes. [nb 1] [3] All of these parameters exceeded the 1981–2010 averages of 16.5 tropical storms, 8.9 hurricanes, and 4.3 major hurricanes; the number of hurricanes was tied with 1990 and 1992 for the most in one season since reliable records began. [4] The season's activity levels were reflected by an overall Accumulated Cyclone Energy index of 202.4 units, which is the seventh-highest value for a Pacific hurricane season as of July 2024. [nb 2] [6]

Multiple tropical cyclones impacted land or were otherwise notable for meteorological reasons. The season's most impactful was Hurricane Odile in mid-September, [2] which caused extensive damage throughout Baja California Sur after it made landfall near Cabo San Lucas as a strong Category 3 hurricane with maximum sustained winds of 125 mph (205 km/h). It later struck the mainland of northwestern Mexico as a tropical storm, and its remnants generated severe thunderstorms and intense flooding in portions of the Southwestern United States. [7] Odile and its remnants killed more than a dozen people and wrought US$1–1.25 billion in damage, [7] [8] resulting in its name being retired the following spring. [9]

Hurricane Iselle in early August was the strongest recorded tropical cyclone to make landfall on Hawaii's Big Island; torrential rainfall of up to 15.25 in (38.74 cm) caused significant flooding, with damage exacerbated by strong winds. The state of Hawaii incurred at least US$148 million in losses, and one person was killed. [10] Later that month, Hurricane Marie reached Category 5 status and became the seventh-most intense Pacific hurricane on record—tied with Odile—when it reached a barometric pressure of 918 mbar (27.11 inHg). [3] Marie's large size and immense strength produced high surf that drowned four people in the United States and Mexico; damages totaled US$20 million in the former country, [11] while flooding from peripheral rains in the latter caused two additional fatalities. [12] Hurricane Amanda was the strongest Pacific hurricane ever recorded in the month of May, peaking with maximum sustained winds of 155 mph (250 km/h) and a minimum barometric pressure of 932 mbar (27.52 inHg); however, it did not directly affect land. [13]

Prior to 2015, two time zones were utilized in the Eastern Pacific basin: Pacific east of 140°W, and Hawaii−Aleutian from 140°W to the International Date Line. [14] [15] For convenience, each event is listed in Coordinated Universal Time (UTC) first, using the 24-hour clock (where 00:00 = midnight UTC), [16] with the respective local time included in parentheses. Figures for maximum sustained winds and position estimates are rounded to the nearest five units (knots, miles, or kilometers) and averaged over one minute, following National Hurricane Center practice. Direct wind observations are rounded to the nearest whole number. Atmospheric pressures are listed to the nearest millibar and nearest hundredth of an inch of mercury. This timeline documents the formation of tropical cyclones as well as the strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It also includes information that was not released while the storm was active, meaning that data from post-storm reviews by the National Hurricane Center and the Central Pacific Hurricane Center is included.

Notes

  1. A major hurricane is a Pacific or Atlantic hurricane that reaches Category 3 or higher on the five-level Saffir–Simpson scale, with maximum sustained winds of at least 111 mph (179 km/h). [1]
  2. Broadly speaking, Accumulated Cyclone Energy is the square of a tropical cyclone's wind intensity in knots at 6-hour intervals, multiplied by the length of time it existed. [5]
  3. Operationally, advisories were initiated on Tropical Storm Wali at 21:00 UTC (11:00 a.m. HST) on July 17. Wali was not yet believed to have reached tropical storm strength, and the first advisory designated the storm as Tropical Depression One-C; [22] [23] it was upgraded to Tropical Storm Wali one hour later. [24]
  4. On November 2, daylight saving time ended in most areas of the basin, which resulted in the gap between UTC and local time widening by one hour. Hawaii was not affected; the state has not observed daylight saving time since 1945. [39] [40]

<span class="mw-page-title-main">Timeline of the 2004 Pacific hurricane season</span>

The 2004 Pacific hurricane season had 17 tropical cyclones, of which 12 became named storms, 6 became hurricanes, and 3 became major hurricanes. This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation. It also includes information which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned on, have been included. The season officially began on May 15, 2004, in the eastern Pacific proper and lasted until November 30 that same year. Areas east of 140°W are under the purview of the National Hurricane Center (NHC); the area between the International Date Line and 140°W, or the central Pacific, is under the purview of the Central Pacific Hurricane Center (CPHC).

<span class="mw-page-title-main">Timeline of the 2008 Pacific hurricane season</span>

The 2008 Pacific hurricane season officially started 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. The first storm of the year, Tropical Storm Alma, developed on May 29, and the last, Tropical Storm Polo dissipated on November 5.[

<span class="mw-page-title-main">Timeline of the 2010 Pacific hurricane season</span>

The 2010 Pacific hurricane season was one of the least active seasons on record, featuring the fewest named storms since 1977. The season officially started on May 15 in the eastern Pacific—east of 140°W—and on June 1 in the central Pacific—between the International Date Line and 140°W—and lasted until November 30. These dates typically cover the period of each year when most tropical cyclones form in the eastern Pacific basin. The season's first storm, Tropical Storm Agatha, developed on May 29; the season's final storm, Tropical Storm Omeka, degenerated on December 21.

<span class="mw-page-title-main">Timeline of the 1992 Pacific hurricane season</span>

The 1992 Pacific hurricane season was the most active season on record, featuring 27 named storms. The season officially started on May 15, in the Eastern Pacific—designated as the area east of 140°W—and on June 1, in the Central Pacific, which is between the International Date Line and 140°W. The season officially ended in both basins on November 30. These dates typically limit the period of each year when most tropical cyclones form in the eastern Pacific basin. Lasting 24 days, Hurricane Tina became the longest lived North Pacific tropical cyclone on record. Its longevity broke the old record for the Eastern and Central Pacific of 20 days, set by Hurricane Fico in 1978; and the old record for the Western Pacific of 22 days, set by Typhoon Rita in 1972.

<span class="mw-page-title-main">Timeline of the 2011 Pacific hurricane season</span>

The 2011 Pacific hurricane season consisted of the events that occurred in the annual cycle of tropical cyclone formation over the Pacific Ocean north of the equator and east of the International Date Line. The official bounds of each Pacific hurricane season are dates that conventionally delineate the period each year during which tropical cyclones tend to form in the basin according to the National Hurricane Center (NHC), beginning on May 15 in the Eastern Pacific proper and June 1 in the Central Pacific, and ending on November 30 in both areas. However, tropical cyclogenesis is possible at any time of year. The season generated eleven tropical storms, which is below the 1991–2020 average of fifteen. However, all but one became hurricanes and six further strengthened into major hurricanes, eclipsing the 1991–2020 averages of eight hurricanes and four major hurricanes. There were also two tropical depressions that remained below tropical storm status. The first system, Hurricane Adrian, formed on June 7; the final, Hurricane Kenneth, was the latest in a calendar year to exist east of 140°W since 1983, dissipating on November 25.

<span class="mw-page-title-main">Timeline of the 1990 Pacific hurricane season</span>

The 1990 Pacific hurricane season saw a then-record 16 hurricanes form. Throughout the year, 21 tropical cyclones became named storms in the eastern Pacific Ocean. Hurricane Alma formed on May 12, 1990, three days before the season's official start on May 15. The Central Pacific hurricane season began on June 1, covering tropical cyclone formation in the region between 140°W and International Dateline. Hurricane Trudy was the last storm to dissipate, doing so on November 1, nearly a month before the Pacific hurricane season officially ended on November 30.

The season officially started on May 15 in the Eastern Pacific—east of 140°W—and began on June 1 in the Central Pacific—the region between the International Date Line and 140°W–and ended on November 30. These dates typically cover the period of each year when most tropical cyclones form in the Eastern Pacific basin according to the National Hurricane Center. However, tropical cyclones sometimes form outside the bounds of an official season, as was evidenced by the formation of Tropical Depression One-E on April 25. The season effectively ended with the dissipation of its final storm, Tropical Storm Polo, on November 19.

<span class="mw-page-title-main">Timeline of the 2021 Pacific hurricane season</span>

The 2021 Pacific hurricane season was a moderately active hurricane season, with above-average tropical activity in terms of named storms, but featured below-average activity in terms of major hurricanes. It is the first season to have at least five systems make landfall in Mexico, the most since 2018. It was also the second consecutive season in which no tropical cyclones formed in the Central Pacific. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; both ended on November 30. These dates historically describe the period each year when most tropical cyclones form in the eastern and central Pacific and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year, as illustrated this year by the formation of Tropical Storm Andres on May 9. This was the earliest forming tropical storm on record in the Eastern Pacific. The season effectively ended with the dissipation of Tropical Storm Terry, on November 10.

<span class="mw-page-title-main">Timeline of the 2022 Pacific hurricane season</span>

The 2022 Pacific hurricane season was a fairly active tropical cyclone season, with 19 named storm altogether. Ten of those became hurricanes, and four further intensified into major hurricanes. Two of this season's storms, Bonnie and Julia, survived the overland crossover from the Atlantic. The season officially started on May 15 in the eastern Pacific—east of 140°W—and June 1 in the central Pacific—between the International Date Line and 140°W, and ended in both regions on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the eastern Pacific basin. The season's first storm, Agatha, formed on May 28, and last, Roslyn, dissipated on October 23. Rosyln made landfall in Nayarit with 120 mph (195 km/h) winds, making it the strongest landfalling Pacific hurricane since Patricia in 2015. The season's first major hurricane, Bonnie, entered into the basin from the Atlantic basin on July 2, after crossing Nicaragua as a tropical storm, becoming the first storm to survive the crossover from the Atlantic to the Pacific since Otto in 2016. Three months later, Julia became the second to do so.

<span class="mw-page-title-main">Timeline of the 2023 Pacific hurricane season</span>

The 2023 Pacific hurricane season was a fairly active Pacific hurricane season. In the eastern Pacific basin, 17 named storms formed; 10 of those became hurricanes, and 8 further intensified into major hurricanes. In the central Pacific basin, no tropical cyclones formed, though four entered into the basin from the east. The season officially began on May 15, 2023, in the eastern Pacific, and on June 1 in the central Pacific; it ended in both on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of the Pacific. The season's first system, Tropical Storm Adrian, developed on June 27, and its last, Tropical Storm Ramon, dissipated on November 26.

<span class="mw-page-title-main">Timeline of the 1993 Pacific hurricane season</span>

The 1993 Pacific hurricane season consisted of the events that occurred in the annual cycle of tropical cyclone formation over the Pacific Ocean north of the Equator and east of the International Date Line. The official bounds of each Pacific hurricane season are dates that conventionally delimit the period each year during which tropical cyclones tend to form in the basin according to the National Hurricane Center, beginning on May 15 in the Eastern Pacific proper and on June 1 in the Central Pacific, and ending on November 30 in both areas. However, tropical cyclogenesis is possible at any time of the year. The first system, Hurricane Adrian, developed on June 11; the final system, Tropical Depression Seventeen-E, dissipated on October 14.

<span class="mw-page-title-main">Timeline of the 1994 Pacific hurricane season</span>

The 1994 Pacific hurricane season consisted of the events that occurred in the annual cycle of tropical cyclogenesis over the Pacific Ocean north of the Equator and east of the International Date Line. The official bounds of each Pacific hurricane season are dates that conventionally delimit the period each year during which tropical cyclones tend to form in the basin according to the National Hurricane Center, beginning on May 15 in the Eastern Pacific proper and on June 1 in the Central Pacific, and ending on November 30 in both areas. Activity in the 1994 season was considerably greater than average, particularly in the Central Pacific; tropical cyclones generally formed and intensified farther west than normal due in part to above-average sea surface temperatures over the southeastern portion of the Central Pacific and the prevalence of a large anticyclone near 140°W for much of July and August. El Niño conditions, which tend to cause increased tropical cyclone activity over the Pacific Ocean, were also present. Despite the high activity, the season had an unusually late start; it did not commence until the formation of Tropical Storm Aletta on June 18. The season ended on October 26 with the dissipation of Tropical Storm Nona.

<span class="mw-page-title-main">Timeline of the 2024 Pacific hurricane season</span>

The 2024 Pacific hurricane season is the current tropical cyclone season in the Pacific Ocean east of the International Date Line (IDL) in the Northern Hemisphere. It officially began on May 15 in the eastern Pacific, and on June 1 in the central Pacific ; it will end in both on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of the Pacific. The season's first system, Tropical Storm Aletta, developed on July 4.

<span class="mw-page-title-main">Timeline of the 1995 Pacific hurricane season</span>

The 1995 Pacific hurricane season consisted of the events that occurred in the annual cycle of tropical cyclone formation over the Pacific Ocean north of the equator and east of the International Date Line. The official bounds of each Pacific hurricane season are dates that conventionally delineate the period each year during which tropical cyclones tend to form in the basin according to the National Hurricane Center (NHC), beginning on May 15 in the Eastern Pacific proper and June 1 in the Central Pacific, and ending on November 30 in both areas. However, tropical cyclogenesis is possible at any time of year. Activity during the season was below average; only eleven tropical depressions developed, of which ten strengthened into named tropical storms. Seven became hurricanes, of which three further intensified into major hurricanes. Hurricane Barbara was the only tropical cyclone to exist in the Central Pacific in 1995, entering the region as a weak system near dissipation. The first system, Tropical Depression One-E, formed on May 21; the final, Hurricane Juliette, dissipated on September 26, making this season the first since the beginning of the satellite era in which no tropical cyclones were active after September.
