The rest of the area seems to be opening this afternoon, if it hasn't already. E.g. Chik-Fil-A on Universal Blvd was closed for breakfast but opening for lunch, I-Drive trolleys start running today at 3, I think airport reopens around noon. My guess is HHN is a go for Saturday. Biggest concern would be checking with your hotel to make sure they weren't flooded out and aren't overbooked.
