Surpassing Quant Think Tank Center|Carolinas bracing for second landfall from Tropical Storm Debby: Live updates

As Tropical Storm Debby strengthened along the Atlantic coast on Surpassing Quant Think Tank CenterWednesday, millions in the Carolinas braced for the system to make a second landfall, further inundating rain-soaked communities and extending widespread flooding through the mid-Atlantic region.

Debby, which forecasters say could be the wettest landfalling hurricane ever, has drenched parts of Florida, Georgia and South Carolina in over a foot of rain. The flash floods forced evacuations, overwhelmed drainage systems and breached multiple dams in Georgia. At least five deaths have been tied to the storm.

After pushing off the coast of Georgia on Tuesday, Debby is projected to strengthen before moving ashore along the central coast of South Carolina Wednesday night or early Thursday morning, according to the National Weather Service. Debby could dump an additional 3 to 9 inches of rainfall − and local amounts could range as high as 25 inches in South Carolina and 15 inches in North Carolina through Friday.

"People should be prepared to seek higher ground and to know of an evacuation route and have a plan in place," AccuWeather Meteorologist Brandon Buckingham said.

On Tuesday, some cities in the Mid-Atlantic began to feel the effects as Debby's tropical moisture interacted with a cold front, spawning early storms. New York City, Philadelphia and Newark were soaked in several inches inches of rain, and there were reports of flooding in low-lying areas.

Later in the week and into the weekend, Debby is expected to gain speed and push through the Northeast, dumping more rain across the region and causing "considerable flash and urban flooding as well as river flooding," according to the weather service.

Developments:

∎At a press conference Wednesday morning, North Carolina Gov. Roy Cooper said the emergency operations center was focusing on preparations for any potentially severe flooding impacts. Steps included activating 17 swift-water rescue teams and staging them along the coast and deploying more than 350 members of the North Carolina National Guard.

∎ Millions of people from southeastern Georgia to eastern Virginia were under flood advisories on Wednesday as forecasters projected more rain for the Carolinas and Northeast and continued flooding along waterways and low-lying areas in Georgia and Florida.

∎ Travel advisories and flood watches were in place across New York City through the morning after a night of heavy rain. "We're not in the clear from this rain yet, New York," said Mayor Eric Adams in a post on X.

North Carolina counties, towns issue voluntary evacuations

Local officials in North Carolina have issued voluntary evacuations order for low-lying and coastal areas as conditions from Tropical Storm Debby began picking up.

Multiple counties and beach communities, including North Carolina's Brunswick County and Oceanisle Beach, near the South Carolina border, have urged residents to evacuate, citing heavy rains and dangerous storm surge.

“Don’t take this storm for granted simply because it is labeled a tropical storm − there will be severe weather impacts throughout the week," said Randy Thompson, chairman of the Brunswick County Board of Commissioners, in a news release.

"Due to the high probability of life-threatening flood waters on the coast and inland over the next few days, visitors should carefully consider evacuating," said a statement posted Wednesday by officials in Oceanisle Beach.

From Folly Beach, South Carolina, to the coasts of North Carolina's Ocracoke Inlet, storm surge from Debby could reach 1-3 feet if it coincides with peak high tide, according to the National Hurricane Center.

Tropical Storm Debby strengthens offshore

Tropical Storm Debby strengthened on Wednesday as it churned northward along the Atlantic coast ahead of an expected landfall in South Carolina.

According to an 11 a.m. update from the hurricane center, Debby's maximum sustained winds reached 60 mph, up from 45 mph at 8 a.m. The storm, located 55 miles southeast of Charleston and 100 miles south of Myrtle Beach, was moving at 5 mph.

The National Hurricane Center, citing Debby's lack of a well-defined core, said the storm's strengthening will be "limited." But while the intensification is not expected to be significant, Debby still poses a major threat to coastal and inland areas across the eastern U.S. where extensive flooding is ongoing.

Debby is worst storm in Georgia resident's recent memory

When Glenn De Vecchis tried to leave his house in east-central Georgia on Wednesday morning after Tropical Storm Debby left the area, the state of the roads left him "really scared." The storm scattered some branches across the roads, and deep puddles in several places blocked his vision.

"When I hit those big, giant puddles, I couldn't see anything," Vecchis, 69, told USA TODAY. "I was lucky I stayed on the road because I was wobbling all over the place."

The storm lashed De Vecchis' home in Metter, around 65 miles west of Savannah, with rain for three days – "morning, noon and night, without stopping," he said. The retired business owner said his house was set up high enough to avoid the floodwaters and sturdy enough to withstand the winds.

The last serious storm to pass through was 15 years ago, he said, but "this is the worst I have seen."

Northeast storms related to Tropical Storm Debby

The heavy rain and severe thunderstorms that walloped the Northeast and Mid-Atlantic on Tuesday were indirectly related to Tropical Storm Debby, meteorologist Rick Otto of the Weather Prediction Center told USA TODAY. And more is on the way, even before the storm moves in later in the week.

Otto said while the main impacts from Debby have been in the Southeast, a plume of moisture from the tropical storm interacted with other weather systems such as a cold front to produce the torrential rain and flooding in cities Tuesday such as New York, Philadelphia and Newark, wreaking travel havoc.

The Storm Prediction Center said there were dozens of reports of severe weather, mainly from strong wind gusts, from Ohio through Pennsylvania and New Jersey on Tuesday.

According to AccuWeather, there will be additional episodes of flooding downpours and severe thunderstorms with strong wind gusts into Wednesday night from portions of the central Appalachians and Mid-Atlantic to New England.

Streets flood, dams breached in Georgia

The record-breaking rainfall from Tropical Storm Debby caused the breach of several dams in northern Georgia and led to evacuations downstream from a vulnerable dam in South Carolina.

On Tuesday morning, local officials in Georgia's Bulloch County, about 50 miles northwest of Savannah, urged residents near or downstream from two man-made dams to leave the area and avoid a nearby highway. The immense flooding led to evacuations in Statesboro, a city of 34,000 in Bulloch County, as well as the closure of over a dozen roads, according to the Bulloch County Public Safety.

Hours after dams at Simmons Pond burst, the dam at Oglesby Pond was breached, according to Bulloch County Public Safety, which warned that rushing water would cross a nearby highway and wash into neighboring ponds and lakes.

Meanwhile, in Colleton County, South Carolina, local officials warned on Tuesday afternoon that the McGrady Dam had "the potential to fail" and issued evacuation notices to residents downstream. Hours later, the county's fire rescue department said there was "substantial flooding in the area of the dam and creek," but that the structure was holding.

Charleston lifts citywide curfew as Debby churns offshore

The city of Charleston on Wednesday lifted a curfew that had been in place since Monday night when Debby first began inundating the state with torrential rain.

"After assessing overnight conditions, officials have determined that it is safe to return to normal activities," the statement said, adding that main thoroughfares in and out of the city have been reopened. "Thanks to the curfew, Charleston Police and Fire Departments did not need to perform any rescues during the (storm)."

On Tuesday, downtown Charleston received 3.56 inches of rain, breaking the previous record of 3.46 that was set in 1992, according to the National Weather Service. Surrounding areas in Charleston County were drenched in up to 10.5 inches of rain since Monday.

"Expect long term river flooding to inhibit recovery efforts at least into next week, possibly beyond," the weather service office in Charleston said on X.

Charleston Mayor William Cogswell said in a statement that the city "will remain vigilant as Debby lingers nearby, but for now we are just grateful for everyone doing their part."

Nearly 40,000 without power in Florida amid heat advisories

Two days after Debby made landfall as a Category 1 hurricane, swaths of northern Florida were still without power as intense heat bakes parts of the southern U.S.

Across the Big Bend region, over 36,000 homes and businesses were in the dark, according to Poweroutage.us. At its peak, more than 250,000 utility customers had no power as the storm's winds knocked over utility poles and uprooted trees.

Heat advisories were active across the Big Bend as well as South Florida, Texas, Louisiana, Alabama and Mississippi. In northern Florida, heat index temperatures were expected to reach 109 degrees, according to the National Weather Service, which urged people to stay out of the sun and seek out air-conditioning.
