It's very strange. Extremly very little circulation (50-60 km) and discrete convection over center.
This storm is very midget, Also for the 12 km models resolution.
19-20°C Sea surface
A ship report 30 kt wind at 20 km to center. For this little storm, I suppose, the most intense wind (40- kt) at only 10 km around the little center.
subtropical depression?
