Just had a "Severe Weather Report" on the local news. They showed sustained winds in Wilmington at 36 with tropical storm gusts to 55 right now. It sounds like it's starting to pick up. I know that you can't live in Wilmington and not know how to prepare, so I'll spare you that, but just take it easy. It's crawling along so I'd expect you guys get more flooding than wind damage. High tide is going to be a little scary I bet.
Just an FYI, but NC has issued mandatory evacuation for a couple counties up north of you, Dare and Currituck - they're calling for 10-15" of rain in those areas with storm surges 6-10' up there.
We don't expect any real problems here. 30-50 mph sustained with gusts to 50-65 and 1-3" of rain with tidal flooding. I guess there's a reason why these build waterfront homes on pilings afterall, eh?
Stay safe and make the best of it.
