Unusual Weather Damage
Sturdy but Sideways
Many small structures are built very strongly, but are either poorly attached to their foundations or utterly unanchored. Then a severe wind hits, and all that good workmanship which went into the building is wasted! This is a great example from the north side of the Haysville/Wichita tornado of 16 May 1991. Although there were parts of one wall and the roof broken away, the structure as a whole fared much better than a brick house on the same lot that experienced F3 damage. However, this scene alone should be rated (at most) weak F1 because there was no anchoring at all of a small, wooden building to its concrete foundation.
