These types of hurricanes usually are fairly stable in intensity; thus, only a very slow weakening is forecast, much slower than guidance. it should be noted that this was forecast yesterday, and we had steady intensification. it must be noted that the GFDL and GFDN indicate intensification to cat 2 intensity, with GFDN very close to cat 3.
A few days ago I would've bet a million dollars if someone said that Epsilon would become annular that he/she would be wrong.
I think he's saying if, because looking at that sat above, that would be the ugliest annular hurricane I've ever seen. It's kind of lopsided, too.
Well you could be right, as there has been some erosion of the southwest side of Epsilon. It should begin to REALLY weaken within the next 12 hours.
As for how Epsilon has maintained itself, the fact it started extratropically may hold some clues. It might be more depending on the difference in temperature between the water and the air, more like an extratrop storm which uses the temp difference between air masses than really using the little available latent heat so far north.
