Instead, it turned out to be a below average season, as activity was slowed by a rapidly forming moderate El Niño event, the presence of the Saharan Air Layer over the tropical Atlantic, and the steady presence of a robust secondary high-pressure area to the Azores High centered on Bermuda. There were no tropical cyclones after October 2.November 17, 2006 Summary of 2006 Atlantic Tropical Cyclone Activity and Verification of Authors' Seasonal and Monthly Forecasts Colorado State University November 17, 2006 http://hurricane.atmos.colostate.edu/Forecasts/2006/nov2006/ Klotzbach Philip J.

Hurricane Ernesto caused heavy rainfall in Haiti, and directly killed at least seven in Haiti and the United States. Four hurricanes formed after Ernesto, including the strongest storms of the season, Hurricanes Helene and Gordon. In total, the season was responsible for 14 deaths and $500 million in damage. The calendar year 2006 also saw Tropical Storm Zeta, which arose in December 2005 and persisted until early January, only the second such event on record. The storm is considered a part of the 2005 season, as it developed in that calendar year. Seasonal forecasts Forecasts of hurricane activity are issued before each hurricane season by Philip J. Klotzbach, Dr. William M. Gray, and their associates at Colorado State University; and separately by NOAA forecasters. Klotzbach's team (formerly led by Gray) has defined the average number of storms per season (1950–2000) as 9.6 tropical storms, 5.9 hurricanes, and 2.3 major hurricanes (storms exceeding Category 3 strength in the Saffir–Simpson scale). A normal season, as defined by NOAA, has 6–14 named storms, with 4–8 of those reaching hurricane strength, and 1–3 major hurricanes.Klotzbach, Philip J. Gray, William M.

As in the 2005 season, the team predicted it was highly probable that at least one major hurricane would directly impact the United States. The forecast suggested an 81% probability that at least one major hurricane would strike the U.S. mainland, a 64% chance of at least one major hurricane striking the East Coast of the United States (including the Florida peninsula), and a 47% chance of at least one major hurricane striking the Gulf Coast of the United States from the Florida Panhandle westward. The team also predicted that the potential for major hurricane activity in the Caribbean was above average. A few months later, on April 4, 2006, CSU issued another forecast confirming its December predictions.Klotzbach, Philip J. Gray, William M.

The prediction was for 13–16 named storms, 8–10 of those becoming hurricanes, and 4–6 becoming major hurricanes. On May 31, 2006, Klotzbach's team released its final pre-season forecast for 2006, confirming its earlier prediction.Klotzbach, Philip J. Gray, William M.

Compared to the devastating 2005 Atlantic hurricane season, 2006 was not severe in terms of deaths and damage. Three tropical storms made landfall in the United States. The first of them, Tropical Storm Alberto, made landfall in Florida with winds of 50 mph km/h on, causing flooding and light damage. Tropical Storm Beryl made landfall on Nantucket, but left little impact. The third and more significant storm was Hurricane Ernesto, which killed two people in Virginia and two in Florida, as well as causing $500 million in damage (2006 USD).Knabb, Richard D. Mainelli, Michelle Hurricane Ernesto Tropical Cyclone Report December 15, 2006 National Hurricane Center January 27, 2008 AL062006_Ernesto PDF During the season, only one tropical cyclone in the Atlantic – Alberto – affected Mexico. Canada was affected by several tropical cyclones during 2006, including Alberto, the unnamed storm, Beryl, Florence, and Isaac. On June 20, an upper-level disturbance formed east of the Bahamas and moved westward across the islands. Between June 24 and 26, areas of convection developed occasionally, and a low-level disturbance formed. The system turned northward and upon reaching the Gulf Stream on June 27, it began to mature. It made landfall near Morehead City, North Carolina and moved northeastward along the U.S. East Coast. The storm contributed to severe and deadly flooding in the Mid-Atlantic states. While the NHC did not operationally classify it, data from reconnaissance aircraft, NEXRAD weather radar, and surface observations suggest it may have met the criteria for a tropical cyclone.138 1 Gruskin, Zachary Monthly Weather Review American Meteorological Society 265–278 January 2010 Structure and Evolution of a Possible U.S. Landfalling Tropical Storm in 2006 10.1175/2009MWR3000.1 2010MWRv..138..265G free left|thumb|A graph showing averages and statistics for Atlantic hurricane seasons The National Hurricane Center's pre-season activity outlook predicted 13–16 named storms, 8–10 hurricanes and 4–6 major hurricanes. They also predicted a high risk of at least one major hurricane strike to the Southeastern United States. In the event, only ten storms formed during the season, the lowest number since the 1997 season, when there were seven. Five of the ten storms developed into hurricanes— the lowest number since 2002– only two attained major hurricane status, tying with 2002 for the fewest since 1997. Only one named storm was observed during October, the lowest number since 1994, when none were seen during that month. Additionally, only three named storms made landfall in the United States, the fewest since 2001. Because of several factors, including a rapidly forming El Niño event, the Saharan Air Layer over the tropical Atlantic and the presence of a high-pressure area to the Azores High situated near Bermuda, it contributed to a below average season.2006 NOAA Predicts Very Active 2006 North Atlantic Hurricane Season National Oceanic and Atmospheric Administration May 22, 2006 http://www.noaanews.noaa.gov/stories2006/s2634.htm https://web.archive.org/web/20060612004343/http://www.noaanews.noaa.gov/stories2006/s2634.htm 12 June 2006 live Also, sea surface temperatures in the western Atlantic were just at or slightly below average.

It dropped light rainfall in Mexico, with a 24-hour total peaking at 4 in mm in Peto, Yucatán.Hernández Unzón, Alberto 2006 Resumen de la Tormenta Tropical "Alberto" del Océano Atlántico Servicio Meteorológico Nacional May 11, 2007 http://smn.cna.gob.mx/ciclones/tempo2006/atlantico/alberto/alberto.pdf https://web.archive.org/web/20070102114330/http://smn.cna.gob.mx/ciclones/tempo2006/atlantico/alberto/alberto.pdf January 2, 2007 Southwesterly vertical wind shear initially prevented significant development, but as it moved closer to Florida, the depression strengthened into a tropical storm on 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 km/h on, just shy of hurricane strength. Subsequent weakening occurred as it moved over the cooler waters of the continental shelf, and Alberto made landfall near Adams Beach, Florida, on June 14 with winds of about 45 mph km/h on. Losing its tropical characteristics, Alberto moved northeastward and produced heavy rainfall in South Carolina and North Carolina. The remnants tracked off the U.S. East Coast and transitioned into a powerful extratropical storm which affected Nova Scotia with high winds, heavy rain, and rough surf, leaving four fisherman missing offshore.Avila, Lixion A.

The system separated itself from the dissipating front later that day while moving northeastward over warm waters. Convection developed near the center, and the system transitioned into a tropical depression early on July 17, about 240 mi km southeast of Nantucket, Massachusetts. Accelerating northeastward, the depression intensified into a tropical storm six hours later. Banding features became prominent, and after continued strengthening, the storm attained peak winds of 50 mph km/h on late on July 17, while located about 245 mi km south of Halifax, Nova Scotia. Shortly thereafter, the storm encountered much cooler water temperatures after leaving the Gulf Stream. The storm quickly weakened as the convection rapidly diminished, and on July 18, degenerated into a non-convective remnant low. The remnants crossed Newfoundland, before turning to the east-northeast and dissipating on July 19. The storm greatly weakened prior to moving across Newfoundland, and as a result, its impact was minimal. Operationally, the storm was considered as a non-tropical gale, connected to a cold front. However, a post-season analysis provided enough evidence of tropical characteristics, indicating no frontal features and no cold air intrusion at the time of peak winds. Observations analyzed the storm as having a symmetric warm core, whereas in real time it was considered subtropical. The National Hurricane Center officially re-classified the system as an unnamed tropical storm on December 15, 2006.

Later that day, the depression developed organized rainbands over the eastern periphery of the circulation, and as a result, the NHC upgraded it to Tropical Storm Beryl. The nascent storm moved generally northward at first along the western periphery of a subtropical ridge, parallel to the East Coast of the United States. With low wind shear and favorable outflow, Beryl intensified to reach a peak intensity of 60 mph km/h on early on July 20.

The storm was forecast to strengthen further and become a hurricane as it moved into the Bahamas. However, Chris began to be affected by wind shear and became disorganized. The storm weakened to a tropical depression on August 4, and dissipated as it approached the Cuban coast on August 5.Stewart, Stacy R.

The wave progressed westward and reached the Western Atlantic, spawning a tropical depression on August 24 near the Windward Islands. It moved west-northwestward through the Caribbean Sea and intensified into Tropical Storm Ernesto on August 25. The storm briefly attained hurricane status on August 27 to the southwest of Haiti, before land interaction caused weakening. Ernesto made landfall near Guantánamo Bay, Cuba, early in the morning on August 28 as a tropical storm. 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. Ernesto retained 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. Ernesto transitioned into an extratropical cyclone over Virginia on September 1, which ultimately dissipated over Quebec on September 4. Early in its duration, Ernesto killed five people in Haiti from rainfall. Later, two people died in Florida in traffic accidents due to slick roads. Damage was heaviest in Virginia, where heavy rains left severe flooding. Damage in the United States was estimated at $500 million (2006 USD). Hurricane Florence Atl Florence 2006-09-10 1730Z.jpg Florence 2006 path.png September 3 September 12 80 974 Hurricane Florence (2006) Hurricane Florence originated on September 3 from the complex merging of two tropical waves, creating one large low-pressure area. The disturbance moved westward and became a tropical depression in the open waters of the Atlantic. On September 5, it organized further and was upgraded into Tropical Storm Florence. 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. Florence tracked west-northwest and intensified into a hurricane on September 10 while south of Bermuda. The storm passed just to the east of Bermuda as a Category 1 hurricane on the Saffir–Simpson scale as it reached its peak intensity of 90 mph km/h on. It moved north before losing its tropical characteristics and passing over the Canadian Maritimes as a strong extratropical storm.Beven, Jack Hurricane Florence Tropical Cyclone Report January 4, 2007 National Hurricane Center January 27, 2008 AL072006_Florence PDF Large swells, rip tide, and undertow were reported on Bermuda, the Leeward Islands, the Virgin Islands, and Hispaniola.Associated Press CNN Bermuda braces as Florence becomes hurricane September 10, 2006 http://www.cnn.com/2006/WEATHER/09/10/bermuda.tropical.ap/index.html https://web.archive.org/web/20060926071243/http://www.cnn.com/2006/WEATHER/09/10/bermuda.tropical.ap/index.html September 26, 2006 Florence affected Bermuda with wind gusts up to 115 mph km/h on and heavy rain which left 23,000 houses without electricity.

The wave tracked westward across the Atlantic for several days until it reached an area of relaxed wind shear and its associated low-pressure area organized into a tropical depression. It moved east-northeast and was upgraded to Tropical Storm Gordon on September 11, while located over the open waters of the Atlantic. Gordon turned north, and became a hurricane on September 13. It intensified to Category 3 status on the Saffir–Simpson scale and reached its peak intensity of 120 mph km/h on on September 14. Tracking northward, it began to lose tropical characteristics. On September 20, the system affected Britain with high winds and heavy rain as an extratropical cyclone.Blake, Eric S.

The convection increased and organized further, leading to the development of a tropical depression on September 12, located 270 mi (370 km) south-southeast of the Cape Verde Islands. While passing south of the islands, the depression struggled to intensify due to easterly wind shear and the cyclone's large size. Improved rainbands developed over the northern periphery, signaling that the depression intensified into Tropical Storm Helene on September 14.Brown, Daniel P. Hurricane Helene Tropical Cyclone Report November 15, 2006 National Hurricane Center January 27, 2008 AL092006_Helene PDF A day later, as wind shear decreased, Helene began intensifying, reaching hurricane intensity on September 16, as it developed a ragged eye in the center of the convection.September 15, 2006 Tropical Storm Helene Discussion #13 National Hurricane Center 2006-11-24 http://www.nhc.noaa.gov/archive/2006/al08/al082006.discus.013.shtml?

Helene also turned more northward and slowed in the central Atlantic, which was in response to a weakness in the subtropical ridge farther north created by Gordon to the north. Early on September 18, Helene peaked as a Category 3 hurricane with winds of 120 mph km/h on. At the time of peak intensity, Helene and Gordon were at roughly the same longitude in the open ocean, although the latter moved eastward. This caused a ridge to move southward, forcing Helene westward. Helene weakened slightly due to a lengthy eyewall replacement cycle and an elongated cloud pattern.September 19, 2006 Hurricane Helene Discussion #31 National Hurricane Center 2006-11-24 http://www.nhc.noaa.gov/archive/2006/al08/al082006.discus.031.shtml?

Helene remained a warm-core cyclone until September 24, when it transitioned into an extratropical cyclone northwest of the Azores. Continuing northeast, the cyclone passed near Iceland on September 27. Later that day, the remnants of Helene merged with another larger extratropical cyclone north of the British Isles.

Hurricane Isaac Atl Isaac 2006-09-30 1710Z.jpg Isaac 2006 path.png September 27 October 2 75 985 A tropical wave exited the west coast of Africa on September 18. For several days, the system moved across the Atlantic, producing occasional pulses of convection. Wind shear limited development, until relaxing enough for a tropical depression to develop on September 27, located about 930 mi km on southeast of Bermuda. On the next day, the depression intensified into Tropical Storm Isaac. Initially, the storm was tracking towards the northwest, between another low pressure system to its west and a low- to mid-level ridge to its east. Throughout the day, thunderstorm activity remained unstable, possibly as a result of cooler waters churned up by previous storms. In addition, mid- to upper-level dry air had become entrained into the circulation, and the storm contained some subtropical characteristics with a baroclinic-type cloud pattern. Slow intensification continued, and ISaac attained hurricane status on September 30. Early the next day, Isaac reached peak winds of 85 mph (140 km/h).Mainelli, Michelle Hurricane Isaac Tropical Cyclone Report November 16, 2006 National Hurricane Center January 26, 2008 AL102006_Isaac PDF Around that time, a ragged eye feature appeared on satellite imagery.Lindsea/Stewart Hurricane Isaac Discussion Number 15 October 1, 2006 National Hurricane Center 2009-06-20 http://www.nhc.noaa.gov/archive/2006/al09/al092006.discus.015.shtml? After reaching peak intensity, Isaac curved the periphery of the subtropical ridge, turning to the north-northeast. Stronger wind shear and cooler waters caused Isaac to weaken to a tropical storm on October 2. That day, Isaac passed about 40 mi km on to the southeast of the Avalon Peninsula of Newfoundland. At Cape Race, sustained winds peaked at 46 mph km/h on, with gusts of up to 60 mph km/h on. Shortly after passing the island, Isaac transitioned into an extratropical cyclone, and on October 3 the remnants merged with a larger extratropical storm.
