Part of the 2006 Pacific hurricane season |
Hurricane Daniel was the second strongest hurricane of the 2006 Pacific hurricane season. The storm affected Hawaii late in its lifetime,causing moderate rainfall and minor damage. The fourth named storm,third hurricane,and second major hurricane of the season,Daniel originated on July 16 from a tropical wave off the coast of Mexico. It tracked westward,intensifying steadily to reach peak winds of 150 mph (240 km/h) on July 22. At the time,the characteristics of the cyclone resembled those of an annular hurricane. Daniel gradually weakened as it entered an area of cooler water temperatures and increased wind shear,and after crossing into the Central Pacific Ocean,it quickly degenerated into a remnant low on July 26,before dissipating two days later.
Initial predictions suggested that the cyclone would pass through the Hawaiian Islands as a tropical storm;however,Daniel's remnants dissipated southeast of Hawaii. The storm brought light to moderate precipitation to the Island of Hawaii and Maui,causing minor flooding,although no major damage or fatalities were reported.
Hurricane Daniel began as a tropical wave that moved off the west coast of Africa on July 2. The wave moved across the Atlantic Ocean and Caribbean Sea with little associated convection, and on July 12, it crossed Central America into the eastern Pacific Ocean. Convection increased on July 13, and two days later the system began to exhibit signs of tropical development to the south of Mexico. [1] It tracked westward at about 15 mph (25 km/h), and on July 16, the disturbance became better organized. [2] With convective rainbands near an associated low-level circulation, [3] it is estimated the tropical wave spawned a tropical depression late on July 16. At the time, it was located about 525 miles (845 km) south-southwest of Manzanillo, Colima. [1]
Classified as Tropical Depression Five-E, the system tracked westward under the steering currents of a mid-level ridge. [3] In the hours after formation, the depression lacked a concentration of deep convection near the center. Conditions favored development, including warm sea surface temperatures, very low amounts of wind shear, and an established anticyclone over the cyclone. [4] Convection became more centralized, coinciding with the improvement of upper-level outflow. Based on Dvorak classifications, it is estimated that the cyclone intensified into Tropical Storm Daniel at 12:00 UTC on July 17. [5] Daniel quickly became better organized, exhibiting increased thunderstorm activity and banding features. [6] A central dense overcast developed, and a well-defined rainband wrapped around the center of circulation. [7] Based on the formation of an eye feature, [8] the National Hurricane Center upgraded Daniel to hurricane status late on July 18 while it was located about 885 miles (1420 km) south-southwest of Cabo San Lucas. [1]
On July 19, the eye of Daniel became apparent on satellite imagery, [9] which organized into a pinhole eye. [10] It underwent an eyewall replacement cycle as it turned to the west-northwest, temporarily halting its intensification trend, before quickly strengthening and attaining major hurricane status on July 20. [1] Later that day, Hurricane Daniel organized into a very symmetric cyclone with a distinct eye about 30 miles (45 km) in diameter. Upon attaining Category 4 status on the Saffir-Simpson Hurricane Scale, the cyclone resembled the appearance of an annular hurricane; [11] an annular hurricane is one with a large and symmetric eye, surrounded by a thick ring of intense convection, and usually is able to maintain its intensity and structure for several days. [12] On July 21 the hurricane underwent another eyewall replacement cycle. After completing the cycle, Daniel attained its peak winds of 150 mph (240 km/h) early on July 22. It maintained peak winds for about 18 hours, and Daniel began a weakening trend as it crossed into an area of progressively cooler water temperatures. [1] The eye became more distinct on July 23, [13] before the cloud tops again warmed as the winds decreased. [14]
The hurricane crossed into the area of forecast responsibility of the Central Pacific Hurricane Center on July 24, [1] and upon doing so, its eye disappeared from satellite imagery. Daniel was forecast to track through the Hawaiian Islands as a tropical storm as water temperatures near the islands were warmer, [15] and wind shear was expected to be minimal. [16] However, it decelerated as the ridge to its north weakened, and due to the combination of cool waters and increasing easterly shear, Daniel weakened to a tropical storm on July 25. [1] Later that day, no active convection remained near the exposed circulation center, and early on July 26, it weakened to tropical depression status. Thunderstorm activity failed to redevelop, and Daniel degenerated into a remnant low-pressure area by 00:00 UTC on July 27. The remnant low continued west-northwestward, dissipating just southeast of the Big Island of Hawaii on July 28. [16]
When Hurricane Daniel was forecast to pass through the Hawaiian islands as a tropical storm, state and Hawaii County officials recommended residents prepare hurricane kits. They also suggested purchasing non-perishable foods and batteries. Initially, the storm was several days away from potentially affecting the state, and as a result, few residents rushed to prepare. [17] The Honolulu National Weather Service issued a high surf advisory for east facing beaches in Hawaii, and warned beachgoers to remain out of the water. [18] The National Weather Service issued a flash flood watch and wind advisory in association with the remnants of Daniel. [19]
The remnants produced 2–5 inches (50–125 mm) of rainfall throughout windward areas of the Big Island of Hawaii and Maui on July 28 and 29. [16] West Wailuaiki on Maui recorded 3.87 inches (98.3 mm) in one day, which was the highest daily rainfall total from the hurricane. [20] The storm also dropped precipitation on the East Maui watershed. [21] The rainfall particularly in Kailua-Kona on the Big Island caused ponding on roadways, as well as flooding of small streams. However, no injuries or serious damage were reported. [22] A station in Ka Lae briefly reported sustained winds of about 35 mph (56 km/h) with gusts to 45 mph (72 km/h). [16]
During the 61st Interdepartmental Hurricane Conference, the Hawaii State Civil Defense requested the retirement of the name Daniel, citing that it became one of the several storms memorable for threat or damage. [23] However, the World Meteorological Organization did not approve the request. [24]
The 2005 Pacific hurricane season was a near-average Pacific hurricane season which produced fifteen named storms, seven hurricanes and two major hurricanes. It was also the second consecutive season in which no tropical cyclone of at least tropical storm intensity made landfall. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year.
The 2003 Pacific hurricane season was the first season to feature no major hurricanes since 1977. The season officially began on May 15, 2003 in the Eastern North Pacific, and on June 1 in the Central ; both ended 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 featured 16 tropical storms, 7 of which intensified into hurricanes, which was then considered an average season. Damage across the basin reached US$129 million, and 23 people were killed by the storms.
The 2001 Pacific hurricane season was a relatively near-average Pacific hurricane season which produced fifteen named storms, though most were rather weak and short-lived. Only eight hurricanes formed and two major hurricanes. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year.
The 2000 Pacific hurricane season was an above-average Pacific hurricane season, although most of the storms were weak and short-lived. There were few notable storms this year. Tropical storms Miriam, Norman, and Rosa all made landfall in Mexico with minimal impact. Hurricane Daniel briefly threatened the U.S. state of Hawaii while weakening. Hurricane Carlotta was the strongest storm of the year and the second-strongest June hurricane in recorded history. Carlotta killed 18 people when it sank a freighter. Overall, the season was significantly more active than the previous season, with 19 tropical storms. In addition, six hurricanes developed. Furthermore, there were total of two major hurricanes.
The 1998 Pacific hurricane season was a fairly average Pacific hurricane season. Despite this, it had nine hurricanes and six major hurricanes, which was well above average. The season officially started on May 15 in the eastern Pacific and on June 1 in the central Pacific, and ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in that region. The first tropical cyclone developed on June 11, about ten days later than the normal start of the season. The final storm of the year, Hurricane Madeline, dissipated on October 20. Storm activity in the Central Pacific Hurricane Center's warning zone was low, with just one tropical depression observed in the region. Two tropical cyclones from the eastern Pacific also entered the central Pacific; the former did so as a hurricane.
The 1988 Pacific hurricane season was the least active Pacific hurricane season since 1981. It officially began May 15, in the eastern Pacific, and 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. The first named storm, Tropical Storm Aletta, formed on June 16, and the last-named storm, Tropical Storm Miriam, was previously named Hurricane Joan in the Atlantic Ocean before crossing Central America and re-emerging in the eastern Pacific; Miriam continued westward and dissipated on November 2.
Hurricane Fefa was the only tropical cyclone during the 1991 Pacific hurricane season to directly impact the Hawaiian Islands. The sixth tropical storm, fourth hurricane, and second major hurricane of the season, the storm developed from a tropical wave on July 29 about 975 miles (1,569 km) south-southeast of Cabo San Lucas. It moved west-northwestward, and under generally favorable conditions it strengthened to attain peak winds of 120 mph (190 km/h) on August 2. Fefa turned to the west towards Hawaii, and slowly weakened until dissipating near the island of Hawaii.
The 2007 Pacific hurricane season was a well below-average Pacific hurricane season, featuring only one major hurricane. The season officially started on May 15 in the eastern Pacific and on June 1 in the central Pacific, and ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in the region. The first tropical cyclone of the season, Alvin, developed on May 27, while the final system of the year, Kiko, dissipated on October 23. Due to unusually strong wind shear, activity fell short of the long-term average, with a total of 11 named storms, 4 hurricanes, and 1 major hurricane. At the time, 2007 featured the second-lowest value of the Accumulated cyclone energy (ACE) index since reliable records began in 1971. Two tropical cyclones – Cosme and Flossie – crossed into the central Pacific basin during the year, activity below the average of 4 to 5 systems.
The 2011 Pacific hurricane season was a below average season in terms of named storms, although it had an above average number of hurricanes and major hurricanes. During the season, 13 tropical depressions formed along with 11 tropical storms, 10 hurricanes and 6 major hurricanes. The season officially began 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 season's first cyclone, Hurricane Adrian formed on June 7, and the last, Hurricane Kenneth, dissipated on November 25.
The 2012 Pacific hurricane season was a moderately active Pacific hurricane season that saw an unusually high number of tropical cyclones pass west of the Baja California Peninsula. The season officially began on May 15 in the eastern Pacific Ocean, and on June 1 in the central Pacific (from 140°W to the International Date Line, north of the equator; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in these regions of the Pacific Ocean. However, the formation of tropical cyclones is possible at any time of the year. This season's first system, Tropical Storm Aletta, formed on May 14, and the last, Tropical Storm Rosa, dissipated on November 3.
Hurricane Kenneth was the strongest and longest-tracked hurricane of the 2005 Pacific hurricane season. The eleventh named storm and fifth hurricane of the season, Kenneth developed from a disturbance in the Intertropical Convergence Zone to the southwest of Mexico on September 14. It quickly attained peak winds of 135 mph (217 km/h) on September 18, before weakening due to increased wind shear and turning to a southwest drift. After weakening to tropical storm status, Kenneth attained a steady west-northwest motion and encountered favorable enough conditions for it to gain power and attain hurricane status on September 25. The cyclone again weakened as its motion halted, and on September 30 Kenneth dissipated a short distance off the Big Island of Hawaii. The remnants of Kenneth produced one of the highest rainfall totals in Hawaii, reaching up to 12 inches (300 mm) on Oahu. The rainfall caused flooding, though no major damage was reported.
The 2006 Pacific hurricane season was the first above-average season since 1997 which produced twenty-five tropical cyclones, with nineteen named storms, though most were rather weak and short-lived. There were eleven hurricanes, of which six became major hurricanes. Following the inactivity of the previous seasons, forecasters predicted that season would be only slightly above active. It was also the first time since 2003 in which one cyclone of at least tropical storm intensity made landfall. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year.
Hurricane Felicia was a powerful Category 4 Pacific hurricane whose remnants caused significant rainfall and flooding on the Hawaiian Islands. 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.
The 2009 Pacific hurricane season was the most active Pacific hurricane season since 1997. 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 Eastern Pacific tropical cyclone basin; however, tropical cyclone formation is possible at any time of the year. The first system of the season, Tropical Depression One-E, developed on June 18, and the last, Hurricane Neki, dissipated on October 27, keeping activity well within the bounds of the season.
Hurricane Darby was the first Eastern Pacific major hurricane since Hurricane Kenna in 2002. The sixth tropical cyclone, fourth named storm, and second hurricane of the 2004 Pacific hurricane season, Darby developed from a tropical wave that emerged from the west coast of Africa on July 12. After crossing into the Eastern Pacific, the storm became a tropical depression on June 26. The system steadily intensified, and became a hurricane on 000 UTC July 28. Darby peaked as a Category 3 hurricane on the Saffir-Simpson Hurricane Scale, though it quickly deteriorated due to cooler waters and increasing wind shear. While Darby dissipated on August 1, the remnants of the tropical cyclone affected the Hawaiian Islands. The system produced high waves and heavy rainfall that led to extensive flash flooding. Numerous roads were closed, while minor landslides and rockslides were reported. Despite the effects, no fatalities or severe damages occurred.
The 2016 Pacific hurricane season was tied as the fifth-most active Pacific hurricane season on record, alongside the 2014 season. Throughout the course of the year, a total of 22 named storms, 13 hurricanes and six major hurricanes were observed within the basin. Although the season was very active, it was considerably less active than the previous season, with large gaps of inactivity at the beginning and towards the end of the season. It officially started on May 15 in the Eastern Pacific, 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 these regions of the Pacific Ocean. However, tropical development is possible at any time of the year, as demonstrated by the formation of Hurricane Pali on January 7, the earliest Central Pacific tropical cyclone on record. After Pali, however, no tropical cyclones developed in either region until a short-lived depression on June 6. Also, there were no additional named storms until July 2, when Tropical Storm Agatha formed, becoming the latest first-named Eastern Pacific tropical storm since Tropical Storm Ava in 1969.
Hurricane Darby was a strong tropical cyclone which affected Hawaii as a tropical storm. The fifth named storm of the busy 2016 Pacific hurricane season, Darby originated from a low pressure area that developed in the Eastern Pacific well southwest of Mexico during July 2016. It gained sufficient organization to be declared a tropical depression on July 11, and was upgraded to Tropical Storm Darby the next day. Further intensification ensued, and Darby became a hurricane on July 13. Over the next three days, Darby slowly strengthened to Category 3 status on the Saffir–Simpson scale, becoming a major hurricane. Cool waters and dry air caused Darby to weaken over the next three days, although Darby managed to restrengthen slightly on July 21 before weakening once again as the storm neared Hawaii. Just after midnight on July 24, Darby made landfall on the Big Island. Darby weakened into a remnant low two days later.
The 2019 Pacific hurricane season was an above average season which produced nineteen named storms, most of which were rather weak and short-lived. Only seven hurricanes formed, the fewest since 2010. The season officially began 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. This season was one of the latest-starting Pacific hurricane seasons on record, with the first tropical cyclone, Hurricane Alvin, forming on June 25. The final system, Tropical Depression Twenty-One-E, dissipated on November 18.
The 2021 Pacific hurricane season was a moderately active Pacific hurricane season, with above-average activity in terms of number of named storms, but below-average activity in terms of major hurricanes, as 19 named storms, 8 hurricanes, and 2 major hurricanes formed in all. It also had a near-normal accumulated cyclone energy (ACE). The season officially began on May 15, 2021 in the Eastern Pacific Ocean, and on June 1, 2021, in the Central Pacific in the Northern Hemisphere. The season ended in both regions on November 30, 2021. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year, as illustrated by the formation of Tropical Storm Andres on May 9, which was the earliest forming tropical storm on record in the Eastern Pacific. Conversely, 2021 was the second consecutive season in which no tropical cyclones formed in the Central Pacific.
Hurricane Douglas was a strong tropical cyclone that became the closest passing Pacific hurricane to the island of Oahu on record, surpassing the previous record held by Hurricane Dot in 1959. The eighth tropical cyclone, fifth named storm, first hurricane, and first major hurricane of the slightly below-average 2020 Pacific hurricane season, Douglas originated from a tropical wave which entered the basin in mid-July. Located in favorable conditions, the wave began to organize on July 19. It became a tropical depression on July 20 and a tropical storm the following day. After leveling off as a strong tropical storm due to dry air, Douglas began rapid intensification on July 23, becoming the season's first major hurricane the following day and peaking as a Category 4 hurricane. After moving into the Central Pacific basin, Douglas slowly weakened as it approached Hawaii. The storm later passed north of the main islands as a Category 1 hurricane, passing dangerously close to Oahu and Kauai, causing minimal damage, and resulting in no deaths or injuries. Douglas weakened to tropical storm status on July 28, as it moved away from Hawaii, before degenerating into a remnant low on July 29 and dissipating on the next day.
