In Hurricane Irene it blew down a tree inmy back yard. It tore down a bunch of lems and tigs in our yard. The rain from Irene made our door expand which made it hard to close. It scared my chickens and they did not lay any eggs. It knocked out our power for two days. At my grandpa's shop we used a generator and blew up a calculator, computer and a surge protector.
