The
2006 Atlantic hurricane season was a fairly inactive
Atlantic hurricane season compared to
the 2005 season. The season officially started on
June 1,
2006, and officially ended on
November 30,
2006, dates which by convention delimit the period of each year when the majority of tropical cyclones form in the
Atlantic basin. One system, Tropical Storm Zeta from the
2005 season, continued through early January, only the second time on record that had happened. 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 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 during October, for the first time since the
1994 season. While forecasts predicted that the 2006 season would be very active, a rapidly forming
El Niño event in 2006, 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 around Bermuda contributed to a slow season. (
