The remnants of Hurricane Marie are expected to slowly drift
westward over the next several days, and reach the general
vicinity of Hawai'i by Sunday as an inverted surface trough.  The
subtropical ridge centered near 35 degrees north is expected to
gradually move eastward, with a weakness in the ridge developing
by early next week north of the state.  The EC mean is displaced a
little to the east with this overall pattern compared to the GEFS
mean.  By the end of the forecast period next Thursday, a
quasi-stationary front should still exist north of the state, with
the GEFS mean slightly faster.  No major surges of deep tropical
moisture from the ITCZ is currently expected, and shower activity
should be light and across the favored terrain.
