Pacific hurricane seasons 1992, 1993, 1994, 1995, 1996

The 1994 Pacific hurricane season officially started on May 15, 1994 in the eastern Pacific, and on June 1, 1994 in the central Pacific, and lasted until November 30, 1994. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone formed on June 18, while the last system dissipated on October 26.[1] This season, twenty-two tropical cyclones formed in the north Pacific Ocean east of the dateline, with all but two becoming tropical storms or hurricanes. This was the final season of the eastern north Pacific’s most recent active string of hurricane seasons. Of note in this season is an unusual spree of very intense storms. Hurricanes Emilia,

TD TS 1 2 3 4 5 This season, twenty-two tropical cyclones formed in the north Pacific Ocean east of the dateline. All but two of them became tropical storms or hurricanes. In the eastern Pacific (140°W to North America), nineteen tropical depressions formed, of which seventeen became tropical storms, nine became hurricanes, and five became major hurricanes of Category 3 intensity or higher on the Saffir Simpson Scale.[1] These numbers are the long-term averages of fifteen tropical storms, nine hurricanes, and four major hurricanes.[2] In the Central Pacific Hurricane Center’s area of responsibility (140°W to the International Date Line), three depressions, two tropical storms, and one hurricane formed. Over all, there were eleven tropical cyclones, eight tropical storms, five hurricanes, and three major hurricanes that formed or entered the central Pacific.[3] These numbers are well above the long-term average of four tropical cyclones, two hurricanes, one tropical storm, and two depressions.[4] The extremely high activity was contributed to by an El Niño ongoing at the time.[5] The only named storm to make landfall this year was Hurricane Rosa,[1] which killed several people in Mexico.[6] Other notable storms include Hurricane Olivia, which is one of the most intense Pacific hurricanes on record,[1] the three Category 5 hurricanes Emilia, Gilma, and John, and Hurricane Li, which existed in all three basins (East, Central, and West) of the Pacific Ocean.[7] This season is the swan song of the eastern north Pacific’s most recent active period.

That period, which began in 1982,[8] and includes the five most active Pacific hurricane seasons,[1] ended with this season.[8] Starting in 1995, multi-decadal factors switched to a phase that suppresses Pacific hurricane activity.[9] Since then, Pacific hurricane activity has been largely inactive.[10]

satellite images for days following the storm. The low finally dissipated north of Hawaii.[12] Aletta never affected land, and no damage or casualties were reported.[13] Tropical Depression One-E strengthened into Tropical Storm Aletta on June 19. That date is the fourth latest date for a season’s first tropical storm since 1966. It was the latest date since the 1968 season.[1]

Records
The 1994 Pacific hurricane season set several records. First, three hurricanes reached Category 5 intensity on the Saffir-Simpson Hurricane Scale.[7] The only other time that happened was in 2002. (The National Hurricane Center does not consider Emilia to have reached Category 5 intensity.) Two systems, Hurricanes Li and John, crossed through all three Pacific Ocean basins; this season is the only one to have more than one tropical cyclone do that.[1] Hurricane John was the longest lasting and most continuous tropical cyclone on Earth in recorded history.[11] Eleven tropical cyclones entered or formed in the central Pacific, a record shared with the 1992 season.[5] Finally, of the four most intense hurricanes on record in the central Pacific, three of them occurred this season.[3]

Tropical Storm Aletta
Tropical storm (SSHS)

Duration June 18 – June 23 Intensity 50 mph (85 km/h) (1-min), 999 mbar (hPa) Tropical Depression One-E formed from an area of disturbed weather on June 18. It strengthened to Tropical Storm Aletta the next day. It continued intensifying and reached its peak intensity on June 20. Vertical wind shear began to weaken the storm thereafter. The weakening trend continued, weakening Aletta to a depression on June 21. The system dissipated June 23. Aletta’s remnant low, however, could be tracked on

Duration June 27 – June 29 Intensity 45 mph (75 km/h) (1-min), 1003 mbar (hPa) Tropical Depression Two-E formed on June 27 about 575 miles (925 km) south-southwest of the tip of the Baja California Peninsula. The depression headed west-northwest, gradually turned to the northwest, and strengthened into Tropical Storm Bud on June 27. Early the next day, Bud peaked in intensity. Shear caused by a nearby upper level low slowly weakened Bud. Later on June 28, a second center of circulation developed. The two centers started a Fujiwhara interaction. The second center then became dominant and the first one vanished. This confused structure is similar to what happened to 1993’s Tropical Storm Arlene. This confused structure also weakened Bud to a tropical depression on the afternoon of the same day the second center formed. Bud then headed westward over cool waters and dissipated on June 29.[14] Tropical Storm Bud spent its entire life over the open ocean far from land areas. No casualties or damage was reported.[14]

south of South Point, Hawaii on July 15. That day, they caused rainfall on windward slopes of the Big Island locally reaching 5 inches (130 mm).[7] No reports of damage or casualties were received.[17]

Hurricane Emilia
Duration June 28 – July 5 Intensity 105 mph (165 km/h) (1-min), 967 mbar (hPa) The tropical depression that would be Carlotta formed on July 28. It quickly became Tropical Storm Carlotta, and a large eye became visible. Because of this, the NHC upgraded the storm to a hurricane. Carlotta peaked in intensity on July 1, as a 105 mph (169 km/h) hurricane. It gradually weakened as it moved into cooler waters, dissipating on July 5. Carlotta did not threaten land.[15] Carlotta buffeted Socorro Island with sustained winds of 39 miles per hour (63 km/h) on June 30.[15][16] Other than there, Carlotta caused no damage or deaths.[16] Category 5 hurricane (SSHS)

Tropical Storm Daniel
Tropical storm (SSHS)

Duration July 8 – July 14 Intensity 65 mph (100 km/h) (1-min), 993 mbar (hPa) On July 8, a disturbance located about 1,000 miles (1,600 km) southwest of the southern tip of the Baja California Peninsula developed a circulation and became Tropical Depression Four-E. Convection increased, and the depression strengthened into Tropical Storm Daniel. Upper-level outflow improved, and Daniel peaked in intensity on July 9. Daniel slowly declined as it continued westward. It entered the central Pacific on July 11. Wind shear weakened Daniel as it approached the Big Island, and by July 15 had degenerated into an open wave.[17] When Daniel was approaching Hawaii, moderate surf of 4 to 6 feet (1.2 to 1.8 m) impacted the south and southeast shores of the Big Island on July 13 and 14. Daniel’s remnants also passed about 100 miles (160 km)

Duration July 16 – July 25 Intensity 160 mph (260 km/h) (1-min), 926 mbar (hPa) On July 16, a area of low pressure associated with a tropical wave organized into Tropical Depression Five-E. It strengthened into Tropical Storm Emilia later that day. It moved west-northwest and strengthened into a hurricane.[18] It entered the central Pacific on July 17. It continued intensifying, reaching Category 5 intensity on July 19,[7] the first Category 5 Pacific hurricane since Ava. Emilia started weakening quickly on July 21. It weakened to a tropical storm on July 23 and dissipated two days later.[7] Emilia passed south of the Hawai’ian Islands, producing swells of 6 to 10 feet (1.8 to 3.0 m) in height near the Puna and Ka‘ū coasts. Winds caused minor damage, and rain was moderate.[7] No one was killed.[19]

Tropical Storm Fabio
Tropical storm (SSHS)

Duration July 19 – July 24 Intensity 45 mph (75 km/h) (1-min), 1002 mbar (hPa) A tropical depression formed on July 19. Later that day, it strengthened into Tropical

Storm Fabio. Fabio headed generally west or northwestward.[20] It entered the central Pacific as a tropical depression, and dissipated on July 24.[7] Fabio’s remnants brought locally heavy rainfall to Hawaii, reaching 3 to 4 inches (76 to 100 mm).[7] No one was killed and there was no damage.[21]

1994 Pacific hurricane season

Hurricane Gilma
Category 5 hurricane (SSHS) Duration July 31 – August 18 Intensity 75 mph (120 km/h) (1-min), ≤1007 mbar (hPa) A tropical disturbance southwest of Cabo San Lucas organized into Tropical Depression Eight-E on July 31.[24] It headed west-northwest without strengthening much, and crossed into the central Pacific on August 2.[25] Eight-E developed a second center of circulation, which became dominant,[26] and then became bound up in the intertropical convergence zone.[27] Eight-E then became disorganized, with multiple centers of circulation,[28] and advisories were discontinued on August 5. The depression’s remains continued their westward path well south of the Hawaiian Islands. The depression regenerated on August 8. It soon strengthened into a tropical storm and was named Li,[7] which is Hawaiian for "Lee".[29] Li approached the dateline on its generally westward heading. Just before crossing, it intensified into a minimal Category 1 hurricane. It crossed the dateline on August 12 and became a typhoon in the 1994 Pacific typhoon season.[7] Wind shear from a tropical upper-tropospheric trough weakened back into a tropical storm as it crossed the dateline, and the Joint Typhoon Warning Center downgraded Li with its first advisory.[30] Li stayed a tropical storm until August 16, where it weakened into a tropical depression. The system then began recurving, and dissipated on August 18.[31] A weakening Tropical Depression Li caused showers on Wake Island. Other than there, Li had no impact on any land, and no casualties or damage were reported.[7] Hurricane Li is one of only six tropical cyclones to exist on all three tropical cyclone basins in the Pacific Ocean. It is also one of only three systems to form as a depression in the east Pacific but be named in the central; the other two are Lala and Iniki.[1] However, the question of whether Li actually did those two things is somewhat complicated.

Duration July 21 – July 31 Intensity 160 mph (260 km/h) (1-min), 920 mbar (hPa) Part of a tropical wave organized into a tropical depression on July 21. It headed westward and out to sea, strengthening into a tropical storm the next day. Gilma rapidly strengthened and became a hurricane exactly one day after it was named. It continued to intensify as it entered the central Pacific. Shortly after entering the central Pacific, Gilma reached Category 5 intensity on the Saffir-Simpson Hurricane Scale, the second of the season.[22] It then suddenly weakened for unexplained reasons, and weakened into a tropical storm on July 27. It became a depression three days after that and dissipated on July 31.[7] Hurricane Gilma had minor impact on Johnston Atoll. That atoll received light rain, wind gusts to near gale force,[23] and surf.[7] No casualties or damage were reported.[23] Hurricane Gilma was the second most-intense Pacific at the time. As of 2008, it remains the sixth-most intense. Gilma is also the strongest July storm in the eastern or central Pacific.[1]

From Wikipedia, the free encyclopedia
Although the National Hurricane Center issued advisories on Tropical Depression EightE,[24] Li’s first data point in the official database has a longitude of 140°W, exactly on the boundary between the east and central Pacific.[1] However, in its preliminary report, the NHC includes a preliminary set of track data including several positions east of 140°W.[32] Hence, Li’s status as an east Pacific tropical cyclone is debatable.

1994 Pacific hurricane season

Tropical Storm Hector
Tropical storm (SSHS)

Duration August 7 – August 10 Intensity 65 mph (100 km/h) (1-min), 993 mbar (hPa) On August 7, a tropical depression formed from a tropical wave a few hundred miles south of Baja California. It became Tropical Storm Hector quickly, and as it paralleled the coast of Mexico, it began to weaken, dissipating on August 10. No damage was reported anywhere.[33] Tropical Storm Hector was forecast to approach the Baja California Peninsula. A tropical storm watch was issued for part of the peninsula on August 8. It was lifted later the same day.[34] Hector’s most significant impact was rain. The tropical storm dumped rain along a discontinuous zone of coastal and inland Mexico. The highest point maxima were 7.87 inches (200 mm) at Cerro de Ortega/Ixtlahua and 7.60 inches (193 mm) at Caduano/Santiago.[35] No damage or casualties were reported.[34]

August 9 – August 14 Duration 35 mph (55 km/h) (1-min) Intensity An area of disturbed weather organized into a tropical depression on August 9 while located 740 miles (1,190 km) southeast of Hilo, Hawaii. The depression moved westward without organizing, and dissipated on August 14.[7] Moisture from the system produced heavy rainfall over the island of Hawaii, totaling to over 15 inches (380 mm).[7] The flooding closed all major roads in Hilo, and was considered the worst flooding in 40 years. The rainfall destroyed 2 homes and damaged 214, 14 severely. It also damaged roads and businesses. Damage throughout the island totaled to $5 million (1993 USD).[36] Flooding occurred in Maui as well, where landslides blocked portions of the Hana Highway.[37] One-C’s point maximum of 15 in (380 mm) makes it Hawaii’s seventh wettest known tropical cyclone.

Hurricane Ileana
Category 1 hurricane (SSHS)

Tropical Depression One-C
Tropical depression (SSHS)

Duration August 10 – August 14 Intensity 75 mph (120 km/h) (1-min), 986 mbar (hPa) A disturbance that was part of the intertropical convergence zone developed several centers of circulation. After it organized, it separated from the ITCZ and became Tropical Depression Eleven-E on August 10 while the system was about 690 miles (1,110 km) south-southeast of the southern tip of the

Baja California Peninsula.[38] It was upgraded to Tropical Storm Ileana at the second advisory,[39] at the same time as John, the next storm.[40] An eye appeared, and Ileana became a hurricane on August 12. It began weakening almost immediately thereafter, as it passed over cooler waters and encountered increasing wind shear. Ileana was a tropical storm on August 13, and the next day it was a dissipating swirl low-level clouds located about 520 miles (840 km) west of Punta Eugenia.[38] Although Ileana paralleled the coast of Mexico, watches and warnings were not issued because winds of tropical storm-force were not expected to affect land. No one was killed and there was no damage reported in association with this cyclone.[38]

1994 Pacific hurricane season
Ahead of the hurricane, the 1100 people at Johnston Atoll evacuated. On the atoll, John caused $15 million (1994 USD) in damage. No deaths were reported. Other than on Johnston, Hurricane John had no impact on land.[7] Hurricane John was the longest lasting and farthest traveling tropical cyclone on Earth in recorded history.[11] It is also one of six tropical cyclones to exist in all three basins of the Pacific Ocean, an uncommon west-to-east dateline crosser, and one of the few tropical cyclone to cross the dateline more than once.[1]

Tropical Depression Twelve-E
Tropical depression (SSHS)

Hurricane John
Category 5 hurricane (SSHS)

Duration August 11 – September 10 Intensity 175 mph (280 km/h) (1-min), 929 mbar (hPa) Tropical Depression Ten-E formed on August 11 south of Mexico. It headed generally westward, and was upgraded into a tropical storm twelve hours after it formed and was named John. John fluctuated in strength as it headed west, always managing to stay at tropical storm strength. On August 20, steady intensification began, and John was a major hurricane when it entered the central Pacific. It continued westward, reaching Category 5 intensity on August 23. It passed around 245 miles (394 km) south of Hawaii, and passed just north of Johnston Atoll on August 26.[41] John stayed at hurricane intensity until it crossed the dateline on August 28, becoming a typhoon of the 1994 Pacific typhoon season.[7] After weakening into a tropical storm, John recurved, looped, and recurved again.[42] It reintensified, and was a hurricane when it recrossed the dateline to reenter the central Pacific. John headed north-northeast until it went extratropical on September 10,[7] thirty one days after it formed.[1]

Duration August 12 – August 15 Intensity 35 mph (55 km/h) (1-min), 1006 mbar (hPa) On August 14, an area of convection organized enough to be considered a tropical depression. It was steered by John’s circulation, and it was never expected to strengthen much because it was close to cool waters.[43] The cyclone drifted north, then northeast, north again, northwest, and then west.[44] The National Hurricane Center declared the depression dissipated on August 15.[45] The depression had no effects anywhere.[44]

Hurricane Kristy
Category 2 hurricane (SSHS)

Duration August 28 – September 5

From Wikipedia, the free encyclopedia
Intensity 105 mph (165 km/h) (1-min), ≤992 mbar (hPa) On August 28, Tropical Depression ThirteenE formed about 1,300 miles (2,100 km) southwest of Cabo San Lucas, Mexico. It was named Tropical Storm Kristy on August 30. As it crossed into the central Pacific, a banding-type eye formed and it became a hurricane.[46] Twelve hours later, it Category 2 intensity. Kristy weakened steadily from that point due to wind shear. It passed about 300 mi (480 km) south of Hawaii, and dissipated on September 5.[7] The lowest central pressure of Kristy is unknown. The last estimate was made when Kirsty was still a tropical storm.[1] As it approached the Hawaiian Islands, a high surf advisory and a high wind warnings were issued for the Big Island of Hawaii. No damage or deaths were reported in association with this system.[47]

Tropical Storm Mele
Tropical storm (SSHS)

Hurricane Lane
Category 4 hurricane (SSHS)

September 6 – September 9 Duration 40 mph (65 km/h) (1-min) Intensity A tropical disturbance became Tropical Depression Two-C on September 6. It reached tropical storm strength the next day, being named Mele.[7] The name Mele means "song" in the Hawaiian language and is also the Hawaiian form of "Mary".[49] Mele headed west-northwest and weakened back into a tropical depression on September. It dissipated later that day without incident.[7]

Tropical Storm Miriam
Tropical storm (SSHS)

Duration September 3 – September 10 Intensity 130 mph (215 km/h) (1-min), 948 mbar (hPa) The same tropical wave that spawned Tropical Depression Five in the Atlantic became Tropical Depression Fourteen-E on September 3. It quickly became Tropical Storm Lane. A high pressure ridge centered itself north of Lane, keeping the storm on a westward track. This brought Lane into very favorable conditions, and Lane intensified. When the tropical storm reached hurricane strength, it entered a phase of rapid intensification, reaching winds of about 135 mph (217 km/h), making it a category four hurricane. The high pressure ridge shifted eastward, and allowed Lane to enter unfavorable conditions. Lane dissipated on September 10.[48]

Duration September 15 – September 21 Intensity 45 mph (75 km/h) (1-min), 1002 mbar (hPa) Miriam formed from a weak disturbance on September 15. It strengthened slightly into Tropical Storm Miriam, and dissipated on September 21, having led an uneventful life without impact. In an interesting occurrence, the low-level remnants of Miriam were still visible for weeks after the storm dissipated near 140°W.[50]

Tropical Storm Norman

finished the loop, it had weakened to a tropical storm. It then headed westward. It weakened into a tropical depression on September 28 and dissipated the next day. No impact was reported.[53] When it formed, Hurricane Olivia was the third most-intense Pacific hurricane ever recorded, and second most-intense in the east Pacific proper. Since then, several other hurricanes have reached a lower pressure, but Olivia remains the ninth most-intense Pacific hurricane, seventh-most in the east Pacific proper. Olivia was also the strongest September hurricane at the time. It held that record until Hurricane Linda broke it. Olivia is still the third strongest September hurricane. Olivia is also the most intense Pacific hurricane not to reach Category 5 intensity. Hurricane Olivia shares its intensity records and rankings with 2001’s Juliette.[1]

Duration September 19 – September 22 Intensity 40 mph (65 km/h) (1-min), 1004 mbar (hPa) A tropical depression formed on September 19, and became Tropical Storm Norman the next day. After tracking northwest, it began to turn north in response to a trough, and convection began to diminish. Norman dissipated on September 22 without having ever affected land.[51]

Hurricane Olivia
Category 4 hurricane (SSHS)

Tropical Storm Paul
Tropical storm (SSHS)

Duration September 22 – September 29 Intensity 150 mph (240 km/h) (1-min), 923 mbar (hPa) Hurricane Olivia ultimately formed from a disturbance that had separated from the intertropical convergence zone and become distinct by September 19. The disturbance slowly headed westward and it organized into a tropical depression on September 22 while located about 720 miles (1,160 km) south of the southern tip of the Baja California Peninsula. The depression headed west-northwestwards and strengthened into Tropical Storm Olivia on September 22. It steadily intensified and was a hurricane on September 24. It then rapidly strengthened into a powerful major hurricane. It slowly curled to the northwest as it was observed by NOAA research aircraft.[52] Olivia peaked in intensity on September 25. Meanwhile, a large cyclone off the extreme southern part of California induced a northward path. As Olivia started a small anticyclonic loop, wind shear began to weaken the hurricane. When Olivia was

Duration September 24 – September 30 Intensity 45 mph (75 km/h) (1-min), 1003 mbar (hPa) A nearly stationary cluster of thunderstorms and convection that had been hanging around since September 15 and escaped destruction by Tropical Storm Miriam organized into Tropical Depression Eighteen-E on September 24. It was located between Miriam’s remnants and the developing Olivia. It became Tropical Storm Paul on the afternoon of September 25. It peaked in intensity on September 27. Then, upper outflow from the nearby Olivia started shearing the tropical cyclone. Paul had been completely destroyed by September 30.[54] The tropical cyclone never threatened land, and consequently, no damage or deaths were reported.[55]

Hurricane Rosa

caused 700 million USD (year unknown) in damage.[60]

Tropical Storm Nona
Tropical storm (SSHS)

Duration October 8 – October 15 Intensity 105 mph (165 km/h) (1-min), 974 mbar (hPa) An area of disturbed weather organized into a tropical depression at midday on October 8. It had trouble organizing, and advisories were discontinued for a while. The cyclone finally became a tropical storm on October 11 and was named Rosa. It moved glacially, but eventually a trough steered Rosa north and then northeast. Rosa intensified quickly, peaking at Category 2 intensity just before landfall near La Concepcion on the morning of October 14. Rosa quickly decayed over the mountains of Mexico, and its cloud shield rapidly accelerated northward through the United States, spreading moisture.[56] On October 12, a hurricane watch was issued for the coast from Culiacan to Manzanillo and the Baja California Peninsula south of latitude 24°N. At the same time, a tropical storm warning was issued from Manzanillo to Tepic. On October 14, a hurricane warning was issued for the coast between Culiacan and Cabo Corrientes, and a tropical storm warning south of Cabo Corrientes to Manzanillo. All watches and warnings were lifted later that day.[57] Four deaths, two in each of Nayarit and Durango, were reported. Four people were missing in Sinaloa. All of the deaths were due to drowning. More than 100,000 people had their homes damaged in Nayarit. Telephone poles and power lines were downed in Sinaloa. Rain caused landslides and flash-flooding in mountainous areas.[6] In Jalisco, mudslides forced the evacuation of 400 people from two coastal villages.[58] The highest rainfall total in Mexico was 14.09 inches (358 mm) at Mesa de Pedro Pablo.[59] The moisture Rosa sent into the United States was a contributing factor in record rains in parts of southeastern Texas from October 15 to 19. Those rains caused flooding that killed 22 people, destroyed over 3000 homes, and

October 21 – October 26 Duration 40 mph (65 km/h) (1-min) Intensity Tropical Depression Three-C formed on October 21 in the Central Pacific basin. It traveled westward for about 4 days before strengthening to Tropical Storm Nona on October 25.[7] The name "Nona" is Hawaiian for the Latin name spelled the same way.[61][62] Nona immediately weakened back into a tropical depression. Upper-level westerlies from a nearby trough destroyed the depression on October 26. No deaths or damage were reported.[7] Nona was a tropical storm for six hours,[1] the minimum possible time.[63]

It defines 2 Emilia 1.72 12 Hector 1.65 below-normal as having an ACE less than (31.4) 95*104 kt2 kt2; It defines above normal as 3 Gilma 5.80 13 Aletta 1.42 having an ACE above 150*104 kt2 along with (18.8) the numbers of any two of the following above average: tropical storms (15), hur4 Olivia 16.5 14 Miriam 1.30 ricanes (9), or major hurricanes (4); It 5 Lane 12.7 15 Paul 1.22 defines near-normal as having an ACE 6 Carlotta 10.5 16 Mele (0.980) between 100*104 kt2 and 150*104 kt2, or an ACE above 150*104 kt2 with fewer than two 7 Rosa 6.21 17 Fabio 0.65 of the numbers of the following above aver8 Kristy 1.02 18 Norman 0.613 age: tropical storms (15), hurricanes (9), or (5.16) major hurricanes (4).[2] This season has a total of seventeen trop9 Daniel 2.91 19 Bud 0.565 ical storms, nine hurricanes, and five major (2.22) hurricanes. The total ACE of this season is 10 Li (4.48) 20 Nona (0.123) 185*104 kt2. This qualifies this season as Total: 78.0 (107) above-normal.[2]

Accumulated Cyclone Energy (ACE) is a measure of how active a hurricane season is. It is calculated by squaring the windspeed of a cyclone with at least tropical storm-force winds every six hours, summing the results, and dividing that total by 104. As a tropical cyclone does not have gale-force winds until it becomes a tropical storm, tropical depressions are not included in these tables. For all storms, ACE is given to three significant figures. The ACE in the east Pacific proper (140°W to North America) is given; the ACE

Storm names
The following names were used for named storms that formed in the eastern Pacific in 1994; names that were not assigned are marked in gray. No names were retired, so it was used again in the 2000 season. This is the same list used for the 1988 season except for Ileana, which replaced Iva. A storm was named Ileana for the first time in 1994. • Aletta • Ileana • Rosa
