At least six deaths have been blamed on Michael, the most powerful hurricane to hit the continental U.S. in over 50 years.
Some fear the toll can only rise as rescue teams get around storm debris blocking roads and reach isolated areas.
The sheriff's office in Gadsden County near Tallahassee says it "can now confirm 4 storm-related fatalities following Hurricane Michael," all of which happened "in relation to or occurred during the storm." County officials say they're not releasing names or other details yet while families are notified.
One of those deaths would be a man killed by a falling tree. An 11-year-old girl in Georgia also died when Michael's winds picked up a carport and dropped it through the roof of her grandparents' home. A driver in North Carolina was killed when a tree fell on his car.
Tropical storm Michael has sped off towards the Atlantic Ocean, but there will be nothing quick about Florida's recovery from the hurricane, where rows upon rows of homes have been smashed to pieces.
The storm also has brought flash flooding to hurricane-weary parts of North and South Carolina and Virginia.
By The Numbers
— Hurricane history: first Category 4 hurricane to make landfall in Florida's Panhandle since record-keeping began in 1851.
— Top winds: 155 mph (250 kph), strong enough to completely destroy homes and cause weeklong power outages.
— Powerful pressure: 919 millibars minimum pressure in the eye, the third most intense hurricane landfall in the U.S. in recorded history.
— High water: estimated peak storm surge of 9 feet (2.75 meters) and 14 feet (4.25 meters) from Mexico Beach east through Apalachee Bay, according to the National Hurricane Center.
— Storm riders: Roughly 375,000 people in Florida warned to evacuate; many refused, including 285 people in Mexico Beach where Michael made landfall.
— Rescued: 47 helped out of hard-hit areas along Florida's coastline, and 20 people in flooded neighborhoods in North Carolina.
— Staying safe: nearly 6,700 people took refuge in 54 shelters in Florida.
— Power outages: Roughly a million customers in Georgia, Florida, Alabama and South Carolina lost power.
— Food and water: 2 million ready-to-eat meals, 1 million gallons (3.75 million liters) of water and 40,000 10-pound (4.5-kilogram) bags of ice ready for distribution in Florida.
— The human cost: Falling trees have killed a man in Gadsden County, Florida; a man in Iredell County, North Carolina; and an 11-year-old girl in Seminole County, Georgia, was killed when a carport blew through the roof of her home.
— Damage estimates: Boston-based Karen Clark & Company, an insurance company that produces models for catastrophes, is estimating Hurricane Michael caused about $8 billion in insured losses. It includes the privately insured wind and storm surge damage to residential, commercial and industrial properties and automobiles. The figure does not include losses covered by the National Flood Insurance Program.
Mexico Beach
One of the hardest-hit spots in Florida is Mexico Beach , where Michael crashed ashore. In a beach town home about 1,000 people, entire blocks of homes have been reduced to nothing but concrete slabs in the sand or piles of splintered lumber.
Flash Flooding
Michael left North Carolina behind with rivers rising and more than 530,000 households in the dark. The power outages were concentrated in central North Carolina's Piedmont region, where motorists had to be rescued Thursday from cars trapped by high water. Flashing flooding also was reported in the big North Carolina cities of Charlotte and Raleigh. Similar scenes played out in parts of Virginia as the storm raced seaward.
Hospitals Evacuated
The largest hospitals in Panama City shut down and evacuated hundreds of patients due to heavy hurricane damage. Bay Medical Sacred Heart was moving about 200 patients from buildings with blown-out windows, a cracked exterior wall and a collapsed roof. State officials say Florida's largest psychiatric hospital has been "entirely cut off." Florida State Hospital in Chattahoochee has been running on emergency generators. A helicopter dropped water and food at the facility on Thursday after a tree downed during the storm caused a water line to break.
Base Closure
Tyndall Air Force Base in Florida is closed while officials assess what they're calling "widespread catastrophic damage." No injuries were reported, but there's roof damage to "nearly every home" on the base.
No Extension
A federal judge rejected a push by Democrats to extend Florida's voter registration deadline, which was Tuesday, by a week. Florida Secretary of State Ken Detzner told local election supervisors that if their offices were closed due to the hurricane, they could accept paper applications when their offices reopen.
Damaged Crops
Georgia's Department of Agriculture Commissioner Gary W. Black said crops, animals and infrastructure have all taken a substantial loss because of the storm. Black says poultry contributes $23.3 billion to Georgia's economy and has reported the most widespread power outages and losses. Intense winds also hurt cotton crops.
Stormy Weather
Michael isn't alone. The National Hurricane Center says Hurricane Leslie and Tropical Storm Nadine are no threat to land over the open Atlantic Ocean, but Tropical Storm Sergio in the Pacific is blowing toward Mexico's Baja California Peninsula.
