The upper level low currently situated northwest of Hawaii is
expected to gradually weaken over the next few days, having little
effect on the state.  Meanwhile, the core of the surface high is
expected to reside between 40-45 degrees north through the
weekend, with the strongest trades and pressure gradient likely
north of the Islands.  The ridge axis should be closer to 35
degrees north by early to middle portion of next week, and this
will tend to increase the trades some.

Hurricane Linda in the eastern Pacific is forecast to track
west-northwest over the next several days and gradually weaken
over cooler waters as it approaches the Islands on Sunday.  The
official track takes the storm a couple hundred miles north of the
state as it weakens to a tropical depression.  The latest runs of
the ECMWF and GFS brings rainfall from this system near the
northwestern Islands early next week.
