Storm flooding leveled off along the Gulf Coast as of 11 p.m. ET, the National Hurricane Center said.
Damage in Panama City was extensive, with broken and uprooted trees and power lines down almost everywhere.
The storm knocked the broadcast of Panama City-based WMBB off the air after the television station lost power, one of more than 263,000 customers experiencing blackouts in Florida. His office said he would tour the devastated areas next week.
Michael had top sustained winds of 150 miles per hour as its core moved over Florida's Panhandle earlier in the afternoon as forecasters warned rain could reach up to a foot and the life-threatening storm surge could swell to 14 feet (4m). You are not going to survive it. It's very, very scary.
"We haven't seen her since the tree hit the den".
"This happened so quickly, we weren't exactly prepared", he said. As we saw during last month's Hurricane Florence in the Carolinas, it's likely that thousands of people couldn't even afford to evacuate.
"Satellite images of Michael's evolution on Tuesday night were, in a word, jaw-dropping", wrote meteorologist Bob Henson.
Hurricane Michael has battered the Gulf Coast - becoming the biggest storm to strike the Florida Panhandle, the state's northwest, since records began in 1851.
"We are attempting to get to the home".
Catastrophe risk modelling and analysis firm Corelogic has just released an estimate of the insured losses from storm surge and hurricane force winds, which is based on the landfall factors hence this is not a post-landfall estimate of industry losses.
More than 40 percent of daily crude oil production and more than one-third of natural gas output was lost from offshore US Gulf of Mexico wells on Wednesday because of platform evacuations and shut-ins caused by Michael.
The aircraft also reported that the minimum pressure has fallen to 923 millibars, meaning more strengthening could occur before landfall by mid-afternoon Wednesday.
Even before landfall, the hurricane disrupted energy operations in the Gulf, cutting crude oil production by more than 40% and natural gas output by almost a third as offshore platforms were evacuated ahead of the storm's arrival.
"The center of Michael is now moving into south-central Georgia".
So it will take some time for the full scale of the property damage from hurricane Michael to be understood.
She could not say what time the death occurred or give any details about the victim.
About 3,500 Florida National Guard troops were deployed to assist with evacuations and storm recovery, along with more than 1,000 search-and-rescue personnel, Scott said.
At 11 a.m., the core of extremely unsafe Hurricane Michael was closing in on the Florida Panhandle in the area of Panama City.
Heavy rainfall was projected for areas in the storm's path.
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.
