Hurricane Ophelia off South Carolina

November 21, 2007
On September 11, 2005, Hurricane Ophelia remained poised off of the coast of South Carolina. This Category 1 hurricane, with maximum sustained winds of 65-70 knots or 75-80 miles per hour (1 knot = 1.15 mph), is the 16th major storm event of 2005. At 8 a.m. Eastern Daylight Time, Ophelia was about 345 kilometers (215 miles) East-Southeast of Charleston, South Carolina and moving very slowly in a Northwestward direction. The storm is close enough to the coast to pound beaches with powerful waves and to cause the evacuation of tourists from some barrier islands. Heavy rainfall is expected, totaling 5-10 cm (2-4 inches) along the North Carolina coast and slightly less in South Carolina. A hurricane is type of tropical cyclone, or a storm with maximum sustained winds of greater than 63 knots (73 mph). A tropical cyclone that is located in the in the North Atlantic is called a hurricane; a similar storm in Northwest Pacific Ocean, west of the International dateline, is called a typhoon. Cyclones are large, rotating regions of wind, clouds, and thunderstorms formed over warm tropical oceans.
