Part of the 2004 Pacific hurricane season |
Hurricane Javier was a powerful tropical cyclone whose remnants brought above-average rainfall totals across the western United States in September 2004. Javier was the tenth named storm,the sixth hurricane and the final major hurricane of the 2004 Pacific hurricane season. Javier was also the strongest hurricane of the 2004 season,with 150 mph (240 km/h) winds and a central pressure of 930 millibars (27.46 Hg). However,because of high wind shear in the East Pacific,Javier weakened rapidly before making landfall in Baja California as a tropical depression. The remnants of the storm then continued moving northeast through the Southwestern United States. Javier caused no direct fatalities,and the damage in Mexico and the United States was minimal.
On August 29, a tropical wave moved off the western coast of Africa. It tracked westward across the Atlantic basin, remaining devoid of deep convection—intense shower and thunderstorm activity—for several days. The disturbance interacted with a cold-core low in the vicinity of the Leeward Islands, and both features continued west across the Caribbean Sea. The wave crossed Central America on September 9 as convection steadily increased, and development of thunderstorm activity continued as it entered the East Pacific basin. [1] Despite featuring limited outflow owing to modest easterly wind shear, [2] the system acquired sufficient organization to be deemed a tropical depression around 18:00 UTC on September 10. The newly designated Tropical Depression Thirteen-E was located approximately 345 mi (555 km) south-southeast of Salina Cruz, Oaxaca, at this time. [1]
Within a few hours of formation, the cyclone began to develop a small central dense overcast-like feature and some associated rainbands. [3] This increase in organization suggested that it strengthened into Tropical Storm Javier around 12:00 UTC on September 11. Over the coming days, a subtropical ridge positioned over Mexico directed Javier on a west-northwest to northwest track offshore the coastline of Mexico. [1] As the storm's convective appearance continued to mature, including the development of an eye and a rainband wrapping throughout the northwestern semicircle, [4] it strengthened into a hurricane around 18:00 UTC on September 12. Javier continued to experience light northeasterly wind shear as it had since the system originally formed, resultant from an upper-level anticyclone focused over the Gulf of California. In spite of this shear, the cyclone soon began a period of rapid intensification as it developed a clear eye embedded within convection as cold as −112 °F (−80 °C). [5] Javier attained major hurricane—Category 3 or greater on the Saffir–Simpson scale—intensity around 12:00 UTC on September 13, and within 12 hours it reached its peak intensity as a strong Category 4 hurricane. Satellite intensity estimates suggested the system attained winds of 150 mph (240 km/h) and a minimum barometric pressure of 930 mb (27 inHg), translating to a 65 mph (100 km/h) increase in winds and a 49 mb (1.4 inHg) drop in central pressure over the course of just 24 hours. [1]
Early on September 14, Javier's small eye became cloud filled, and imagery of the system's internal structure suggested it was undergoing an eyewall replacement cycle. As this process underfolded but the hurricane otherwise remained within favorable conditions, Javier persisted as a Category 3–4 cyclone until early on September 17. By that time, the storm was entering cooler sea surface temperatures and strong southwesterly wind shear, [1] and those inhibitors were exacerbated by plentiful mid- to upper-level dry air near the cyclone. The system began to lose its associated convective activity, [6] which caused it to weaken under hurricane strength around 12:00 UTC on September 18. Javier was further reduced to a tropical depression within 12 hours. The weakening tropical depression moved onshore Baja California between Cabo San Lázaro and Punta Abreojos around 11:00 UTC on September 19. As it moved north and then north-northeast, it crossed into the Sea of Cortes. [1] Having lacked thunderstorm activity for over 18 hours by that point, [7] the fledging system degenerated to a remnant low around 18:00 UTC that day. The circulation moved into mainland Mexico near Guaymas and dissipated over the mountainous terrain of Sonora on September 20. [1]
Javier's strength was difficult to forecast. In its formation stages many of the forecast models gave out a complex suggestions of where the storm should go. One of the models forecast the storm to move west for a couple of days and then stall offshore and then turn east and hit western Guatemala. [8] The rapid intensification was also difficult to forecast compared to average forecast errors in a ten-year period. [1] Mexican officials began issuing tropical storm watches on September 15 as Javier paralleled the west coast of Mexico. [9] The warnings for western mainland Mexico were then dropped as the storm did not recurve as predicted. However, more tropical storm warnings were issued for Baja California and northwestern Mexico as Javier was located 300 kilometres (186 mi) southwest of Baja California. Forecasters predicted that Javier would bring a storm surge of 1–3 feet, (0.3–1 meters)rainfall of 3-6 inches (7.6-15.2 cm), and strong rip currents. The National Hurricane Center, predicted that Javier will parallel the Baja California coastline according to their forecast models and recurve as a weak storm and dissipate over the Southwestern United States. [10] On September 18, Mexican officials discontinued the warnings for Baja California when Javier weakened to a tropical depression before making landfall. [11]
Winds up to tropical storm force were reported by ships at sea. [1] On land, the storm dropped 3.14 inches (80 mm) of rain in Bacanuchi, Mexico. [12] Javier's flooding rains damaged portions of highway 1 near Vizcaino and three fishermen were reported missing when their ship was lost during the storm. [13] [14] In addition, oil prices began to climb when Javier passed through the area. [15] However, overall damage in Baja California was minimal.
In Arizona, the remnants of Javier dropped widespread, light to moderate rainfall, improving topsoil moisture and greatly affecting a prolonged drought in the Southwestern United States. Maximum rainfall in the state reached 7 in (180 mm) in Walnut Creek. [16] [17] [18] In Tucson, the airport received rainfall of 0.37 inches (93 mm) while the University of Arizona reported 0.89 inches (26 mm) of rain. Lightning and rain from Javier delayed the University of Arizona Wildcats football game against the Wisconsin Badgers for 88 minutes late in the second quarter, and flooding closed several roads. [19] Grand Canyon, Arizona received 3.30 inches (84 mm) of rain, exactly one fifth of its yearly average. [17] The remnants of Javier also dropped 1-3 inches of rain across Utah, Colorado, New Mexico, Texas and the upper Midwest. [16] In terms of point maxima, Javier is the rainiest tropical cyclone on record in the period 1972 — 2008 in Wyoming and North Dakota. [20]
The 2004 Pacific hurricane season was unusual in that no tropical cyclones of at least tropical storm intensity made landfall, the first such occurrence since 1991. The season was also below-average in terms of named storms and hurricanes, near-average in terms of major hurricanes. The season officially began on May 15 in the eastern Pacific, and on June 1 in the central Pacific; it officially ended in both basins on November 30. These dates conventionally delimit the period during each year when a majority of tropical cyclones form. The season was reflected by an accumulated cyclone energy (ACE) index of 71 units.
The 2005 Pacific hurricane season was a near-average season which produced fifteen named storms, only seven hurricanes formed 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 – 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.
The 1993 Pacific hurricane season included more than double the average number of major hurricanes – Category 3 or stronger cyclones on the Saffir–Simpson scale. This activity was the result of an El Niño event, which is the main factor contributing to above-average activity across the Pacific basin. The season featured 15 named storms, 11 hurricanes, and 9 major hurricanes. While the number of named storms was near the long-term average, the number of hurricanes was above the average of 8, and the number of major hurricanes far exceeded the long-term average of 4. Seasonal activity began on May 17 and ended on November 8, within the confines of a traditional hurricane season which begins on May 15 in the East Pacific and June 1 in the Central Pacific. The season ends on November 30 in both basins. These dates conventionally delimit the period during each year when most tropical cyclones form.
The 2008 Pacific hurricane season was a near-average Pacific hurricane season which featured seventeen named storms, though most were rather weak and short-lived. Only seven hurricanes formed and two major hurricanes. This season was also the first since 1996 to have no cyclones cross into the central Pacific. The season officially began on May 15 in the eastern Pacific and on June 1 in the central Pacific. It ended in both regions on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclone formation occurs in these regions of the Pacific. This season, the first system, Tropical Storm Alma, formed on May 29, and the last, Tropical Storm Polo, dissipated on November 5.
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.
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. Only eleven hurricanes formed and six 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 at least one cyclone of 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.
Tropical Depression Sixteen-E was the final tropical cyclone of the 2004 Pacific hurricane season. The storm developed out of a tropical wave that moved off the western coast of Africa on October 8. The wave crossed the Atlantic Ocean and entered the eastern Pacific on October 18. The system began to gradually organize, and on October 25 it was classified as a tropical depression. The storm did not significantly intensify, as wind shear prevented it from attaining tropical storm status. The short-lived depression moved northward, and made landfall in Mexico on October 26. Quickly deteriorating, the system dissipated shortly thereafter, although its remnants persisted for a couple more days. The depression had no major effects on land. However, it produced heavy rainfall in parts of Mexico, and the remnants triggered thunderstorms over the southwestern United States.
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.
The 2015 Pacific hurricane season is the second-most active Pacific hurricane season on record, with 26 named storms, only behind the 1992 season. A record-tying 16 of those storms became hurricanes, and a record 11 storms further intensified into major hurricanes throughout the season. The Central Pacific, the portion of the Northeast Pacific Ocean between the International Date Line and the 140th meridian west, had its most active year on record, with 16 tropical cyclones forming in or entering the basin. Moreover, the season was the third-most active season in terms of accumulated cyclone energy, amassing a total of 290 units. The season 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 the Northeast Pacific basin. However, the formation of tropical cyclones is possible at any time of the year. This was shown when a tropical depression formed on December 31. The above-average activity during the season was attributed in part to the very strong 2014–16 El Niño event.
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.
The 2017 Pacific hurricane season was an above average Pacific hurricane season in terms of named storms, though less active than the previous three, 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 basin proper. The season saw near-average activity in terms of accumulated cyclone energy (ACE), in stark contrast to the extremely active seasons in 2014, 2015, and 2016; and for the first time since 2012, no tropical cyclones formed in the Central Pacific basin. However, for the third year in a row, the season featured above-average activity in July, with the ACE value being the fifth highest for the month. Damage across the basin reached $375.28 million (2017 USD), while 45 people were killed by the various storms.
Hurricane Blanca in 2015 was the earliest recorded tropical cyclone to make landfall on the Baja California Peninsula. Forming as a tropical depression on May 31, Blanca initially struggled to organize due to strong wind shear. However, once this abated, the system took advantage of high sea surface temperatures and ample moisture. After becoming a tropical storm on June 1, Blanca rapidly intensified on June 2–3, becoming a powerful Category 4 hurricane on the Saffir–Simpson hurricane wind scale; maximum sustained winds reached 145 mph (230 km/h) at this time. The hurricane's slow motion resulted in tremendous upwelling of cooler water, resulting in a period of weakening. Blanca gradually recovered from this and briefly regained Category 4 status on June 6 as it moved generally northwest toward the Baja California peninsula. Cooler waters and increased shear again prompted weakening on June 7 and the system struck Baja California Sur on June 8 as a weak tropical storm. It quickly degraded to a depression and dissipated early the next day.
Hurricane Sandra was the latest-forming major hurricane in the northeastern Pacific basin, the strongest Pacific hurricane on record in November, and the record eleventh major hurricane of the 2015 Pacific hurricane season. Originating from a tropical wave, Sandra was first classified as a tropical depression on November 23 well south of Mexico. Environmental conditions, including high sea surface temperatures and low wind shear, were highly conducive to intensification and the storm quickly organized. A small central dense overcast developed atop the storm and Sandra reached hurricane status early on November 25 after the consolidation of an eye. Sandra reached its peak intensity as a Category 4 hurricane on the Saffir–Simpson hurricane wind scale with winds of 150 mph (240 km/h) and a pressure of 934 mbar early on November 26. Thereafter, increasing shear degraded the hurricane's structure and weakening ensued. Rapid weakening took place on November 27 and Sandra's circulation became devoid of convection as it diminished to a tropical storm that evening. The cyclone degenerated into a remnant low soon thereafter and ultimately dissipated just off the coast of Sinaloa, Mexico, on November 29.
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 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 2020 Pacific hurricane season was the least active Pacific hurricane season since 2011. Altogether, 21 tropical cyclones developed. The season was near average in terms of tropical storms, featuring a total of 17, but had a well below average number of hurricanes and major hurricanes, with only 4 hurricanes and 3 major hurricanes forming. Additionally, no tropical cyclones formed in the Central Pacific basin for the first time since 2017, marking the start of a series of seasons with no tropical cyclogenesis occurring there. The season officially began on May 15 in the East 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 the respective regions. However, the formation of tropical cyclones is possible at any time of the year, as illustrated in 2020 by the formation of the season's first system, Tropical Depression One-E, on April 25. This the earliest formation of a tropical cyclone on record in the eastern Pacific basin proper.
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, with 17 named storms, 8 hurricanes, and 2 major hurricanes forming 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.
The 2022 Pacific hurricane season was a fairly active Pacific hurricane season, with nineteen named storms, ten hurricanes, and four major hurricanes forming. Also, it was the third consecutive season in which no tropical cyclones formed in the Central Pacific Ocean. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; both ended on November 30. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention.
Hurricane Dolores was a powerful and moderately damaging tropical cyclone whose remnants brought record-breaking heavy rains and strong winds to California. The seventh named storm, fourth hurricane, and third major hurricane of the record-breaking 2015 Pacific hurricane season, Dolores formed from a tropical wave on July 11. The system gradually strengthened, attaining hurricane status on July 13. Dolores rapidly intensified as it neared the Baja California peninsula, finally peaking as a Category 4 hurricane on the Saffir–Simpson scale with winds of 130 mph (215 km/h) on July 15. An eyewall replacement cycle began and cooler sea-surface temperatures rapidly weakened the hurricane, and Dolores weakened to a tropical storm two days later. On July 18, Dolores degenerated into a remnant low west of the Baja California peninsula.
