It means, Deb321, that that wave is expected by all of the global models to make it to the Bahamas and Florida in 4-6 days. Not to be alarmist, but it has a good circulation, convection is starting to fire up around it, and it has 4-6 days of fairly warm water and good conditions before it reaches the US. What it will be by then is anyone's guess, and whether it enters the Gulf is too, though if it does, cold fronts at this time of year might not let it get very far into the Gulf. Just pay attention to it and be prepared.
