Don't pay any attention to the weather reports. That is how the predictions are given this time of year. Storms... everyday. That is because everyday about 2 or 3 o'clock you will get a ran shower. But like Penny said it only lasts 20 to 30 minutes. So they put storms in the forecast everyday. The only things you have to be concerned with are tropical storms and hurricanes. But it looks like you are in good shape in that area. You'll have a good cruise.
