The 29/00Z GFS/ECMWF deterministic runs generally follow their
means --- and maintain very good continuity through the end of day
6 (6/00Z) --- for the Subtropics and the Hawai'i forecast. What
differences that do occur --- were closer to the eastern Aleutians
and with the outcome of the next cyclone. Being a day 7
observation --- and with little change expected prior to --- these
differences are worth a subtle mention. In that, the outcome of
this higher-latitude cyclone (at day 7) invof 160W may have an
impact on the amplification of the Subtropical Ridge in the
eastern Pacific --- and perhaps a relaxation of the trade winds.
