"I saw that my sunroom was blowing off of its foundation, off the house," Justin Macksoud told FOX2. "It was in half, it had an upper half and a lower half. Almost like a mouth, chomping up and down. And when it went up one final time, I noticed there was a tree laying there. I looked in the backyard and my oak and my maple had knocked each other and left giant holes in the concrete."
