Through Atlantic Ocean, Massachusetts and Cuba

One of the most significant storms of the season was Hurricane Carla, which peaked as a Category 4 hurricane, before striking Texas. Carla caused 43 deaths and approximately $325.74 million in damage. Hurricane Debbie was a Category 1 storm that existed in the eastern Atlantic Ocean. Early in its duration, unsettled weather from Debbie in Cape Verde resulted in a plane crash and the death of 60 people. The extratropical remnants of Debbie then brushed Ireland, causing severe damage over the British Isles. The next storm, Hurricane Esther, threatened to strike New England as a major hurricane, but rapidly weakened and made landfall in Massachusetts as only a tropical storm. Impact was generally minor, with about $6 million in damage and seven deaths, all of which from a United States Navy plane crash. An unnamed tropical storm and Hurricane Frances caused minimal impact on land. In mid-October, Tropical Storm Gerda brought flooding to Jamaica and eastern Cuba, resulting in twelve deaths.

Another significant storm was Hurricane Hattie, a late-season Category 5 hurricane that struck Belize. Hattie caused 319 confirmed fatalities and about $60.3 million in damage. Destruction was so severe in Belize that the government had to relocate inland to a new city, Belmopan. In early November, the depression that would later strengthen into Hurricane Jenny brought light rainfall to Puerto Rico. The final storm, Tropical Storm Inga, dissipated on November 8, after causing no impact on land. On September 11, three hurricanes existed simultaneously – Betsy, Carla, and Debbie – the most on a single day in the Atlantic basin since 1893 and until 1998. Collectively, the storms of the 1961 Atlantic hurricane season caused about $392.34 million in damage and at least 437 fatalities.

Season summary

The Atlantic hurricane season officially began on June 15. It was an above average season in which twelve tropical storms formed; this was above the 1950–2000 average of 9.6 named storms. Eight of these reached hurricane status, also above of the 1950–2000 average of 5.9. Furthermore, five storms reached major hurricane status. It was originally believed that the season had seven major hurricanes, though later analysis resulted in a downgrade of two storms. Of the five major hurricanes, two became Category 5 hurricanes. Four hurricanes and two tropical storms made landfall during the season, causing 348 deaths and $391.6 million in damage. Hurricane Debbie also caused damage and deaths, despite remaining offshore and then after becoming extratropical.

Tropical cyclogenesis began with an initially unclassified tropical depression, which developed on June 10. More than a month later, Hurricane Anna formed on July 17 and dissipated on July 24. Thereafter, no other systems developed in July or the month of August. A lack of cyclonic activity in the Atlantic basin in August is rare, with such phenomenon not occurring again until the 1997 and 2022 seasons. The Atlantic basin remained dormant until Hurricane Betsy developed on September 2. During the next four days, two other tropical cyclones formed – Carla and Debbie. On September 11, the three storms – Betsy, Carla, and Debbie – existed simultaneously as hurricanes, the most in a single day since 1893 and until 1998. Esther, which developed on September 10, did not reach hurricane status until September 12. Later that day, a tropical storm that went unnamed formed over the Bahamas and moved across the East Coast of the United States for its brief duration.

After Debbie became extratropical on September 14, another tropical cyclone developed over two weeks later, Hurricane Frances. Thereafter, tropical cyclogenesis slowed in October, which featured only three systems, a second previously unclassified tropical depression, Gerda, and Hattie. The latter was the strongest tropical cyclone of the season, peaking with maximum sustained winds of 165 mph (266 km/h) and a minimum barometric pressure of 914 mbar (27.0 inHg). After weakening slightly, Hattie struck Belize on October 31, before dissipating on November 1. Later that day, Hurricane Jenny developed northeast of Antigua. Jenny remained weak for much of its duration and became extratropical on November 8. The final system, Tropical Storm Inga, formed in the Gulf of Mexico on November 4. Four days later, Inga dissipated, one week before the season officially ended.

The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 189, one of the highest values recorded. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. It is only calculated for full advisories on tropical systems at or exceeding 39 mph (63 km/h), which is the threshold for tropical storm strength.
