YAZOO CITY, Miss. – Rescuers spread out Sunday to find anyone who might be left behind in the rural Mississippi countryside hit hard by a tornado that killed 10 people a day earlier, while others returned to demolished homes to salvage what they could and bulldoze the rubble.

About 40 National Guard soldiers patrolled the devastated Yazoo City, some in Humvees and others in a Blackhawk helicopter. Dozens of volunteer state troopers and other law enforcement officers also came from far-flung parts of the state to help.

The high winds on Saturday ripped roofs off buildings in Yazoo County, a county of about 28,000 people known for blues, catfish and cotton where Gov. Haley Barbour grew up. He described "utter obliteration" among the picturesque hills rising from the flat Mississippi Delta.

"This tornado was enormous," Barbour told The Associated Press as searchers resumed their work.

He said there are about 100 homes in Yazoo County and another 38 in Choctaw County that are uninhabitable. State emergency officials are still trying to determine how many people have been left homeless after Saturday's storm, he said. It's unlikely the final tally of damage and other figures will be done before Tuesda
