Re: ATL: IRENE - Models
Animated 18z GFDL - takes it south of JAM. Looks overdone on the ridging but maybe its a trend. We'll see with the 00z model suite.

clfenwi, thats of course assuming the system doesn't decide to relocate towards the convection, its pretty xommon thing in these developing systems afterall...
If that were to happen then those models would be too far south...
Funnily enough the GFS is abit further north already by 06z at 16-16.5N roughly.

Re: ATL: IRENE - Models
From JB:
Irene has developed, and I have no changes... its a Florida/Se threat where the preseason impact forecast was centered

SFLcane, exactly the same track as the ECM, like identical!!
Strengthening hurricane heading up the east coast of Florida, not a great track for Florida OR GA/SC.
Most models take the path of *least strengthening*.

18z GFS Ensemble members...only 1 east of Florida now...almost all into the Panhandle
Also notice the bend further left of the operational
