Generalized Statewide Coastal Waters Forecast for Hawaii
National Weather Service Honolulu HI
1008 AM HST Sat Oct 21 2017

.Synopsis for Hawaiian coastal waters...
A subtropical ridge north of the area will push south over the
islands on Sunday, quickly weakening the trades and turning our
winds more toward the southeast. Kona winds from southerly
directions will develop on Monday as a cold front approaches the
islands. The front will push down the chain early in the week,
accompanied by heavy showers and a chance of thunderstorms. Strong,
gusty, erratic winds could accompany these storms. Winds will switch
to moderate to fresh northerlies after the passage of the front.
