The 2009 Atlantic hurricane season officially began on June 1st, 2009, and ended on November 30, 2009. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin.
Despite pre-season forecasts of at least average activity, seasonal activity was the least observed since 1997, with only eight named storms forming. Only two of those storms attained hurricane status. This is the lowest amount of hurricanes observed in the Atlantic since 1982. Additionally, this is the first season since 1993 in which only one named storm made landfall in the United States. Finally, when Ana became a tropical storm on August 12, it marked the latest start to an Atlantic hurricane season since 1992.
Many of the storms in the season were short-lived and were not notable. Hurricane Bill was a powerful Cape Verde hurricane that attained Category 4 status in the central Atlantic Ocean during the middle of August. Bill passed about 150 miles to the west of Bermuda, bringing tropical storm force winds and heavy rain, but little else. Bill threatened much of the East Coast of the United States, but ended up recurving and striking Atlantic Canada as a tropical storm. Bill subsequently transitioned into an extratropical cyclone as it raced eastward across the northern Atlantic Ocean, well-embedded within the westerlies. Tropical Storm Claudette, though not terribly notable damage-wise, is at least somewhat notable for being the only storm in the season to make landfall along the United States coastline. Claudette struck the Florida Panhandle as a weak tropical storm, bringing heavy rain and a few tornadoes, but little else.
Hurricane Fred was another powerful Cape Verde hurricane, attaining Category 3 status east of 35°W, one of only three tropical cyclones to do so in the Atlantic basin. Fred's remnants persisted for over ten days, and ultimately helped to trigger devastating floods across Georgia, as the former hurricane interacted with a cold front.

List of Storm Names
Accumulated Cyclone Energy (ACE) Rating
The list below shows the ACE for each storm in the season. The ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed for, so hurricanes that lasted a long time, as well as particularly strong hurricanes, have higher ACEs.
Names to be retired, if any, will be announced by the World Meteorological Organization in the Spring of 2010.
