1999 North Indian Ocean cyclone season
The 1999 Pacific hurricane season was one of the least active Pacific hurricane seasons on record. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; in both basins, it ended on November 30. These dates conventionally delimit the period during which most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone of the season, Hurricane Adrian, developed on June 18, while the final storm of the season, Tropical Storm Irwin, dissipated on October 11. No storms developed in the Central Pacific during the season. However, two storms from the Eastern Pacific, Dora and Eugene, entered the basin, with the former entering as a hurricane and becoming the second farthest travelling Pacific hurricane on record.
The season produced fourteen tropical cyclones and nine named storms, which was well below the average of sixteen named storms per season; this was largely due to a strong La Niña taking over much of the Pacific. However, the total of six hurricanes and two major hurricanes during the season was near the averages of eight and three, respectively. Although it remained offshore, Hurricane Adrian caused 6 deaths from flooding and rough surf in Mexico. The deadliest tropical cyclone, Hurricane Greg, killed 10 people from flooding in Mexico.
Seasonal summary
Timeline of the 1999 Pacific hurricane season
The 1999 Pacific hurricane season officially started on May 15, 1999 in the eastern Pacific, and on June 1, 1999, in the central Pacific, and lasted until November 30, 1999. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.http://www.prh.noaa.gov/cphc/pages/FAQ/#4 4. When is hurricane season? April 13, 2012 Central Pacific Hurricane Center March 2, 2013 April 6, 2010 https://web.archive.org/web/20100406104153/http://www.prh.noaa.gov/cphc/pages/FAQ/#4 live The 1999 Pacific hurricane season was well below average, due to the strong La Niña that was occurring at the time, which causes wind shear to be increased and water temperatures to decrease, resulting in conditions less conductive for tropical cyclones in the East Pacific. There were 14 cyclones in total, including 5 unnamed tropical depressions. Of these, 9 became a tropical storm, while 6 reached hurricane status. Further, 2 of these became major hurricanes, which is Category 3 intensity or higher on the Saffir-Simpson hurricane scale.Eastern North Pacific Hurricane Season of 1999 John L. Beven II James L.

Tropical cyclogenesis began with Hurricane Adrian, which developed on June 18. Although it remained offshore, Adrian brought rough surf and flooding to Mexico, which resulted in 6 fatalities. The storm peaked as a Category 2 before dissipating on June 22. No other tropical cyclones formed in June. Activity halted until July 9, when Hurricane Beatriz developed. Though it peaked as a Category 3 hurricane before dissipating on July 17, the storm caused no damage on land because it remained well offshore. The next system, a short-lived Tropical Depression Three-E, did not result in impact as a tropical cyclone, though the precursor brought heavy rainfall and gusty winds to Central America. Tropical Depression Four-E, was the first of three cyclones to cross into the Central Pacific Hurricane Center's area of responsibility, which is between 140°W and the International Date Line. Two other short-lived system in July, Tropical Storm Calvin and Tropical Depression Six-E, caused no damage.
In August, Hurricane Dora, the strongest storm of the 1999 Pacific hurricane season, produced gusty winds and large waves on Johnston Atoll and the island of Hawaii, though minimal damage was left in its wake. After crossing the International Date Line on August 20, Dora became the first tropical cyclones to exist in all three basins of the North Pacific – Eastern, Central, and Western – since Hurricane John in 1994. Hurricane Eugene also existed in the Eastern and Central Pacific, but dissipated on August 15 while south of the main Hawaiian Islands, well before reaching the International Date Line. Nonetheless, it produced up to 2 in mm of rainfall on the Big Island of Hawaii. In the remainder of August, there was a series of short-lived tropical cyclones that did not effect land, including Tropical Depression Nine-E, Tropical Storm Fernanda, and Tropical Depression Eleven-E.
During the month of September, the deadliest tropical cyclone of the season, Hurricane Greg, was spawned near the Pacific coast of Mexico. Greg which killed 10 people when it made landfall on southern Baja California. The hurricane and its precursor produced heavy rainfall across much of Mexico, with the highest total reaching 22.23 in mm on. The heavy rains damaged or destroyed more than 2,000 homes. The remnant moisture from the system, combined with an area of low pressure, resulted in strong thunderstorms across California, which led to numerous power outages, damage to homes and vehicles, and started many wildfires. The other in the month of September was Hurricane Hilary, a storm that approached Baja California, but dissipated offshore on September 21, resulting in no impact. The final system, Tropical Storm Irwin, produced scattered areas of heavy rainfall over Mexico in October, but caused no significant flooding. It dissipated on October 11, over a month and a half before the official end of the season on November 30.
In addition to the systems observed by the CPHC and NHC, a tropical depression formed east of the International Dateline on August 19, and quickly exited CPHC's area of responsibility;Japan Meteorological Agency 2015 November 29, 2015 Japan Meteorological Agency Best Tracks http://www.jma.go.jp/jma/jma-eng/jma-center/rsmc-hp-pub-eg/Besttracks/bst_all.zip ZIP December 8, 2015 https://web.archive.org/web/20151208052939/http://www.jma.go.jp/jma/jma-eng/jma-center/rsmc-hp-pub-eg/Besttracks/bst_all.zip liveJoint Typhoon Warning Center 1998 November 29, 2015 bwp061998 http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/1998/1998s-bwp/bwp061998.txt TXT December 8, 2015 https://web.archive.org/web/20151208115721/http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/1998/1998s-bwp/bwp061998.txt dead however, this storm was not included into CPHC database.

In mid-June, a broad cyclonic area of cloudiness persisted to the south of the Gulf of Tehuantepec. A low-level circulation and banding features became more prominent on June 16, and further development was aided by the presence of a tropical wave that first departed the western coastline of Africa on June 5. As extremely deep convection festered within a band west of the disturbance's center, it is estimated the first tropical depression of the season formed around 06:00 UTC on June 18, located about 260 mi (420 km) southeast of Acapulco, Mexico. The newly-formed cyclone tracked west-northwest parallel to the coastline, steered by a strong area of high pressure to its north and east.http://www.nhc.noaa.gov/1999adrian.html Preliminary Report: Hurricane Adrian Miles B.

A tropical wave developed into by 0600 UTC on July 9, while situated roughly 300 mi km on south of Lázaro Cárdenas, Mexico. At this time, the depression was in an environment of strong upper-tropospheric outflow, resulting in gradual intensification. The depression was upgraded to Tropical Storm Beatriz at 1200 UTC on July 9. Steady strengthened continued and about 48 hours later, Beatriz became a Category 1 while situated roughly 560 mi km south-southwest of Cabo San Lucas. Moving westward around the southern periphery of a ridge to the north, it continued to intensify. A well-defined eye became visible on satellite imagery early on July 12. Microwave imagery a few hours later revealed that Beatriz was likely undergoing an eyewall replacement cycle and was complete by 1700 UTC.http://www.nhc.noaa.gov/1999beatriz.html Preliminary Report: Hurricane Beatriz Richard J.

Further intensification occurred, and Beatriz became the first major hurricane of the season at 1800 UTC on July 12. At 0600 UTC the following day, the hurricane attained its peak intensity with winds of 115 mph km/h on and a minimum barometric pressure of 955 mbar inHg on while situated roughly 800 mi km southwest of Cabo San Lucas. Curving towards the west-northwest, Beatriz began to encounter an area of cooler sea surface temperatures, which led to gradual weakening. The hurricane weakened to a tropical storm at 0000 UTC on July 16, and further to a tropical depression by 1800 UTC that day. At 0600 UTC on July 17, Beatriz degenerated into a swirl of clouds.

The system organized further and developed into Tropical Depression Three-E at 1200 UTC on July 14, while located about 290 mi km west-southwest of Manzanillo, Mexico. It initially headed west-northwestward until July 15, when it curved west-southwestward. The depression failed to strengthen further and dissipated at 1800 UTC on July 15, while located about 460 mi km southwest of Cabo San Lucas, Mexico.

On July 15, a tropical wave entered the eastern Pacific Ocean. Over the following days, slow organization occurred, and it is estimated that the system became developed into Tropical Depression Four-E at 0000 UTC on July 23. Later that day, the depression reached its peak intensity with maximum sustained winds of 35 mph km/h on and a minimum barometric pressure of 1007 mbar inHg on, having failed to reach tropical storm status. While moving westward, the depression entered the Central Pacific Hurricane Center's area of responsibility on July 24.http://www.nhc.noaa.gov/1999four-e.html Brief Information About Tropical Depression Four-E Jack Beven August 3, 1999 National Hurricane Center March 1, 2013 October 15, 2012 https://web.archive.org/web/20121015181817/http://www.nhc.noaa.gov/1999four-e.html live By this time, however, the depression was already becoming disorganized and dissipated early on the following day.

A tropical wave crossed the Atlantic Ocean and Caribbean Sea between early and mid-July. Later in the month, the wave acquired a low-level circulation. Thus, Tropical Depression Five-E developed at 0600 UTC on July 25, while situated about 645 mi km south-southwest of Cabo San Lucas. Due to further organization on satellite imagery, the depression was upgraded to Tropical Storm Calvin six hours later. However, wind shear exposed the low-level circulation and halted intensification. Calvin continued west-northwestward as a sheared cyclone.http://www.nhc.noaa.gov/1999calvin.html Preliminary Report: Tropical Storm Calvin James L.

According to satellite classifications, it is estimated that Calvin weakened back to a tropical depression at 0600 UTC on July 26. There was a convective burst late on July 26, though the storm did not re-strengthen. Around that time, Calvin turned northwestward in response to a mid-tropospheric trough. The burst in convection did not persist and the depression dissipated by 1200 UTC on July 27, while located well west-southwest of Baja California. A low-cloud swirl remained and subsequently continued on a west-northwesterly course for a few days.

A tropical wave that previously crossed the Atlantic Ocean and Caribbean Sea reached the eastern Pacific basin until late July. The system developed a surface circulation on July 26, while microwave imagery data indicated wind speeds of 37 mph km/h on. As a result, it is estimated that Tropical Depression Six-E developed at 1800 UTC, while located nearly 1150 mi km west-southwest of the southern tip of Baja California and about 415 mi km southwest of Tropical Depression Calvin. The depression moved toward the west-northwest and encountered strong vertical wind-shear. Despite a few convective bursts, the depression remained weak and degenerated into a swirl of low clouds at 0000 UTC on July 28.http://www.nhc.noaa.gov/1999six-e.html Brief Information About Tropical Depression Six-E Lixion A.

Hurricane Dora (1999)
A tropical wave moved off Africa on July 23 and crossed the Atlantic Ocean without development. However, the wave quickly increased in organization after entering the Eastern Pacific Ocean on August 4, and was designated Tropical Depression Seven-E on August 6. The depression strengthened into Tropical Storm Dora later that day. Dora continued to intensify despite upper-level wind shear, and became a hurricane on August 8. Shortly after, the hurricane moved westward into a more favorable environment and began to intensify more quickly, reaching Category 4 strength on August 10. It maintained that intensity for three days as it moved almost due west.http://www.nhc.noaa.gov/1999dora.html Preliminary Report: Hurricane Dora Miles B. Lawrence Todd B.

Dora weakened to Category 1 strength as it entered the Central Pacific Hurricane Center's area of responsibility on August 14. However, it briefly restrengthened into a Category 3 as it passed south of Hawaii on August 16. Dora then began weakening for the final time as it passed south of Johnston Atoll on August 18. At the atoll, Dora produced large waves and wind gusts between 40 and 45 mph km/h on. In Hawaii, heavy surf on the Big Island forced the closure of beaches, campsites, and hiking trails in the districts of Kau and Puna.http://www1.ncdc.noaa.gov/pub/orders/IPS-F7FF2259-ADC1-4122-AEA9-56DD7FDE3477.pdf Storm Data and Unusual Weather Phenomena With Late Reports and Corrections: August 1999 Stephen Del Greco National Climatic Data Center 52 March 1, 2013November 2018 InternetArchiveBot yes On August 20, Dora crossed the International Date Line,http://www.prh.noaa.gov/cphc/summaries/1999.php The 1999 Central Pacific Hurricane Season Benjamin C.

Twelve hours later, the depression was upgraded to Tropical Storm Eugene. It continued to deepen, reaching hurricane status late on August 8. About 24 hours later, Eugene peaked as a strong Category 2 hurricane with winds of 110 mph km/h on. The storm began to weaken and was downgraded to a Category 1 hurricane early on August 11.http://www.nhc.noaa.gov/1999eugene.html Preliminary Report: Hurricane Eugene Richard J.

Eugene continued westward, and on August 11, it entered the Central Pacific Hurricane Center's area of responsibility. It continued to weaken and was downgraded to a tropical storm early on August 13. Eugene passed south of the Hawaiian Islands on August 14, with minimal impact noted. Minor surf occurred along the east and southeast shores of the Big Island. Additionally, 24‑hour rainfall totals over windward sections of Maui and the Big Island were near 2 in mm. The storm weakened to a tropical depression by late on August 14. At 0000 UTC on August 16, Eugene dissipated while located about 550 mi km southeast of Johnston Atoll.

A tropical wave developed into Tropical Depression Ten-E at 0600 UTC on August 17, while located about 460 mi km in south-southwest of Socorro Island, Mexico. The depression intensified gradually due to favorable conditions. At 0000 UTC on August 18, the cyclone was upgraded to Tropical Storm Fernanda while centered about 520 mi km southwest of Socorro Island. The storm continued to slowly strengthened and 1200 UTC on August 19, Fernanda attained its peak intensity with maximum sustained winds of 65 mph km/h on and a minimum barometric pressure of 994 mbar inHg on.http://www.nhc.noaa.gov/1999fernanda.html Preliminary Report: Tropical Storm Fernanda Jack Beven November 5, 1999 National Hurricane Center March 1, 2013 October 15, 2012 https://web.archive.org/web/20121015143740/http://www.nhc.noaa.gov/1999fernanda.html live
Around the time of peak intensity on August 19, Fernanda curved west-southwest track, a motion which persisted for the remainder of its duration. While this track carried the storm over warmer SST's, increasing easterly wind shear caused Fernanda to weaken. By early on August 21, Fernanda weakened to a tropical depression. After weakening slightly further, the storm degenerated into a remnant low cloud swirl at 0000 UTC on August 23. The remnants of Fernanda persisted until finally losing its identity about 290 mi km west-southwest of Socorro Island on August 28.

Thereafter, the system emerged into the Pacific Ocean and began to organize. By 1200 UTC on September 5, Tropical Depression Twelve-E developed near Manzanillo, Mexico. Six hours later, the depression strengthened into Tropical Storm Greg. Further intensification occurred, and late on September 6, Greg was upgraded to a hurricane as winds reached 75 mph km/h on. However, Greg weakened to a tropical storm on September 7, while approaching Baja California. At 2100 UTC that day, it made landfall near Cabo San Lucas. The storm then curved westward and weakened over colder SST's, until dissipating on late September 9.http://www.nhc.noaa.gov/1999greg.html Preliminary Report: Hurricane Greg Lixion A.

A tropical wave moved off the coast of western Africa into the Atlantic Ocean on August 29. It continued to move westward through the tropical waters of the Atlantic into the Caribbean. It still remained a tropical wave as it moved over Central America and began to acquire more convection and organization, from September 10 through September 11. Visible satellite imagery showed low level circulation and more organized deep convection as it became a tropical depression on September 17, while located about 475 mi km south-southeast of the southern tip of the Baja California Peninsula.
The system strengthened and was upgraded to Tropical Storm Hilary at 1200 UTC on September 18. Due to the development of an eye feature and large increase in deep convection, Hilary was upgraded to hurricane on September 20, while located about 200 mi km southwest of the Baja California Peninsula. However, later that day, Hilary weakened back to a tropical storm. The storm fell further to tropical depression status on September 21. Hours later, the storm degenerated into a swirl of low-level clouds, as it bypassed Baja California on September 21.http://www.nhc.noaa.gov/1999hilary.html Preliminary Report: Hurricane Hilary Miles B.

The southern portion of the tropical wave that previously spawned Tropical Depression Eleven in the Gulf of Mexico entered the Pacific Ocean in early October. After becoming better organized, the system developed into Tropical Depression Fourteen-E at 1200 UTC on October 8, while situated about 145 mi km south-southwest of Manzanillo, Mexico. The depression initially moved slowly north-northwestward and strengthened into Tropical Storm Irwin about six hours later. After a strong mid-tropospheric ridge developed over northern Mexico, Irwin moved northwestward and remained offshore Mexico.http://www.wpc.ncep.noaa.gov/tropical/rain/irwin1999.html Preliminary Report: Tropical Storm Irwin Richard J.

Early on October 9, the center of the storm passed within about 85 mi km of the coastline between Manzanillo and Cabo Corrientes. The storm then curved west-northwestward and at 1800 UTC on October 9, Irwin attained peaked with winds of 60 mph km/h on. Stable air and increasing wind shear caused Irwin to weaken and fall to tropical depression intensity early on October 11. About 12 hours later, the storm dissipated while located about 405 mi km southwest of Cabo San Lucas. While passing offshore, Irwin brought patches of heavy rainfall to some areas of Mexico, peaking at 9.92 in mm in Coahuayutla de Guerrero, Guerrero.http://www.wpc.ncep.noaa.gov/tropical/rain/irwin1999.html Tropical Storm Irwin - October 7-10, 1999 David M.

For storms that form in the North Pacific between 140°W to the International Date Line, the names come from a series of four rotating lists. Names are used one after the other without regard to year, and when the bottom of one list is reached, the next named storm receives the name at the top of the next list. No named storms formed within the area in 1999. Named storms in the table above that crossed into the area during the season are noted (*).Tropical Cyclones 1999 Benjamin Hablutzel James Weyman Hans Rosendal Paul Jendrowski Jonathan Hoag Raymond Tanabe July 2000 https://www.nhc.noaa.gov/data/tcr/CP1999_Seasonal_TCR.pdf Central Pacific Hurricane Center Honolulu, Hawaii January 31, 2024
Season effects
This is a table of all of the tropical cyclones that formed in the 1999 Pacific hurricane season. It includes their name, duration (within the basin), peak classification and intensities, areas affected, damage, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 1999 USD.
