Back in 2005, Hurricane Katrina and Hurricane Rita ballooned into monster storms in the Gulf of Mexico due to increased water temperatures driven by a current of warm water that travels between Cuba and the Yucatan Peninsula. This is called The Loop Current.
If a tropical storm develops over this current, it can build and strengthen extremely fast. The loop current could play a pivotal role in hurricane development this season in the gulf and subsequent landfalls.
