.Synopsis for Hawaiian coastal waters...
 High pressure northeast of Hawaii will weaken and track eastward
over the next couple of days as a front moves across the North

coastal waters will 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.
