Cyclones in the Atlantic

938 named systems have been recorded in the Atlantic basin (this also includes the Caribbean Sea and the Gulf of Mexico) since 1951. It is possible that some were not very well assessed at the beginning of the period, before satellite imagery became relevant and ubiquitous.

Almost half (460) of these systems did not exceed the tropical storm stage. The remaining 476 strengthened to hurricane stage. 193 became major hurricanes (Cat. 3 and above) and 31 became category 5 hurricanes.

It is important to note that the sum of Cat. 4 and Cat. 5 hurricanes (117) is 54% greater than the number of Cat. 3 hurricanes. This is very important because it indicates that Cat. 3 hurricanes are 1,5 times more likely to strengthen than to stabilize. This is important to keep in mind.

Distribution of cyclones by season

Number of cyclones and ACE intensity

We can see that, overall, ACE (Accumulated Cyclone Energy) is correlated with the number of systems in a season. There are however notable exceptions like the 2017 season which with 17 named cyclones was a little above average (13) is the 5th most intense season compared to the ACE index. In the other direction, the 2020 season which is the 1st in number of systems (26) has an ACE index of 180, i.e. less than the 9th in history since 1951. 

The 10 most violent cyclones

The islands listed as affected were not necessarily impacted at the peak of the hurricane's intensity. For example, Hurricane Gilbert in 1988, the second most intense cyclone in the Atlantic, passed over Martinique as a tropical storm. To see the strongest cyclones that have affected an island, visit the island cyclone statistics.
