Dozens of Florida residents left their flooded and splintered homes by boat and by air on Saturday as rescuers continued to search for survivors in the wake of Hurricane Ian, while authorities in South Carolina and North Carolina began taking stock of their losses.

The death toll from the storm, one of the strongest hurricanes by wind speed to ever hit the United States, grew to more than four dozen, with 47 deaths confirmed in Florida, four in North Carolina and three deaths in Cuba.

The storm weakened Saturday as it rolled into the mid-Atlantic, but not before it washed out bridges and piers, hurdled massive boats into buildings onshore and sheared roofs off homes, leaving hundreds of thousands without power.

The bulk of the deaths confirmed in Florida were mostly from drowning in storm waters, but others from Ian’s tragic aftereffects. An elderly couple died after their oxygen machines shut off when they lost power, authorities said.
