Are you sure that it is moving at 115mph or is it that the winds are 115 mhp? I had read that hurricanes move at about 10-15 knots and that newer cruise ships are able to avoid them because they can travel at 20-22 knots.
This year the forcast is that there will be storms than last year, but its hard to say which way they will head. Out to the Atlantic would be ideal, but probably wishful thinking.
Read a post a few minutes ago that Grand Caymen and Cozumel are both under hurricane advisories and that in both areas businesses are shutting down to prepare.
