CHARLESTON, S.C.: Rescuers searched for survivors among the ruins of Florida's flooded homes from Hurricane Ian while authorities in South Carolina waited for daylight to assess damage from the storm's second strike as the remnants of one of the strongest and costliest disasters to ever hit the US continued to push north.

The powerful storm terrorized millions of people for most of the week, battering western Cuba before raking across Florida from the warm waters of the Gulf of Mexico to the Atlantic Ocean, where it mustered enough strength for a final assault on South Carolina. It has since weakened to a still-dangerous post-tropical cyclone and was crossing North Carolina toward Virginia overnight, pushing heavy rains toward the Mid-Atlantic states.
