Hurricanes are giant, spiraling tropical storms that can pack wind speeds of over 160 miles (257 kilometers) an hour and unleash more than 2.4 trillion gallons (9 trillion liters) of rain a day. Hurricanes begin as tropical disturbances in warm ocean waters with surface temperatures of least 80 degrees Fahrenheit (26.5 degrees Celcius). These low pressure systems are fed by energy from the warm seas. If a storm achieves wind of 38 miles (61 kilometers) an hour, it becomes known as a tropical depression. A tropical depression becomes a tropical storm, when its sustained wind speeds top 39 miles (63 kilometer) an hour. When a strom’s sustained wind speeds reach 74 miles (119 kilometers) an hour, it becomes a hurricane and earns a category rating of 1 to 5 on the Saffir-Simpson. If a storm achieves wind speeds of 74 miles an hour, it becomes a ....
