The tornado looks to have gone right over three schools as well as a movie theater. The tornado, preliminarily rated as an EF-4 on the Enhanced Fujita scale (meaning it had winds between 166 and 200 mph), carved a trail as much as 2 miles wide and 22 miles long, officials said.

Inside First Baptist Church in Moore, the emotion is still very raw -- some of the people seeking shelter there are just sitting and crying, says CNN's Katie Glaeser, who was shown around by a volunteer this morning.
Food, beds and portable toilets are being supplied, and two large-screen TVs are playing the local news, she added.

The National Weather Service notes that a tornado watch for parts of southern Oklahoma does not include the Oklahoma City area.
A large portion of the country still is under threat of severe weather Tuesday, from the same storm system behind Monday's twister and several others on Sunday. In the bull's-eye Tuesday are parts of north-central Texas, southeastern Oklahoma, and northern Arkansas and Louisiana, according to the weather service.

More details about yesterday's erroneous death toll from officials: Communications problems, including limited cell phone coverage after the storm, might have contributed, Amy Elliott of the Oklahoma Medical Examiner's Office said moments ago.

We have a new death toll -- lower than before: 24 people have died as a result of Monday's storm, nine of whom were children, according to Amy Elliott of the Oklahoma Medical Examiner's Office.
Previously, the office reported that 51 people had died. Elliott said some of those might have been double-counted.
Seven of the nine dead children were recovered from a school, Elliott said. Many of the victims have been identified and their remains are being returned to their loved ones, she said.

More from state Rep. Mark McBride, who represents Moore: "If you didn't have a storm shelter, you didn't ride it through," because the tornado left little place above ground to hide.
"There was no closet to get into, because there was no closet left," he told CNN's Chris Cuomo of the tornado that hit Moore on Monday.

State Rep. Mark McBride, who represents Moore, told CNN he was "just choking back tears, trying to be strong" while he was with rescue and recovery teams yesterday.
"My family has lived in Moore since the 1940s, and we've been through several tornadoes and this is the worst I've seen," he told CNN's Chris Cuomo.
His family is OK. He said his home did not have a shelter and he was now reconsidering that. And he said he was expecting legislation to mandate that schools have shelters.
"People think they can dodge the bullet -- it's hit and miss," he said.
