Good point. I think what is going on is based on windfield. I think if they're seeing a central area of high winds they're going ahead and declaring it a tropical system, despite the hybriid aspects that exist. Some of the forecasters there don't think that's entirely accurate, but they're going along with it for the sake of consistancy.

I'm just hypthosizing, but I think we're also having trouble with these storms because they are in a cyclonic envelope, which ruins a storms appearance, as the outflow has real issues getting developed in such an environment.

Anyway, hopefully this helps
