Re: Andrea Strengthens Overnight

Andrea's structure is subtropical with everything well away from the center and has been since day one. Any strengthening was likely due to some baroclinic processes as Andrea is interacting with the upper level trough immediate to its west. Wind shear analysis clearly show Andrea being sheared aloft at this time.

When in doubt, take the word of the National Hurricane Center.
