Authorities across a wide swath of the southeastern United States faced the daunting task on Saturday of cleaning up from Hurricane Helene, one of the most powerful to hit the country, as the death toll continued to rise.
At least 47 deaths were reported, and officials feared still more bodies would be discovered across several states.
Downgraded late on Friday to a post-tropical cyclone, Helene continued to produce heavy rains across several states, sparking life-threatening flooding that threatened to create dam failures that could inundate entire towns.
In Florida’s Pinellas County near Tampa, Sheriff Bob Gualtieri said he had never seen destruction like what was wrought by Helene. “I would just describe it, having spent the last few hours out there, as a war zone,” Mr Gualtieri told a press conference.
At least 3 million customers woke up early on Saturday without power across five states, with authorities warning it could be several days before services were fully restored. The worst outages were in South Carolina with more than 1 million homes and businesses without power, and Georgia with 750,000 without power.
As of 5am the remnants of the storm was about 220km (135 miles) west southwest of Louisville, Kentucky.
Some of the worst rains hit western North Carolina, which saw almost 76cm (30 inches) of precipitation fall on Mount Mitchell in Yancey County, the NWS’s Weather Prediction Center reported.
Atlanta was hit with 33cm of rain, and in South Georgia farmers were assessing the damages to the state’s €895.4 million (($1 billion) cotton crop now in its harvest season.
Scientists say climate change contributes to fuelling stronger, more destructive hurricanes.
Before moving north through Georgia and into Tennessee and the Carolinas, Helene hit Florida’s Big Bend region as a powerful Category 4 hurricane on Thursday night, packing 225k/h (140m/h) winds. It left behind a chaotic landscape of overturned boats in harbours, felled trees, submerged cars and flooded streets.
Police and firefighters carried out thousands of water rescues throughout the affected states on Friday.
More than 50 people were rescued from the roof of a hospital in Unicoi County, Tennessee, about 200km northeast of Knoxville, state officials said, after flood waters swamped the rural community.
Rising waters from the Nolichucky river prevented ambulances and emergency vehicles from evacuating patients and others there, the Unicoi County Emergency Management Agency said on social media. Emergency crews in boats and helicopters were used to conduct rescues.
Elsewhere in Tennessee, Rob Mathis, the mayor of Cocke County, ordered the evacuation of downtown Newport because of a potential failure at the nearby Walters dam.
The National Weather Service issued flash flood warnings overnight for a swath of eastern Tennessee covering 100,000 residents, warning them to seek higher ground. The Nolichucky Dam in Tennessee’s Greene County was on the brink of failure early on Saturday, officials reported, adding that a breach could occur at any time.
On Friday, president Joe Biden added Tennessee to the long list of states under declarations of emergency, which frees up federal funds and other assistance for recovery.
In western North Carolina, Rutherford County emergency officials warned residents near the Lake Lure Dam that it might fail, although they said late on Friday that failure did not appear imminent.
In nearby Buncombe County, landslides forced interstate highways 40 and 26 to close, the county said on X.
The extent of the damage in Florida began emerging after daybreak on Friday.
In coastal Steinhatchee, a storm surge – a wall of seawater pushed ashore by winds – of eight to 2.4-3m moved mobile homes, the National Weather Service said on X. In Treasure Island, a barrier island community in Pinellas County, boats were grounded in front yards.
The city of Tampa posted on X that emergency personnel had completed 78 water rescues of residents and that many roads were impassable because of flooding. The Pasco County sheriff’s office rescued more than 65 people.
Officials had pleaded with residents in Helene’s path to heed evacuation orders, with National Hurricane Center Director Michael Brennan describing the expected storm surge as “unsurvivable”.
Mr Gualtieri, the Pinellas County sheriff, said the conditions prevented first responders from answering several emergency calls. On Friday, county authorities found at least five people dead.
Two others in Florida died, said governor Ron DeSantis. Georgia governor Brian Kemp’s office reported 15 storm-related fatalities in that state, while North Carolina governor Roy Cooper said there had been two deaths there.
At least 19 people died during the storm across South Carolina, the Charleston-based Post and Courier newspaper reported, citing local officials. – Reuters
