Transcript for Reports of Tornadoes in the Northeast
We're going to turn to the severe weather, just as millions hit the road for the memorial day weekend. Hail, tornadoes, damaging winds. And ABC's Reena ninan is in Albany, New York, this morning, where there was a reported tornado. Reporter: Good morning to you. This is an example of how minutes can make a difference with a tornado warning. All that remains is part of the wall here. The grandmother who owns this home, picking up her grandson at the time. And now, even the dogs inside made it out alive. Across the northeast, a flare-up of wild weather. Hail in New York and Pennsylvania. And suspected tornadoes in upstate New York, Delaware and Virginia. Crazy. I didn't think anything could happen like this here. Reporter: This morning, the unbelievable aftermath. The lady saying help her, help her, because her husband was in there and he couldn't get out. Reporter: A look above at Hartley, Delaware, shows four homes and a barn completely destroyed after reports of a twister. And just west of Albany, New York, a possible tornado. Hid behind the wall until it was over. Reporter: And winds so powerful, this semi truck toppled over. This man desperately trying to salvage belongings, ravaged by mother nature. In Virginia, nearly 20,000 people without power. It was terrible. Like, really scary. All hell just broke loose. Reporter: In Pennsylvania, golf ball-sized hail, rocketing through skylights at the Berkshire mall. No one was hurt. The hail leaving Pennsylvania looking like siberia. Okay. We've got a cracked windshield. It looks like we're going to declare an emergency. Reporter: And a crack in the windshield of this U.S. Airway flight, which landed safely after passing through a storm into Philadelphia international airport. Trouble out west, too. Take a look at this funnel cloud, jaw-droppingly close to a flight leaving Denver. The national weather service will be here this afternoon, looking at the debris, to determine if this was a tornado. Residents say if they confirm it, it will be the second one in two years.
