98-L hasn't developed a well-defined circulation (just yet) to track, and there is no mention of forward speed of the system (as a whole) in the NHC discussion. Sat loop suggests currently moving W/WNW at a pretty good pace while embedded in moderate/strong easterlies.

While I find it hard (ATM) to get on board with the most aggressive models forecasting rapid intensification to a Major 5+ days out, once (if) 98-L gets clear of land and in a lower shear environment while slowing over the high/deep available oceanic energy in the western Caribbean, in total agreement that impressive intensification will be likely.
