2006 Atlantic hurricane season

The hurricane season officially began on June 1, 2006 and ended on 30 November. Within this period, make the most tropical storms, since only at this time suitable conditions, such as a warm ocean, moist air and little wind shear, exist to allow the formation of tropical cyclones.

During the Atlantic hurricane season of 2006, there were significantly fewer hurricanes than was initially forecast at the beginning of the year. There was no hurricane force 4 or 5, a total of five storms which reached the strength of a hurricane, two strong and three storms reached the mainland. The highest measured wind speed on the mainland was 72 km / h ( Alberto at Panhandle near Adams Beach on 13 June). In October and November 2006, no longer a hurricane formed. Thus, it was an average season (1950-2000 average: 9.6 total storms, of which 5.9 hurricanes and 2.3 strong hurricanes ).

Storms

Tropical Storm Alberto

On June 10, organized off the coast of Belize, the first Tropical Depression of the season. Despite vertical wind shear, the low pressure area on the morning of June 11th to Tropical Storm Alberto reinforced. But then finally the beginning rather disorganized and weak tropical storm could be on the Loop Current, a warm current in the Gulf of Mexico, to a strong tropical storm with wind speeds of up to 115 km / h, so just below hurricane strength, intensify. About the shallow waters off the Florida coast, he weakened, however, and went on 13 June, 85 km south-east of Tallahassee on land where it caused lighter damage and flooding. On 14 June, the now demoted to a tropical depression Alberto lost all its tropical characteristics and became extratropisch.

Untitled Tropical Storm

In the follow-up analysis, an initially undetected tropical storm was discovered, which developed at the Gulf Stream, south of Nantucket, from an extra- tropical depression on July 17. The system was briefly a tropical storm before it on July 18, southeast of Nova Scotia, degenerated into a remnant low. It brought wind and rain over parts of Atlantic Canada, without causing damage.

Tropical Storm Beryl

In mid-July, a cold front moved towards the east coast of the U.S. and broke up, which formed two low-pressure areas. The more northerly of the two was able to quickly organize, and was initially not recognized until the post-analysis as a tropical storm, the more southerly of the two barely moved and stayed off the coast of North Carolina, without being really organized. On 18 July, however, it began to organize themselves quickly and was then incremented for the second tropical depression of the season. The low moved slowly northward and intensified by the warm Gulf Stream to Tropical Storm Beryl. Beryl went on July 21 in Nantucket, Massachusetts on land where they wreaked only slight damage.

Tropical Storm Chris

The end of July formed in front of the coast of Africa a vigorous tropical wave and slowly drifted westward. You could develop extremely slowly due to dry air but. Nevertheless, she was able to organize on July 31, enough to be classified a tropical depression. The depression strengthened on 1 August to a tropical storm and then moved west- northwestward towards the Lesser Antilles. While Chris was moving westward, it was believed at first that he could strengthen into a hurricane and thus threaten the Florida coast. But Chris got into an area with high wind shear and dissipated on August 5 in a broad area of ​​low pressure on.

Tropical Storm Debby

A system from the coast of Africa, which was observed by the NHC for days on possible development, was incremented on August 21, a tropical depression. It immediately became a tropical storm warning issued for the Cape Verdi Islands, since it was feared that the system could pull south over the archipelago. However, the system could not strengthen to tropical storm strength and, therefore, the warnings have been lifted.

The low-pressure system could strengthen into a tropical storm on August 22 and was named Debby. At first it was believed that it could strengthen into a hurricane continued, but high wind shear and dry air prevented this and the system weakened on August 26 back to a tropical depression off. On the same day it lost all its tropical characteristics and was extratropisch.

Hurricane Ernesto

On August 24, a reconnaissance aircraft confirmed that a tropical wave that passed through the Windward Islands, had developed a closed circulation, after which it was incremented to a tropical depression. On August 25, discovered a further reconnaissance, that the system had reached the wind speed of a tropical storm, and the low pressure area was named Ernesto. On August 27, Ernesto reached hurricane strength when he was close to the southern tip of Haiti, however, the high mountains interfered with the circulation of the storm and Ernesto was downgraded on the same day back to a tropical storm.

On August 28, the storm went to the Guantánamo Bay on land. Previously, it was predicted that the storm could become a major hurricane in the Gulf of Mexico, just during the commemoration for the victims of Hurricane Katrina. But the storm was moving much further east than expected, which brought the Gulf out of danger. On August 29, he went as a tropical storm on the southern tip of Florida on land and weakened into a tropical depression off. However, the storm could intensify quickly, as he moved back over water. On August 31, he went with almost hurricane strength in North Carolina on land and was the next day extratropisch.

The storm killed at least eight people, three in Haiti and five in the United States.

Hurricane Florence

On September 3, formed between Africa and the Lesser Antilles, a tropical depression. It strengthened initially slow, but enough to September 5 to be due to the wind shear for tropical storm Florence. As tropical storm Florence expanded greatly; tropical storm strength was achieved up to 650 km from the center. With its disorganized structure and multiple centers Florence remained for several days, a weak tropical storm, even after the external conditions had improved for a reinforcement. On the morning of September 10 reached hurricane strength Florence and soon near Bermuda his greatest strength as a Category 1 hurricane and was on September 12, while still a hurricane, extratropisch.

Hurricane Gordon

While Florence withdrew to a low pressure area northeast of the Lesser Antilles organized. It developed a closed circulation and was declared on 10 September at a Tropical Depression. After it is increasingly intensified, it became a tropical storm on 11 September and on 12 September the hurricane. Gordon reached the status of a category 2 hurricane on September 13 and has been promoted in the same night in category 3, making him the first major hurricane of the season.

To September 16 around his position was for some time almost unchanged approximately 1600 km to the east of Bermuda, where it weakened to scarce hurricane strength. While he subsequently accelerated eastward, he strengthened himself, however, again to Category 2 on September 19 warnings were issued for the Azores, because the predicted path led through the center of the archipelago. On September 20, he reached the eastern Azores as Hurricane level 1

Hurricane Helene

On September 11, a tropical wave left the coast of West Africa. The shaft organized very quickly and was able to develop on 12 September in a tropical depression. The system could intensify steadily and was classified on 13 September for the tropical storm Helene. The system continued, under good weather conditions, the intensification trend continued and strengthened to intensify on September 16 in a hurricane, around a day later, the second major hurricane (Category 3 ) of the season. Helene moved generally west in northwestern direction before wegsteuerte to the northwest addition to the high seas. Helene caused high water waves in Bermuda, but at no time threatened the country. On September 24, the system was extratropisch.

Hurricane Isaac

A low pressure system in the central Atlantic initially produced some days active thunderstorm and was up graded on 27 September for the ninth tropical depression of the season. The depression intensified on September 28, about 1300 km east-southeast of Bermuda to a tropical storm. On 30 September, Isaac intensified into a hurricane and moved about 450 km to the east of Bermuda by to then be heading north on Newfoundland. On 2 October was spent on the peninsula of Avalon storm warning. Isaac drew the same afternoon over about 45 km of Cape Race and brought there and rain squalls to 96 km / h to.

Placement after Cyclone Accumulated Energy (ACE )

The adjacent table shows the ACE for each storm this year. The ACE describes the energy of a tropical storm by the strength of a storm is multiplied by the length of time that is long-lasting storms and severe storms have a high ACE value.
