As Colby Hall wrote on Twitter, “I fear the story from a devestated Oklahoma City is going to be [too] big to fathom.” We’re going to see a lot of awful images, and living in the Midwest, there is nothing more frightening than watching the funnel clouds drop and expand we see here in live CBS News coverage:One elementary school in Moore, Oklahoma took a direct hit from the tornado:

Authorities say an elementary school in an Oklahoma City suburb took a direct hit from a mile-wide tornado.

Gary Knight with the Oklahoma City Police Department says there is no word of injuries from the elementary school. Knight says the school suffered “extensive damage” on Monday afternoon.

Moore actually had almost exactly the same thing happen in 1999, in a storm that had the highest winds ever recorded on the surface of the Earth. At one point, the National Weather Service warned that the tornado approaching Moore, Oklahoma would be so large that people on the ground might not even recognize it as one:

The National Weather Service is cautioning that the tornado passing through Moore is so large that people may not recognize it as a twister.

Forecasters urgently warned people in Moore on Monday afternoon to seek immediate shelter.

Colin Schultz tweeted out a picture of the massive damage to Moore:
