From a NASA’s Earth Observatory:

Hurricanes need two basic ingredients to develop: warm, moist air and a relatively calm atmosphere. Late summer over the Atlantic Ocean provides both things. Ocean waters above about 27 degrees Celsius (80 Fahrenheit) give rise to the warm, moist air that fuels tropical storms, and winds that could tear a storm apart are light during the summer. Typically, the Atlantic is primed for hurricanes by early August, and the height of the hurricane season comes in September, though the official hurricane season runs from June 1 through November 30.

They have a great figure showing that the Gulf of Mexico is now warm and hurricane-ready. Get ready. It might be an interesting August.
