Hurricane Jose, Tropical Storm Lee, and Tropical Depression 15 are currently active in the Atlantic. Jose is no longer a threat the Caribbean at all, and Lee is forecast to remain a tropical storm and head northwest, but TD 15 could become a named storm this weekend and if so would be a threat to the Lesser Antilles. The NHC is currently forecasting a 90% chance of this - so people should be paying attention and be ready to make preparations quickly if need be.
This storm could - and again could - this is only a long range forecast, become a hurricane and impact several of the same islands that bore the brunt of Irma.
