Although you haven't heard much about it on the news, there's a tropical disturbance south of Jamaica moving westward into the Caribbean, creating a lot of locally heavy rain and wind, that NOAA is predicting could become a tropical storm on Tuesday or Wednesday.
Royal Caribbean though is one step ahead of you and has already rerouted ships to keep them out of the way of the likely storm and smooth out the ride for passengers.
Details appeared in the August 1 edition of Cruise News Daily.
