The National Weather Service says eight confirmed tornadoes tore through Louisiana and Texas Wednesday and Thursday.

According to the Governor's Office of Homeland Security and Emergency Preparedness, damage from the eighth tornado hasn't been surveyed yet. Officials say six of the eight developed from the same "parent supercell" over a 150-mile track.

"The survey of the tornado SE of Marion in Union Parish is still ongoing," officials said. "Additional surveys are likely over the next few days."

A total of five people were killed in the tornadoes, two in Louisiana and three in Texas. A mother and her son died in Ruston after a suspected EF3 tornado ripped through the city and downed a tree on their home.

Emergency officials are still distributing supplies to victims and surveying the damage.
