Of those storms, between 6 and 10 were likely to become hurricanes , and between 3 and 6 of those hurricanes could have become major hurricanes (category 3, 4, or 5).
What adds energy to a hurricane as it forms?
The secret energy source of a hurricane is the large latent heat of water. Air over the tropical oceans is drier than you might think. Increased evaporation means more water vapor in the air and more energy ready to be liberated in the hurricane’s thunderstorms as water vapor condenses.
