Hurricane Fabian

Hurricane Fabian was a powerful tropical cyclone that impacted Bermuda in early September during the 2003 Atlantic hurricane season. It was 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 sea surface temperatures and light wind shear. The hurricane attained a peak intensity of 145 mph (233 km/h) on September 1, and it slowly weakened as it turned northward. On September 5, Fabian made a direct hit on Bermuda with wind speeds of over 120 mph (190 km/h). After passing the island, the hurricane turned to the northeast, and became extratropical on September 8, before dissipating two days later.

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, better known as the cahow, 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 US$300 million in damage and eight deaths.

On August 25, a tropical wave emerged off the coast of Africa. Tracking westward, the wave developed convection over its center, and conducive conditions allowed it to develop further. The system passed through the Cape Verde islands later that day as convection steadily weakened. Early on August 27, convection again increased and consolidated near the center, and later that day the wave developed into Tropical Depression Ten while located 420 miles (680 km) west of the Cape Verde islands. Moving westward into an area of warm waters and low vertical shear, the depression steadily intensified, and was named Tropical Storm Fabian on August 28 as convection increased and banding features became more prominent.

Banding features and outflow continued to develop as a ring of convection formed around the center of Fabian, and on August 30, the storm intensified into a hurricane while gradually slowing its motion to the west-northwest. As banding features and outflow became better defined, an eye developed in the center of the deepest convection. Fabian quickly strengthened and attained major hurricane status late that day. Deep convection became very concentric around the 11.5 miles (18.5 km) wide eye, and the hurricane reached winds of 125 mph (201 km/h) early on August 31. At this time, the deepest convection near the eye degraded in appearance, and Fabian temporarily stopped its strengthening trend. Later that day, the eye became distinct again within a perfectly round area of deep convection. Outflow continued to expand in all directions, and Fabian intensified into a Category 4 hurricane late on August 31. Thunderstorm activity near the eyewall became more intense, and the cloud tops in the eyewall became much cooler; simultaneously, outflow away from the eye became much more symmetrical, both signs of an intensifying tropical cyclone. Fabian reached its peak intensity of 145 mph (233 km/h) on September 1 while located 345 miles (555 km) east of the northern Lesser Antilles.

After maintaining its peak intensity for 12 hours Fabian degraded due to internal fluctuations, and began to weaken. The hurricane turned to the northwest on September 2 in response to a weakness in the subtropical ridge, a break caused by a mid-level circulation over the southwest Atlantic Ocean. After fading back to a Category 3 hurricane, Fabian re-intensified on September 4, and regained Category 4 status for a short time. The hurricane weakened again as it accelerated northward towards Bermuda, a motion due to an approaching mid-level trough. As small pockets of dry air became entrained in the eyewall, Fabian weakened slightly, passing just 14 miles (23 km) west of Bermuda on September 5 as a 120 mph (190 km/h) Category 3 hurricane. The eastern portion of the eyewall moved over the island, resulting in a direct hit; the center did not move over the island, so Fabian did not make landfall. After passing the island, the hurricane accelerated northeastward, and weakened to a 105 mph (169 km/h) Category 2 hurricane on September 7. Steady weakening occurred as the hurricane moved into an area of increasing wind shear, drier air, and progressively cooler waters. On September 8, while located 680 miles (1,090 km) east-northeast of Cape Race, Newfoundland, Fabian transitioned into an extratropical storm, with no deep convection remaining near the center. Fabian's extratropical remnant turned to the north on September 9, and on September 10, Fabian's remnant merged with another extratropical storm while located between southern Greenland and Iceland.

Several days prior to Fabian striking Bermuda, computer models forecast a ridge of high pressure forcing the hurricane to the west of the island by 200 miles (320 km). Not expected to be a direct threat, a meteorologist at the Bermuda Weather Service expected gusty winds and potentially heavy rainfall. Each successive advisory was issued as the hurricane steadily moved closer to Bermuda, and 35 hours before Fabian made its closest approach, the Bermuda Weather Service issued a hurricane watch for the island. When a track near Bermuda became more certain, a hurricane warning was issued for the island, approximately 29 hours before Fabian made a direct hit on the island.

The Bermuda Electric Light Company Limited recommended Bermuda residents to buy hurricane supplies such as candles, batteries, and non-perishable foods, to fill bathtubs and extra containers with water, and fill gasoline tanks for automobiles. In preparation, residents formed long lines at gas stations, banks, and supermarkets. All government offices and many businesses closed on the day prior to the hurricane hitting. All schools were closed, while all flights in and out of the island were canceled. Officials opened emergency shelters, and recommended 2,000 low-lying residents to evacuate; a hotel on the south shore of the island was evacuated as well. Several cruise ships expected to remain on the island departed early to avoid the hurricane. Local insurance companies on Bermuda experienced a great increase in business, as residents renewed lapsed policies or signed up for new policies for homes or businesses, though marine policies were stopped several days before the hurricane struck. The arrival of Fabian forced the cancellation or delay of several sports events, including a cricket match, a football game, and a dinghy race.

Fabian killed eight people and caused US$300 million in damages, primarily in Bermuda.
