An area of disturbed weather in the Caribbean Sea has a 40 percent chance of developing into a tropical system sometime in the next seven days, according to the National Hurricane Center. If the storm develops, it would be named "Sara", and most likely drift over Central America before dying off next week. However, at least one computer model has the storm strengthening and moving northward, eventually arriving in Florida in a week's time. At this point, it is too far out to say with any real certainty, but it's a feature in the atmosphere worth keeping an eye on.
