2012 Pacific hurricane season

The Pacific hurricane season began in 2012 in the eastern Pacific officially on May 15, and in the central Pacific Ocean on June 1. It ended on 30 November. During this period, usually form the most tropical storms, since in this period good conditions for the formation of hurricanes are present, the ocean is warm enough, the humidity is high and little wind shear, however, a tropical storm could form at any time. All storms north of the equator and east of 180 ° W are included. The storms that form west of 180 ° W, are called typhoons, and are part of the Pacific typhoon season of 2012.

The season started early with the formation of Tropical Storm Aletta on May 14, one day before the official start of the hurricane season. With Hurricane Bud for a week, the first hurricane of the season developed by Aletta. Bud reached the strength of a major hurricane, but weakened before landfall on the coast of Jalisco to a tropical storm off. Hurricane Carlotta also came overland. Carlotta led to the deaths of at least seven people. The next two hurricanes, Daniel and Emilia, a similar course was followed to the west on the open Pacific Ocean and located intenvisierten both in a major hurricane. Shortly after Emilia Fabio also developed and was thus the last of a series of three hurricanes in July. After Fabio's resolution, it was quiet. It was not until 7 August to Gilma, but far away of which formed from land and thus also threatened no land developed. On the day of the dissolution of Gilma an area of low pressure air could develop on the Mexican Pacific coast that was on the same day to Tropical Storm Hector. Hector initially threatened no land, only its remnant low caused rain in Mexico. After Hurricane Ileana to brink August / September followed by the weak tropical storms John and Kristy, but that influenced both Mexico weather. Lane developed on September 15, far out in the Pacific and thus threatened no land. The end of September could be formed from an area of low pressure air on the coast of Mexico Tropical Storm Miriam, which rapidly into a major hurricane strengthened and its remnant low -influenced parts of northern Mexico and Texas. On Miriam followed Norman, who could form in the extreme south of the Gulf of California on September 28. He developed only in a weak tropical storm and went as a tropical depression over Sinaloa ashore. After a week of silence Tropical Storm Olivia was formed on October 6, which was rapidly from an area of low pressure air. Paul formed at the end of the 2nd week of October and began a rapid intensification before he goes over Baja California on land. The last storm of the season, Pink, formed on October 30th and dissipated on November 3.

Storms

Tropical Storm Aletta

On May 12, about 890 km south-southwest formed from Acapulco, Mexico, a tropical disturbance. The disturbance moved quickly to the northwest before it was stationary and began to deepen rapidly. After the assessment of the National Hurricane Center (NHC ), the system intensified early on May 14 to Tropical Depression One -E, the first of the season in the eastern Pacific Ocean. The low pressure area formed one day before the official start of the hurricane season of 2012 and was since Tropical Storm One -E on May 13, 1996, the first tropical system that has formed in the eastern Pacific before the official start of the hurricane season. Early on May 15, the low pressure area to Tropical Storm Aletta classified the NHC high. The next day Aletta reached its peak with winds of 85 km / h and a minimum air pressure of 1000 hPa Later, on 16 May Aletta met on an area with increasing wind shear and dry air. Therefore, the storm weakened to a weak tropical storm off, the wind speeds of just 65 km / h possessed. A few hours later, the National Hurricane Center announced that Aletta was still only a tropical depression, which is increasingly lost to convection after it had struck a west- northwesterly cyclone track. In the course of May 17 Aletta lost a large part of the convection, but he could regenerate approximately when the storm turned north. The next day the storm convection in the west and the south lost because of strong wind shear completely. Aletta moved to the northeast, and the slowdown continued, before Aletta became extratropical on 19 May and einschwenkte on an eastward track. Aletta remains then moved quickly and without thunderstorm activity to the west until it completely broke up on May 21.

Hurricane Bud

On May 12, a low pressure area formed south of East Panama. The system slowly organized as it moved west. Since the storm on 15 May showed convection, he was monitored from the day of the NHC. As the storm moved north- northwest, he organized clearly. On May 17, wind shear began to weaken the low pressure area, but the system remained. As of May 20, the storm intensified rapidly. Therefore, the NHC reported on May 21 that the system was classified as Tropical Depression Two -E. The next day, the system organized into a tropical storm and was named Bud, as it drifted west. At this time, Bud had wind speeds of 65 km / h and was a weak tropical storm. Bud held this intensity for a day. Because on May 23 launched buds rapidly intensifying into a Category 3 hurricane. First, however, Bud intensified in the afternoon of May 23 in a strong tropical storm with wind speeds of 110 km / h The next morning Bud continued its intensification continued, so that the storm only to a category 1 hurricane, and later to a Category 2 hurricane reinforced. Later on May 24, Bud turned toward the northeast and began to the west coast of Mexico to approach. At the approach was expected that Bud will weaken again. But exactly the opposite happened and Bud strengthened in Category 3 hurricane with winds of 185 km / h and an air pressure of 961 hPa Bud was able to keep this status for several hours while its outer rain bands reached the west coast of Mexico. Early on 25 May, Bud weakened before reaching the coast of the mainland from a Category 2 hurricane. The storm weakened rapidly further, as he slowly moved towards the mainland, and Bud quickly lost much of its convection. During the afternoon of May 25 Bud weakened to a strong tropical storm and went on Jalisco, Mexico on land. Early on 26 May, Bud degenerated into a remnant low.

Hurricane Carlotta

In the eastern Pacific, a tropical wave in the morning of June 14 quickly became a tropical depression three -E. On the same day, the National Hurricane Center Three -E upgraded to a tropical storm and named him Carlotta. Initially Carlotta had wind speeds of 75 km / h and a minimum air pressure of 1000 hPa but missed to warmer waters as the storm itself Carlotta intensified rapidly and on 15 June at a strong tropical storm with wind speeds of 110 km / h and a minimum pressure of 990 hPa Later that day, Carlotta was only a Category 1 hurricane, then to a Category 2 hurricane. Before Carlotta on the evening of June 15, makes landfall on Puerto Escondido, Mexico, the storm weakens to a Category 1 hurricane. Overland to Carlotta weakens on June 16 on quickly from a tropical storm, and then finally to a tropical depression. On the night of June 17 Carlotta degenerated into a remnant low.

In conjunction with Carlotta floods and landslides were reported. It also three fatalities were reported.

Hurricane Daniel

Early on July 2, the National Hurricane Center began with the observation of a zone disturbed weather that was located about 765 km south-southeast of Acapulco. Over the next 24 hours, the fault always better organized so early a Tropical Cyclone Formation Alert was proclaimed on July 3. On the morning of July 4, the system had Genung organization to be classified as Tropical Depression Four -E. The next day was from the tropical depression, a tropical storm, which was given the name Daniel. After Daniel came across an area with good conditions for further development and stayed two days in this area, the storm reached hurricane status. Early on July 8, Daniel strengthened rapidly on and was now on a Category 2 hurricane. Later that day, Daniel reached its peak as a Category 3 hurricane with winds of 185 km / h and an air pressure of 961 hPa, although Daniel, already tugging over cooler waters. However, the status as a serious hurricane could keep Daniel only briefly, because already six hours later his eye appeared less well defined and the storm weakened to a Category 2 hurricane from. During the July 9 Daniel was graded to a category 1 hurricane due to unfavorable conditions. Early on July 10, Daniel puts his slowdown continued, as he always pulled over cooler water. In this case, the size of the storm was low. The next day, Daniel's circulation center moderate vertical wind shear was suspended at this time Daniel was already only a minimal tropical storm with wind speeds of just 65 km / h Later on July 11, Daniel weakened further into a tropical depression and degenerated to south-southeast of Hawaii into a remnant low. The remains of Daniel stayed for almost a week and had made ​​minimal impact on Hawaii.

Hurricane Emilia

A small but well-organized area of disturbed weather was organized enough to be classified on July 7, as Tropical Depression Five -E. At this time the system was 800 km south-southwest of Acapulco, Mexico. Later that day, the low pressure area had gained enough strength to be, classified as a tropical storm, which was given the name Emilia, the fifth named the season. Early on July 9, Emilia reached hurricane status and began to increase rapidly, which only was made possible by the withdrawing westward Hurricane Daniel now no longer blocked the eastern outflow channel. This has severely affected the development of Emilia. Early on the 10th of July, Emilia peaked as Category 4 hurricane with top speeds of 220 km / h and a minimum air pressure of 945 hPa After its peak Emilia began between a strong Category 3 hurricane and a weaker Category 2 hurricane to fluctuate. Although the storm has already garnered over cool waters, Emilia was their intensity to be maintained because of their annular structure. Late on July 12, but Emilia's eye was no longer visible on the satellite images, as the storm had weakened to a Category 1 hurricane. Early the next morning, it was observed that Emilia same way as Daniel just moved a little further north, so that the storm weakened to a tropical storm due to the poor conditions in the area. This status is stopped Emilia only briefly, as they degenerated because of the very cold surface temperatures on July 15, an extratropical remnant low. On 17 July, the remnant low of Emilia brought minimal impact to Hawaii, as it vorbeizog south there.

Emilia took a very similar path to Daniel a few days earlier.

Hurricane Fabio

Early on July 12, won a well-organized area of ​​low pressure enough strength to be classified on the same day south of Mexico as Tropical Depression Six -E. A few hours later, the organization of the low pressure system was so good that it became Tropical Storm Fabio increased, the sixth named storm of the season. During the afternoon hours of July 13 was reinforced Fabio in a Category 1 hurricane with winds of 130 km / h On the night of July 14 Fabio continued his rapid intensification continued, and was henceforth a strong Category 1 hurricane with winds of around 150 km / h and a minimum air pressure of 979 hPa The storm kept this intensity for a while before he in the afternoon of July 14 rapidly and unexpectedly into a Category 2 hurricane with a well- defined eye increased. After 24 hours, however, Fabio met a field of dry air and cooler waters so he initially weakened to a Category 1 hurricane, and later to a tropical storm. In the course of July 17 Fabio weakened off the coast of central Baja California from without convection to a tropical depression. On 18 July, Fabio degenerated into an extratropical remnant low. The remains of Fabio went on July 19 via Southern California on land and then moved over Nevada until they were absorbed on 20 July, Oregon by a außertropischem low.

Hurricane Gilma

On August 5, the NHC began with the monitoring of a zone disturbed weather on the coast of Mexico. Gradually, the system began to organize and reinforced on August 7 in the Tropical Depression Seven -E. Six hours later, the National Hurricane Center classified the high- low pressure area to a tropical storm, which was given the name Gilma. The next day Gilma began to organize strong and was only one day after its formation into a hurricane. After Gilma moved into cooler waters on 9 August, the hurricane downgraded the National Hurricane Center to a tropical storm down. At this time Gilma had already lost almost their entire convection and degenerated on August 11 an extratropical remnant low.

Tropical Storm Hector

The Tropical Depression Eight -E was created on August 11, using the remnants of Hurricane Ernesto. The system is even stronger on the same evening in a tropical storm and was named Hector. Until August 14, Hector held this status, reaching wind speeds of 85 km / h and a minimum air pressure of about 995 hPa On August 15, the storm struck, however, on an area of ​​cooler waters and strong wind shear and Hector weakened to a tropical low pressure area off. A day later, Hector degenerated into a remnant low.

Hurricane Ileana

The Tropical Depression Nine -E was created on the evening of 27 August. On the night of the following day, the National Hurricane Center upgraded the low pressure area to a tropical storm and named this Ileana. Due to favorable conditions in the days that followed the storm on August 29, could strengthen into a hurricane. After Ileana reached on the night of August 31, culminating with continuous wind speeds of 140 km / h and a minimum air pressure of 978 hPa, she moved on 1 September in cooler waters and began quickly into a tropical storm to weaken. On 2 September, Ileana, which was now only a tropical depression degenerated into a remnant low.

Tropical Storm John

On the evening of September 2 was formed about 480 km south- southwest of Baja California, the Tropical Depression Ten -E. The following day, the low pressure area formed on a weak circulation and weak convection what the National Hurricane Center prompting, it hochzustufen in Tropical Storm John. John reached on this day wind speeds of 75 km / h and a minimum air pressure of 1000 hPa, which corresponds to a weak tropical storm. Due to strong wind shear and cooler waters to the west of Baja California, John could no longer continue to develop and weakened the evening of 3 September in a tropical depression off. On 4 September, John degenerated into an extratropical remnant low.

Tropical Storm Kristy

Early on the 9th of September, a few hundred miles of the Gulf of Tehuantepec south developed a weak area of low air pressure and began heading west - northwest. Due warm waters and low wind shear, the system was more organized and the NHC gave an average opportunity for the emergence of a tropical low pressure area. In the evening hours of September 11 the system from the NHC got a high chance and was on the following morning to a tropical depression eleven -E. Only 6 hours after training it strengthened into a tropical storm, which was given the name Kristy. The storm was persistent and kept his intensity 5 days, although the conditions were pretty bad. On September 16, Kristy has been downgraded to a tropical depression and degenerate on the following day an extratropical remnant low.

Hurricane Lane

Lane originated from an area of low pressure air to the west was formed on 13 September from Tropical Storm Kristy. First, the NHC was only a poor chance for farther development of the disorder, as it was too close to Kristy and it was expected that it interacts with the storm. The following day, the system was moving toward the west, and showed no interaction with Kristy, which is why it has been updated on September 15 for Tropical Depression Twelve -E. The depression could still organize as far, so it was promoted on the night of September 16 a tropical storm Lane on the same day. Initially it was believed that Lane himself was only a tropical storm. But this changed on the morning of September 17, when Lane was a clear eye, and was upgraded to a hurricane. This status could hold 30 hours before it weakened in the afternoon of September 18, back into a tropical storm of the hurricane.

Hurricane Miriam

On 21 September, an area of low pressure air had as far as organized, so it was classified on the next day as a tropical depression Thirteen -E. In the early morning of 22 September, the low pressure area was always more convection and increasing circulation, so it was the same day the tropical storm Miriam later. First, Miriam could not develop as in a tropical storm because of poor conditions. But on the evening of September 23 started Miriam rapid intensification and increased in only 18 hours from a tropical storm into a major Category 3 hurricane with winds of 195 km / h and a minimum air pressure of about 959 hPa After Miriam's peak the afternoon and evening of 24 September met the hurricane on September 25 to an area worse conditions, so that Miriam rapidly weakened and on the evening of 25 September was only a Category 1 hurricane with winds of 140 km / hr. Miriam continued its decline also continued on September 26 and moved directly into the zone west of Baja California. There, the hurricane weakened to a tropical storm on the same day. During the September 27 Miriam continued to lose strength and degenerate on the night of 28th September in an extratropical remnant low. In the next few days the remnant low Miriam changed its direction of pull to the east and moved across Baja California. On 1 October, the remnant low over Texas arrived and was still there weaker. On October 3, the remnants of the system by a monsoon trough from the south were absorbed.

Tropical Storm Norman

Early on September 25, an area of low pressure air began to watch, which was located a few hundred miles south of Acapulco, Mexico, the National Hurricane Center. Over the next two days, the area was getting better organized, so it was classified as a tropical storm Norman on September 28 at 15:00 UTC clock. At this time, Norman was 135 km east of Cabo San Lucas, Mexico. Norman slowed down when he reached the coast of Sinaloa and weakened early on 29 September at a tropical depression off. The depression comes on the same day over Sinaloa ashore and quickly reached the Gulf of California. At noon on 29 September to Norman convection had so far resolved so that it degenerated into an extratropical remnant low in the late afternoon of the same day. Early on 30 September, the remnant low of Norman was completely dissolved.

Tropical Storm Olivia

On October 2, formed off the coast of Mexico an area of low pressure air, which at first was very disorganized in the course of the following days. On October 5, the area did not begin very rapidly to organize than it already was located far away from the coast. On the afternoon of October 6, it was so well organized, so it was classified as a tropical depression Fifteen -E. Increased only 6 hours after the formation of the low-pressure area into a tropical storm, which was given the name Olivia and quickly developed. Early in the morning of October 7, Olivia reached its peak with winds of 95 km / h and a minimum air pressure of 998 hPa in the course of the day the storm began to keep this status constant, before settling on the morning of October 8 a little weakened. After Olivia had slowed down a little, she was always disorganized and weakened the morning of the 9th of October in a tropical depression off. Shortly thereafter, Olivia degenerated into a remnant low. Early on October 11, the remnant low of Olivia was completely dissolved.

Hurricane Paul

Early on October 10, an area of ​​showers and thunderstorms several hundred miles west of Central America began the NHC observed. As the system moved towards the west, it could develop slowly. On October 13, it had as much organized so that it formed a weak circulation and was surrounded only by convection. This prompted the NHC to upgrade the area into a tropical storm, which was given the name Paul. At this time, the still weak Paul was 1065 km south-southwest of Baja California. Along a subtropical ridge over Central Mexico Paul was forced to move west and then hit on an area with only slight wind shear and high sea surface temperature. Because of these very good conditions, Paul began a rapid intensification and increased on the morning of October 15 in a Category 1 hurricane. Just 12 hours later, Paul formed a well - visible eye and reached at this time wind speeds of 195 km / h, which corresponds to a major Category 3 hurricane. This culminated Paul already, as he turned off to his western direction northeast towards Baja California. A combination of high wind shear and dry air was Paul weaken rapidly on October 16, before he reached the land as a Category 1 hurricane in the evening. When Paul the coast pulled along on October 17th and weakened into a tropical storm, the storm made ​​two excursions ashore, the first on the southwest coast of Baja California as a Category 1 hurricane and the second near the city of Bahía Asunción in the district of Mulege, in the state of Baja California Sur, Mexico as a tropical storm. After the country gears, the NHC Paul downgraded to a tropical depression. A little later, Paul degenerated into a remnant low extratropical without any convection and without circulation.

Tropical Storm Rosa

On October 26, the NHC an area of low pressure air began 1000 km south-southwest of Manzanillo, Mexico to observe. This could be the next day and got slowly to organize on that day a medium chance of development of a tropical cyclone. This status could keep the area in the next few days and received on the evening of 29 October, even a high chance, so it was classified as a tropical depression Seventeen -E on 30 October at 10:00 UTC clock. Increased only 5 hours after the update, the low pressure area in the tropical storm pink. The storm reached its peak on November 1 at 03:00 UTC clock with wind speeds of 85 km / h and a minimum air pressure of 1001 hPa, which corresponds to a moderate tropical storm. After the peak, however, Rosa weakened further and was on 3 November at 21:00 UTC clock only a tropical depression. That same evening, Rosa degenerated into a remnant low.
