2010 Pacific hurricane season

The Pacific hurricane season officially started in 2010 in the eastern Pacific on 15 May and Zentralpazifk on June 1; it ended on 30 November. Within this period, usually make the most tropical storms, as only this time the appropriate conditions exist, such as a warm ocean, moist air and little wind shear. Any storms that form north of the equator and east of 180 ° W, belong to this basin. Storms that form in the west are no longer called hurricanes, typhoons but and are part of the Pacific typhoon season 2010.

Although the East Pacific basin to the West Pacific is the second most active formation region of tropical cyclones in the world, most storms threaten no country, because they usually give control to the open ocean. Few storms hit a curve to the east or north-east and then threaten especially the Mexican coast.

Season forecasts

On 27 May 2010, the Climate Prediction Center of the National Oceanic and Atmospheric Administration released its forecast for the Pacific hurricane season of 2010. This forecast is based on a below average active season of course. Accordingly, the meteorologists at the NOAA expect 9 to 15 named storms, of which 4-8 are developing into a hurricane. Of the hurricanes could 1 to 3, the intensity of major hurricanes - ie the categories 3-5 on the Saffir -Simpson Hurricane Scale - reach.

In the central Pacific, the Central Pacific Hurricane Center ( CPHC ) expected with 70 percent chance of a below-average active season. The 2010 expected climatic pattern has only a few tropical cyclones caused at historically present similarity in the central Pacific basin. First, the average Pacific is still in a long-term period of low activity, on the other hand expects the CHPC in the equatorial region of the pelvis either a neutral El Niño - Southern Oscillation and La Niña. Given these conditions is the CPHC assume that form in its area of ​​responsibility of two to three tropical systems. Result in an average season between the 140th and the 180th west longitude four to five tropical depressions, storms and hurricanes.

Storms

Tropical Storm Agatha

In the last week of May developed south of Central America has extensive tropical disturbance that slowly northwestward shifted and produced significant amounts of rain in the region. The National Hurricane Center issued on May 29, announced at 12:00 UTC clock that 785 km west of Managua, the Tropical Depression One -E formed. It intensified within a few hours to a tropical storm and was named Agatha. The system moved toward the coast of Guatemala in a north - northeasterly direction. It crossed near the border between Mexico and Guatemala, the coastline. About the mainland Agatha rapidly lost strength and was downgraded to a tropical depression. The NHC presented early established on May 30 that the system had no ground-level circulation more and explained the low pressure area for dissolved.

While the tropical system developed yet, it led across Nicaragua already to heavy rain, the effects demanded a human life. The induced precipitation of Agatha were extremely low by the train speed of the system in parts of Guatemala, so flash floods and landslides were triggered. At least 180 people were killed by landslides, flash floods and floods. The situation was aggravated by the eruption of the Pacaya volcano, Guatemala. Alone Guatemala has suffered at least 152 deaths, Honduras has 16 and 12 in El Salvador.

Tropical Depression Two -E

On June 12, the National Hurricane Center reported a tropical wave with monsoon- like properties. The next day, formed a low pressure area, the organization grew in the evening of June 15. On June 16, the NHC classified the system to Tropical Depression Two - E, which was almost stationary near the Gulf of Tehuantepec. At this point the system with continuous wind speeds of 45 km / h and a central pressure of 1007 hPa reached its greatest intensity. The conditions for further development were quite cheap, but in the next few hours, the strength of the system hardly changed.

The further development of the system was affected by the further west in the tropical disturbance that developed into Tropical Storm Blas on 17 June. On 17 June, the increased wind shear and demanded tribute from the system. The cyclone weakened and on 17 June the circulation disbanded.

Tropical Storm Blas

A few hundred kilometers south of Manzanillo slowly developed a tropical disturbance that on June 17, as far as organized that the NHC classified the system as Tropical Depression Three -E, but already 40 minutes later, the NHC announced that there is already a tropical storm has formed and assigned the name Blas. On June 19, Blas reached with continuous wind speeds of 100 km / h its greatest strength, then put a weakening of the storm due to a colder water surface and unfavorable conditions. Thus it weakened more and more on until it finally disbanded on 21 June.

Hurricane Celia

On June 17, in formation of a low pressure area which is increasingly organized and 550 km south- southeast of Acapulco developed tropical characteristics on June 19. Several hours later, the NHC classified the tropical depression to a tropical storm up and forgave the name Celia. The storm moved slowly at first in a west- southwesterly direction, but then turned to the west. Strong wind shear at first prevented rapid intensification, but this was soon back, and on June 20 Celia reached the first storm of the season hurricane strength.

The further intensification of the hurricane was then prevented by again increasing wind shear, but on the evening of June 21 the intensification had reinstated and Celia was upgraded to a Category 2 hurricane, the Saffir -Simpson Hurricane Scale.

The wind shear was the next day after Celia and intensified rapidly to reach their greatest intensity with winds of 260 kilometers per hour and an estimated pressure of 921 mbar. Not long after reaching this strength, the wind shear started to rise again and the system arrived in a stable environment with dry air. Over the following 42 hours, the sustained winds decreased to the strength of a tropical storm, and the system began a nearly stationary phase over the open sea. This continued until June 27. Despite the extremely unfavorable conditions succeeded the storm, to keep the status of a tropical storm until 28 June. On the evening of that day, the system was divided into a remnant low with little convective activity.

Hurricane Darby

On June 21, a large low pressure area to a tropical wave off the coast of Mexico organized slowly getting better. It was late on 22 June, classified as a tropical depression. The depression was increasingly organized better and was upgraded to a tropical storm on June 23 from NHC and was named Darby. Darby was intensifying rapidly, but slowed in the night from June 24. Nevertheless Darby reached the next morning about 375 km south- southwest of Puerto Escondido, Oaxaca the strength of a hurricane in the category 1 Intensification continued and on 25 June Darby became a major hurricane. The environment in which Darby was now, but became increasingly unfavorable, so the storm, reaching its climax with continuous wind speeds of 195 km / h and a minimum air pressure of 959 hPa. The next day, the hurricane weakened continuously and reached in the evening of June 26, only the strength of a tropical storm. The slowdown continued, and on 27 June was the gradation to a tropical depression. During the day, the NHC stopped the storm warnings because Darby had been transformed into a remnant low. The remnant low was later absorbed by the circulation of the Atlantic tropical storm Alex.

Tropical Depression Six -E

On 11 July, formed southwest of Central America, a low pressure system began to organize the next day. After a temporary Rückgäng of convection, the system was concentrated. After further development, the NHC classified the system late on July 14 as Tropical Depression Six -E. It slowed down more and more until it finally broke up three days later.

Tropical Storm Estelle

After an unusually inactive July, early August, formed off the coast of Mexico, a weather disturbance that is becoming increasingly better organized and was upgraded on August 5, to a tropical depression. After slow intensification of the system reached on August 6 the strength of a tropical storm and was named Estelle. On August 8, the storm showed signs of weakening. On August 9, Estelle was downgraded to a tropical depression. On 10 August, Estelle broke up.

Tropical Depression Eight -E

On August 3, a tropical wave came off of Africa's west coast and moved west across the Atlantic. She crossed Central America on 15 August and arrived in the eastern Pacific. Over the next five days, the system initially developed slowly. The meteorologists at the NHC did not go because of a further intensification of, but due to the evaluations of satellite imagery provides the NHC on August 20 at 12:30 UTC clock fixed, which has formed a tropical depression.

The system was at this time about 295 km west- southwest of Manzanillo in the Mexican state of Colima. Because of the existence of a subtropical ridge over northwestern Mexico and the area of ​​low pressure moved northwestward, and came into an area with moderate wind shear, so that further development was inhibited. When the system came on 21 August over cooler water, the convective activity declined and the tropical depression degenerated into a remnant low. This went on in an unchanged direction and dissipated over the open sea on 23 August completely.

Hurricane Frank

Tropical Depression Ten -E

A cloud area southwest of Mexico could be organized enough to be classified as a tropical depression on September 3. However, a further intensification did not take place, so that the NHC on September 4, spent his last warning to the depression in the evening. The system and its residual depth never reached land.

Tropical Depression Eleven -E ( Hermione )

The eleventh tropical depression of the season was a short-lived but destructive system. The low pressure area developed on 3 September rapidly from a low pressure area that was embedded in a trough. It strengthened rapidly as it approached the southeast coastline of Mexico. The system almost reached the status of a tropical storm, but then moved to Salina Cruz on land. Overland to the area of ​​low pressure weakened on September 4, within a few hours off to a remnant low. The heavy rain of the system led to flooding in the Mexican state of Oaxaca and triggered numerous landslides in Guatemala, whereby at least 54 people were killed.

The depression strengthened again in the Gulf of Mexico and became Tropical Storm Hermine.

Tropical Storm Georgette

Georgette had its origin in a tropical wave that broke up on September 1 of the west coast of Africa. On the way westward across the Atlantic Ocean, this wave left in a low- pressure system that has evolved into the Hurricane Karl on September 14. The shaft itself crossed the Caribbean Sea and arrived on 17 September in the eastern Pacific Ocean, where a significant development of the system was not expected. Finally, the system that wandered northwestward organized, on September 20, south of Baja California Sur but into a tropical depression. The system failed shortly afterwards intensify into a tropical storm and was named Georgette. On September 21, Georgette reached the greatest intensity with continuous one-minute wind speeds of 65 km / h and a minimum pressure of 999 hPa. During the day the storm hit the southern tip of Baja California before it weakened to a tropical depression. As such, Georgette moved northward, crossed the Gulf of California and arrived on 22 September, the Mexican mainland east of the Gulf. Early the next day the system disintegrated over northern Mexico.

Tropical Storm Omeka

About three weeks after the official end of the hurricane season in the Pacific basin was formed on 19 December a subtropical storm, near the International Date Line in the central Pacific. The storm moved first in a south-westerly direction, reached on the date line in the western Pacific Ocean, formed an eye and then drifted in a southerly and easterly direction and was after forming tropical characteristics on December 20 after re- crossing the date line as Tropical Storm Omeka classified. Finally, the system waved in a northeasterly direction. On 21 December, the Central Pacific Hurricane Center issued the last warning to the system. It was the first tropical storm in the central Pacific, which has formed since Tropical Storm Paka in 1997 out of season and the first tropical storm since Tropical Storm Olga in 2007, the North of the equator was in the month of December in the Western Hemisphere.
