context_page_description: The 1972 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. It was a significantly below average season, having only four fully tropical named storms, the fewest since 1930. It was one of only five Atlantic hurricane seasons since 1944 to have no major hurricanes, the others being 1968, 1986, 1994, and 2013. The season officially began on June 1, 1972 and ended on November 30, 1972. These dates, adopted by convention, historically describe the period in each year when most tropical systems form. However, storm formation is possible at any time of the year, as demonstrated in 1972 by the formation of Subtropical Storm Alpha on May 23. The season's final storm, Subtropical Storm Delta, dissipated on November 7.
  The season produced nineteen tropical or subtropical cyclones, of which seven intensified into tropical or subtropical storms; three became hurricanes, of which only but only one, Betty, had sustained winds greater than minimum hurricane force. Despite its relative inactivity, the 1972 season resulted in one of the worst natural disasters in American history, Hurricane Agnes.
