The most powerful hurricane ever to hit north-west Florida has flooded beach towns, submerging homes and snapping trees like twigs.
Hurricane Michael made landfall on Wednesday afternoon as a category three storm with 125mph (200km/h) winds in the state's Panhandle region.
One person was killed by a falling tree, Florida officials say.
The storm left nearly 500,000 people without electricity in Florida, Alabama and Georgia, emergency services say.
Michael was so powerful that it remained a hurricane as it moved further inland.
Its rapid intensification caught many by surprise, although the storm later weakened.
