Hurricane Alvin (2019)
The 2019 Pacific hurricane season was a near average season which produced nineteen named storms, though most 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 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 season had a rather slow start, with no tropical cyclones forming in the basin during the month of May for the first time since 2016, and the first time that no storms formed before the month of June since 2011. The season became the latest-starting Pacific hurricane season on record since reliable records began in 1971 with the first tropical depression, which eventually became Hurricane Alvin, forming on June 25. The strongest hurricane of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2017 Pacific Hurricane Season
The 2017 Pacific hurricane season was significantly less active than the previous three Pacific hurricane seasons, featuring eighteen named storms, nine hurricanes, and four major hurricanes. Despite the considerable amount of activity, most of the storms were weak and short-lived. The season officially started on May 15 in the eastern 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 respective regions. However, the formation of tropical cyclones is possible at any time of the year, as illustrated in 2017 by the formation of the season's first named storm, Tropical Storm Adrian, on May 9. At the time, this was the earliest formation of a tropical storm on record in the eastern Pacific. The season saw near-average activity in terms of accumulated cyclone energy (ACE), in stark contrast to the extremely active seasons in 2014, 20 ...

2001 Pacific Hurricane Season
The 2001 Pacific hurricane season was a relatively near-average Pacific hurricane season which produced sixteen named storms, though most were rather weak and short-lived including one unnamed tropical storm which was operationally recognized as a tropical depression, the first such occurrence since 1996. 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 first storm of the season, Hurricane Adolph, formed on May 25 which became the strongest hurricane in the month of May at the time. Tropical Storm Barbara passed just north of Hawaii, bringing minimal impact. The most notable storm that year was Hurricane Juliette, which caused dev ...

1997 Pacific Hurricane Season
The 1997 Pacific hurricane season was a very active hurricane season. With hundreds of deaths and hundreds of millions of dollars in damage, this season was one of the costliest and deadliest Pacific hurricane seasons. This was due to the exceptionally strong 1997–98 El Niño event. 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 almost all tropical cyclones form in the northeastern Pacific Ocean. Several storms impacted land. The first was Tropical Storm Andres which killed four people and left another two missing. In August, Tropical Storm Ignacio took an unusual path, and its extratropical remnants caused minor damage in the Pacific Northwest and California. Linda became the most intense east Pacific hurricane in recorded history, a record it maintained until it was surpassed by Hurricane Patricia in 2015. Although it never m ...

1994 Pacific Hurricane Season
The 1994 Pacific hurricane season was the final season of the eastern north Pacific's consecutive active hurricane seasons that started in 1982. The 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. 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. A total of 10 hurricanes occurred, including five major hurricanes. The above average activity in 1994 was attributed to the ongoing 1990–95 El Niño at the time. Of note in this season is an unusual spree of very intense storms; the season was the first on record to see three Category 5 hurricanes, later tied in 2 ...

1992 Pacific Hurricane Season
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. The most notable storm was Hurricane Iniki, which caused billions of dollars of damage to the Hawaiian Islands, primarily in Kauai, along with six casualties. Hurricanes Lester, Virgil, Winifred, and Orlene also made landfall and killed several people, but were significantly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1966 Pacific Hurricane Season
The 1966 Pacific hurricane season started on May 15, 1966, and ended November 30, 1966. The season was of little note. Hurricane Blanca traveled 4,300 miles, setting a new record. During September and October of the year, Hurricane Helga and Tropical Storms Kirsten, Lorraine, and Maggie hitting Mexico. Kirsten caused 8 deaths and US$5.6 million (equivalent to $ million in ) in damages in Mexico.

Saffir–Simpson Scale
The Saffir–Simpson hurricane wind scale (SSHWS) classifies hurricanes—which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds. This measuring system was formerly known as the Saffir–Simpson hurricane scale, or SSHS. To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at 10 m above the surface of at least 74 mph (64 kn, 119 km/h; Category 1). The highest classification in the scale, Category 5, consists of storms with sustained winds of at least 157 mph (137 kn, 252 km/h). The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall. The Saffir–Simpson hurricane wind scale is based on the highest wind speed averaged over a one-minute interval 10 m above th ...

Tropical Storm Ivo (2019)
Tropical Storm Ivo was a tropical cyclone that brought heavy rainfall to five states in Mexico, causing severe flooding during August 2019. The tenth tropical cyclone and ninth named storm of the 2019 Pacific hurricane season, Ivo arose from a low-pressure area that spawned south of Guatemala on August 16. The low-pressure system gradually organized over the next several days as it tracked west-northwestward. The system coalesced into a tropical depression early on August 21 and strengthened into ''Tropical Storm Ivo'' several hours later. Located within a favorable environment of moist air and warm sea surface temperatures, the cyclone quickly intensified, peaking the next day with 1-minute maximum sustained winds of 70 mph (110 km/h) and a pressure of . Increasing wind shear caused the storm's intensification to level off later that day, as the system turned towards the north-northwest. Ivo passed by Clarion Island midday on August 23, generating winds of 60&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2014 Pacific Hurricane Season
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. Entering the season, expectations of tropical activity were high, with most weather agencies predicting a near or above average season. The season began with an active start, with three tropical cyclones developing before June 15, including two Category 4 hurricanes, of which one became the strongest tropical cyclone ever recorded in May in the East Pacific. After a less active period in late June and early July, activity once again picked up in late July. Activity increased in August, which featured four major hurricanes, and persisted throughout September and October. However, activ ...

Pacific Decadal Oscillation
The Pacific decadal oscillation (PDO) is a robust, recurring pattern of ocean-atmosphere climate variability centered over the mid-latitude Pacific basin. The PDO is detected as warm or cool surface waters in the Pacific Ocean, north of 20°N. Over the past century, the amplitude of this climate pattern has varied irregularly at interannual-to-interdecadal time scales (meaning time periods of a few years to as much as time periods of multiple decades). There is evidence of reversals in the prevailing polarity (meaning changes in cool surface waters versus warm surface waters within the region) of the oscillation occurring around 1925, 1947, and 1977; the last two reversals corresponded with dramatic shifts in salmon production regimes in the North Pacific Ocean. This climate pattern also affects coastal sea and continental surface air temperatures from Alaska to California. During a " warm", or "positive", phase, the west Pacific becomes cooler and part of the eastern ocean warms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
