GRANBURY, TEXAS (CBS News) - Residents of a North Texas town ravaged by a deadly tornado are starting to return to home for the first time since the midweek storm.
The process is slow because several hundred people showed up early Saturday to register at a Granbury church. The registration is required to return to the neighborhood.
Only residents of Rancho Brazos Estates and a few friends and relatives are being permitted into the area.
Granbury bore the brunt of an outbreak Wednesday night of 16 tornadoes that swept through North Texas. Six people were killed and dozens injured in the town about 40 miles southwest of Fort Worth.
Texas Department of Public Safety spokesman Lonny Haschel says cars must pass through a three-lane checkpoint to enter the area.
CBS News correspondent Anna Werner reports from Granbury that a string of tornadoes came through North Texas Friday night about 100 miles northwest from Granbury. A stormchaser on the ground shot video of a tornado that touched down near Newcastle, Texas, but no one was hurt.
In Granbury, workers are trying to restore water service, raise electrical lines and clear debris piles filled with insulation, roof tiles, pieces of carpet, a shoe, a teddy bear, a woman's purse.
Jerry Shuttlesworth wasn't planning to return to the neighborhood Saturday. He doesn't know where his mobile home ended up, but he finally has his only treasured possession: his bull-terrier mix, Junior, who had been.
Shuttlesworth, 53, broke three bones in one of his feet and suffered a 2-inch gash in his forehead.
Friends helped spread the word about his dog through social media. On Friday, someone found Junior and took him to a shelter, where a worker called Shuttlesworth.
"You could call it a miracle," he said. "He's scratched up and a little traumatized, but he's eating. He's my baby. I don't care about anything else."
Gov. Rick Perry and Texas Attorney General Greg Abbott on Friday toured Granbury.
Perry said the devastation is almost incomprehensible. Abbott urged residents to be cautious of those who might try to scam them as they rebuild.
The National Weather Service said Friday that the Granbury tornado was an EF-4, based on the Fujita tornado damage scale. Winds in an EF-4 tornado are between 166 and 200 mph. An EF-5 is the most severe.
Also Friday, the Hood County Sheriff's Office said the death toll is unlikely to change, as those who were reported missing were with relatives or friends and are safe.
Workers on Friday cleared debris in nearby Cleburne, where a tornado cut a mile-wide path through part of the city Wednesday and damaged about 600 homes. The weather service said it was an EF-3, which has winds between 136 and 165 mph. No deaths or severe injuries were reported.
