Having gone through Rita in 2005 and Ike in 2008, I understand your concern about how a hurricane may affect your home. Hope everything goes well for you and that Irene's impact on you is slight.
DVC has a hurricane policy that you can read on the member website (see
https://dvc.disney.go.com/dvc/member/memberDetail?id=MemberHurricanePolicyDetailPage). It appears that you have some options that might help you save your points, or at least reschedule your vacation. I suggest you call MS to see what options you have.
Good luck!!
Here's the entire Policy as of today:
