At least 4 people killed in thunderstorms across the South

At least four people were killed and tens of thousands remained without power into Sunday as thunderstorms pounded the southern U.S. throughout the weekend.

About 40 tornadoes were reported between Texas, Louisiana, Mississippi and Alabama, according to the National Weather Service. Meteorologists are working to confirm those reports.

Five tornadoes were reported north and south of Houston, Texas and one person was killed about 30 miles south of the city in Liverpool, authorities said. The victim was identified only as a 48-year-old woman who was found 100 feet from her home. An additional four people were injured in Brazoria County, and more than 40 homes and buildings suffered significant damage.

More than 900 miles east but still part of the same storm system Sunday, a North Carolina man was killed when a tree fell on his car while he was driving, officials said.

Matthew Teeple, 70, was killed while driving his pickup truck in Statesville. A state trooper said Teeple was killed instantly in “a freak accident.”

And two people were killed in Mississippi as the system churned through the state. Tykeria Rogers, 18, was killed when a tree fell on her home in Natchez, Miss., according to NBC News. On the other side of the state, another person was killed in Lowndes County. That person was not identified.

By Sunday night, power had been restored in many places, but 38,000 customers were in the dark in Mississippi and 18,000 people were without power in Louisiana, according to poweroutage.us.

The storm also affected air travel over the busy holiday weekend. On Sunday, more than 400 flights were delayed out of both the Charlotte and Atlanta airports, according to FlightAware. More than 300 flights into both airports were delayed as well.
