Hurricane Michael made landfall as a Category 4 hurricane, the biggest in the history of Florida.
Michael was recorded as the third strongest storm in recorded history to hit mainland America.
Before the storm hit forecasters warned some areas in Florida could see storm surge at eight to 12 feet high.
In the footage shared on social media from St. George Island in Florida homes were submerged under water with huge waves ploughing in.
The water was filled with debris including branches, and wood from fences.
A Floridan news anchor, Josh Benson, wrote: “LAWN OF WAVES. Unbelievable video of a yard of waves.
“It doesn’t look real. I’m a bit afraid to see what the sunrise holds for these people. This was in St. George Island.”
At least two people were killed by the impacts of the powerful storm which is still sweeping across mainland US, despite losing a huge amount of power.
The National Hurricane Centre (NHC) said in its latest public advisory at 7am BST Michael is moving towards the northeast and they expect the storm to reach central Georgia on Thursday afternoon.
The advisory read: “Michael is moving toward the northeast near 20 mph (31 km/h) and this general motion should continue this morning. A motion toward the northeast at a faster forward speed is expected later today through Friday night.
“On the forecast track, the core of Michael will move across central and eastern Georgia this morning, and then over southern and central South Carolina later today.”
The hurricane rapidly intensified in the Gulf of Mexico this week before becoming the most powerful storm ever recorded to hit the Panhandle.
More than 375,000 people up and down the Gulf Coast were warned to evacuate, and the hurricane’s leading edge sent storm surge into neighbourhoods as it approached.
Michael is expected to be even more powerful than Hurricane Florence, which had wind speeds of 90mph when it struck the Carolinas in September.
Only three major hurricanes have made landfall in the Florida Panhandle since 1950, Eloise in 1975, Opal in 1995 and Dennis in 2005.
Florida’s Governor Rick Scott urged residents to stay indoors and wait for first responders to arrive.
He wrote: “The roads need to be clear so they can respond as needed without inference.”
He added: “We are going to be aggressive with recovery and response over the coming days and will do everything we can to assist our communities that have seen impacts from this devastating storm.”
