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 (east of 140°W) and on June 1 in the Central Pacific (140°W to the International Date Line), and ending on November 30 in both areas.[2] 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.[3] El Niño conditions, which tend to cause increased tropical cyclone activity over the Pacific Ocean, were also present.[4] Despite the high activity, the season had an unusually late start;[5] 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.

A total of twenty-two tropical depressions formed, with all but two strengthening into named tropical storms; ten became hurricanes, of which five became major hurricanes (Category 3 or higher on the Saffir–Simpson scale).[3][6] Three hurricanes – Emilia, Gilma, and John – reached Category 5 intensity, the highest rating on the scale. This set a record for most Category 5 hurricanes in one season since records began in 1971, which would later be tied in 2002 and 2018.[7] Hurricane John traversed the Pacific Ocean for 8,190 miles (13,180 km), making it the farthest-traveling tropical cyclone on record worldwide.[8][9] Lasting for thirty days,[nb 2] John was also the longest-lived tropical cyclone on record globally until Cyclone Freddy, which spent at least thirty-four days as a tropical cyclone in February and March 2023.[11][12][13] The storms of the 1994 season collectively generated an Accumulated Cyclone Energy index of 185.2 units, which is the eleventh-highest on record for a Pacific hurricane season as of March 2024.[nb 3][15]

Only one tropical cyclone, Hurricane Rosa in October, caused fatalities or made landfall during the 1994 season. It struck the Mexican state of Sinaloa at Category 2 strength, killing five people in the country.[3] Proceeding rapidly northeastward across Mexico and into the United States after landfall, the storm and its remnants caused disastrous flooding in southeastern Texas that claimed more than twenty lives and wrought at least $700 million (1994 USD) in damage.[16] Earlier in the season, Tropical Depression One-C and Hurricane John caused minor impacts in the Central Pacific. Heavy rainfall from One-C generated substantial flooding on the Big Island of Hawaii, resulting in damages estimated at up to $5 million (1994 USD).[6] After weakening greatly from its peak intensity, John passed about 15 mi (30 km) to the north of Johnston Atoll as a strong Category 1 hurricane; high winds caused $15 million (1994 USD) in damage.[6]

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.[17][18] For convenience, each event is listed in Coordinated Universal Time (UTC) first, using the 24-hour clock (where 00:00 = midnight UTC),[19] 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.

A track map of a hurricane over much of the Pacific Ocean. It is generally westward at first, except for two brief northwest turns early in the system's life. It then gradually curves into a more prolonged northwestward motion, which ends with an abrupt turn to the east as it slows down greatly. A hairpin turn results in the system resuming a northwestward trajectory; finally, it turns northeastward and accelerates, meeting its demise over the far northern Central Pacific basin.

November

  • No tropical cyclones were active in November.

November 30

  • The 1994 Pacific hurricane season officially ends.[2]

Notes

  1. ^ Hurricane John was a tropical cyclone for longer than 18.75 days. It crossed the International Date Line on August 28 and entered the Western Pacific basin, where it spent 11.25 days before crossing back into the Central Pacific basin, giving it a total of 30 days as a tropical cyclone.[1]
  2. ^ While the National Hurricane Center stated in their preliminary report on Hurricane John that the system was a tropical cyclone for 31 days,[10] the Eastern and Central Pacific hurricane database (HURDAT) lists 121 data points at six-hour intervals for John, including one for the storm's extratropical transition, for a total of 30 days as a tropical cyclone.[1]
  3. ^ Broadly speaking, Accumulated Cyclone Energy is the square of a tropical cyclone's wind intensity in knots at six-hour intervals, multiplied by the length of time it existed.[14]
  4. ^ In their post-storm reports on Hurricane Emilia, the National Hurricane Center and the Central Pacific Hurricane Center disagreed on the system's maximum wind intensity. The Central Pacific Hurricane Center's report on all 1994 tropical cyclones in their area of responsibility stated that Emilia reached Category 5 intensity at 18:00 UTC on July 19.[6] However, the National Hurricane Center's Premilinary Report on the storm stated that it reached peak winds of 155 mph (250 km/h) – a high-end Category 4 hurricane – at 06:00 UTC on July 19, and maintained these winds for nearly two days.[27][28] The National Hurricane Center has since amended HURDAT to list Emilia as a Category 5 hurricane for six hours starting at 18:00 UTC on July 19.[1]
  5. ^ The Central Pacific Hurricane Center stated in their post-season report that Hurricane Emilia regained Category 5 status at 12:00 UTC on July 20 and maintained it for 12 hours.[6] However, HURDAT maintains Emilia as a high-end Category 4 hurricane during this period.[1]
  6. ^ The status of Li between August 5 and August 8 is unclear. The Central Pacific Hurricane Center stated in their report on the tropical cyclones which occurred in their area of responsibility in 1994 that Li's organization became poor enough to merit discontinuation of advisories, entertaining the prospect that the system was a remnant low during this time;[6] however, HURDAT maintains Li as a tropical cyclone throughout its existence.[1]
  7. ^ Operationally, advisories were not initiated on Tropical Depression Eleven-E (future Hurricane Ileana) until 15:00 UTC on August 11, by which time it was already a tropical storm;[38] advisories were initiated on Tropical Depression Ten-E (future Hurricane John) six hours prior at 09:00 UTC,[39] resulting in that system receiving an earlier number despite forming 18 hours after Eleven-E.
