"It truly is really about the whole size of this storm," National Hurricane Center Director Ken Graham said. "The larger and the slower the storm is, the greater the threat and the impact—and we have that."

As of 11 a.m. EDT, Florence was centered about 145 miles (230 kilometers) southeast of Wilmington, its forward movement slowed to 10 mph (17 kph). Hurricane-force winds extended 80 miles (130 kilometers) from its center, and tropical-storm-force winds up to 195 miles (315 kilometers).
