Florence is expected to blast coastal areas, and possibly areas further inland, between Thursday and Saturday. Weather models show the storm slowing down or stalling over or near the Carolinas, thus increasing the chances of dangerous rainfall levels.
Virginia, North Carolina, and South Carolina have issued mandatory evacuation orders of coastal communities forecast to be in the storm's path.
