good evening. it was an incredible sight, in part because we could see it live from a helicopter, we watched as tornadoes swept across a huge metropolitan area. dallas/ft. worth in broad daylight in early april. we now know 13 tornadoes touched down. the wind speeds at times reaching 150 miles per hour. the twisters sent 6.3 million people into shelter. and it s now easy to see why. lester holt is heading up coverage from a texas suborn recovering from an f-3 tornado. we re in forney, texas, one of many dallas suburbs hit hard. when i come upon these scenes and i have come upon a lot this spring, if thirst thought is you want to recoil from shock. then you hear the back story, a 61-year-old woman who survived. survival is the headline of the storms thankfully because of a rel thought out and well executed warning system that got people to cover in time. that s right in that neighborhood. they knew they were coming. but even with plenty of warning oh, my goodness.
