Atlantic Paths Forecasters predict rough hurricane activity from 1999 through the next few decades. This is partly a result of the Atlantic conveyor belt, or the movement of water beside North America.
Hurricanes gain much of their power from warm winds and oceans.
Forecasters say the Atlantic basin is in for an era of intense hurricane activity in part because warm waters from the Caribbean are moving north as far as Greenland. The waters sink deep before moving south, creating the warm ocean environment that helps storms strengthen into hurricanes.
