The massive storm system that killed several people from Texas to MS is now barreling east, threatening to spawn tornadoes and other catastrophic weather from New England to the Gulf Coast.

The National Weather Service detected a possible twister on radar, but it's unclear whether a tornado or straight-line winds caused the damage.

A MS man, identified as 95-year-old Roy Ratliff died on Saturday when a tornado caused a tree to fall onto his home, Monroe County Coroner Alan Gurley said. No injuries have been reported, but officials said several businesses and vehicles were damaged.

According to the National Weather Service, Sunday is the best setup for potential severe weather that we have had so far this season.

The children, ages 3 and 8, were killed when a tree fell on a vehicle. Franklin is about 125 miles (200 kilometres) south of Dallas.

A tornado was reported in the area 140 miles (225 kilometres) southwest of Memphis, Tenn., at the time. Two people were hospitalized for injuries that were not thought to be life-threatening, while others were treated at the scene, Yezak said.

A preliminary damage survey showed an EF-3 tornado, with winds up to 140 miles per hour, touched down in Robertson County, the NWS in Fort Worth said. Mobile homes will be damaged or destroyed.

Tornado watches are already in place across parts of the region and the potent storm system has already been producing strong tornadoes in eastern Texas. Some people had to be extricated from their damaged dwellings.

While the threat of tornadoes will be lower by then, damaging winds could still bring perilous conditions.

University spokesman Sid Salter said some debris, possibly carried by the tornado, was found on campus, but no injuries were reported and no buildings were damaged. CNN affiliate KWTX reported widespread damage there, including uprooted trees and roofs ripped off buildings.

The large storm system also knocked out power to thousands and caused some flash flooding.

In another storm death nearby, an unidentified victim's body was trapped in a vehicle submerged in floodwaters in Calhoun, Louisiana, Springfield said. Capt. David Agee of the Jefferson County Sheriff's Office says the worker was struck about 2:15 a.m. Sunday near in the Birmingham suburb of Hueytown and died after being taken to a hospital. His name was not immediately released.

The storms are expected to move through the Augusta area during the afternoon and evening.

At Georgia's Augusta National Golf Club, organizers of The Masters golf tournament moved up tee times Sunday to try to beat risky weather.
