.Synopsis for the Hawaiian offshore waters...
High pressure to the northeast will weaken and track eastward
over the next couple of days as a front moves across the North
Pacific. As this occurs, winds will gradually weaken. In the wake
of the North Pacific front, a new area of high pressure will
become established north of the islands this weekend, though
trades will remain in the moderate to fresh range. Isolated
thunderstorms possible for the western waters through Friday.
