.Synopsis for Hawaiian coastal waters...
Fresh to locally strong trades will persist through tonight then
gradually shift to the NNE and diminish through the middle of the
week in response to Hurricane Fausto passing north of the islands.
The trades will then ramp back up to fresh and strong levels late
this week into the weekend as Fausto continues off to the west-
northwest away from the state while strong high pressure builds
north of the islands. Moderate to large east swell associated with
Hurricane Fausto will continue to rise tonight and peak
potentially Monday night into Tuesday.
