Not looking good. I'd evacuate ASAP and try to get out way ahead of it and not have to sit in traffic as it closes in. Just not worth the trouble of being there even if it is weaker at landfall. Plus power will go out and you will not be able to work. Grab the laptop and head out of town. Get a hotel room with maid service and kick back, have some fun and do a little work. Oh, and if they haven't shut down purchase fo federal flood insurance buy a policy real quick.
