Hurricane Creation Hurricane Creation H urricanes are formed over tropical oceans where there are warm waters, humid air and converging winds. It takes a lot of energy for a hurricane to be created- not to mention just the right conditions.
Hurricanes start out as a group of storms that begin to rotate when they encounter converging winds.
T hese storms create violent seas, stirring up even more water into the air in the form of vapor. The water vapor rises very quickly, rotating with the storms, and helping to increase the wind speed. The storms begin to organize, holding themselves together and forming a center rotation point of low pressure. When this occurs, and sustained wind speeds reach 74 mph, the storms become a hurricane.
