2 dead, others injured as storms roll through South

Millions of people from across the South are under threat of damaging winds, strong tornadoes and hail Saturday as the region braces for more potential destructive storms.

Multiple tornadoes have been reported in Texas, Louisiana, Alabama and Mississippi over the past couple of days, including an EF1 tornado (86- to 110-mph winds) near Fullerton, Louisiana, on Friday.

The National Weather Service confirmed five tornadoes in Texas on Thursday, including an EF1 in the Houston area that caused structural damage to some homes.

The storm threat was renewed Saturday, with a risk for tornadoes, destructive winds and hail into the overnight hours as the line of storms pushes east. Localized flash flooding was also possible.

One person was killed and four others had non-critical injuries in a tornado in Brazoria County, the sheriff's office said Saturday. The office did not provide further details on the death or the victim's identity.

In Mississippi, one person died in the city of Natchez, Malary White from the Mississippi Emergency Management Agency said Saturday. The circumstances surrounding the death are unclear but it was related to storms in the area.

The Chambers County Sheriff's Office in Texas said Highway 124 will be closed for a day or two due to downed power lines and other damage from tornadoes.

Another tornado in east Montgomery County caused "extensive damage," including to a fire station, but no fatalities and only minor injuries were reported, said Jason Smith, deputy chief of staff in County Judge Mark J. Keough's office.

The East Montgomery County Fire Department confirmed its station sustained damage from the twister.

"Despite the challenges, we remain fully operational and committed to serving our community," the fire department said in a statement Saturday. The statement added that the fire house has power from a generator.

By Sunday, this line of storms will march east, with a slight risk for severe weather impacting an additional 24 million people from east Alabama to Virginia. Atlanta, Charlotte, and Raleigh are included in this risk for more tornadoes, damaging wind gusts and large hail.

Amid the ongoing weather, there have been more than 9,500 flight delays and 452 cancellations within, into or out of the U.S. as of 10:30 p.m. ET Saturday, according to FlightAware.com.

The majority of delays are into and out of Dallas-Fort Worth International Airport, which had more than 1,110, according to FlightAware. Houston's George Bush Intercontinental Airport had the most flight cancellations into and out of the airport — a total of 151 as of Saturday night.
