Hurricane Michael, the worst storm to strike the U.S. in nearly 50 years, has left unbelievable destruction in its wake after pounding into the Florida Panhandle Wednesday and then tearing through Georgia and the Carolinas.
The power of the storm, which was a powerful Category 4 at landfall, was evident in dramatic footage that showed demolished homes, submerged neighborhoods, piles of downed trees and buses and even a massive freight train tossed around like toys.
At least 17 people have died from the storm from Florida through Virginia.

The conditions so bad that Zee and her team lost the ability to broadcast.
"All I can see is devastation," Zee said.

On Thursday, Zee ventured out onto the sand- and debris-covered highway and posted this photo of the aftermath in Mexico Beach.
"Finally have service and will try to tweet the photos I am able to as I know many of you are desperate to know what’s left," she wrote. "Survivors gave me numbers to call and I have. Powerful phone calls telling their loved ones they are alive."

A few more pics that may help those from Mexico Beach get a hold on what’s what. There is very little salvageable in the whole town. Tonight on @ABCWorldNews with @DavidMuir you’ll hear about the survivors that swam with life preservers through the surge. Unbelievable story. pic.twitter.com/bKCdy8c4Ai

These before and after images show how Michael demolished Mexico Beach.
Before Michael hit, law enforcement made a list of everyone in the small Mexico Beach community who stayed behind.
Now, "a tremendous number of people" are "unaccounted for," Mark Bowen, chief of emergency services in Bay County, which encompasses Mexico Beach, told "Good Morning America" Friday.
Rescuers' top priority Friday is a "meticulous" search process, he said, "everything from looking for bodies to looking for injured persons."
(MORE: How to help those affected by Hurricane Michael, the strongest US storm since 1969)"Fire stations were destroyed, police stations were destroyed," Bowen said. "Public safety agencies are only taking highest priority calls right now ... heart attacks, you know, major trauma. ... An enormous amount of 911 calls are going unresponded to because we’ve got this priority to search and rescue. So it’s a terrible thing."
Another photo out of Mexico Beach shows an American flag standing amid piles of debris.
Portions of the power grid along the coast including Mexico Beach were completely destroyed by the strong winds and storm surge and will need to be rebuilt, according to Duke Energy.
Video from Apalachicola, Florida, shows dozens of abandoned vehicles submerged in water and other destruction left in the wake of the storm.
The winds were strong enough to pierce the windshield of a car in Panama City Beach.

Northwest Florida Daily News reporter Annie Blanks tweeted video footage of seawater flowing inside the Dewey Destin's seafood restaurant near Mexico Beach.

The Lanark Fire Department tweeted video of a terrifying storm surge creeping up the shore, bringing seawater into a carport of a beachfront home.
Strong waves overtook a boat ramp to Choctawhatchee Bay at Legion Park, a video posted to Instagram by Lars Rygaard shows.
Customs and Border Patrol captured this video of a Black Hawk aircrew rescuing two people from an area that was inaccessible by car.

Tangie Horton, who lives inland from Mexico Beach, tearfully detailed the devastation in a Facebook video, saying, "I don’t know if I can get through this or not but we’re okay."
"This is where we were at when it hit ... can you imagine the people that was in Mexico Beach? We can’t find four of our friends but they’re still looking," she said. "It's just so sad ... it's just devastating."
She said she felt lucky that she made it through alive and with her camper intact.
Workers at the Walton County Animal Shelter were seen comforting dogs and cats up for adopting as they ride out the storm.
Love through the storm. ??

Michael is the strongest hurricane to strike the Florida Panhandle since the mid-1800s, according to FEMA.
Maj. DeWitt Revels of the Florida Army National Guard told ABC News Michael is "probably the worst one that I've seen."
"We're members of the community, too, so we all feel it," he added.

After pummeling Florida, Michael barreled through Georgia.
The weakened storm then continued north, toppling trees and power lines in North Carolina and triggering flash flood warnings in areas like Roanoke, Virginia.
Carolinas customers: high winds and toppled trees have brought down power lines as a result of #Michael. Stay away from fallen or sagging power lines -- consider all lines dangerous.
