List of storms in the 2006 Atlantic hurricane season

The list of storms in the 2006 Atlantic hurricane season is a complete list of all tropical cyclones of the 2006 Atlantic hurricane season in the Atlantic Ocean basin. The season started on June 1, 2006, and officially ended on November 30, 2006. These dates conventionally delimit the period of each year when most tropical cylones form in the Atlantic basin.

Tropical Storm Alberto was responsible for two indirect deaths when it made landfall in Florida. Hurricane Ernesto caused heavy rainfall in Haiti, and directly killed at least seven people in Haiti and the United States. Four more hurricanes formed after Ernesto, including the strongest storms of the season, Hurricanes Helene and Gordon. No tropical cyclones formed in the month of October, the first time this had happened since the 1994 season.cite web|author=National Hurricane Center|date=2006-11-01|accessdate=2006-11-01|url=http://www.nhc.noaa.gov/archive/2006/tws/MIATWSAT_oct.shtml?|publisher=National Oceanic and Atmospheric Administration|title=Monthly Tropical Weather Summary for October 2006]

Following the intense activity of the 2005 season, forecasts predicted the 2006 season would be very active, though not as active as 2005. However, in 2006, a rapidly forming El Niño event, combined with the pervasive presence of the Saharan Air Layer over the tropical Atlantic and a steady presence of a robust secondary high related to the Azores high centered around Bermuda, contributed to a slow season and all tropical cyclone activity ceasing after October 2.cite web

Tropical Storm Zeta (2005)

Tropical Storm Zeta formed on December 30, 2005 and lasted until January 6, 2006.cite web|author=National Hurricane Center|title=Tropical Cyclone Report: Tropical Storm Zeta|publisher=NOAA|accessdate=May 1|accessyear=2006|format=PDF|url=http://www.nhc.noaa.gov/pdf/TCR-AL312005_Zeta.pdf] Although it spent most of its existence in 2006, it is officially a storm of the 2005 Atlantic hurricane season since it formed during 2005. Zeta joined Hurricane Alice as only the second Atlantic tropical cyclone in recorded history to exist during two different calendar years.cite web|author=National Hurricane Center|title=Tropical Cyclone Report: Tropical Storm Zeta|publisher=NOAA|accessdate=May 1|accessyear=2006|format=PDF|url=http://www.nhc.noaa.gov/pdf/TCR-AL312005_Zeta.pdf]

Track=Alberto 2006 track.pngFormed=June 10
Dissipated=June 14
1-min winds=60
Pressure=995On June 10, an area of disturbed weather associated with a broad low pressure area off the coast of Belize organized over the warm waters of the Caribbean Sea. The low further developed, and became the first tropical depression of the season. Southwesterly vertical wind shear was a constant companion to the system, but as it moved closer to Florida, the depression strengthened into a tropical storm on the morning of June 11. Passing over the warm, deep water of the Loop Current allowed accelerated development, and the cyclone reached its peak winds of 70 mph (115 km/h), just shy of hurricane strength. Subsequent weakening occurred as it moved over the cooler waters of the continental shelf.cite web|author=Lixion Avila & Daniel Brown|year=2006|title=Tropical Storm Alberto Tropical Cyclone Report|publisher=National Hurricane Center|accessdate=2007-05-10|url=http://www.nhc.noaa.gov/pdf/TCR-AL012006_Alberto.pdf|format=PDF]

The large system was slow to weaken, moving across Georgia and the Carolinas before being downgraded to a tropical depression early on June 14. Alberto became an extratropical storm that morning while quickly moving towards the coast. As an extratropical storm, Alberto strengthened rapidly offshore New England and the Canadian Maritimes, becoming an oceanic storm by the afternoon of June 15.cite web|author=National Hurricane Center|title=Tropical Storm Alberto Final Public Advisory #18, 11 a.m. EDT, June 14 2006|publisher=National Oceanic and Atmospheric Administration|accessdate=2006-06-14|url=http://www.nhc.noaa.gov/text/refresh/MIATCPAT1+shtml/] cite web|author=National Hurricane Center|title=Tropical Storm Alberto Coastal Watches/Warnings and 5-Day Cone, 11 a.m. EDT, June 14 2006|publisher=National Oceanic and Atmospheric Administration|accessdate=2006-06-14|url=http://www.nhc.noaa.gov/refresh/graphics_at1+shtml/144546.shtml?5day] Damage in the United States totaled to $420,000 (2006 USD), and one indirect death occurred.

Because steering currents were weak, the most southerly disturbance slowly drifted to the south, and gradually became more organized a few hundred miles east of the North Carolina coast. On the morning of July 18, the low pressure area was designated the second tropical cyclone of the season.

Beryl continued moving to the north until it turned to the northeast on July 20. Beryl paralleled the East Coast of the United States and made landfall on Nantucket island before becoming extratropical southwest of Nova Scotia on July 21. The storm caused high waves along the East Coast of the United States, with 19 feet seas (5.97 m) in the open ocean.

1-min winds=65
Pressure=985At 1900 UTC on August 24, a reconnaissance flight determined that a tropical wave passing through the Windward Islands had developed a closed tropical circulation, and advisories were commenced on Tropical Depression Five. By 5 p.m. EDT (2100 UTC) on August 25, a second flight had found sustained tropical-storm force winds, and the system was named Ernesto. Ernesto became a hurricane on the morning of August 27 just south of Haiti, before it was downgraded back to a tropical storm in the afternoon. The storm caused five deaths in Haiti due to rainfall.Cite web|author=Richard D.

Ernesto made landfall near Guantanamo Bay, Cuba, early in the morning on August 28. At one point the storm was predicted to become a major hurricane in the Gulf of Mexico and threaten parts of the Gulf Coast. However, Ernesto moved much farther east than anticipated, and made landfall as a tropical storm on the southern tip of Florida on August 29. Two people died in Florida in road traffic accidents attributed to the weather conditions, as the cyclone slowly moved northward across the southern half of the peninsula. Ernesto regained tropical storm strength as it crossed Florida and emerged from land near Cape Canaveral, and was just below hurricane strength when it made landfall again in North Carolina on August 31.Cite web|author=Richard D.

Despite the moderate to high wind shear, it strengthened enough to become Tropical Storm Florence on the morning of September 5. After becoming a tropical storm, Florence's wind field began to expand greatly; at one point tropical storm-force winds extended outward up to convert|450|mi|km from the center. With a disorganized structure and multiple circulation centers, Florence remained a weak tropical storm for several days, even after external conditions became favorable for strengthening. Around the evening of September 8 it resolved to a single center and steady strengthening resumed.

On the evening of September 10, it developed a closed circulation and was declared Tropical Depression Seven. It continued to intensify, and strengthened into Tropical Storm Gordon on September 11 and Hurricane Gordon late on September 12. Gordon attained Category 2 status on the evening of September 13, and was further upgraded to Category 3 status that same night, making it the first major hurricane of the season.Cite web|author=Eric Blake|title=Hurricane Gordon Tropical Cyclone Report|year=2006|publisher=National Hurricane Center|accessdate=2008-03-07|url=http://www.nhc.noaa.gov/pdf/TCR-AL072006_Gordon.pdf]

On September 19 hurricane warnings were issued for the Azores, as the predicted path passed through the center of that archipelago. It became extratropical on September 20 after passing through Azorean waters, but the remnants side-swiped north-western Spain and then moved rapidly north towards Ireland and the west of Britain on September 21. By the morning of September 22, it had become absorbed into a large Atlantic low to the west of Ireland.Cite web|author=Eric Blake|title=Hurricane Gordon Tropical Cyclone Report|year=2006|publisher=National Hurricane Center|accessdate=2008-03-07|url=http://www.nhc.noaa.gov/pdf/TCR-AL072006_Gordon.pdf]

Although there were no reports of fatalities from Gordon, when it sideswiped the Azores, it produced high winds and heavy rainfall causing minor damage limited to fallen trees and powerlines. During the extratropical stages of the storm's exsistance, it brought high wind to Spain causing four injuries and leaving 100,000 people without electric power. In Northern Ireland, 126,000 homes were left without power, and one injury occurred. In addition, the strong extratropical storm produced high winds and rain, which affected practice rounds at the Ryder Cup golf tournament in Ireland.cite web|author=BBC news|title=Thousands still without power|year=2006|publisher=|accessdate=2008-01-26|url=http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/5371984.stm]

Pressure=955On September 11, a tropical wave moved off the coast of Africa. It quickly organized, and on September 12 was declared Tropical Depression Eight. It developed broad low pressure system as it passed south of the Cape Verde Islandss. Easterly wind shear initially slowed intensification, although on September 13, convective banding increased over the northern semi-circle. Continuing to organize, it reached tropical storm strength on September 14, becoming a hurricane on September 16. Helene tracked northwestward and slowed down, due to a weakness in the ridge created by Hurricane Gordon. The storm attained major hurricane status on September 17. It moved generally west-northwestward before commencing a northeasterly turn. Large currents from Helene lashed Bermuda. It became fully extratropical on September 24.

Track=Isaac 2006 track.pngFormed=September 27
Dissipated=October 2
1-min winds=75
Pressure=985An area of low pressure in the mid-Atlantic generated active thunderstorms for several days and eventually organized into Tropical Depression Nine on September 27, and a tropical storm by September 28. By that time it was about 810 miles east-southeast of Bermuda. It became a hurricane on September 30, and passed about 280 miles (450 km) east of Bermuda before swinging northwards towards Newfoundland. As it was still a strong tropical storm near the Avalon Peninsula, tropical storm warnings were issued on October 2 due to the potential for high winds. Isaac passed 45 km (30 miles) to the southeast of Cape Race late that afternoon.Cite web|author=Michelle Mainelli|title=Hurricane Isaac Tropical Cyclone Report|year=2006|publisher=National Hurricane Center|accessdate=2008-04-26|url=http://www.nhc.noaa.gov/pdf/TCR-AL092006_Isaac.pdf] The Canadian Hurricane Centre reports that if Isaac had tracked just 50 to 100 km (30 to 60 miles) farther north than it did, the St. John's area would have experienced much higher winds than the peak gust of 54 km/h (34 mph) it received.cite web|author=Canadian Hurricane Center|title=Hurricane Isaac Post-Tropical Storm Information Statement|year=2006|publisher=|accessdate=2008-04-16|url=http://www.atl.ec.gc.ca/weather/hurricane/bulletins/20061003022851.Isaac.txt.en]

At its closest approach to the Avalon Peninsula, Isaac was still tropical, and had maximum sustained winds of convert|50|kn and a minimum central pressure of 993 mbar. Strongest winds on land in Newfoundland were reported at Cape Race, where a maximum gust to 96 km/h (60 mph) with a sustained wind of 74 km/h (46 mph) was recorded. At Cape Pine, a peak wind was reported at 76 km/h (47 mph). However, due to Isaac's small size and fast forward speed, winds were lighter over most of the Avalon Peninsula. Rainfall from Isaac was not reported to be higher than 25 mm (0.98 inches) in most areas due to Isaac's speed and decreasing amount of moisture. The highest measured amount was 26 mm (1.02 inch) at Cape Race, while Cape Pine reported 19 mm (0.75 inches) and St. John's reported less than 10 mm (0.39 inches).
