MIAMI -- Residents were allowed to return Tuesday to some islands in the Hurricane Irma as officials pieced together the scope of the storm's destruction and aid rushed into the drenched and debris-strewn state.hit by
It has been difficult to get detailed information on the condition of island chain where Hurricane Irma first came ashore over the weekend because communication and access were cut off by the storm's arrival as a Category 4. But displaced residents and business owners from Key Largo, Tavernier and Islamorada near the mainland were allowed to return for their first glimpse of the damage Tuesday morning.
People from the Lower Keys faced a longer wait with a roadblock in place where the highway to farther-away islands was washed out by the storm. Road repairs were promised in the coming days.
County officials said the 42 bridges that span the Keys need to be inspected before all of the Keys can be reopened, CBS News correspondent Mark Strassmann reports.
About half of the bridges were reported safe by Monday evening, but frustrated Floridians were running out of patience and just want to get home.
"I have water, I have food, I have dogs, and I can't get to my house," one homeowner yelled at a Miami-Dade police detective briefing residents.
"This should have been thought out a while ago," another yelled.
Florida Gov. Rick Scott said Tuesday morning that officials are continuing to check the bridges. He said none appear seriously damaged but that "we're not sure that on the bridges we should be putting on significant weight."
After flying over the Keys Monday, Scott described overturned mobile homes, washed-ashore boats and rampant flood damage.
"It's devastating," he said.
A Navy aircraft carrier was due to anchor off Key West to help in search-and-rescue efforts. Drinking water supplies in the Keys were cut off, fuel was running low and all three hospitals in the island chain were shuttered.
Elsewhere, areas such as Tampa Bay had braced for the worst but emerged with what appeared to be only modest damage.
Early Tuesday, the remnants of Irma were blowing through Alabama and Mississippi after drenching Georgia.
Key West resident Laura Keeney was waiting in a Miami hotel until it was safe to return home, and she was anxious to hear more about her apartment complex. Her building manager told her there was flooding there, but further updates were hard to come by because power and cell phone service have been down on the island.
"They told me there is definitely water in the downstairs apartment, which is me," said Keeney, who works as a concierge at the Hyatt hotel in Key West.
A stunning 13 million Florida residents were without electricity - two-thirds of the state's residents - as sweltering tropical heat returned across the peninsula following the storm. In a parting blow to the state, the storm caused record flooding in the Jacksonville area that forced dozens of rescues on Monday. It also caused flooding and outages in Georgia and South Carolina as it moved inland.
School was canceled in communities around Georgia, and more than 1.2 million customers there were without power Tuesday morning.
Six deaths in Florida have been blamed on Irma, along with three in Georgia and two in South Carolina. At least 35 people were killed in the Caribbean.
More than 180,000 people huddled in shelters in Florida, and officials warned it could take weeks for electricity to be restored to everyone.
During its march up Florida's west coast, Irma swamped homes, uprooted trees and flooded streets.
Around the Tampa-St. Petersburg area, where Irma rolled through early Monday, damage appeared modest. And the governor said effects on the southwest coast, including in Naples and Fort Myers, was not as bad as feared.
Still, people in that area, like Jeff Pompeo of Naples, took Irma's strongest punch, which included 140 mph wind gusts, CBS News correspondent Jeff Glor reports.
He knows despite the damage in his neighborhood and around Collier County the destruction could have been worse.
"How do you prepare for something like this?" Pompeo asked. "You don't know until it's over, you know what I mean? We're pretty lucky."
Scott predicted that recovery could take a long time in many areas.
"I know for our entire state, especially the Keys, it's going to be a long road," he said.
He said the Navy dispatched the USS Iwo Jima, USS New York and the aircraft carrier Abraham Lincoln to help with relief efforts.
The Keys are linked by 42 bridges that have to be checked for safety before motorists can be allowed in, officials said. County officials placed a roadblock around Mile Marker 74 just before Sea Oates Beach, but said crews were working to restore U.S. 1 as quickly as possible.
In the Jacksonville area, close to the Georgia line, storm surge brought some of the worst flooding ever seen there, with at least 46 people pulled from swamped homes. The Jacksonville Sheriff's Office warned residents along the St. Johns River to evacuate Monday as floodwaters rose.
Paul Johnson and Shonda Brecheen spent Sunday night in a house they're remodeling in the San Marco neighborhood of Jacksonville after working late on a remodeling project. Jonhson woke up Monday morning, looked out the window and saw boats passing by where cars used to drive in the neighborhood near the river.
They managed to push his truck through standing water to a nearby parking lot to dry out, but he's worried about damage to the swamped vehicle.
"I'm 32, I've lived here most of my life, and I've never seen anything like that," he said.
