Hurricane Floyd


On September 7, 1999 at 21Z, TD8 formed about 1000 miles east of Martinique in the Lesser Antilles. Less than 2.5 days later, the storm had reached Category 1 intensity.

The storm continued WNW and gained strength, eventually reaching a maximum intensity during the morning of Sep 13 with winds of 155mph and a central pressure of 921mb. The circulation associated with Floyd was over 1400 miles in diameter. He was a borderline CAT5 hurricane... and still headed toward the US east coast.

On the afternoon of Sep 14, Floyd went right over the northern Bahama islands with 140mph sustained winds, causing tremendous damage there. Shortly after this encounter, the hurricane began to head more northwesterly, threatening residents in FL, GA, SC, and NC. It was at this time that the "largest peacetime evacuation in the country's history" took place... 2.6 million coastal residents fled their homes for a safer inland location.

A more northerly motion began as the storm passed east of Jacksonville, FL, taking it toward Savannah, Charleston, and Wilmington. Buoys off the southeastern seaboard were recording wave heights of 30, 40, and up to 55 feet. In the early morning hours of Sep 16, Floyd made landfall on Cape Fear, NC with 110mph sustained winds. Flooding rains proved to be the largest impact the hurricane had on the United States... 16 states suffered some form of flash flood damage (some parts of SC and NC received about 2.5 feet of rain). Areas closer to landfall also had to contend with damaging winds and isolated tornadoes. In the end, Floyd was repsonsible for 56 American fatalities.
