Track map of the storms during the season

The 1972 Atlantic hurricane season is one of five Atlantic hurricane seasons not to have any major hurricanes, the others being 1968, 1986, 1994, and 2013. During the season, seven tropical or subtropical depressions formed, all of which became tropical or subtropical storms or hurricanes.[1] The season officially began on June 1, 1972 and ended on November 30. These dates typically limit the period of each year when most tropical cyclones form in the eastern Atlantic basin. This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation. The timeline also includes information which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned on, has been included.

The first storm of the season, Subtropical Storm Alpha, formed on May 23, before the season began on June 1. The final storm of the season, Subtropical Storm Delta, dissipated on November 7. There were seven tropical cyclones during the season. Of these, three were subtropical storm, and four were tropical. Of these tropical systems, three became hurricanes; none of these reached Category 3 intensity or higher on the Saffir-Simpson hurricane scale. Although it was an inactive season, 1972 brought one of the deadliest and most expensive hurricanes to strike the United States, Hurricane Agnes. Agnes was a weak but large storm that made landfall at the Florida panhandle and then followed the east coast northward. It killed 122 people and caused $2.1 billion (1972 dollars) in damage, mostly due to flooding in Pennsylvania and New York.[1]
