Query: What was the first storm in the 2006 Pacific typhoon season?
The 2006 Pacific typhoon season was a near-average season that produced a total of 23 named storms, 15 typhoons, and six super typhoons. The season ran throughout 2006, though most tropical cyclones typically develop between May and October. The season's first named storm, Chanchu, developed on May 9, while the season's last named storm, Trami, dissipated on December 20. Also, this season was more active, costly, and deadly than the previous season.
The 1940 Pacific typhoon season marked an interruption in meteorological records in both the Philippines and Hong Kong due to the start of World War II. There were 43 reported tropical cyclones, including 27 that attained typhoon status. The first storm was observed in February, and the first typhoon formed two months later, killing three people along Mindanao. Several storms formed in June and July, including reports of a typhoon in the newspapers that killed 52 in South Korea, and another typhoon reported in newspapers that killed one person on Samar after dropping heavy rainfall. The strongest typhoon of the season originated in July and attained a minimum pressure of , as reported by a ship northeast of the Philippines.
The 1977 Pacific typhoon season was one of the least active Pacific typhoon seasons on record, with only 19 tropical storms forming. It was also the second of three known typhoon seasons during the satellite era (since 1960) to not produce a Category 5 equivalent super typhoon. (After the 1974 season and the 2017 season) The season's first storm, Severe Tropical Storm Patsy, formed on March 23 and the last, Typhoon Mary, dissipated on January 2, 1978. With Mary spanning two calendar years, it became the fourth typhoon to do so since 1945. Since then, two other typhoons have achieved this feat.
2018 opened with Tropical Depression Agaton active to the east of the Philippines. Over the course of two days, the system moved over to the South China Sea and intensified into the first named storm, Bolaven. A month later, Tropical Storm Sanba developed and affected the southern Philippines. About another month later, Tropical Depression 03W formed in the open Pacific and was named Jelawat. Jelawat intensified into the season's first typhoon on March 30, and then the season's first super typhoon. Tropical activity fired up by June, when a series of storms developed, with Tropical Storm Ewiniar making landfall over mainland China. Later that month, Typhoon Prapiroon developed and affected the Korean Peninsula, the first since 2013. Thereafter, Typhoon Maria developed and reached its peak intensity as a Category 5 super typhoon, being the first typhoon to reach that intensity since Typhoon Nock-ten in 2016. Hurricane Hector crossed the International Date Line on August 13, the first to do so since Genevieve in 2014. Systems like Tropical Storms Son-tinh, Ampil, Josie, Wukong, Jongdari, Shanshan, Yagi, Leepi, Bebinca, and Rumbia formed between late July to early August.
Hurricane Carlotta was the most powerful hurricane of the 2000 Pacific hurricane season. The third tropical cyclone of the season, Carlotta developed from a tropical wave on June 18 about 270 miles (470 km) southeast off the coast of Mexico. With favorable conditions for development, it strengthened steadily at first, followed by a period of rapid deepening to peak winds of 155 mph (250 km/h) on June 22. Cooler waters caused Carlotta to gradually weaken, and on June 25 it degenerated into a remnant area of low pressure while located about 260 miles (420 km) west-southwest of Cabo San Lucas.
Throughout the season, many typhoons made landfall at a higher intensity. Typhoon Saomai was the most powerful typhoon to strike China for over 50 years, as a Category 4 typhoon, responsible for over 400 deaths. Typhoon Shanshan struck Japan and became the costliest typhoon this season with a total damage of about $2.5 billion. The Philippines got hit by a total of six typhoons, which saw the highest number since 1974. All six typhoons were responsible for over 1,000 casualties and several millions of damages. Typhoon Ioke, which formed from the Central Pacific, entered the basin and became the strongest Central Pacific hurricane. Moreover, it was stated that the ratio of intense typhoons was 0.73, which was the highest since 1970.
Hurricane Adolph of the 2001 Pacific hurricane season was the first and one of only two East Pacific hurricanes in May to reach Category 4 strength on the Saffir-Simpson Hurricane Scale since record keeping began in the East Pacific.
Adolph was the first depression of the season, forming on May 25; it became a hurricane three days later. After rapidly intensifying, Adolph became the most powerful storm in terms of maximum sustained winds this season, along with Hurricane Juliette. The storm briefly threatened land before dissipating on June 1, after moving over colder waters.
In the first discussion bulletin, Forecaster Robbie Berg commented that it was the latest-forming tropical cyclone in the North Pacific east of 140°W since Tropical Depression Twenty-Two-E on November 24, 1987, and Kenneth was the latest forming named storm since Winnie in 1983. Kenneth strengthened to a major hurricane on November 22, becoming the latest-forming major hurricane in the eastern north Pacific basin in the satellite era. Kenneth was upgraded to Category 4 a few hours later, becoming the most powerful late-season storm ever recorded in the eastern north Pacific. However, 2015's Hurricane Sandra surpassed both records when it attained major hurricane status much later than Kenneth, being upgraded to a Category 4 on November 26, 2015.
The following names were used for named storms that formed in the North East Pacific in 2011. Names that were not used are marked in gray. This is the same list used in the 2005 season. No names were retired this year, so this list was used again in the 2017 season.
The 2000 Atlantic hurricane season was the first Atlantic hurricane season without a tropical cyclone in the month of July since 1993. The hurricane season officially began on June 1, and ended on November 30. It was slightly above average due to a La Niña weather pattern although most of the storms were weak. The first cyclone, Tropical Depression One, developed in the southern Gulf of Mexico on June 7 and dissipated after an uneventful duration. However, it would be almost two months before the first named storm, Alberto, formed near Cape Verde; Alberto also dissipated with no effects on land. Several other tropical cyclones—Tropical Depression Two, Tropical Depression Four, Chris, Ernesto, Nadine, and an unnamed subtropical storm—did not impact land. Five additional storms—Tropical Depression Nine, Florence, Isaac, Joyce, and Leslie—minimally affected land areas.
Typhoon Tip, known in the Philippines as Typhoon Warling, was the most intense tropical cyclone ever recorded. The forty-third tropical depression, nineteenth tropical storm, and twelfth typhoon of the 1979 Pacific typhoon season, Tip developed out of a disturbance from the monsoon trough on October 4 near Pohnpei. Initially, a tropical storm to the northwest hindered the development and motion of Tip, though after the storm tracked farther north, Tip was able to intensify. After passing Guam, Tip rapidly intensified and reached peak sustained winds of and a worldwide record-low sea-level pressure of on October 12. At its peak strength, it was also the second-largest tropical cyclone on record, with a wind diameter of , behind only Typhoon Winnie in 1997. Tip slowly weakened as it continued west-northwestward and later turned to the northeast, in response to an approaching trough. The typhoon made landfall in southern Japan on October 19, and became an extratropical cyclone shortly thereafter.
U.S. Air Force aircraft flew 60 weather reconnaissance missions into the typhoon, making Tip one of the most closely observed tropical cyclones. Rainfall from Tip indirectly led to a fire that killed 13 Marines and injured 68 at Combined Arms Training Center, Camp Fuji in the Shizuoka Prefecture of Japan. Elsewhere in the country, the typhoon caused widespread flooding and 42 deaths; offshore shipwrecks left 44 people killed or missing.
The 1990 Pacific hurricane season saw a then-record 16 hurricanes form. Throughout the year, 21 tropical cyclones became named storms in the eastern Pacific Ocean. Hurricane Alma formed on May 12, 1990, three days before the season's official start on May 15. The Central Pacific hurricane season began on June 1, covering tropical cyclone formation in the region between 140°W and International Dateline. Hurricane Trudy was the last storm to dissipate, doing so on November 1, nearly a month before the Pacific hurricane season officially ended on November 30.
The 1990 Pacific hurricane season was a very active season which observed 21 named storms within the basin. The season also produced the fourth highest ACE index value on record. The season was 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 slightly exceeded when Hurricane Alma formed on May 12.
Tropical cyclogenesis first occurred in the month of June, with two tropical depressions developing in the Atlantic. However, no tropical cyclones developed in the month of July, the first phenomenon since 1993. In August, five tropical cyclones developed, most notably, Hurricane Alberto. September was more active, with seven named storms forming; that month featured Hurricane Keith, the strongest system of the 2000 Atlantic hurricane season. With seven named storms forming in September, this made it the most active September on record at the time. This record was surpassed two years later when eight storms formed in September. In addition, a quick succession of eight storms occurred in September, and lasted into early October. Six tropical cyclones existed in October and one additional subtropical storm developed in the last week of the month. Following an active October, no tropical cyclogenesis occurred in November, which is the final month of the season.
Typhoon Omar of 1992, known in the Philippines as Typhoon Lusing, was the strongest and costliest typhoon to strike Guam since Typhoon Pamela in 1976. The cyclone formed on August 23 from the monsoon trough across the western Pacific Ocean. Moving westward, Omar slowly intensified into a tropical storm, although another tropical cyclone nearby initially impeded further strengthening. After the two storms became more distant, Omar quickly strengthened into a powerful typhoon. On August 28, it made landfall on Guam with winds of 195 km/h (120 mph). The typhoon reached its peak intensity the next day, with estimated 1‑minute winds of 240 km/h (150 mph), making it a "super typhoon" according to the Joint Typhoon Warning Center (JTWC). Omar weakened significantly before striking eastern Taiwan on September 4, proceeding into eastern China the next day and dissipating on September 9.
Only two major hurricanes—storms of Category 3 intensity or higher—formed during the season, the least since the 1997 season, although tied with the 2006 and 2002 seasons. Named storms were active for 33.50 days during the season, the lowest number of active days since the 1994 season. There were only 11.25 days with active hurricanes, the lowest value since the 2002 season. Despite this, the number of days with major hurricanes was above the long-term average. Four named storms made landfall on the U.S. during the year, but damage from those storms totaled to only about $82 million (2007 USD); this was the least damage the U.S. saw from any Atlantic hurricane season since the 1990 season. The season was one of only six Atlantic hurricane seasons to produce two Category 5 equivalent hurricanes, the others being the 1932, 1933, 1961, 2005, and 2017 seasons. The two Category 5 hurricanes, Dean and Felix, both reached Category 5 strength on two separate occasions, and both made landfall at Category 5 intensity, making the 2007 season the first to feature two hurricanes doing each, both of which would not be repeated until 2017. When Hurricane Felix was upgraded to a Category 5 storm on September 2, it became the eighth to form in this basin since 2000. This gave the decade more hurricanes of such strength than any other on record.
The 1995–96 South-West Indian Ocean cyclone season was a moderately active season that included Cyclone Bonita, which was the first known tropical cyclone to cross from the southern Indian Ocean into the southern Atlantic Ocean. Tropical activity lasted for about six months from the middle of November 1995 to early May 1996. The first storm, Intense Tropical Cyclone Agnielle, formed in the adjacent Australian basin on November 16 and later reached peak winds in the south-west Indian Ocean. The next named storm after Agnielle was Bonita, which formed in early January and killed 42 people. The basin was most active in February, with two tropical cyclones, or the equivalent of a minimal hurricane, as well as a severe tropical storm. The first of these three was Doloresse, which killed 67 people due to a shipwreck in the Comoros. The next storm was Cyclone Edwige, which caused heavy crop damage on Mauritius before looping along the east coast of Madagascar. In March, both Cyclone Flossy and Tropical Storm Guylianne passed near the Mascarene Islands, producing heavy rainfall and gusty winds.
The hurricane season officially began on June 1, though the first tropical cyclone developed on May 21. A total of 21 tropical and subtropical cyclones formed, but just 10 of them intensified into nameable storm systems. This was about average compared to the 1950–2000 average of 9.6 named storms. Six of these reached hurricane status, around the 1950–2000 average of 5.9. Furthermore, three storms reached major hurricane status; close to the 1950–2000 average of 2.3. Collectively, the cyclones of this season caused at least 84 deaths and about $101.63 million in damage. The Atlantic hurricane season officially ended on November 30, with the final cyclone becoming extratropical on October 28.
Typhoon Mike was the strongest typhoon to strike the Philippines since Typhoon Irma in November 1981. Mike was also the most severe typhoon to hit the Philippines since Typhoon Ike during September 1984, which killed over 1,000 people. The typhoon destroyed a television broadcast tower, radio towers, electric cables and bridges, which resulted in widespread power outages and several radio stations briefly went off air. Hundreds of villages were also rendered impassable.
At the end of September 1979, three circulations developed within the monsoon trough that extended from the Philippines to the Marshall Islands. The westernmost disturbance developed into a tropical depression on October 1, to the west of Luzon, which would later become Typhoon Sarah on October 7. On October 3, the disturbance southwest of Guam developed into Tropical Storm Roger, and later on the same day, a third tropical disturbance that would later become Typhoon Tip formed south of Pohnpei. Strong flow from across the equator was drawn into Roger's wind circulation, initially preventing significant development of the precursor disturbance to Tip. Despite the unfavorable air pattern, the tropical disturbance gradually organized as it moved westward. Due to the large-scale circulation pattern of Tropical Storm Roger, Tip's precursor moved erratically and slowly executed a cyclonic loop to the southeast of Chuuk. A reconnaissance aircraft flight into the system late on October 4 confirmed the existence of a closed low-level circulation, and early on October 5, the Joint Typhoon Warning Center (JTWC) issued its first warning on Tropical Depression Twenty-Three-W.
While executing a loop near Chuuk, the tropical depression intensified into Tropical Storm Tip, though the storm failed to organize significantly due to the influence of Tropical Storm Roger. Reconnaissance aircraft provided the track of the surface circulation, since satellite imagery estimated the center was about from its true position. After drifting erratically for several days, Tip began a steady northwest motion on October 8. By that time, Tropical Storm Roger had become an extratropical cyclone, resulting in the southerly flow to be entrained into Tip. An area of a tropical upper tropospheric trough moved north of Guam at the time, providing an excellent outflow channel north of Tip. Initially, Tip was predicted to continue northwestward and make landfall on Guam, though instead, it turned to the west early on October 9, passing about south of Guam. Later that day, Tip intensified to attain typhoon status.
The 1997–98 South-West Indian Ocean cyclone season was fairly quiet and had the latest start in 30 years. The first tropical disturbance originated on January 16, although the first named storm, Anacelle, was not upgraded until February 8, a record late start. The last storm to dissipate was an unusually late tropical depression in late July. Many of the storms suffered from the effects of wind shear, which contributed to there being only one tropical cyclone – equivalent to a minimal hurricane. The season also occurred during a powerful El Niño.
Typhoon Imbudo was the strongest typhoon to strike Luzon since Typhoon Zeb five years prior, and was the fifth storm in eight weeks to affect the country. The typhoon left widespread areas flooded for several days. Cagayan Valley was largely isolated after a bridge was damaged in Ilocos Norte. Damage was heavy in the region, totaling P2.2 billion (PHP, $40 million USD), and over 80,000 people were displaced by the storm. Damage was heaviest in Isabela, where damage was estimated at P1.9 billion (PHP, $35 million USD), mostly to crops and killed livestock. There, winds and rain knocked down trees and caused a province-wide power outage. Most trees less than three years old fell during the high winds. In Isabela province, the banana crop was almost entirely destroyed, and most of the corn and rice crops were heavily damaged. The high damage caused the gross regional product, or overall economy of the Cagayan Valley, to decrease by 0.3% than what would have happened without the typhoon.
The 1998 season was very weak compared to the 1997 season; this was due to the strong El Niño in the previous season. During the 1998 season, a total of 28 tropical depressions developed across the western Pacific basin. Of those 28 depressions, a total of 18 strengthened into tropical storms of which 9 further intensified into typhoons. The first tropical cyclone developed on May 28, marking the fourth latest start to any Pacific typhoon season on record, and the last one dissipated on December 22. The Philippine region also set a record: with only eleven storms forming or moving into its area of responsibility, PAGASA had its quietest season as of 2006.
The 2006 Pacific typhoon season was characterized by a large number of intense typhoons despite a near-normal number of named storms. According to the Joint Typhoon Warning Center (JTWC), the year featured seven super typhoons, the third-highest since reliable records began in 1970. This was partially attributed to the presence of an El Niño, especially toward the latter half of the season. Though not a strong ENSO event, it peaked during November and coincided with a series of powerful typhoons impacting the Philippines. Meteorologist Gary Padgett regarded the event as, "a veritable parade of intense [and] destructive typhoons." The first of these storms was Typhoon Xangsane in late September which explosively intensified shortly after its formation near Samar Island. The storm killed more than 200 people in the country and inflicted 5.9 billion PHP (US$150 million) in damage. In late October, Typhoon Cimaron became one of the most intense storms to strike Luzon; however, it impacted a sparsely populated region and relatively few casualties took place. Less than three weeks later, a Typhoon Chebi followed a similar path to Cimaron, though its small size contributed to relatively limited damage. Typhoon Durian would become the fourth of these powerful storms to impact the country. The final typhoon in the "parade" was Utor in December, which was the weakest of the five and followed a more southerly track.
The season started on January 4 with the formation of Tropical Depression 01W to the west of Yap, with the first tropical storm developing a few months later on April 1, and ended near the end of the year when Tropical Storm Bobbie dissipated in the open Pacific on December 25. During the season, 25 systems either threatened land or made landfall, killing over 2,400 people. The strongest storm of the season was Super Typhoon Doug, which affected Taiwan, South Korea and mainland China, while the deadliest storm was Super Typhoon Fred, which killed over 1,000 people in China. Earlier in the season, the combined effects of two tropical storms —Russ and Sharon —caused flooding in China that killed over 1,400. The season also saw two storms, Li and John, cross into the Western North Pacific from the east, while one storm, Tropical Storm Yuri, formed from a precursor low that had similarly crossed the International Date Line. This season, PAGASA named 25 systems and had to use an auxiliary list to name some of them after running out of names from their standard list. Of the 25, three systems were not tracked by the Joint Typhoon Warning Center.
On March 7, Tropical Storm Risk issued its first forecast for the season at an extended-range, forecasting a close to average season of 27 tropical storms, 17 typhoons and 8 intense typhoons. The ACE predicted was around 298. By May 5, Tropical Storm Risk issued their second forecast for the season, raising their numbers to 29 tropical storms, 19 typhoons and 9 intense typhoons, with an ACE of 326. This is due to the observed warming of sea-surface temperatures in the Niño 3.75 region and current patterns within the Central Pacific, indicating slightly higher activity. TSR released its third forecast for the season on June 7, predicting the same numbers with the same reason. Though on their fourth forecast during July 5, TSR stated that the 2006 season will be 15% above the 1965–2005 norm. Therefore, they raised the number of intense typhoons to 10, and their ACE to 349. The other reason behind this is due to the fact that there was an increase in tropical activity and much warmer SSTs over in the Niño 3.75 region than the previous forecast. On August 4, TSR released their final forecast. They reduced the number of intense typhoons to 9, and the ACE to 325. This was because it was reported that a slight decrease in tropical activity from the previous forecast and is due solely of a slight decrease in SSTs over in the same region.
