Depending on the size and strength of the hurricane, it's not such a bad idea to evacuate even if you're that far inland. I mean during Hugo, even Charlotte, NC was hit. That's a good three hour drive from where it made landfall.
Although Charlotte didn't get it as badly from what I hear, and plenty of people evacuated to to there. But that should give some idea of how far away it can effect.
But closer to the storm than that, and you have a real threat of tornados. We were roughly 30 or 40 miles inland, and we lost count at 18, it was just one after the other.
It's not just storm surge, people inland have to worry about tornados. I guess they don't tell you that unless you've been in one.
OTOH, was it Fran or Bertha, I forget, but according to the Weather Channel we were "not in the clear" and it was a beautiful sunny day with a slight breeze. I remember dad getting out of his car pretending to lean against the wind.
So hurricanes are funny beasts. You can be far enough inland that you don't generally worry about these things, and get hit in a way you don't expect, or absolutely nothing happens.
Just a case of being prepared, but not being a chicken with your head cut off either.
