Hurricane Basics Tropical Cyclones A hurricane is a type of tropical cyclone, which is a generic term for a low pressure system that generally forms in the tropics. The cyclone is accompanied by thunderstorms and, in the Northern Hemisphere, a counterclockwise circulation of winds near the earth's surface. Tropical cyclones are classified as follows:
Hurricane Basics Hurricane Categories Hurricanes are classified into five categories. Category one being the most minimal hurricane and category five being the most destructive with wind speeds in excess of 155 miles per hour. A category 4 storm is expected to cause 100 times the damage of a category 1 storm.
Hurricane Basics Storm Surge The storm surge is created by wind, waves, and low pressure There are three mechanisms that contribute to the storm surge:
The action of the winds piling up water (typically more than 85% of the surge).
Waves pushing water inland faster than it can drain off. This is called wave set-up. Wave set-up is typically 5 - 10% of the surge.
The low pressure of a hurricane sucking water higher into the air near the eye (typically 5 - 10% of the surge).

Hurricane Basics High Winds High winds are the second element of a storms force. At the right you can see wind damage caused by Hurricane Fredric at the top of the screen. The picture on the lower right is the inside of Burger King’s CEO’s office in Miami after winds from Hurricane Andrew struck. While the storm surge is a costal concern, high winds from a hurricane can impact inland areas as well. Wind speeds drop significantly after landfall, however winds can stay above hurricane strength well inland. We have had tropical storms and hurricanes impact cities well to the north of the Gulf coast. In 1989 when Hurricane Hugo struck the Carolina coast, winds caused significant damage in Charlotte over 175 miles inland with gusts of 100 miles per hour.
