Florence claims lives of at least 17, as catastrophic, widespread flooding impacts Carolinas

The death toll attributed to Florence stands at 17, including 11 in North Carolina and six in South Carolina.

The South Carolina Highway Patrol says a pickup truck was traveling west on Interstate 20 in Kershaw County on Sunday morning when it went off the roadway. Troopers say the truck struck an overpass support beam, and the driver died at the scene.

Kershaw County Coroner David West says the driver's name has not been released because all relatives have not yet been notified.

Heavy rain has fallen on portions of central and eastern South Carolina after former hurricane-turned-Tropical Depression Florence moved onshore.

As the death toll from Florence grew and hundreds of people were pulled from flooded homes, North Carolina braced for catastrophic, widespread river flooding that could be the next stage of a mounting disaster.

Weakened to a tropical depression early Sunday after blowing ashore as a hurricane with 90 mph (145 kph) winds on Friday, Florence was still spinning slowly atop the Carolinas as it pulled warm water from the ocean and hurled it onshore.

The storm's death toll climbed to 14 when a man drowned after a pickup truck flipped into a drainage ditch along a flooded road in South Carolina. Earlier, authorities said two people died from inhaling carbon monoxide from a generator in their home.

Authorities say the storm did not cause some other deaths that occurred during Florence in North Carolina: a woman who died of undetermined causes in a shelter, a woman who suffered a heart attack at home during the storm, and a couple whose apparent murder-suicide was investigated during hurricane conditions in Otway.

The death toll attributed to Florence stands at 17, including 11 in North Carolina and six in South Carolina.
