(CNN) Even for a major hurricane, Florence is a beast like no other. Before it pummels the US coastline, Florence could become close to a Category 5 storm -- meaning winds could approach 157 mph. That would be Florence's storm surge, the Federal Emergency Management Agency said. "Storm surge has the highest potential to kill the most amount of people," FEMA Administrator Brock Long said. Storm surge is basically a wall of water that could swallow parts of the coast.
