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.
In order for a hurricane to form, two things must be present: a weather disturbance, such as a thunderstorm, that pulls in warm surface air from all directions and water at the oceanâs surface that is at least 80Â° Fahrenheit (27Â° Celsius).
