Man found dead in tornado-leveled home in North Carolina
A man was found dead in his home Thursday morning after a tornado tore through overnight, according to the fire chief in Rock Ridge, North Carolina.
"The tornado had completely leveled the house. ... We were initially unable to locate the victim," Fire Chief Walt Williamson said. "We called in the FEMA rescue team, which brought in a canine unit to help us find and locate the individual."
"The victim was likely asleep in his bedroom when the tornado struck," Williamson said.
"This was an incredibly challenging task, both logistically and emotionally. It's a lot of destruction to witness," he said.
The tornado also caused major damage to a school in the area, Williamson said.
"The school's roof was torn off," Williamson said. "Thankfully, this happened in the middle of the night when no one was there. If it had been during school hours, it could have been much worse."

Curfew lifted in Charleston
A city-wide curfew was lifted Wednesday morning in flood-prone Charleston, South Carolina.
No rescues were needed due to the curfew, Mayor William Cogswell said.
"After assessing overnight conditions, officials have determined that it is safe to return to normal activities," the mayor said in a statement, but he added that the ongoing storm may still lead to downed trees and power lines.
"Several roads remain closed and are barricaded," the mayor said. "Please avoid driving around barricades or entering flood waters."
Debby’s winds at 45 mph ahead of expected second landfall Thursday
Tropical Storm Debby’s winds slightly strengthened early Wednesday, rising to about 45 mph, as the storm moved over warm water in the Atlantic about 65 miles from the coast of Charleston, South Carolina.
Debby is expected to remain a tropical storm into Thursday, when it’s forecast to make a second landfall in South Carolina.
The National Hurricane Center said it expects the storm to not strengthen much more, maybe rising up to about 50 mph ahead of that landfall.
The storm is then forecast to continue inland overnight into Friday, with its winds slowing as it travels through North Carolina and into Virginia.
Debby is slowly moving eastward offshore
Tropical Storm Debby is slowly moving eastward offshore the coasts of Georgia and South Carolina.
Debby is moving east at 5 mph while max sustained winds remain at 40mph, with its center currently about 50 miles east of Savannah, Georgia, as of 11 p.m. ET.
Tornado Watch remains in effect across eastern South Carolina and North Carolina, from Myrtle Beach to Morehead City until 1 a.m. ET.
Flood Watches remain in effect from Georgia to Virginia as bands of heavy rain will continue through the night.
Debby will be back over open water tonight and could gain a bit more strength over the next 24 hours, but is forecast to remain at tropical storm intensity.
A second landfall is expected in South Carolina Wednesday evening or early Thursday morning.

More than 90,000 customers without power in Florida
More than 90,000 customers remain without power in Florida, more than 24 hours after Debby tore through the state.
"Restoration is taking longer in areas with flooding and heavy vegetation, as crews must wait for the water to recede and clear through debris before they can restore power," Florida Power & Light said Tuesday morning. "Rest assured, we’ll continue working until everyone who can safely receive power is restored. Avoid these flooded areas and stay away from downed power lines."
Charleston’s curfew extended as city faces flash flood warning
A curfew in Charleston, South Carolina, has been extended to 7 a.m. Wednesday as the flood-prone city braces for potentially life-threatening flooding.

More than 150,000 customers without power, tracker says
More than 150,000 customers were without power early Tuesday in Florida, Georgia and South Carolina, according to PowerOutage.us, a tracker of energy providers.
Florida had the highest number of outages, with more than 116,000, followed by more than 26,000 in George and almost 12,000 in South Carolina.
Debby to bring historic 10-20 inches of rainfall: Forecast
Despite weakening since moving over land, Debby is still maintaining its tropical storm status, producing maximum sustained wind speeds of 45 mph.
As of 11 p.m. ET, over 150,000 customers in Florida and Georgia are still without power, according to PowerOutage.us.
With Debby's center about 35 miles west of Brunswick, Georgia, much of the heavy rain and showers have since moved out of Florida (except for the extreme northeastern corner of the state closer to the Georgia border). However, with the storm slowing down even more, Debby will stay stuck over the Southeast for the better part of this week, meandering over Georgia and the Carolinas.
Even though the storm is expected to weaken a bit more overnight, Debby is still expected to bring historic rainfall and life-threatening flooding to portions of southeastern Georgia and the coastal areas of the Carolinas over the next few days. Rainfall totals from this event are expected to reach between 10 and 20 inches.
Already, portions of southeastern Georgia and South Carolina have seen between 3 to 6 inches of rainfall, but with rainfall rates of 1.5 to 3 inches per hour possible, flood alerts remain in effect.
A Flash Flood Warning was issued for Charleston, South Carolina, where rainfall rates between 1.5 and 2.5 inches are expected. Ongoing or new flooding is expected, with an additional 2 to 4 inches of rain possible over the next few hours.
As onshore flow continues, storm surge remains an issue in Savannah, Georgia, and Charleston, South Carolina. Storm surge alerts remain in effect up the Georgia and Carolina coastlines.
Rainfall aside, Debby could also generate some spin-up tornadoes as it swirls over the Georgia-South Carolina border tonight. As a result, a Tornado Watch also remains in effect for parts of southeastern Georgia and South Carolina until 1 a.m. ET.
Over the next 48 hours, Debby is expected to meander back over the Atlantic but will continue to hug the coastline before heading back inland over the Carolinas again. Slight strengthening can't entirely be ruled out as it moves back over water, but ultimately, Debby is expected to weaken once it moves back inland. Strength aside, it will still bring significant rainfall to portions of the Southeast, which will likely lead to catastrophic flooding in some areas.
Debby is expected to eventually drift toward the north/northeast by the end of the week into the weekend. As it heads north, it will likely weaken to a tropical depression or remnant low. Regardless, heavy rainfall is still expected up the I-95 corridor heading into this weekend.
Power returns to some Florida customers as Debby moves northeast
As of Monday evening, 146,034 customers are without power in Florida, according to the latest update from a U.S. power outage map.
This marks an improvement from Monday morning, which saw nearly 300,000 customers without power at 9:50 a.m. ET, the height of outages across the state.
During a press conference in Tallahassee Monday morning, Gov. Ron DeSantis said the state's emergency department had 17,000 linemen working to restore power in the wake of the storm.
"We have a lot of restoration personnel ready to go," DeSantis said.
Debby weakening, but threats of tornadoes, heavy rain continue
Tropical Storm Debby continues to weaken, with maximum sustained winds down to 45 mph as of 8 p.m. ET. The weather pattern is moving very slowly to the northeast at 6 mph, and the center is currently about 50 miles east of Valdosta, Georgia.
Even though Debby is now inland and continues to weaken, many of the impacts -- especially the heavy rainfall and dangerous flash flood threat -- will not abate for several days. For many locations in coastal Georgia and South Carolina, the worst is yet to come.
The tornado threat continues along portions of the Georgia and South Carolina coasts this evening and into tonight. A Tornado Watch remains in effect from Savannah, Georgia, to Charleston, South Carolina, until at least 1 a.m. ET.
Parts of Florida, including Sarasota and Lakewood Ranch, are reporting over a foot of rain from Debby, and portions of Suwannee County, including Live Oak, are getting around a foot as well.
So far, parts of Georgia, including Savannah, are reporting nearly 4" of rain. The same can be said for Hilton Head, South Carolina.
Conditions will continue to deteriorate across much of South Carolina overnight Monday into Tuesday, with widespread areas of heavy rain and the potential for dangerous, significant flash flooding during nighttime hours.
Coastal flooding and storm surges will continue to increase in the coming hours as winds increase and more persistent heavy rain moves in, heading into high tide along the Georgia and South Carolina coasts.
By late Tuesday afternoon or early evening, the center of Debby will likely be moving off the Southeast coast and into the Atlantic, where it will meander for about 24 hours before likely turning back toward the coast and potentially making another landfall as a tropical storm somewhere along the South Carolina coast by Thursday morning or afternoon.
More than 163,000 customers without power in Florida

The emergency declaration will allow for the state to mobilize resources to respond to the storm.
Tropical Storm Debby slowing down as it moves across US
Tropical Storm Debby continues to weaken and slow down in forward speed as the center moves near the Florida-Georgia state line as of 5 p.m. ET.
Maximum sustained winds are down to 50 mph, and Debby is moving to the northeast at 6 mph. The center is currently about 30 miles southeast of Valdosta, Georgia.
As of Monday afternoon, all tropical weather and storm surge alerts have been canceled across Florida's Gulf Coast as conditions improve across much of the state.
Debby will move across southeastern Georgia through Monday evening, with the worst impacts focused there and into the Jacksonville, Florida, area. Heavy rain continues to overspread southern South Carolina as well.

Storm surge has been rising quickly now along the Big Bend area in Florida, from Cedar Key to Keaton Beach, where up to 10 feet of Gulf water could inundate the coastline. The storm is forecast to make landfall in that area on Monday morning.
Coast Guard rescues two adrift in sailboat off Florida coast
Two people were rescued Sunday from a boat that was adrift in about 20-foot seas off the coast of Boca Grande, Florida, the U.S. Coast Guard said.
The boaters were airlifted from their 34-foot sailboat after the vessel lost its sail about 73 miles off shore, the guard said.
The sailboat had been on course for Tarpon Springs from Key West, officials said. A friend of the boaters contacted the Coast Guard at about 5 p.m. Saturday, telling officials they had missed their check-in.
"We received an updated satellite position from the boaters' friend, which led to them being successfully located," Lt. Cmdr. Christopher Hooper, a search and rescue mission coordinator, said in a statement.
The boaters were rescued by a crew on an Air Station Clearwater MH-60 Jayhawk helicopter at about 11 a.m. on Sunday, the Coast Guard said. They had been adrift in seas that were between 15 and 20 feet, with wind speeds at about 50 knots. Visibility was low.
The names of the people on the boat were not released.
Debby strengthens into a hurricane
The National Hurricane Center has upgraded Tropical Storm Debby to a Category 1 hurricane with winds of 75 mph.
The forecast is still on track for more strengthening overnight as Debby feeds off the warm water in the eastern Gulf of Mexico. Water temperatures running 3 to 5 degrees above average are providing plenty of fuel for this storm to intensify before landfall, which will happen around 7 a.m. ET along the Big Bend region of Florida.
Tropical Storm Debby nearing hurricane strength at 70 mph
While still a tropical storm, Debby is nearing hurricane strength, producing maximum sustained wind speeds up to 70 mph.
Debby will continue to intensify rapidly overnight as it travels northward over the Gulf's warm waters. It is forecast to become a hurricane tonight. It is expected to strengthen to at least a strong Category 1 hurricane before making landfall along Florida's Big Bend region Monday morning (around 7 a.m. ET), producing sustained wind speeds near 85 mph and wind gusts reaching over 100 mph possible.
Located about 90 miles southwest of Cedar Key, Florida, the storm continues to impact the Florida Gulf Coast with heavy rainfall, storm surge, powerful winds and even spin-up tornadoes.
A reported wind gust of 56 mph was reported in St. Petersburg, with two tornadoes reported in central Florida.
A 60-mph wind gust was also reported near Sarasota, Florida.
Numerous reports of flooding from heavy rainfall and surges have also been submitted up Florida's Gulf Coast.
The Tornado Watch covering much of northern and central Florida and southern Georgia has been extended until 6 a.m. ET on Monday.
Once Debby moves over land, it will weaken. However, the lack of a steering current will cause the storm to slow down considerably. While its exact track remains questionable, model guidance suggests the storm will drift over the Atlantic or Southeast coastline late Monday night into Tuesday before meandering back over Georgia and the Carolinas. Interaction with the Atlantic could reenergize Debby, but that will greatly depend on the storm's path.
Even though Debby's track and timing remain uncertain later this week, there is high confidence that it will bring historic rainfall and significant flooding across portions of the Southeast.
Rainfall ranging between 6 to 12 inches is possible from Florida's Big Bend region through southeastern Georgia and into the Carolinas. Parts of coastal Georgia and South Carolina will be in the bullseye for the heaviest rainfall. There, widespread totals between 10 to 20 inches are possible, with some places even seeing up to 30 inches locally. Because of this, significant urban and river flooding is anticipated.
Rainfall aside, hurricane and tropical storm force winds will continue to whip across Florida and will likely intensify Sunday night into Monday as the storm moves closer to the coast -- with areas just south and east of the storm's eyewall seeing the strongest gusts early Monday morning.
Storm surge will also worsen along Florida's northern and central Gulf coast tonight into Monday morning, with the highest surge expected between Suwannee River and Ochlockonee River (6 to 10 feet).
All tropical alerts remain unchanged from the last update.
Tropical Storm Debby on track to become a hurricane overnight
As of 5 p.m. ET on Sunday, Tropical Storm Debby still has winds of 65 mph and is forecast to undergo rapid intensification into a hurricane overnight, according to the National Hurricane Center.
Debby is expected to make landfall as a hurricane in Florida’s Big Bend region on Monday morning around 7 a.m.
Rain is expected to be the most impactful element from this storm, affecting a wide area over an extended period of time.
"Across portions of southeast Georgia and South Carolina, 10 to 20 inches of rainfall, with local amounts to 30 inches, are expected through Friday morning," the National Hurricane Center said. "This potentially historic rainfall will likely result in areas of catastrophic flooding."
Evacuations ordered in Alachua County, Florida, as Debby set to make landfall
An evacuation order was issued Sunday for residents of Alachua County, Florida, residing in mobile homes, manufactured homes and recreational vehicles ahead of the arrival of Debby, which is forecast to be a hurricane when it makes landfall on Monday.
People living in areas close to rivers and lakes, and low-lying areas that tend to flood in Alachua County are also encouraged to evacuate, according to a statement issued by county officials.
Gainesville is the largest city in Alachua County.
"We encourage residents affected to find alternative housing with friends, family or short-term rentals," according to the county's statement.
Alachua County is opening three shelters for residents in need.
Tornado watch issued as Debby runs parallel to Florida's Gulf Coast
A tornado watch was issued Sunday afternoon by the National Weather Service as Tropical Storm Debbie moved northward in the Gulf of Mexico parallel to Florida's Gulf Coast.
At 2 p.m. Sunday, the National Hurricane Center said Debby was still a tropical storm with winds of 65 mph and forecasted to bring severe weather, including heavy rain, to coastal communities Sunday afternoon.
A tornado watch is in effect for much of Florida through Sunday evening.
Debby is expected to become a hurricane Sunday evening and will likely make landfall sometime between 7 a.m. and 8 a.m. Monday in the Big Bend area of Florida's Panhandle.
Once Debby makes landfall, the storm is expected to slow down and essentially stall over the Southeast, dropping potentially historic amounts of rainfall as it moves into Georgia and South Carolina.
A hurricane warning is in effect for the west coast of Florida from the Ochlockonee River southwest of Tallahassee to the Suwannee River northwest of Gainesville.
More than 1,600 flights canceled due to Debby and Northeast thunderstorms
Tropical Storm Debby and thunderstorms in the Northeast were causing airlines to cancel or delay flights on Sunday.
American Airlines said it canceled 601 flights, or about 16% of its flights, on Sunday, the most of any airline.
Debby, now a tropical storm in the Gulf of Mexico, is expected to make landfall around the Big Bend area of the Florida Panhandle on Monday morning as a Category 1 hurricane.
Also causing delays and cancellations were severe thunderstorms moving up the East Coast. Parts of the mid-Atlantic states are under a severe thunderstorm watch until 9 p.m. ET Sunday, including the cities of Washington, D.C., Baltimore, Philadelphia, and New York City.

Ten million people under tropical storm alert on Florida's Gulf Coast
About 10 million people along Florida's west coast and up through Georgia and South and North Carolina were under a tropical storm alert Sunday as Debby took aim at the area and is forecast to make landfall in the Panhandle region on Monday.
Debby, now a tropical storm in the Gulf of Mexico about 190 miles southwest of Tampa, is expected to make landfall sometime between 7 and 8 a.m. in Big Bend on the Florida Panhandle as a Category 1 hurricane, state emergency officials said.
Debby is expected to create a storm surge of 4 to 7 feet in Cedar Key and Crystal River on the Florida west coast and a 2- to 5-foot storm surge farther south in Tampa and Sarasota.
The storm is forecast to move into the cities of Tallahassee and Jacksonville, bringing up to 20 inches of rain to some parts, before causing potential flooding in Georgia and the Carolinas on Tuesday, Wednesday and Thursday.
National Guard put on alert for search and rescue: DeSantis
Members of the Florida National Guard have been advised to be prepared to conduct search-and-rescue missions once Tropical Storm Debby makes landfall on Monday, according to Florida Gov. Ron DeSantis.
Widespread flooding is expected for the Florida Panhandle region, particularly in the Big Bend area where Debby is expected to make landfall Monday morning as a category 1 hurricane, DeSantis said during a news conference Sunday morning.
DeSantis said the Florida National Guard and the state's Emergency Response Team are prepared to conduct search-and-rescue and provide humanitarian assistance.
"The Florida National Guard is standing by with 3,000 service members ready to assist the state Emergency Response Team, which includes search-and-rescue, route clearance, commodity distribution and protection of critical infrastructure," DeSantis said.
The governor said at least 12 swift boat crews and flat-bottom jon boat crews are also standing by to help with rescues.
He said that more than 30,000 bottles of water, more than 160,000 meals and nearly 14,000 tarps have been pre-staged in parts of Florida that are expected to be hit hard by the storm.
DeSantis said Florida utility companies have notified up to 17,000 linemen to be ready to spring into action once it is safe to repair any damage.
Flooding forecast as Debby expected to bring up to 20 inches of rain
Florida residents in the Big Bend region of the Panhandle were warned Sunday that Debby is going to bring "catastrophic rain to the area" that will cause flooding and power outages.
Kevin Guthrie, director of the Florida Division of Emergency Management, said during a news conference on Sunday that once the Debby makes landfall as a possible Category 1 hurricane on Monday morning, winds will subside quickly, but the slow-moving storm will produce an abundance of rain.
"We're going to be in a catastrophic rain situation where we have situations in Florida that will receive 15, maybe as high as 20 inches of rain," Guthrie said.
Florida Gov. Ron DeSantis told residents who are in the path of the storm to expect widespread power outages.
"It's possible that you could have serious intensification between now and landfall. It could get up to 85, 90 and 95 mph sustained winds. That is absolutely possible, particularly in parts of the state like here in Tallahassee. There's going to be a lot of trees that are going to fall down and you're going to have debris. You are going to have power interruptions," the governor said.
Gov. DeSantis advises residents to make final preparations for Debby
Florida Gov. Ron DeSantis advised residents of the state's Panhandle region on Sunday that they should be finalizing preparations for when Tropical Storm Debby makes its anticipated landfall Monday morning as a Category 1 hurricane.
"Now this is a storm that is potentially dangerous. Residents should be finalizing all of their preparations now," DeSantis said during a news conference at the state's Emergency Operation Center in Tallahassee.
DeSantis said Tropical Storm Debby was in the Gulf of Mexico about 190 miles southwest of Tampa as of Sunday morning with sustained winds of about 50 mph.
"But those are expected to increase," DeSantis said. "Tropical Storm Debby is likely to become a Category 1 hurricane before making landfall in the Big Bend region of Florida."
He said the storm was on a similar track taken by Hurricane Idalia in 2023. Idalia made landfall in Big Bend on Aug. 30, 2023, as a Category 3 hurricane and caused a devastating storm surge of 7 to 12 feet across the coastal Big Bend region in Levy, Dixie and Taylor counties.
"This storm is a similar track," DeSantis said. "It may be a tick to the west of that. It very well may have greater impacts here in the Tallahassee region than Hurricane Idalia did. Once it crosses landfall and enters the Florida Panhandle/Big Bend Region, wherever it does, it's going to move very slowly across northern Florida and southeast Georgia."
