JACKSONVILLE BEACH, Fla./CHARLESTON, S.C., Muharram 7, 1438, Oct 8, 2016, SPA -- Hurricane Matthew slammed into South Carolina on Saturday, packing a diminished yet still powerful punch after killing almost 900 people in Haiti and causing major flooding and widespread power outages as it skirted Florida and Georgia, Reuters reported. The most powerful Atlantic storm since 2007 left flooding and wind damage in Florida before moving north to soak coastal Georgia and the Carolinas. Earlier on Saturday, wind speeds had dropped below 85 miles per hour (135 kph), making it a Category 1 hurricane, the weakest on the Saffir-Simpson scale of 1 to 5. Matthew, which topped out as a Category 5 more than a week ago, made landfall near McClellanville, a village 30 miles north of Charleston that was devastated by a Category 4 hurricane in 1989. The National Hurricane Service warned of serious flooding in the area as the storm drove inland. At least four deaths in Florida were attributed to the storm, which knocked out power to least 1.5 million households and businesses in the southeastern United States. The stretch of the Atlantic coast from Miami to Charleston, a nearly 600-mile drive, encompasses some of the most well-known beaches, resorts and historical towns in the southeastern United States. In Florida, 775,000 were without power, according to state utilities, while in South Carolina 433,000 had no electricity, Governor Nikki Haley said. Georgia Power said at least 275,000 were without power in the state. Roads in Jackson Beach were littered with wood, including sections of a historic pier, and foot-deep (15 cm) water clogged intersections. Beachfront businesses suffered moderate damage. -- SPA 19:57 LOCAL TIME 16:57 GMT www.spa.gov.sa/w
