It is good to be prepared, but I have little faith in the forecasters. I did a wash this AM because it said sunny all day. It was overcast all morning and JUST cleared up. They do not know what the hurricane will do, they are notoriously unpredictable. If there is 1% chance of a big storm, that is ALL they will talk about for days.
I have spent enough time watching the Weather Channel folks in all their storm gear, standing in a heavy mist, explaining how this was "supposed" to be the storm of the century.
