Florida families are starting to emerge 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, the Associated Press reported midday Thursday.
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.
Michael was a Category 4 storm, just shy of a rare Category 5, when it came ashore. "We're going to be out of running water pretty shortly, I'm sure", she said.

POWER RESTORATION. Utility workers fix power lines in the aftermath of Hurricane Michael in Panama City, Florida, on October 12, 2018. "This hurricane was an absolute monster".

More than 375,000 people up and down the Gulf Coast were ordered or urged to evacuate as Michael closed in. Michael pushed a 10-foot (3-meter) storm surge and 155 miles per hour (249 kph) winds, just shy of a Category 5 hurricane, and Mexico Beach got the worst of it.
The hurricane disrupted energy operations in the U.S. Gulf of Mexico as it approached land, cutting crude oil production by more than 40 percent and natural gas output by almost one-third as offshore platforms were evacuated. "All of my furniture was floating", she said.
