1930 Atlantic hurricane season The 1930 Atlantic hurricane season was the second least active Atlantic hurricane season on record – behind only 1914 – with only three systems reaching tropical storm intensity. Of those three, two reached hurricane status, both of which also became major hurricanes, Category 3 or higher storms on the Saffir–Simpson hurricane wind scale. The first system developed in the central Atlantic Ocean on August 21. Later that month, a second storm, the Dominican Republic hurricane, formed on August 29. It peaked as a Category 4 hurricane with winds of 155 mph (250 km/h). The third and final storm dissipated on October 21.
1939 Atlantic hurricane season The 1939 Atlantic hurricane season officially began on June 12, 1939, and lasted until November 7, 1939. These dates mark the period of each year when most tropical cyclones form in the Atlantic basin. The 1939 season had below normal activity, with only six tropical storms, of which two became hurricanes and one became a major hurricane, equivalent to Category 3 status or higher on the modern-day Saffir-Simpson Hurricane Scale. The first tropical cyclone formed on June 12, and the last dissipated on November 6.
