In meteorology, a tropical cyclone (also referred to as a hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, and simply cyclone depending on strength and geographical context) is a storm system characterized by a low pressure center and numerous thunderstorms which generally forms in the tropics. While they can be highly destructive, tropical cyclones are an important part of the atmospheric circulation system, which moves heat from the equatorial region toward the higher latitudes. They develop over large bodies of warm water, and lose their strength if they move over land. This is the reason coastal regions can receive significant damage from a tropical cyclone, while inland regions are relatively safe from receiving strong winds.

Hurricane Fabian was a powerful Cape Verde-type hurricane that hit Bermuda in early September during the 2003 Atlantic hurricane season. Fabian, the sixth named storm, fourth hurricane, and first major hurricane of the season, developed from a tropical wave in the tropical Atlantic Ocean on August 25. It moved west-northwestward under the influence of the subtropical ridge to its north, and steadily strengthened in an area of warm water temperatures and light wind shear. The hurricane attained a peak intensity of 145 mph (230 km/h) on September 1, and it slowly weakened as it turned northward. On September 5, Fabian made a direct hit on the island of Bermuda with wind speeds of over 120 mph (195 km/h). After passing the island, the hurricane turned to the northeast, and became extratropical on September 8.

Fabian was the strongest hurricane to hit Bermuda since Hurricane Arlene in 1963. It was both the most damaging and the first hurricane to cause a death on the island since 1926. The hurricane's powerful winds resulted in moderate damage and destroyed roofs throughout the island. A strong storm surge associated with the hurricane killed four people crossing a causeway on Bermuda, temporarily closing the only link between two islands. The endangered Bermuda Petrel was threatened by the hurricane, which destroyed ten nests, although volunteer work transported the species to a safer location. Strong swells resulted in damage in northern Puerto Rico and the Dominican Republic, and also caused four people to drown along the United States' Atlantic coast. In all, Fabian caused around $300 million (2003 USD) in damage and eight deaths.
