We'll move on to the latest from the disaster zone in oklahoma. We have stunning new video of the deadly twister as it touched down at an elementary school. A teacher there captured the terrifying seconds on her cell phone. Abc's cecilia vega has more now from moore, oklahoma. Cecil cecilia? Reporter: Amy, good morning. It's hard to imagine what it must have been like for these children huddled down in this school, this tornado fearing down everything around them. Out here, the smell of gas is still thick in this area and this damage, just take a look. It could top more than $2 billion. Reporter: You can't see it but you can hear it. Terror in the darkness, just as the massive ef-5 twister is tearing through briarwood elementary. Oh, my god. Oh, my god. Reporter: This brave teacher capturing the moments of impact on her cell phone. Listen as she tries to comfort her students clinging to each other in a darkened bathroom. It's almost over. It's almost over. I hate this. Honey, it's okay. Reporter: And then it's over. Oh, my god. Oh, my god. Oh, my god, my house. Oh, my god. Oh, my god. Reporter: Across town, walls crumbled around the 22 people riding out the storm in this bank, huddled inside the vault. They were holding the door shut, but when the pressure started to drop and our ears started to pop, that's when the bank manager started yelling don't let go. Reporter: That fifth grade teacher took abc's david muir back to where she and her students had huddled together. This is where we locked down and I was right here with -- there were probably 20, 25 girls in here and several teachers. That's our playground. Reporter: This is the playground here. This is the playground. Reporter: Once the tornado passed, dietsic now worried about two other children, her own. Sam and first grade and her daughter in fourth eventually finding both safe along with her husband. Honey, it's okay. Reporter: This morning residents like tyler kerry back home for the first time to assess the damage wonder what the next step is. You see this and what goes through your mind? First thought, where do you begin. Reporter: He'll start by saving what little they can find in the rubble. Tyler. Reporter: What they found was a blanket tyler's grandmother made for him. You can see and hear these thunderstorms, the rain hamp hampering for those residents going back into their homes. Between 12,000 and 13,000 people's homes impacted by this tornado. The number of people left homeless by this is still unknown and, amy, the white house says that the president will be paying a visit to moore, oklahoma, this coming sunday. And, so sole ya, those were such harrowing moments that we just witnessed and yet speaking to the strength and the spirit of the people there in moore, oklahoma, I understand they're already discussing rebuilding plans. Reporter: That is something almost every single resident that we've met out here tells us that they want to rebuild. This is a community used to living with these tornadoes. Nothing ever like this before but the sense of resolve, the spirit to rebuild is out here but really it's first things first and that begins with restoring power and that's what's happening in these neighborhoods starting today. So much to do, but certainly our hearts go out to everyone there. Cecilia vega, thank you very
