"Florence slowly weakening just inland over eastern SC but causing catastrophic flooding over North and SC", the National Hurricane Center (NHC) said early Saturday morning, after downgrading it from a hurricane to a tropical storm the previous day.
The NHC said Florence had the potential to dump historic amounts of rain on North and SC, as much as 40 inches (one meter) in some places. In the state's Pender County, a woman died of a heart attack; paramedics trying to reach her were blocked by debris.
At least five people, including a mother and her child, have been killed as Florence brings unending rain and storm surges to the region.More news: Cristiano Ronaldo Scores His Maiden Serie A Goal For Juventus

The White House said President Donald Trump was to visit hurricane-hit areas next week "once it is determined his travel will not disrupt any rescue or recovery efforts". By Friday evening, the eye of the storm had moved to SC. Gradual weakening is expected overnight and significant weakening is expected this weekend into next week as the storm moves farther inland. The homes of about 10 million were under watches or warnings for the hurricane or tropical storm conditions.
