After a night of widespread power outages in Florida, Hurricane Matthew pushed slowly northward Friday, prompting officials to extend a hurricane warning into North Carolina and to issue blunt warnings of possible deadly flooding in South Carolina, including the city of Charleston.
South Carolina officials were particularly worried about high water, in the form of 8-foot storm surges, inundating barrier islands and bringing life-threatening flooding to historic Charleston.
Of the 500,000 people instructed to leave low-lying coastal areas, Haley said that more than 300,000 people had pulled out. Many of those who didn't, she said, were on Daniel Island, a 4,000-acre area on the east bank of the Cooper River in the city of Charleston.
As of 11 a.m. ET Friday, the hurricane, downgraded slightly to a Category 3, was located 35 miles east northeast of Daytona Beach, Fla., moving northwest at 12 mph, according to the National Hurricane Center. Matthew continued to pack sustained winds up to 120 mph, threatening devastating storm surges in a four-state area.
