We have had tornados up in the area of the San Jac in Moreno Valley. One tornado flipped an 18 wheeler over and left it laying on it's side blocking all lanes on the 215 South just South of the 215/60 freeways in the Moreno Valley area. It also flipped a bunch of boxcars off the tracks next to the freeway.
