Thought I'd point out how similar the T+240 charts are for the GFS and
the ECMWF at 06Z / 00Z respectively, regarding Hurricane Bill.

Both have Bill flirting dangerously with the eastern seaboard of
Canada before weakening and then explosively developing in the
westerlies in the mid-atlantic as it recurves out to sea. ECMWF 945mb,
GFS 960mb.
