WASHINGTON — To whip up a monstrous storm like the one chugging for the Carolinas you need a handful of ingredients — and Florence has them all. Higher sea levels to make a storm surge worse. That means the more trees that could fall, the more power outages,” National Hurricane Center Director Ken Graham said. And with the Appalachian Mountains to the west, there could be flooding and mudslides, experts worry. The ocean waters that Florence is travelling over are about 2.7 degrees (1.5 degrees Celsius) warmer than normal, McNoldy said.
