(NBC News) Hurricane Matthew continued to whip up the southeastern seaboard Saturday, killing at least nine people after thrashing Florida and toppling trees and power lines and washing out roads, officials said.

Matthew made landfall Saturday morning south of Myrtle Beach, South Carolina, after dousing historic cities and slashing power to hundreds of thousands.

The storm weakened to a Category 1 hurricane overnight after being blamed for at least four deaths in Florida. Matthew was also linked to two deaths in Georgia on Saturday and three in North Carolina.
