I keep losing track of how that works and what gets new names or doesn't.
But I keep losing track of my own fingers too.
It's actually quite simple. After 2000, systems that move from ATL to EPAC and stay a tropical cyclone all the way across KEEP their names. If a system degenerates over land (like Katia for example) and the remnants regenerate, it gets a new name. Regardless of whether it stays a TC or de- and regenerates it gets a new identifier.
So in this case, it would be the remnants of 13L KATIA regenerating into 15E MAX.
If she stayed a TC over Mexico, it would've been 13L KATIA -> 15E KATIA.
The latter thing happened last year with Hurricane Otto.
Before 2000, basin-crossing TCs did also get a new name, but that was changed by the WMO.
Edit: Of course all of the above is also applied when a storm crosses from EPAC to ATL.
