.Synopsis for Hawaiian coastal waters...
High pressure northeast of the state and a trough of low pressure
to the northwest, will keep a fairly stagnant pattern in place
across the marine area through the weekend. Moderate to fresh
southeast winds will prevail over the eastern islands, while winds
remain light and variable over the western end of the state. An
approaching front may bring increasing southerly winds, heavy
rainfall, and thunderstorms to much of the area by the middle of
