I was with my son in Chico, California. It was a clear sunny day, and we were walking down a street. Several blocks away behind me were a row of condominiums. I glanced back and saw about four or five cars suddenly lifted off the ground from behind the building and flung unto the back side of the roof. I stared in shock. I then heard powerful gusts of wind blowing from the southwest to the northeast. About a block away in front of us was a church building covered with metal siding. The wind blew towards the building, and it imploded and crumpled as an aluminum can. I knew there were people inside, and I felt concern and compassion for them.
