What weakens hurricanes when they reach the Atlantic Ocean

"Cooler Sea surface temperatures less than 79 degrees Fahrenheit (26 degrees Celsius)

High vertical wind shear.

Dry air.

Land masses along the projected storm track."-https://www.hurricaneville.com/decaying_factors.html

Explanation:

As less moisture is evaporated into the atmosphere to supply cloud formation, the storm weakens. Sometimes, even in the tropical oceans, colder water churned up from beneath the sea surface by the hurricane can cause the hurricane to weaken.
