According to ship reports during the summer, the Intertropical Convergence Zone was farther north than usual, which created favorable conditions for tropical cyclogenesis. [2] According to weather charts at the Honolulu International Airport, a tropical depression developed at 00:00  UTC on August 12, while located about 760 miles (1,220 km) southeast of the Big Island. [3] [4] Thereafter, the storm gradually intensified, becoming a tropical storm at 06:00 UTC on August 13. It was named Hiki, which is Hawaiian for Able. While situated east of Hilo, Hawaii, the system was described as an "immature storm", and had a very small diameter. Shortly thereafter, a reconnaissance aircraft flew into Hiki and estimated that sustained wind speeds between 50 and 60 mph (80 and 100 km/h). Further intensification continued and the system strengthened into a hurricane on August 16. [4] Upon reaching hurricane intensity on August 16, Hiki simultaneously attained its maximum sustained wind speed of 85 mph (140 km/h). [3] Despite this, the storm had remained small, with gale force winds extending less than 150 mi (240 km) from the center. Hiki remained between 100 and 200 mi (160 and 320 km) offshore while paralleling several Hawaiian Islands, including Hawaii, Maui, Molokai, Oahu, and Kauai. [4]

As a high pressure ridge intensified, the northwestward movement of Hiki was blocked, causing the storm to briefly turn due west on August 17. The high pressure ridge eventually influenced the hurricane to re-curve southwestward. On August 18, a reconnaissance aircraft observed sustained winds of 90 mph (150 km/h) to the south of the center; a minimum barometric pressure of 982  mbar (29.0  inHg ) was also observed. After the reconnaissance aircraft flight into the storm on August 18, residents of Kauai and Oahu were alerted of a possible cyclonic loop. However, later that day, the high pressure ridge weakened, causing Hiki to turned westward and pass south of French Frigate Shoals and Midway Island. [4] Late on August 19, Hiki weakened to a tropical storm and then resumed its course to the northwest. By August 21, Hiki further weakened to a tropical depression, and dissipated six hours later. [3]

The hurricane was also followed by the Air Weather Service, located on Guam, who assigned the name Salome from the Pacific typhoon naming lists. [5]

Hiki was one of the strongest tropical cyclones to approach the Hawaiian Islands in at least 45 years and officially the first hurricane in the region. [2] As Hiki approached, a United States Coast Guard station with 14 people in French Frigate Shoals was alerted. In addition, ships in the area were also advised to take caution. Hiki caused high waves on some of the Hawaiian Islands. [14] Hawaii remained on the southern semicircle of Hiki, and as a result, light wind damage occurred. The highest reported winds from Hiki was at the Kilauea Lighthouse on Kauai, where gusts up to 68 mph (109 km/h) were observed. The islands of Niihau and Lanai also experienced tropical storm force winds, reaching 48 and 50 mph (77 and 80 km/h), respectively. As a result, several houses throughout the Hawaiian Islands lost their roof. In addition, a farmer in Kohala on Hawaii died after coming into contact with a live wire that was blown down from high winds. [4]

Hiki was the wettest tropical cyclone in United States history, as rainfall of over 52 in (1,300 mm) observed at the Kanalohuluhulu Ranger Station on Kauai between August 14 and August 18. [4] [1] The rain gauge was capable of holding 24 inches (610 mm) of the rain and was emptied on August 15. However, less than 24 hours later, the same rain gauge was overflowing. Heavy precipitation was also recorded on other locations on that island, including 13 inches (330 mm) on Mount Waialeale. Few reports exist on rainfall totals on other Hawaiian Islands, with the only other island recording rainfall was Maui, with precipitation reaching 11.9 inches (300 mm) on August 15. This was the highest 24‑hour record for that island in the month of August. [4] On Kauai, the Waimea River experienced one of the worst flood in its history, causing more than 200 residents in Waimea Valley to evacuate. The river also rose near the mouth of its tributary, the Makaweli River, flooding the town of Waimea, causing about $200,000 in damage. [15] The streets on the island and hundreds of acres of sugar cane were flooded. Additionally, severe damage was reported at the Kekaha Powerhouse. [4]

<span class="mw-page-title-main">1960 Atlantic hurricane season</span> Hurricane season in the Atlantic Ocean

The 1960 Atlantic hurricane season was the least active season since 1952. The season officially began on June 15, and lasted until November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first system, an unnamed storm, developed in the Bay of Campeche on June 22. It brought severe local flooding to southeastern Texas and was considered the worst disaster in some towns since a Hurricane in 1945. The unnamed storm moved across the United States for almost a week before dissipating on June 29. In July, Hurricane Abby resulted in minor damage in the Leeward Islands, before impacting a few Central American counties — the remnants of the storm would go on to form Hurricane Celeste in the East Pacific. Later that month, Tropical Storm Brenda caused flooding across much of the East Coast of the United States. The next storm, Hurricane Cleo, caused no known impact, despite its close proximity to land.

<span class="mw-page-title-main">Hurricane Iniki</span> Category 4 Pacific hurricane in 1992

Hurricane Iniki was the most powerful hurricane to strike Hawaiʻi in recorded history. Forming on September 5, 1992, during the strong 1990–1995 El Niño, Iniki was one of eleven Central Pacific tropical cyclones during that season. It attained tropical storm status on September 8 and further intensified into a hurricane the next day. After turning north, Iniki struck the island of Kauaʻi on September 11 at peak intensity; it had winds of 145 mph and reached Category 4 status on the Saffir–Simpson hurricane scale. It had recorded wind gusts of 225 mph (362 km/h) as evidenced by an anemometer that was found blown into the forest during clean up. It was the first hurricane to hit the state since Hurricane Iwa in the 1982 season, and is the only known major hurricane to hit the state. Iniki dissipated on September 13 about halfway between Hawaii and Alaska.

<span class="mw-page-title-main">Hurricane Iwa</span> Category 1 Pacific hurricane in 1982

Hurricane Iwa, taken from the Hawaiian language name for the frigatebird, was at the time the costliest hurricane to affect the state of Hawaiʻi. Iwa was the twenty-third tropical storm and the twelfth and final hurricane of the 1982 Pacific hurricane season. It developed from an active trough of low pressure near the equator on November 19. The storm moved erratically northward until becoming a hurricane on November 23 when it began accelerating to the northeast in response to strong upper-level flow from the north. Iwa passed within 25 miles of the island of Kauaʻi with peak winds of 90 mph (140 km/h) on November 23, and the next day it became extratropical to the northeast of the state.

<span class="mw-page-title-main">2003 Pacific hurricane season</span> Hurricane season in the Pacific Ocean

The 2003 Pacific hurricane season was the first season to feature no major hurricanes – storms of Category 3 intensity or higher on the Saffir–Simpson hurricane wind scale (SSHWS) – since 1977. The dates conventionally delimiting the period when most tropical cyclones form in the Pacific Ocean are May 15 in the Eastern Pacific Ocean and June 1 in the Central Pacific, with both seasons ending on November 30. The 2003 season featured 16 tropical storms between May 19 and October 26; 7 of these became hurricanes, which was then considered an average season. Damage across the basin reached US$129 million, and 23 people were killed by the storms.

<span class="mw-page-title-main">1992 Pacific hurricane season</span> Hurricane season in the Pacific Ocean

The 1992 Pacific hurricane season is the most active Pacific hurricane season on record, featuring 27 named storms, and the second-costliest Pacific hurricane season in history, behind the 2013 season. The season also produced the second-highest ACE value on record in the basin, only surpassed by the 2018 season. The season officially started on May 15 in the eastern Pacific, and on June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. However, these bounds were easily exceeded when Hurricane Ekeka formed on January 28 and again a couple months later with Tropical Storm Hali.

<span class="mw-page-title-main">Hurricane Dot (1959)</span> Category 4 Pacific hurricane in 1959

Hurricane Dot of August 1959 was at its time the costliest tropical cyclone in Hawaiian history. Dot was first identified as a strong tropical storm southeast of Hawaiʻi on August 1. The storm was potentially a continuation of a previously unnamed tropical cyclone that was monitored west of the Baja California Peninsula from July 24–27, but was never confirmed due to a lack of ship reports. Dot was quick to intensify, reaching hurricane intensity six hours after naming. By August 3, Dot reached its peak intensity, with maximum sustained winds reaching 150 mph (240 km/h). Intensity leveled off afterwards as Dot tracked westward before making a curve towards the northwest on August 5, after which the hurricane weakened at a faster clip. Dot made landfall the next day on Kauai as a minimal hurricane before dissipating west of the Hawaiian Islands on August 8.

Hurricane Nina was the final tropical storm and hurricane of the 1957 Pacific hurricane season and the last storm to form during the active Central Pacific hurricane season this year. This storm was named "Nina" because during this time, hurricanes in this basin were given names from the typhoon naming lists. This storm was the last to form during a series of typhoons to form in the Pacific in November.

<span class="mw-page-title-main">Hurricane Felicia (2009)</span> Category 4 Pacific hurricane in 2009

Hurricane Felicia was the third strongest tropical cyclone of the 2009 Pacific hurricane season, as well as the strongest storm to exist in the eastern Pacific at the time since Hurricane Daniel in 2006. Forming as a tropical depression on August 3, the storm supported strong thunderstorm activity and quickly organized. It became a tropical storm over the following day, and subsequently underwent rapid deepening to attain hurricane status. Later that afternoon, Felicia developed a well-defined eye as its winds sharply rose to major hurricane-force on the Saffir–Simpson scale. Further strengthening ensued, and Felicia peaked in intensity as a Category 4 hurricane with sustained winds of 145 mph (233 km/h) and a barometric pressure of 935 mbar. After reaching this strength, unfavorable conditions, such as wind shear, began to impact the storm while it took on a northwestward path. Henceforth, Felicia slowly weakened for several days; by August 8 it had been downgraded to a Category 1 hurricane, once again becoming a tropical storm the next day. It retraced westward towards Hawaii on August 10, all the while decreasing in organization. On August 11, Felicia weakened to tropical depression status, and soon degenerated into remnant low just prior to passing over the islands.

<span class="mw-page-title-main">2013 Pacific hurricane season</span> Hurricane season in the Pacific Ocean

The 2013 Pacific hurricane season was the first to see twenty named storms since 2009 but also had the ninth fewest ACE units on record, as many of the storms were weak and short-lived. The season officially began on May 15 in the Eastern Pacific and started on June 1 in the Central Pacific. Both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the eastern Pacific basin. However, the formation of a storm is possible at any time.

<span class="mw-page-title-main">2014 Pacific hurricane season</span> Hurricane season in the Pacific Ocean

The 2014 Pacific hurricane season was the fifth-busiest season since reliable records began in 1949, alongside the 2016 season. The 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.

<span class="mw-page-title-main">1950 Pacific hurricane season</span> Hurricane season in the Pacific Ocean

The 1950 Pacific hurricane season was notable for one of the storms being the third-wettest tropical cyclone in United States history. Seven known tropical cyclones occurred during the season, the earliest of which formed on June 14 and the latest of which dissipated on October 3. These dates fall within the range of most Eastern Pacific tropical cyclone activity.

<span class="mw-page-title-main">Hurricane Gil (1983)</span> 1983 Pacific hurricane that affected Hawaii

Hurricane Gil was the first of several tropical cyclones to affect Hawaii during the 1983 Pacific hurricane season. The seventh named storm and third hurricane of the annual season, Gil originated from a tropical depression that developed near Clipperton Island on July 23. Steadily intensifying, it attained tropical storm status six hours later and was upgraded to a hurricane on July 26. After attaining peak intensity on July 27, Gil encountered cooler sea surface temperatures and began to weaken. Moving west-northwest, the weakening system also accelerated and on July 31, was downgraded to a tropical depression. However, Gil began to re-intensify on August 1, becoming a tropical storm again later that day. Initially expected to veer north of Hawaii, it continued west-northwest and began to approach the Hawaiian group on August 3. While passing through the island group, Gil reached its secondary peak intensity. Subsequently, Gil began to weaken once again as it threatened the Northwestern Hawaiian Islands. After passing through the islands, Gil was downgraded to a tropical depression on August 5. Several hours later, the storm dissipated. The remnants of the storm moved into the West Pacific late on August 6 and were last noted the next morning while passing south of Midway Island.

<span class="mw-page-title-main">Tropical Storm Flossie (2013)</span> Pacific tropical storm in 2013

Tropical Storm Flossie yielded stormy weather to Hawaii in late July 2013. The sixth tropical cyclone and named storm of the annual hurricane season, Flossie originated from a tropical wave that emerged off the western coast of Africa on July 9. Tracking westward across the Atlantic with little development, it passed over Central America and into the eastern Pacific Ocean on July 18, where favorable environmental conditions promoted steady organization. By 0600 UTC on July 25, the wave acquired enough organization to be deemed a tropical depression; it intensified into a tropical storm six hours later. Continuing westward, Flossie attained peak winds of 70 mph (110 km/h) on July 27 before entering the central Pacific Ocean. There, unfavorable upper-level winds established a weakening trend; on July 30, Flossie weakened to a tropical depression, and by 1200 UTC that same day, the storm degenerated into a remnant low, northeast of Kauai.

<span class="mw-page-title-main">Hurricane Iselle</span> Category 4 Pacific hurricane in 2014

Hurricane Iselle was the strongest tropical cyclone to make landfall on the Big Island of Hawaii in recorded history. The tenth named storm, fifth hurricane, and fourth major hurricane of the 2014 hurricane season, Iselle developed from an area of disturbed weather southwest of Mexico on July 31, 2014. Assuming a west-northwest course that it would maintain throughout its existence, generally favorable atmospheric conditions allowed for gradual strengthening, with the cyclone attaining hurricane status a day after formation. Continued strengthening progressed for several days up until August 4, when Iselle reached peak intensity with maximum sustained winds of 140 mph (220 km/h) and a minimum barometric pressure of 947 mbar, making it a Category 4 hurricane. Thereafter, Iselle encountered hostile environmental conditions and quickly weakened before making landfall on the Big Island on August 8 as a moderate tropical storm. Its passage over the island disrupted the cyclone, and Iselle later dissipated on August 9.

The following is a list of tropical cyclones by year. Since the year 957, there have been at least 12,791 recorded tropical or subtropical cyclones in the Atlantic, Pacific, and Indian Oceans, which are known as basins. Collectively, tropical cyclones caused more than US$1.2 trillion in damage, unadjusted for inflation, and have killed more than 2.6 million people. Most of these deaths were caused by a few deadly cyclones, including the 1737 Calcutta cyclone, the 1839 Coringa cyclone, the 1931 Shanghai typhoon, the 1970 Bhola cyclone, Typhoon Nina in 1975, the 1991 Bangladesh cyclone, and Cyclone Nargis in 2008.

<span class="mw-page-title-main">Hurricane Lane (2018)</span> Category 5 Pacific hurricane

Hurricane Lane was a powerful tropical cyclone that brought torrential rainfall and strong winds to Hawaii during late August 2018. The storm was the wettest on record in Hawaii, with peak rainfall accumulations of 58 inches (1,473 mm) along the eastern slopes of Mauna Loa. The twelfth named storm, sixth hurricane, fourth major hurricane, and the first of three Category 5 hurricanes of the record-breaking 2018 Pacific hurricane season, Lane originated from an area of low pressure that formed well southwest of Mexico on August 13. Tracking west through a region of favorable atmospheric and oceanic conditions, the system steadily intensified over the following days. It reached an initial peak as a Category 4 hurricane on August 18. Temporarily inhibited by more hostile conditions, the hurricane weakened slightly before regaining strength and reaching Category 5 status on August 22 to the south of Hawaii. Lane peaked with winds of 160 mph (255 km/h) and a barometric pressure of 926 mbar. Thereafter, the hurricane turned north and slowed. During this period, torrential rains battered much of the Hawaiian Islands. Unfavorable conditions again affected the hurricane, and it degraded to a tropical depression by August 28 before dissipating the following day.
