Irma killed one person in Georgia as storm surge and rain flooded coastal communities Monday, winds sent trees crashing onto homes and the world's busiest airport in Atlanta canceled hundreds of flights as the storm's punch was felt statewide despite its weakened status as a tropical storm.
Statewide, an estimated 13 million people, or two-thirds of Florida's population, remained without power.
All of Georgia Power's resources are being held and dedicated to storm restoration efforts in the state following Hurricane Irma. Authorities in Georgia said Monday that at least two people had died due to Irma.
Several people have lost their lives across southern Florida in vehicle accidents which may well be blamed on the storm once police have a chance to investigate.
In South Carolina, a storm surge warning continued to be in place from the South Santee River, south to the Georgia border, the Hurricane Center said. As of Tuesday morning, power had been restored to about 40 percent of those customers.
Irma was the strongest Atlantic storm to ever exist outside of the Caribbean and the Gulf of Mexico with 185 miles per hour sustained winds.
That's because, in this hemisphere, a cyclone rotates counterclockwise, and on the east side of the storm, the "outer bands come on shore at an angle typically bringing winds from the southeast", CNN meteorologist Taylor Ward said.
Another 700,000 people were asked to evacuate in Florida before Hurricane Irma, and numerous new evacuations being along the western coast of the state, according to the Associated Press.
An apparent tornado spun off by Irma destroyed six mobile homes in Palm Bay, midway up the Atlantic coast. Brock said no injuries had been reported.
Irma was at one time the most powerful hurricane ever recorded in the open Atlantic, with a peak wind speed of 185 miles per hour (300 km/h) last week.
"It's a worst-case scenario for Florida on the west coast", said FEMA Administrator Brock Long.
"People are frustrated when they're the isolate outage, we understand that, but we try to focus our resources", Kraft said.
Major tourist attractions, including Walt Disney World, Universal Studios and Sea World, all prepared to close Saturday.
The military was helping in relief operations, with the USS Abraham Lincoln aircraft carrier arriving off Florida late Sunday to help in the southern part of the state and along the Florida Keys.
The National Hurricane Centre said the storm "should continue to lose strength and fall below hurricane intensity" during the day, as it continues its path northwards.
Irma was downgraded to a tropical storm over Florida, but it still had winds near hurricane force. A storm surge warning was discontinued from Flagler and Volusia counties south to Jupiter inlet, but a flash flood warning remains in effect for downtown Jacksonville.
Public schools, state colleges and universities and state government offices have been closed for Monday.
Hurricane Irma made landfall Sunday morning in Cudjoe Key.
