Hurricanes are given status based on the maximum sustained wind speed of the storm system. Specifically, when a storm reaches sustained wind speeds of 74 mph or higher, it is classified as a hurricane. Additionally, other factors like atmospheric conditions and the organization of the storm system are taken into account before making the classification.

Why was Hurricane Sandy caused?
Hurricanes are formed when light winds with high levels of humidity flow over warm sea surfaces. If the water temperature is above 78 degrees Fahrenheit (26C), storm conditions can grow quickly. Hurricane Sandy was first noticed on Oct 22, as a tropical wave in the western Caribbean Sea. She then picked up moisture from the warm waters while gaining strength. In six hours' time, she'd moved through tropical depression status to tropical storm status. Slowly moving northward and intensifying, she was upgraded to hurricane status on Oct 24.

How did hurricane Isaac start?
Hurricanes form in tropical regions where there is warm water, typically at least 80 degrees Fahrenheit and 27 degrees Celsius, moist air and converging equatorial winds. Most Atlantic hurricanes begin off the west coast of Africa and start out as thunderstorms that move out over the warm and tropical ocean waters. A thunderstorm reaches hurricane status in three stages. A tropical depression has swirling clouds and rain with wind speeds of less than 38 miles per hour. A tropical storm has wind speeds of 39 to 73 miles per hour and a hurricane has wind speeds greater than 74 miles per hour. It can take anywhere from a couple of hours to several days for a thunderstorm to develop into a hurricane. Chances are Hurricane Isaac began the same way most every hurricane starts.
