Model runs for don are mixed, Don is a very small storm, and thus could change in intensity rapidly. In fact HWRF and HMON models show it reaching hurricane intensity before the Windwards, however other models do not . The globals aren't handing it well right now.

But for the 0z models, GFS Parallel is showing it holding together and strengthening passing over the windward islands late Tuesday night. then falling apart before reaching Nicaragua.

GFS Operational isn't getting a good grasp of it (too small).
