Search-and-rescue teams fanned out across the Florida Panhandle to reach trapped people in Michael's wake Thursday as daylight yielded scenes of rows upon rows of houses smashed to pieces by the third-most powerful hurricane on record to hit the continental U.S.
At least six deaths were blamed on Michael, including one in North Carolina, and it wasn't done yet: Though weakened into a tropical storm, it continued to bring heavy rain and blustery winds to the Southeast as it pushed inland, soaking areas still recovering from last month's Hurricane Florence.
Under a perfectly clear blue sky, Florida families emerged tentatively from darkened shelters and hotels to an unfamiliar and perilous landscape of shattered homes and shopping centers, beeping security alarms, wailing sirens and hovering helicopters.
Over 900,000 homes and businesses in Florida, Alabama, Georgia and the Carolinas were without power.
"This morning, Florida's Gulf Coast and Panhandle and the Big Bend are waking up to unimaginable destruction," Gov. Rick Scott said. "So many lives have been changed forever. So many families have lost everything... This hurricane was an absolute monster."
But the full extent of the damage was only slowly becoming clear, with some of the worst areas difficult to reach. An 80-mile stretch of Interstate 10, the main east-west route along the Panhandle, was closed because of debris.
One of the hardest-hit spots was Mexico Beach, where Michael crashed ashore Wednesday as a Category 4 monster with 155 mph (250 kph) winds. Video from a CNN helicopter Thursday revealed widespread devastation across the town of about 1,000 people.
Entire blocks of homes near the beach were washed away, leaving nothing but concrete slabs in the sand. Rows and rows of other homes were reduced to piles of debris or crumpled and slumped at odd angles.
Scott said the National Guard got into Mexico Beach and rescued 20 people who survived the direct hit. The town was under a mandatory evacuation order as the rapidly developing storm closed in, but some people were determined to ride it out.
A day later, the beach town remained difficult to reach by land, with roads covered by fallen trees, power lines and other debris.
The governor pleaded with people in Florida not to go home yet.
"I know you just want to go home. You want to check on things, and begin the recovery process," Scott said. But "we have to make sure things are safe."
Meanwhile, the Coast Guard said it rescued at least 27 people, mostly from homes damaged along the Florida coastline, and searched for more victims. Among those brought to safety were nine people rescued by helicopter from a bathroom of their Panama City home after their roof collapsed, Petty Officer 3rd Class Ronald Hodges said.
Florida officials also said they were moving patients from damaged health care facilities.
As of 9 a.m. EDT, Michael was centered about 40 miles (65 kilometers) west of Columbia, South Carolina, with winds of 50 mph (85 kmh). It was moving at 21 mph (33 kmh).
The storm was expected to move across North Carolina and Virginia and push into the Atlantic Ocean by late Thursday or early Friday.
Along the 200-mile Panhandle, Michael washed away white-sand beaches, hammered military bases and destroyed coastal communities, stripping trees to stalks, shredding roofs, toppling trucks and pushing boats into buildings.
Authorities said a falling tree killed a man outside Tallahassee, Florida, and an 11-year-old girl in Georgia was killed when the winds picked up a carport and dropped it on her home. One of the carport's legs punctured the roof and hit her in the head.
An Associated Press team drove for miles and encountered extensive destruction around Panama City. Though most homes were still standing, no property was left undamaged.
Downed power lines lay nearly everywhere. Roofs were peeled away and sent airborne. Aluminum siding was shredded to ribbons. Homes were split open by fallen trees.
Hundreds of cars had broken windows. Twisted street signs lay on the ground. Pine trees were stripped and snapped off about 20 feet high.
Vance Beu, 29, was staying with his mother at her home at Spring Gate Apartments, a complex of single-story wood-frame buildings. They piled up mattresses around themselves for protection.
A pine tree punched a hole in their roof, and Beu's ears popped because of the drop in barometric pressure from the storm. The roar of the winds, he said, sounded like a jet engine.
"It was terrifying, honestly. There was a lot of noise. We thought the windows were going to break at any time," Beu said.
Sally Crown rode out Michael on the Panhandle thinking at first that the worst damage was the many trees downed in her yard. But after the storm passed, she emerged to check on the cafe she manages and discovered a scene of breathtaking destruction.
"It's absolutely horrendous. Catastrophic," Crown said. "There's flooding. Boats on the highway. A house on the highway. Houses that have been there forever are just shattered."
More than 375,000 people up and down the Gulf Coast were ordered or urged to evacuate as Michael closed in. But it moved so fast and intensified so quickly that people didn't have much time to prepare, and emergency authorities lamented that many ignored the warnings.
Based on its internal barometric pressure, Michael was the third most powerful hurricane to hit the U.S. mainland, behind the unnamed Labor Day storm of 1935 and Camille in 1969. Based on wind speed, it was the fourth-strongest, behind the Labor Day storm (184 mph, or 296 kph), Camille and Andrew in 1992.
