BTW, this really isn't an ERC, but dry air entrainment. Okay, sorry my thoughts don't flow, but what I meant is that WPAC typhoons get this look many times.
Ioke was really the classic WPAC STY, in a relatively unfavorable location for one. And now another system seems to be forming to the southeast near the Date Line, and it has good model support. Sorry to get OT, but if that's not a sign of El Nino, I'm not sure what is.
I wonder if any Atlantic hurricanes go from pinhole eye to large eye after the ERC? I know Wilma did that.
