A map of the Atlantic Ocean depicting the tracks of 20 tropical cyclones.
2011年所有在大西洋的熱帶氣旋軌跡圖。

2011年大西洋颶風季是一次活躍程度高於平均水平的大西洋颶風季,共計有19個颶風[注 1]。這也是第一次在颶風季的首八個熱帶氣旋未能形成颶風狀態。雖然熱帶風暴阿琳6月28日形成,颶風季正式是從從2011年6月1日正式開始,同年11月30日結束。傳統上這樣的日期界定了一年中絕大多數熱帶氣旋大西洋盆地形成和發展的時間段[2]。本季的最後一個氣旋是熱帶風暴肖恩,於11月11日消散。

The season produced twenty tropical depressions, of which nineteen further intensified into tropical storms; seven strengthened hurricanes, and four hurricanes ultimately intensified into major hurricanes.[nb 1] This makes 2011 the third most active hurricane season on record, along with 1887, 1995, and 2010.[4] The two most significant storms, in terms of loss of life and damage, were Hurricane Irene and Tropical Storm Lee. Hurricane Irene was a powerful and unusually large storm that made several landfalls along the East Coast of the United States after peaking with maximum sustained winds of 120 mph (195 km/h).[5] Tropical Storm Lee was a disorganized tropical cyclone that moved ashore the coastline of Louisiana before producing historic flooding in the Northeast United States as an extratropical cyclone.[6]

This timeline includes information that was not operationally released, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not operationally warned upon, has been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.
