After making landfall a second time, Tropical Storm Debby on Thursday further inundated the rain-soaked Carolinas as well as parts of Virginia, worsening widespread flooding, and spawning a deadly tornado as the Northeast braces for the system's arrival.

Debby made its second U.S. landfall around 2 a.m. near Bulls Bay, South Carolina, just northeast of Charleston, according to the National Hurricane Center. In a matter of hours, over half a foot of rain had fallen in parts of central North Carolina, causing "life threatening flash flooding" as waterways crested, turning roads into rivers.

Debby is expected to drop 4 to 8 inches of rain − some areas could pick up to 15 inches − across parts of the Carolinas and Virginia on Thursday and Friday, bringing "considerable to locally catastrophic impacts," the weather service's Storm Prediction Center said. All told, rain totals in some parts of South Carolina could exceed 2 feet.

In the days ahead, the storm is forecast to weaken as it picks up speed and moves north, dumping up to 6 inches of rain from Maryland to Vermont. Flood watches throughout the Mid-Atlantic and Northeast regions were set to activate Thursday evening and last through Friday night.

Across Florida, Georgia and South Carolina, Debby has drenched communities in over a foot of rain, breaking several decades-old records. Flash flooding triggered water rescues, overtook roads and breached several dams as winds knocked over trees and tangled power lines. Officials have said at least seven people have died as a result of the storm.

Developments:

∎ Millions of people from southeast Georgia up though the Carolinas and western New York were under flood advisories, according to the National Weather Service. Parts of North Carolina and Virginia, including the cities of Wakefield and Virginia Beach, were under tornado watches.

∎ Virginia's Department of Emergency Management warned residents on X to stay aware of possible tornadoes Thursday and Friday. "Tropical Storm Debby has the potential to create tornadoes, with the threat potentially lasting through the overnight hours," the post said.

∎ In Florida, cleanup crews have cleared over 245 miles of road and eight acres of debris across the state, according to the Florida Division of Emergency Management. Emergency responders in high-water vehicles and on foot rescued at least 120 people trapped by floodwaters.

Over 150,000 in the dark; Duke Energy scrambles to fix outages in NC

From Florida to Virginia, over 150,000 homes and businesses were without power Thursday afternoon, according to USA TODAY's Power Outage Tracker.

The majority of outages – over 134,000 – were reported in North Carolina, which has been pummeled by Debby’s most intense conditions since the tropical storm made landfall around 2 a.m. Thursday. The largest utility provider in the state, Duke Energy, reported 111,534 outages as of noon. On Wednesday, Duke Energy said it had 7,500 linemen and other employees staged across the Carolinas to respond to power outages.

South Carolina reported over 8,800 outages and Virginia had over 6,200, according to PowerOutage.us.

More than 7,000 utility customers across northern Florida’s Big Bend region, where Debby made its first U.S. landfall on Monday, were still in the dark after four days. Since Wednesday, North Florida and other parts of the South were baked by a heat wave that raised temperatures into the high 90s and heat index levels into the triple digits.

Forecasters eye another system in the Atlantic

Just as Debby continues to pound the East Coast, forecasters at the National Hurricane Center on Thursday are also keeping an eye on a developing system near the islands of the Caribbean.

"An area of low pressure could form in the central or western tropical Atlantic Ocean early next week," the center said in an online forecast released Thursday morning. "Some development of this system is possible while it approaches the Lesser Antilles during the early to middle part of next week and moves generally west-northwestward toward the Greater Antilles thereafter."

The system has a 30% chance of becoming a tropical depression or named storm within the next week. The next named on the 2024 storm list is Ernesto.

It's far too soon to determine whether the system will have any impact on any land areas, including the U.S.

North Carolina resident prepared campground for Debby

In Raeford, North Carolina, Michelle Morville said her property got a few inches of rain overnight but hasn’t flooded or lost power.

“It poured and is still raining here with more to come,” Morville told USA TODAY Thursday morning.

Her campground, Idlewild Farm Stays, is terraced to allow for erosion control so that there’s no standing water, Morville said. Rain flows properly down a main driveway during storms, and after the current downpour passes, Morville will use a land plane on the road to clear any remaining moisture, she said.

Many people who come to the farm are visiting family members serving in the military on nearby Fort Liberty, formerly Fort Bragg, Morville said. This week, Morville is offering discounted rates to anyone needing to move their camper or RV out of a flood zone, she said.

“Most flooding issues I believe come from a lack of regard for Mother Nature and not planning accordingly to work with her,” Morville said.

Where is Tropical Storm Debby?

Tropical Storm Debby gained speed but lost intensity as it moved farther inland on Thursday, hours after making its second U.S. landfall, the National Hurricane Center said.

According to an 11 a.m. update, the storm was moving north-northwest at 10 mph, twice as fast as when it was recorded several hours earlier. Debby was located 80 miles southeast of Charlotte and 110 miles southwest of Raleigh, with sustained winds of 40 mph, down from 50 mph at 8 a.m., according to the center.

Debby is forecast to continue weakening over the next day, becoming a tropical depression by as early as Thursday afternoon before merging with a front on Friday and being downgraded to a extratropical cyclone.

On Friday, Debby is expected to move across the Mid-Atlantic and Northeast regions before emerging over Canada on Saturday, according to the hurricane center.

Death toll rises to at least 7 after tornado kills man in North Carolina

A man in Wilson County, North Carolina, was found dead in his home after a tornado touched down in the area, bringing the death toll of Tropical Storm Debby to at least seven.

Stephen Mann, director of communication for Wilson County, told USA TODAY on Thursday that a twister tore though the outskirts of Lucama, a town 35 miles southeast of Raleigh, sometime before 3 a.m. A middle school, a church and four homes received structural damage. Inside one of the homes, a search and rescue team discovered the body of an adult male, Mann said.

Officials have tied Debby to at least six other deaths in Georgia and Florida. In the southern Georgia city of Moultrie, a tree fell onto a home, killing a 19-year-old, Gov. Brian Kemp said Tuesday. In Florida, two adults and one teenager were killed in fatal accidents; a 13-year-old boy died after a fallen tree landed on a mobile home; and officials on Tuesday found the body of a boater who had been missing near the city of Gulfport.

Early Thursday morning, officials confirmed a tornado touched down in North Carolina's Sampson County, damaging two homes, according to weather service reports. A suspected tornado was also reported in Pender County. Across South Carolina and Florida, Debby spawned eight tornadoes earlier this week.

Reopening begins after flooding cuts off North Carolina town

Authorities in Bladenboro, North Carolina, began reopening several main roads after the town was completely cut off by floodwaters overnight.

"Water has receded in some areas. Crews will begin reopening up roads here shortly," said a statement on the county's Facebook page. Much of the downtown was still closed as standing water remained several inches deep in some areas.

Just before midnight, as Debby approached the South Carolina coast, a statement on the Bladenboro town Facebook page announced "Downtown is underwater. We have several street closures out. Please stay off the roads!" Within an hour, the local fire department made an announcement, saying "Due to flooded roadways all roads into Bladenboro are closed."

As the heavy rains and tornado threat shifted away from the area toward more northern parts of North Carolina and Virginia, the town has begun to assess the damage and reopen main roads. "Many secondary roads have not been checked, use caution," the fire department warned early Thursday.
