Actually, Lafayette, La is not within the cone. We are just to the left a bit.
I am also in Lafayette. IF it continues on the path that experts predict, we will more than likely experience rain and some tropical storm winds. If you life in an area that is prone to flooding, you might want to prepare for that. Power outages will be likely, at least in my area, off Verot School Road. Every time we get a minor thunderstorm, we seem to lose it.

You might want to remove light items that are outdoors that could blow around and you would want to make sure you have some bottled water in case of power outages. I don't see a need for evactuaing unless you live in a mobile home, however.
