My wife is 7 months. She has been having contractions because she is pretty stressed out. The house might be able to take the winds but I am not going to find out.
The worst part after Alicia was not having power for 4 days. It was blazing hot 90 degrees + and humid. It was miserable. I can't imagine my pregnant wife or kids being able to put up with that.
Please get on out of there early, especially if she's already having contractions from the stress! You don't want to take the chance that she'll go into labor early while you're in an area with no power, no potable water, and possibly no functioning hospital!
Good luck!
