Hurricane Irma has caused catastrophic damage in Barbuda, St. Barthelemy, St Martin, Anguilla and the Virgin Islands as a Category 5 hurricane with winds of 185 mph. Anything over 157 mph is classified as a Category 5 hurricane. There is no such thing as a Category 6. Mountainous waves are expected to lash the coasts and destroy all the houses they hit. Americans are stocking up on food frantically as 2.7 million properties are threatened with destruction in Florida.
