Morning models struggle to find Don other than the GFS Parallel and the hurricane models HWRF and HMON (Replacement for the now retired GFDL).

The range of difference in the hurricane models is from open wave to category 2 hurricane (after it passes over the Windwards). If the system reaches 12.5N or higher conditions are hostile enough to make the open wave more likely, if it manages to stay at a low altitude it has a shot at hurricane strength. Either way Don (and the wave behind it) are likely to be short lived.

Today however, the Windwards should be watching for it approaching from he east later tonight. The small size means some folks will barely feel it while others may be hit by a intense bit of storm which are very difficult to predict.
