A hurricane needs humidity to develop. Humidity is the amount of  water in the air. A hurricane starts off as a series of  thunderstorms which intensify as it moves over the â¦ warm humid sea.  The humidity continues to grow over the sea. Any sort of decrease  or increase in humidity can change the strength of a hurricane.
Hurricanes form over warm water because it warms and moistens the air above it. This warm, moist ocean air is essentially the fuel of a hurricane. When a tropical disturbance, â¦ the precursor to a hurricane, lifts this air it cools and the moisture in it condenses, releasing enormous amounts of energy. Hurricane forms when an atmospheric disturbance with low pressure moves over warm, tropical waters. The warm, moist air fuels the storm and strengthens it. As it intensifies and begins to rotate, it becomes a tropical depression. When the winds reach 39 mph, it becomes a tropical storm and is given a name.
