Hospital emergency department manager Nick Stremble didn't need the television to tell him the tornado would hit Moore Medical Center. All he had to do was look outside the window. "There's a big window area that faces southwest," Stremble said, recalling his final check before heading to the safe area on the first floor of the hospital in Moore, Okla., about 10 miles from Oklahoma City. "I could see the tornado in the neighborhood across the street from us. I could see the debris. It was more than obvious it was going to be there in under a minute."
