Carlg beat me to it, but Welcome aboard! Its always good to get new memebers to chat with. The others have already said it, but the truth is, unless the Huricane comes in on embarkation/debarkation day, it is rare that a cruise gets cancelled by a storm. Even then, they may just postpone it. If they do you will get your money back, so you will be out a vacation but nothing else. If there is a storm projected to go through your cruises course, the cruiseline will re-route you (possibly going to different ports) to stay clear of the storm. So are you taking a big risk? No I don't think so. Just watch the weather before you cruise date (I like the NOAA web site for storm tracking) and visit the cruise website to watch for change update postings and you will be fine.
