reports of an emergency there. >> i was in claussen, texas, about 60 miles away. and i could feel the explosion. i at least heard it rattle windows. everyone thought it was the approaching thunderstorms that we're anticipating. but when i stepped outside, there were no storms. and the wind really wasn't that strong enough to rattle windows. about 20 minutes later, we learned what it was that caused the windows to rattle. we were on the road to west, texas. got here about 10:30 central time. there were dozens and dozens of first responder vehicles from all over the region here. those are mostly gone now. what is left behind are law enforcement officials, blocking all the intersections leading into the blast zone. they're still protecting that area, not only for search and rescue. but also for the danger of anymore leaking ammonia in this
