The 2011 Atlantic hurricane season was an above average event in the yearly formation of tropical cyclones in the Atlantic Ocean, Caribbean Sea and Gulf of Mexico. This page will document my opinion on intensities during the season after seeing the information needed to form this opinion. This may include Dvorak numbers, Tropical Cyclone Advisories and reports, and any observations made during the tropical cyclone personally if it made landfall. Based on this summary, there were 20 tropical depressions, 19 tropical storms, 7 hurricanes, and 4 major hurricanes. This season is tied with 1887, 1995 2010 and 2012 for the 3rd most tropical storm or higher strength systems within an Atlantic hurricane season. Following the season, the name Irene was retired, and replaced with Irma for the 2017 season.
