Has a hurricane or cyclone ever reformed after passing over a large land mass?
Since you don't seem interested in Atlantic-Pacific crossovers, of which there are several good examples.....

2004's Hurricane Ivan made landfall on the Gulf Coast, degraded into a tropical depression and was eventually declassified while crossing the southeast US. After coming back into the Atlantic, Ivan tracked back south, re-formed into a tropical depression, then hit the Atlantic coast of Louisiana.



The key was the southward track in the Atlantic. Hurricanes weaken when they're that far north; they're away from the warm ocean waters that generated them in the first place.  But because Ivan tracked south into warmer waters it was able to strengthen a little. It may have been pushed by a cold front. But also, the next hurricane, Jeanne, was already approaching Florida, so Ivan may have been sucked into the circulation around it. Jeanne did its own loop-de loop out the in the Atlantic, so the jet stream may have affected both.
