In the video wind gusts up to 150 miles per hour are seen ripping off the roofs of houses and buildings and even pushing down walls.
Residents and officials were taking stock of the damage on Thursday.
"I fear based of the images we're seeing, the damage is just so severe that this is going to be a long recovery process", Gillum told CNN. "We worked all night in endangered circumstances". She was among an estimated 280 Mexico Beach residents who decided not to evacuate, administrator Tanya Castor said. The area is known for its small beach towns, wildlife reserves and the state capital, Tallahassee.
Hurricane Michael claimed its first life after roaring ashore in Florida on Wednesday, October 10, flooding homes and streets and toppling trees and power lines in the Gulf of Mexico beachfront area where it made landfall as a raging Category 4 storm. Widespread power outages are expected to stretch from parts of the Florida panhandle up through Georgia as well as the Carolinas, but anyone within reach of the storm's rapid winds should be prepared to be without power at some point over the next few days.
At least one person is dead and hundreds of thousands of homes are without power as Hurricane Michael moves inland from Florida to Georgia.
One of the hardest-hit spots was Mexico Beach, where Michael crashed ashore Wednesday as a Category 4 monster with 155 miles per hour (250 kph) winds.

"Michael was different than others, because the track pretty much stayed the same from day one", said Capt. Kelsie Carpenter, 53rd WRS aerial reconnaissance weather officer, who flew into the storm on Tuesday morning. Winds will also be noticeable over Cape Cod and the Islands.
After being battered for almost 3 hours by strong winds and heavy rains, roads in Panama City were virtually impassable and trees, satellite dishes and traffic lights lay in the streets.
Based on its internal barometric pressure, Michael was the most powerful hurricane to blow ashore on the U.S. mainland since Camille in 1969.
With a low barometric pressure recorded at 919 millibars, the measure of a hurricane's force, it ranked as the third strongest storm on record to make landfall in the continental United States.
Hurricane Michael hit the Florida Panhandle Wednesday as the most powerful hurricane on record.
"I grew up in southwest Florida", says Brown, "and we had the eyes of storm go over us every summer but for some reason it's scarier here because the damage will come from the wind".
It's the worst storm to hit the Florida panhandle in over a century.
