I don't think the rain is what you have to worry about. Probably won't have 145 mph winds where you are, but I'll bet they are gonna be strong! I doubt the WSM could handle anything over 35 mph.
I was kinda dissapointed. I was hoping the hurricane would hit Louisiana and come up through Tennessee. We had 2 hurricanes do that in 2001, got 5 inches of rain apiece out of them. It is a nice day here. The high is 70 degrees.....IN AUGUST!
