TO put things in perspective, if Irma went up the Channel then the wind would be so strong most buildings in london and Paris would collapse. The office building will most stand, but veyr damaged. Peoples houses wold just be flattened.
People don;t tend to realize but the energy in wind is cubic in the windspeed. Windows of 60MPH will blow roofs off houses. 8-MPH will flatten some exposed buildings.
Irma has had peak sustained winds of 185MPH, gusts over 225MPH. There is no surviving those kinds of conditions.
